Solar panels to run AC [1,1.5,2,3,4 5Ton]
Solar panels are trending since 2014 and since then more and more people are showing interest in them. The questions related to solar panels become more and more exciting. I find excited about these questions is most people are concerned about how many solar panels are needed to power their heaviest load. And for most of the time, the heaviest load in a home is Air Conditioner.
Here I am going to answer one of my favourite questions which is “How many solar panels are needed to run an AC?”
For each one ton of capacity, AC consumes 1 unit of power per hour and to run the same for 8 to 20 Hours daily with solar panels you will need 5 to 12 numbers of 330 Watt solar panels with a grid-tie inverter and net-metering. Also, we can say that you will need a 1.6 kW to 4 kW grid-tied [also known as a grid-connected] solar power plant with net metering.
Since batteries are still expensive and they need time-to-time maintenance as well as replacement. It is not recommended to go with a solar power plant having battery backup (these solar power plants are also known as off-grid solar power plants, learn more) as long as grid power is available.
What is a Gird-tied solar power plant?
Sunshine is available for 5 to 8 hours only but our requirement for electricity is for 24 Hours. To use solar power for 24 hours of requirement we need to have a solar power plant big enough to produce excess power more than our daytime requirement and a way to store this excess power for night usage.
To store this excess power, batteries could be an option, but storing electricity in batteries is still expensive. The reliability of solar energy is completely weather-dependent, leading us to blackouts on certain days of the year.
To overcome these issues, string inverters (also called on-grid or grid-tied inverters) have been developed, which convert DC (direct current) power generated by solar panels into AC (Alternate Current) power in synchronization with grid power.
A benefit of synchronization of solar power with the grid is that if we generate more power excess than our daytime requirement, this excess power can reverse feedback to the grid. In simple words, excess power from the solar power plants will be exported to the grid.
And this exported power will be subtracted from the power you will use at night. Hence your gird will become a huge battery for you and you don’t even need to pay for it.
When the sun goes down, a gird-tied solar power plant becomes unable to produce electricity. Hence we need to use the power from the grid and the amount of power we use at night will be compensated by the power we injected into the grid during the daytime.
The above diagram shows the typical connection of Grid-tied [on-grid]
Now, to subtract the power exported to the grid from the power imported from the grid, you will require “Net-metering”.
If the net-metering is not available in your state and you are looking for a battery-less on-grid solar power plant. I highly recommend you to read our blog on “Solar without net-metering”.
Power consumption by AC [1 ton, 1.5 ton, 2 ton, 3 ton, 4 ton and 5 ton]
As I already mentioned each ton of AC consumes 1 unit of power per hour, which means that if you want to run a 2-ton AC for 8 hours per day the total power consumption by the 2 Ton AC in a day will be equal to [2×8 =] 16 unit [or 16kWh].
Similarly, we can calculate the power consumption by different ratings of AC [that is 1 ton, 1.5 ton, 2 ton, 3 ton, 4 ton and 5 ton] running for different hours daily. Refer to the below table showing the same.
As you can see from the above table running an AC is very expensive and installing a solar power plant to run it will be expensive too.
Whether solar panels are in your budget or not I highly recommend you to read our blog on “15 low-cost tips to reduce the power consumption of AC”.
Sizing of Solar panels to run AC
Power generation from solar panels is dependent upon the sunshine time, pollution level shadow free area and tilting angle.
Now considering, a 100% shadow-free area, low pollution level, and right tilting angle then 1kW of Solar panels (330Wat x 3) will generate 5-6 units of power in 7 to 8 hours of sunshine.
To run 1 ton of AC for 8 hours, you will require number of solar panels that generate (1 x 8 = 8 Units) 8 units of power [that is 8kWh] per day. Hence the size of a gird-tie solar power plant required to generate 40 Units of power = 8/5 = 1.6kW
Solar panels come in various sizes like 330Watt, 325Watt and 360Watt etc, so the numbers of solar panels required can be different for different ratings of solar panels.
Since 330Watt of solar panels is popular these days, we can conclude that 5 numbers 330 Watt solar panels are needed to run 1 ton of AC for 8 hours daily.
Similarly, we can calculate the size of the grid-tied solar power plant needed to run different capacities of AC for different time periods. Refer to the below table showing the same for ease of your understanding.
Solar Panels need to run 1 Ton AC
To run a 1-ton AC for 8 hours a day on solar panels you will need a minimum of 5 numbers, 325 Watt solar planes and to run the same for 12 hours a day you will need 7 numbers of 325 Watts solar panels.
Solar Panels need to run 1.5 Ton AC
To run a 1.5-ton AC for 8 hours a day on solar panels you will need a minimum of 7 numbers, 325 Watt solar planes and to run the same for 12 hours a day you will need 11 numbers of 325 Watts solar panels.
Solar Panels need to run 2 Ton AC
To run a 2 ton AC for 8 hours a day on solar panels you will need a minimum of 10 numbers, 325 Watt solar planes and to run the same for 12 hours a day you will need 15 numbers of 325 Watts solar panels.

First, let’s define an Inverter
What is an Inverter?
Basically, Inverter is just a form of UPS but with longer backup time. It has an input source connected to mains from public utility source, or a Generator. The AC supply is converted to direct current (DC) by means of a rectifier on the Inverter circuit to charge the battery, which is DC. The charged DC battery is then inverted back to AC (Alternating voltage) via a step up transformer, which is what supports the load (equipment) during power outage, hence the name INVERTER. Ther are other Inverters too that do not incorporate the use of isolation transformer, they are called Transformerless Inverters.
Apart from the runtime, there are other features that distinguishes an Inverter from a UPS.
First, the switching time between the UPS and some Inverters differs.
Switching time for UPS is in the range of 0.5mS to 5mS, while for Inverter, it may range from 20mS to 500mS. This wide time lag may be noticed as power interruption by sensitive equipment.
While UPS is built primarily for short time data protection when there is power interruption, because it can perform voltage regulation at the output, some low grade offline Inverters on the other hand are intended primarily for backup only, but not equipped for smooth transition between power interruptins. In other words, they are not equipped with interruption-free circuits. they use some system of relay for switching. Such Inverters cannot guarantee data protection especially during power fluctuation or when power is out of range. It is simply garbage-in-garbage out meaning, whatever voltage comes in is what it gives out at the output. If the input voltage is poor, the output voltage will also be poor.
Since there is no real switching taking place in an online UPS, it is recommended to connect very sensitive equipment, like servers, switches, computers and other communication equipment to UPS/online Inverter.
Secondly, Inverter operates with external batteries because of their size in contrast to UPS. The size of charger in Inverter enables them to charge larger size and number of external batter(ies) than the UPS would do hence, Inverters are further distinguished by the size and number of batteries they can be operated with, which also determines the runtime during power interruption.
In summary, all UPS contain inverter circuit within them, but not all Inverters perform voltage regulation that ensures regulated power during interruption, as UPS would do. Also, while Inverters can backup for hours or days, UPS may only last for minutes or few hours, their major design is to retain power temporarily and prevent interruption only until the main power source is restored.

Now, let us go into details and what to do to resolve each of these problems one after the other.
(1) Inverter Not Charging:
There can be lot of reasons why the Inverter may not charge,
- No power supply: When you notice that the Inverter is not charging, the first thing to do is to:
(i) Check the power source to be sure that power is available. Be sure power is available from Public utility source of Generator. If available, check the breaker between the power source and the Inverter
(ii) Check the fuse in the plug, where plug is use to connect Inverter to mains power source and replace if blown off ( but be sure to detect what caused the fuse to blow off and correct where necessary).
(iii) Ensure that the input socket and plug are ok, and where the input connection is via a connector, ensure there is no loose or disconnection of the input cable(s).
(iv) Check the continuity of the input cable, to be sure the cable supplying power to the Inverter is not broken.
- Bad input Voltage/frequency: If the input Voltage or frequency is too high or too low for the preset value of the Inverter or there is power fluctuation, the Inverter will delay to accept the supply. Bad voltage may be corrected with a Voltage Regulator installed at the input of the Inverter, but the frequency has to be corrected by the public utility supply Authority or on the Generator. The correct Voltage and Frequency values and window of allowance depends on each country’s standard. You may set the Inverter to accept wider voltage/Frequency window if equipped with such option.
- Blown fuse: The Inverter may also not charge if the input fuse is blown or the breaker trips due to fault. Since breaker cannot just trip or fuse blown without a cause, the cause of this has to be ascertained before the breaker is reset or fuse replaced. In replacing the fuse, the fuse must be replaced with exact same rating otherwise, a major damage will be done to the board in case of another fault.
- Wrong Connection: If the line and neutral or earth cables are interchanged, the Inverter may not charge but come with error message on the display. Ensure that the Live cable go to the live terminal of the Inverter and Neutral to the Neutral terminal, same to the earth. Also ensure that the battery polarity is correct. If the battery is not connected or the battery DC breaker is not ON, the Inverter will not charge. Wrong connection can cause a major damage to the Inverter, therefore ensure that a qualified Technical personnel is employed to handle your Inverter installation.

- Inverter fault (Board issue): In some cases, especially if the Inverter is not well protected from surge, there may be some failed or blown component on the Inverter board due to surge, it may also cause the Inverter not to see the input. Refer to product vendor or qualified Technician for repair. You may also contact Shrego ProBTech for assistance if you want to save cost.
- Battery full: In some Inverters when the battery is charging, the Charge indicator blinks but stops blinking and remains steady when the battery is full or near full, some customers inteprete this to mean that the battery is not charging. When the battery is full, the battery indicator stops blinking and remains steady, until there is a drop in the battery’s nominal voltage.
To confirm if the Inverter is charging, switch off the input to the Inverter and drain the battery a bit, say for 10 minutes or more then return, power to the input, the indicator should start blinking again for a few minutes before stopping again.
(2) Battery Problems
Battery is the major component of Inverter that needs to be carefully selected from reliable shop as their replacement is very costly and success of repair cannot be guaranteed.
When battery fails, one or more of the following can be responsible:
(i) Battery Under Charged/Over-Charged: Every battery has its charge/discharge cycle. A battery that is continuously under-charged or over-charged cannot maintain its rated lifespan. Most of the modern day intelligent Inverters have over-charge or over-discharge cut-off sensor that ensures that the batteries are not unduly over-charged or discharged. However, most of the cheap (sub standard) Inverters in the market are not equipped with this intelligent device, which causes the batteries to boil when over-charged or cause suffation to set up when the batteries are constantly over-discharged and are not constantly kept at full charge. For batteries to serve their stated lifespan successfully without premature failure, they must be maintained kept charged at all times after use.
Another thing to consider is that, batteries must not be over-discharged. In-fact, batteries are not expected to be discharged below 0.5V per cell, i.e. for a 12V battery, minimum voltage to discharge the battery must be around 10.8V ( for the conventional batteries). Once it is below this, most intelligent Inverters will begin to beep to alert that the battery is low and after sometime shuts itself down completely to prevent damage to the battery. At this point, the battery must be fully re-charged before use, even if the machine fails to shut itself down. Many battery users complain of early failure of battery because they don’t know or follow this simple maintenance instruction.
Since it is not all Inverters that are equipped to shutdown or prevent over-dis/charge, it is advisable to seek technical personnels’s opinin before shopping for an Inverter; otherwise untimely failure of batteries will be a constant issue.
(ii) Battery Charges/Discharges fast: If the battery shows full charge too early meaning, it reaches its full charge earlier than usual, which consequently also determines the discharge rate, it may be the first sign that the battery is getting weak. A strong battery takes longer time to be fully charged and also longer time to discharge. However, in a battery array that involves two or more batteries joined together, failure of one battery in the string may affect the performance of other batteries in the array. The strength of all the batteries in a string is determined by the capacity of the weakest of them in the array. This also explains why weak and strong batteries should not be combined in a battery array. This shall be explained further under battery maintenance.
Another important thing to consider is when battery discharges faster but takes longer time to be fully charged. In this case, you need to evaluate total load connected to the Inverter to find if there is a hidden heavy load draining the battery. If a battery takes a long time to be full but discharges faster than expected, it may mean that there is too much load feeding from the battery. Shed some heavy loads and observe any difference.
(iii) Battery Low Volt: When the battery voltage becomes too low, lower than the normal voltage then it is time for replacement. One of the symptoms that will manifest is that the battery discharges faster than usual and also complete it’s charging process earlier than usual. When a battery shows full charge within a few minutes of charging, it is time to call a battery Technician to evaluate the voltage level or the electrolyte level, in case of tubular battery. For wet cells, electrolyte level must be checked every three months and it must be above the cells level. No other water except Distilled water must be used to refill the cells, otherwise corrosion of the cells and consequently failure will result. Most of the modern day Tubular batteries are designed with float indicator that measures the electrolyte level on each cell, when the electrolyte drops below the marked evel on the float indicator, it is time to top up the electrolyte,
Dry cells are maintenance-free, so all they need is to be operated under cool temperature and be constantly in charged condition.
Another problem that can cause battery to have low voltage is when the battery has been left in a deeply discharged condition for long without recharging, it develops what is called suffation which may be irreversible, and it may be impossible to revive such a battery again. A dry cell battery loses 2% of it’s voltage every 30 days if left in a discharged condition, while wet cell self-discharges as much as 10-15% monthly, that is why battery must be fully charged if it is going to be left unused for a long time. The shelf life of battery is very short, that is why it is not advisable to buy battery and keep for a long time if it is not going to be used. If a bettry is not going to be used over a long period of time,it is advisable to have it charged after every three (3) months and stored in a cool place. Heat helps in self-discharge.
(iv) Reversed Battery Polarity: Reversing the battery polarity will cause damage to the Inverter, especially the one that is not adequately protected. Care must be taken to ensure that the positive terminal of the Inverter cable is terminated on the positive terminal of the battery and ditto for the Negative (-) terminals. Also for batteries in series or parallel, the polarities must not be reversed. It is always advisable and safe to allow a Technician handle every battery installation.
(v) Corroded Battery Terminal. Corrosion of battery terminals is one of the causes of poor battery charging as the corroded materials forms a thin film of insulation between the battery terminal and the connecting cables hence reducing the current flow to the battery from the Inverter.
To reduce this effect, you can apply petroleum jelly on the battery terminals after scrapping off the corrosive substance or immediately after battery installation.
(vi) Swollen/Hot Battery. This is a situation whereby the battery gets swollen or bulges out as a result of failure of the battery. Such battery should be isolated from the array and replaced immediately.
When battery is charging, try and feel the temperature from the casing of the battery, if the Inverter is not equipped with battery temperature sensor. If battery gets unnecessarily hot, please, call a Technician immediately. A battery that hot during charging can explode, causing electric fire.
(vii) Loose battery terminals. If the battery terminals are loose, high resistance will be built around the terminal that will prevent or reduce the flow of charging current to the battery. This can result to arching (sparking) around the terminal and in extreme cases can result to fire. Ensure all battery terminals are firm.
(viii) Battery Electrolyte dry out. Tubular or wet cell batteries, unlike dry cell (maintenance-free) batteries needs periodic maintenance. The electrolyte level must be closely monitored and must not be allowed to dry out otherwise, permanent damage may be done to the battery cells and consequently failure of the battery.
(i) Loading above the rater Inverter capacity. Basically, most low grade domestic or industrial Inverters are designed for light loads- such as lighting, electronics appliances, and fan. Heavy high wattage equipment, like refrigerators, heating appliances, ovens, Air conditioners, electric motors and pumping machines are not practically suitable for low grade Inverters. Apart from some of these appliances drawing very heavy current from the battery causing it to run down quickly, their starting current can be a burden on the Inverter, causing it to shutdown under over-load condition or even burn the machine board. When calculating the loads to be connected to the Inverter, the total expected (maximum demand) load must not exceed the rating of the Inverter. Allowance also must be given for future load additions or for redundancy, so the rating of the Inverter must be a little bit above the expected maximum load demand, like 20% higher.
over, when calculating the total load, which is the sum total of all the watts ratings of each appliance to be connected to the Inverter, consideration must be given to the difference between the Wattage rating of the appliances normally written on the name plate and the KVA rating of the Inverter. Kilowatt is not the same as KVA. The efficiency value and power factor of the Inverter must be good. Since there is a difference between (Kilowatt (KW) Volt Ampere (VA) and Kilovolt Ampere (KVA), and most of the appliances are rated in KW while most Inverters are either rated in VA or KVA, some mathematical conversion has to be done to determine the actual kVA capacity of the machine. For further information on suitable Inverter size to for your installation, you can contact Shrego ProBTech.
Please, take note that some Inverters are also overrated that is, they are rated above their real capacity. For instance, an Inverter that has a label of say 2kVA can in real sense be just 1.5kVA or less. Some bubious sales persons even remove the manufacturer’s label and replace with cloned label with higher rating. This is very dangerous and that is why it is advisable to consult a Technical personnel before shopping for Inverter as well as every other electrical appliance.
Point To Note: Inverter or UPS should not be loaded above 80% of its rated capacity for three basic reasons:
One, possible future expansion of load.
Two, maximum efficiency of the machine. Loading machine to full load will lead to low efficiency (performance) and consequently pre-mature failure.
Three, many of the Inverters are overrated, and so may begin to show overload indication even at less than 80% loading.
(ii) Short-circuit condition. Another thing that the Inverter can sense as overload is when there is a short-circuit on the line. When there is a bridge between the Neutral and the line (live/hot) cables, the Inverter sees it as overload because it will be drawing very heavy current more than what the Inverter can handle.
(iii) Inverter Fault. Inverter can also show overload as a result of internal fault on the circuit board. Refer to competent Technician for repair.
(iv) Battery Low Volt. Another fault that inverter can translate as over-load is battery low volt. When the battery voltage drops below the preset value for the Inverter, it may cause the Over=load light or display on the Inverter screen to come up. If after recharging the battery the fault clears, then it is low dc voltage otherwise, go further with the possible conditions stated above
(4) Wrong Circuit Wiring and Cable Sizing:
Before installing Inverters, care must be taken to the theoretical calculations involved in selecting cable sizes and types as well as international standard cable colour codes, how the machine is connected to the load and the supply source. Wrong cable size is a potential fire disaster, loose termination and wrong wiring is another accident waiting to happen. Most fire incidents in homes and offices are caused by loose terminations or wrong (low grade or under-sized) cable. (see my note on Common Causes of Fire in Homes and Offices) for details on this. The current-carrying capacity as well as the colour codes of the cables must be carefully selected. There are American, British, German etc colour codes for cables which must be religiously followed. Also, the size of the input and output receptacles (sockets and plugs) must be adequate for the load demand of the machine. Breaker(s) or fuse of suitable sizes must also be incorporated at appropriate places for protection of not only the equipment but also humans.
Inverter load must be completely separated from the rest of the loads in the installation and appropriate isolation and protection devices such as MCBs and ELCBs must be used both for the input and the output of the Inverter. The ground cable of the Inverter must be terminated on the earth bar of the building, which must in turn be buried to the general mass of earth.
(5) Inverter Displays Utility Failure (Battery Not Charging):
This problem occurs when the Inverter cannot get supply from the source. When this happens, the Inverter can only run on battery mode but cannot charge. This is accompanied by a beep sound that repeats itself every second (depending on Inverter configuration). A lot of things can be wrong, some of which are: blown fuse or tripped breaker, unavailability of supply from the source or bad input frequency or voltage. Another thing that can be responsible is a broken cable or open-circuited transformer.
The first thing to confirm when the Inverter displays utility failure or No input is: Availability of supply from the source.
Check the fuse/or input circuit breaker.
If plug and socket is used to connect the input to the power supply source.
Check the plug and the socket to ensure there is no loose or open connection and also ensure the fuse on the plug is ok.
You can also carry out continuity and short circuit test on the supply cable (to be done by a qualified Technician).
You may need to test the isolation transformer as well and surge module if available.
In the case of blown fuse, fuse don’t just blow, it is caused by a fault. The fault can be transient or permanent. You must first establish the anomaly that caused the fuse to blow in the first place before doing replacement, otherwise the same fault if not cleared will blow the fuse again and may cause further damage to the inverter. You may replace the fuse with the same current rating as the blown one or refer to a qualified Technician for replacement. Don’t use overated fuse otherwise, you may damage your Inverter. If the Inverter is equipped with a circuit breaker instead of fuse, you may reset the breaker only after the fault that triggered the fault is cleared.
In complex cases, the surge circuit of the Inverter might have been affected or some other power components on the board, in which case you will need to refer to your product vendor, Inverter Technician for repair, or simply call Shrego ProBTech for assistance.
(6) Inverter Over heating:
Inverter over heating can be caused by many things, but the most common cause is fan failure or overload. The purpose of the cooling fan in an Inverter is to provide a means of cooling for the electronic components on the board, which generates heat when in operation. The fan does this by dispersing this generated heat to the neighbourhood. When the fan fails,or the enviromantal temperature is too high, the heat buildup can cause these semi-cnductor components to explode and fail. For this cause, ensure that the room where the Inverter is installed allows for cross ventilation and is spacious.
Therefore, at every point in time, the fan must be working when the Inverter is in operation and heat is being generated. Most Inverter designs are equiped with thermostat such that the fan stops blowing when the Inverter senses that the room temperature is normal, the battery has passed the bulk charge stage and the load is minimal.
If it is the cables that are overheating, then the cable contacts must be examined for partial contact (loose connections) or overload.
Over-heating can also result from operating the Inverter in poorly ventilated environment.
This can occur when the Inverter is operating under abnormal working conditions. One of this is when the mains Voltage or Frequency is abnormally poor. This is more common when powering the Inverter with Generator. Most Generators usually have poor Frequency and/or Voltage problems which may cause the Inverter to operate under tense condition and can eventually lead to Inverter failure.
Humming can also result when the Inverter is abnormally overloaded or under short-circuit condition.
(7) Output Overload/Short-circuit:
This fault can occur when there is a bridge between the phase and Neutral of the output cables or between phase and earth. In such case if there is no circuit breaker incorporated at the output of the Inverter before feeding the load, this can feedback to the Inverter causing it to fail. If such fault occurs, first of all find a means to isolate the load from the Inverter, then change the cable and return the load back to the Inverter. If there is a breaker at the output of the Inverter, it must trip to save the Inverter.
Overload may also occur when the Inverter powers load more than it’s rated capacity. In such case, the Inverter will beep for some seconds and then shutdown by itself. Ensure that the excess load is removed and reset the breaker.
Some Inverters may also show Overload before shutting down when the battery is too low as earlier stated but, this error will clear off after the battery is recharged. When an Inverter shutdowns as a result of low battery, do not attempt to load the Inverter immediately the mains is present but allow the batteries to charge to some percentage before connecting the load back.
Overload can also be as a result of blown components on the Inverter board.
(8) Inverter On Bypass Mode:
In bypass mode, the Inverter can only supply to the load when mains is present, but shutdowns instantaneously after mains is off. This can happen when the Inverter is not properly powered up.
To power up the Inverter, depress the ON (power) button until the Inverter comes online or follow instructions on powering up. If it fails to come online after the ON button is depressed, then it may be a sign of fault or bad ON/OFF switch or even disconnected signal cable.
Also, if the dc circuit is broken, it will not allow flow of current from the battery to the load.
This may also be as a result of an internal fault within the Inverter.
Please, refer to a qualified Technician or the product vendor for repair,
(9) Inverter Goes Off Few Moments After Power Supply Is off:
This situation is different from Bypass Mode described above as it is not instantaneous. It is a situation whereby the Inverter goes to battery mode when there is utility failure but lasts only a few seconds or minutes, then goes off. In such case, confirm that the battery is ok, because a bad battery cannot retain charge and consequently will also not be able to discharge to the load.
(10) Inverter returns power to the input
When an Inverter returns power to the input, it’s a sign of fault. A damaged relay or AVR can sometimes be responsible among other components. Please, consult your Technician or Shrego ProBTech for help.
(11) Inverter is shocking.
A shocking Inverter may be a sign of failed component that is causing leakage, broken cable that is causing leakage and an unearthed Inverter. First, ensure that the Inverter is connected to the earth, and that there is equipotential (0V) or voltage less than 10V between the Live and Neutral cables.
FACTORS DETERMINING THE EFFECTIVENESS OF INVERTER
There are some factors that determine how effective and durable a good Inverter would be. Under good management, an Inverter is a durable machine which hardly develops fault if operated under suitable conditions.
(1)Environmental conditions: Temperature and dusts play very significant roles in the performance of an Inverter. High temperature causes excessive heating on the transformer and other components of an Inverter. Besides, every 8°c rise in temperature shortens a battery’s lifespan by half.
Inverter must therefore be installed in a place where there is cross ventilation and free from moisture.
Accumulated dusts on the circuit board of the Inverter can also react with moisture to form a conductive film and cause short circuit, thereby damaging the board. It may even lead to fire incident. That is why it is essential to have your Inverter/UPS serviced from time to time by a qualified technical personnel.
You may contact Shrego ProBTech for preventive maintenance whenever you feel your Inverter is due for servicing.
(2)Quality of supply (Voltage/Frequency Fluctuation): If either of the two electrical quantities is out of range, it can affect the performance of an Inverter. Voltage fluctuation may be corrected with an automatic Voltage Regulator/ Stabiliser that compensates for the high or low voltage as the case may be or an Over-voltage cut-off device (Voltage Guard) that outrightly cuts off supply to the machine whenever it goes out of preset range. Allowable AC Voltage for Nigeria is between 220V and 230V, while some machines may still tolerate between 190. 270V depending on the design.
However, unlike voltage, frequency cannot be corrected by Voltage Stabilizer or Over-Voltage cut-off device; it has to be corrected from the supply source, i.e either from the AC Generator or from PHCN. Allowable frequency window for AC machines is 50Hz ±2. When this is out of range, the Inverter/UPS will reject it and the battery will stop charging until this becomes normal again.
I have had cases where clients complained that their Inverter does not backup for long when batteries are charged with Generator but does well when charged with public utility source and vice versa, my response has always been to check the frequency of the Generator being used for the charging which most of the times are far above or below the allowable frequency window. If the Voltage or frequency is higher or lower than allowable range, the batteries would not be charged well and the result will be low backup time.
(3)Wrong Cable Size and loose connection on battery terminals: Wrong size of cable for interconnection of batteries or loose contacts can cause fire and loss of life in the worst case or erratic performance/short battery runtime and lifespan in the least. Correct calculation of the cable cross sectional area to handle the load demand must be strictly ensured. Underrated cable size, especially when strings of batteries are connected in parallel can lead to insulation breakdown and consequently failure of the cables and the batteries.
(4) Inverter Size: It is important to ensure that the loads to be powered by the Inverter does not exceed the maximum rated capacity of the Inverter, otherwise constant breakdown will be the experience.
WHY BATTERIES MAY FAIL EASILY (FOR INVERTER/UPS)
I have been invited by clients to many homes and offices to come and have their Inverter/UPS batteries checked. Most of these clients complain of their batteries being only a few months old and yet failing so suddenly, could be as short as four months old. So bad. Whenever I hear such story, I am always full of pity for these clients who after spending hundreds of thousands on batteries, hoping to solve their power problems still could not derive the best from their investment. It grieves me whenever I hear such complaints. Many of these failures can be avoided if the user is given adequate information on why these early failures occur and how to mitigate against it. That is why I have taken my time to explain some of the commonest reasons why batteries may fail before their designed time.
Whenever a battery fails, it is easy for clients to assume that such battery is sub-standard or maybe it’s a refurbished battery, while this is true in some cases, in most cases it is not. Even some of the best brands in battery can fail prematurely if proper maintenance procedures are not observed.
Battery, like other apparatus is an exhaustible device meaning, it has exhaustible number of charge and discharge cycles, after which it will begin to degrade until the active materials in it is completely exhausted. Apart from this, battery also has a suitable operating temperature under which it must operate, above or below which it will be adversely affected.
Below are some of the reasons why batteries may fail before their designed time.
(1) SUB-STANDARD PRODUCT. There is no doubt that most battery products in the market today as ever are sub-standard, while some of them are refurbished. This is why selection of batteries must be carefully made. Most clients go for just any cheap battery their money can afford or find on the internet and expect to get the best out of them. The fact remains, nothing good comes cheap. If you are looking for something cheap, not like battery because battery is the main strength of your Inverter, without battery, there is virtually no Inverter. If it fails, your Inverter machine is just like an ordinary box. Fake Inverter can be repaired, but not a fake battery. That’s why at Shrego ProBtech, we always emphasize to clients, above other things to leave supply of batteries to us, and some of those who do otherwise have had to call us a few months later for battery replacement, so pathetic. We carefully shop for our batteries from trusted manufacturers directly, that’s why we can afford to give a year warranty with confidence.
(2) CHARGE/DISCHARGE CYCLE: Battery, like any other device has its own number of charge and discharge cycles after which it will begin to show signs of degradation. In other words, it can be depleted after the active materials in it has been exhausted. The time it takes to complete this cycle now depends on how much it is being used. A battery that is being deeply discharged constantly with heavy load may take a shorter time to complete its life cycle than the other that carries lesser loads and maintains full charge at all times. That is why we always advise our clients to avoid as much as possible adding high current demanding loads such as Refrigerator, water heater, electric cooker, pressing iron and Air Conditioner to Inverter. While this may work, depending on the power rating of the Inverter, the rate of discharge will be very high on the battery which may lead to premature failure.
(3) UNDER/OVER-CHARGING: One of the major causes of battery failure is over-charging or under-charging. When battery is constantly under-charged or left in low charge state for a long time, it slowly causes the lead sulphate in the battery to crystallize which results in the battery’s storage capacity being permanently damaged and reduces the battery’s active materials that is responsible for its high capacity and low resistance, this is called suffation. Reversible suffation can be corrected if the battery is serviced early by applying a specific voltage that helps dissolve the crystals thereby bringing the sulphate to its active state, but irreversible sulfation cannot be corrected. It sets in when the battery has been left in a low or discharged state for a very long time. This is why it is not good to leave batteries in the discharged state for a long time.
Continuous overcharging on the other hand can lead to electrolyte boiling and outgassing which will eventually damage the cells in the battery.
(4) LOW ELECTROLYTE: Battery also fail when the level of distilled water in the battery (Tubular) is low. Ensure that the level of electrolyte in the battery is not low at all time. Most of the modern day Tubular batteries are designed with liquid level indicator tht helps to moitor the electrolyte level on the battery cells. Ensure that the water level does not go down below the level marked as Low
(5) SULFATION: This situation as described above occurs when the battery is left in an uncharged condition for a long time. Batteries need to be constantly recharged to keep the sulphate active. A battery loses 2% of it’s charge every 30 days and if this is left for a very long time without recharging, then sulfation sets in.
If a sulfated battery is connected to an Inverter, even if it has never been used before, it cannot be effective again.
SIMPLE TIPS TO PREVENT BATTERY FAILURES
(1) HEAT. Keep heat away. Heat has a very damaging effect on battery’s lifespan and overall performance. In fact, theoretically, every 8 degrees rise in temperature reduces a battery’s lifespan by half. In other words, for instance, a battery which is designed to last 4 years if operated under 25 degrees Celsius temperature will only last 2 years if it is constantly operated under a temperature of 33 degrees Celsius. At Shrego ProBtech, consideration of the environmental conditions under which the battery will be operated is very key, that’s why our batteries rarely fail, more especially if other maintenance conditions as we have advised are also followed. Batteries installed close to source of heat, like kitchen will no doubt fail in no distant a time.
(2) SHORTING THE BATTERY TERMINALS: Some people try to test the capacity of a battery by shutting the two terminals (positive and negative) expecting a sharp spark. This action has a very damaging impact on the battery by weakening the internal cells of the battery, thereby reducing its lifespan.
(3) DIRT AND LOOSE CONNECTION: Dirt at the battery terminal or loose connection may cause high resistance at the terminals of the battery that adversely affects the performance of the battery. Keep the terminals clean and greasy always.
(4) MIXING BATTERIES OF DIFFERENT BRANDS OR CAPACITIES TOGETHER: I once met a Technician who wanted to install two units of 12V batteries in series for a client and mixed one that is 100AH with another that is 200AH capacity. I asked why he was doing this and his answer is simply, He go work meaning, “it will work” Truly this arrangement will work but the ignorance of the gentleman is that while this may work on the interim, the 200AH battery will soon be damaged by the 100AH. The simple logic is this, during the charging process, the charger has a sensor that senses the voltage at the battery terminals which it uses to control the amount of charging current to deliver to the batteries. So when the charger senses that the voltage at the battery terminal is approaching full charge, it reduces the charging current from bulk charge stage to absorption stage, then to float charge stage. So since the charger sees the two batteries as one, not two, while the 100AH battery is full, the 200AH is still hungry for charge, and the consequence is that the 200AH battery will not be able to reach full charge at every point in time, which as earlier discussed is one of the main causes of battery failure.
Also, during discharge the batteries connected in series have the voltage increased, but the current the same, so the Inverter choses the current of the smallest battery, which in this case is 100AH as the current to work with, since it sees the two batteriesas as one unit thereby reducing the backup time. So, it is wrong to mix smaller and bigger battery as well as new and old batteries together. The same is true for batteries of different manufacturers (brands).
(5) QUALITY OF POWER SOURCE TO CHARGE THE BATTERIES: I have heard a lot of complaints from customers that their batteries always perform well after charging with public utility supply but performs poorly after charging with their Gasoline Generator. There are two major explanations for this. They are the Voltage and Frequency. These two electrical quantities are so important to electronics devices that any pronounced variation from the standard will surely affect the performance of an Inverter and other electronics devices. While Voltage variation can be regulated with a Voltage Stabilizer, the frequency on the other hand cannot. So, while the Generator Technician may be able to set a close to perfect voltage during servicing, most of them have issue with adjusting the frequency. The voltage window may range from 220V to 240V, any frequency window out of range of 50HZ ( or. 2) is abnormal and may not be accepted by most of the electronics appliances. The same frequency that may power the Air conditioner, Electric stove, fan, iron or light may not be acceptable by the Inverter because of the semi-conductor components that operates the Inverter.
(6) ELECTROLYTE USED TO TOP UP: Use of poor electrolyte or miniralized water to top up electrolyte in the case of Tubular (wet cell) battery will cause corrossion of the cells and premature failure of the battery.
(7) BATTERY USE AND STORAGE: As earlier stated, if battery is not going to be used for a long time, it should be stored in a cool environment free from heat and in full charge condition. Occassional charging is essential from time to time say, once in two to three months to arrest battery self-discharge. Also, during use avoid over discharging battery and be sure to recharge after each long use/deep discharge.
#1 If your battery is unduely getting hot, it may be a sign of battery failure. Switch off supply from the Inverter and call an eXpert nearby to get it accessed and if necessary replaced. A battery that get abnormally hot can explode and lead to fire outbreak.
#2 Do not use Car battery for your inverter as it is not designed for that purpose. Car battery is designed for quick start as in the case of car starting, and not for continuous use. Besides, it is also not designed for trickle charging that the Inverter provides.
#3 When it comes to battery selection, the size determines the strength, This size comes in form of weigth, as size of the casing can be deceptive. In most cases, the bigger the physical sze and correspnding weight, the larger the AH rating. Typical AH ratings of batteries are: 5AH, 7AH, 18AH, 75AH, 100AH, 150AH, 200AH, 1000AH and so on. These values determine the capacity of the battery. The larger this value, the longer the backup time.
Apart from the AH value of battery, another thing to consider is the voltage. We have 2V, 6V, 12V, 24V batteries. The voltage value determines the number of such batteries to be connected together in a string to give the desired voltage to energize the Inverter.
TIPS ON UPS MAINTENANCE
UPS is an electrical machine that provides emergency power to appliances for a short duration of time when power supply fails. It does this backup with the aid of internal batteries installed in the UPS.
The primary purpose of UPS is for data protection in the effect of sudden power interruption or outright failure. For instance, it prevents computer or server from restarting or shutting down when power surges, sags or outrightly fails, which may result to loss of valuable and unretrievable data.
Some UPS also provide voltage regulation at the output such that even when the supply is unregulated, a smoothened output is delivered to the load. So in this case, UPS also serves the purpose of a voltage stabiliser.
UPS also helps to give longetivity to the equipment it is protecting, as it helps to cushion the damaging effects of erratic power conditions on the equipment it protects.
TYPES OF UPS
Basically, there are two broad types of UPS, Standby/offline UPS and online UPS. There are other types like line interactive, Delta conversion, Ferro-resonance and so on, but I will limit my discussion only to these two basic types common in homes and offices.
This type of UPS cannot guarantee data safety as it uses relay for switching. It runs constantly on mains (power supply) and switches to battery mode only when the voltage rises or falls below pre-determined value. Data may be lost during this short switching period. This type of UPS is available below 1KVA.
This type of UPS is used for equipment that are very sensitive to power fluctuations, such as servers, routers, switches and personal computers. For this type of UPS, no switching actually takes place since the batteries are always connected to the inverter. This type of UPS is recommended for data safety. Although the initial cost of this UPS may be higher than its offline counterpart, the maintenance cost is lower due to longer battery life.
Another advantage of this type of UPS is in its ability to provide electrical firewall between the incoming utility power and sensitive equipment. It can adapt to varying input frequency range such that the output frequency can be maintained within the acceptable window.
HINTS ON MAINTENANCE OF UPS
UPS is not an inverter; it is designed only to back up for a short duration of time, say 5 to 20 minutes on battery. Prolonged use may result in sudden shutdown of load and low lifespan of the battery.
UPS must be constantly connected to a supply source (PHCN, Generator or solar panel) and should not be allowed to operate on battery for an extended period of time. Doing so will shorten the lifespan of the batteries.
UPS must not be over-loaded. Each UPS has its capacity written on its name plate (either in VA, WATTS, KVA, KW e.t.c). Also each appliance to be connected to the UPS has its own power consumption or current rating written on it. Total capacity of these appliances added together must not exceed 80% of the rated capacity of the UPS. Over-loading can completely damage the UPS, or in the least throw off the entire load.
UPS must be completely powered up with the soft button before it can backup during power outage or fluctuations.
Ensure to shutdown the UPS when leaving home or closing for business. This will ensure that it does not run down on battery when there is power outage.
Ensure your UPS is serviced by an expert at least once in six months in an extremely dusty environment or annually in a less dusty environment.
Ensure that there is no loose connection on the UPS terminals. Loose connection is one of the primary causes burning of cables and in some cases fire outbreak. During servicing, tell the technician to check the terminals for you to ensure it is electrically sound and firm.
For industrial applications involving high capacity UPS, ensure that the technician to handle the installation provides adequate protection both.
COST EFFECTIVENESS OF USING INVERTER/SOLAR OVER GENERATOR
I was asking my friend a question this morning
The question was, how much does it cost to fuel your Generator?
His response was ₦1,500 (Nigerian Naira).
As a matter of fact, my friend has 2.9KVA Generator which he uses to power his house.
I interviewed him on how much he spends to fuel his Generator. Here is his response
₦1,500 fuel when ran for 4 hours per day lasts 4 days, meaning ₦1,500 lasts for an average of 16 Hours.
This means an average of ₦100 per hour.
If he were to use the Generator for 12 hours a day as I use my inverter (7pm to 7am), he would be spending a total of (₦1,200 X 7) = ₦8,400 in a week
In just a month, he would be expending ₦1,200 X 30 = ₦36,000 on fuel alone.
Now let’s get down to Inverter
An average Inverter battery under normal circumstance and with normal maintenance is designed to last an average lifespan of 4 to 5 years before replacement is expected, but to be conservative, I am using an average of 4 years for my calculation.
Hence in 4 years, my friend would be spending (₦438,000 per year X 4 years) = ₦1,752,000on fuel alone, apart from cost of Generator servicing and repairs and the initialcost of buying the Generator.
Now, with 1.5KVA Inverter, the total amount I will spend for complete installation is a lump sum of ₦322,000 for the 4 years that the batteries will last.
From these analytical calculations, it is obvious that the cost of running a Generator for just 8 to 9 months only has covered what it would require to install 1.5KVA Inverter with batteries that will last for 4 years before battery replacement. This does not include the cost of buying the Generator itself which is about.₦120,000
So with Inverter, I have saved a total cost of ₦1,430,000 (One Million, Four Hundred and Thirty Thousand Naira Only) overt the 4 year period.
Now, that is just the cost implication.
There are other benefits of Inverter that might not have considered, here are few of them:
(2) With Inverter, you can sleep throughout the night without interruptions brought by the need to turn off or to add fuel to the Generator.
(3) You don’t disturb yourself and neighbor with the noise of your Generator. Some neighborhood don’t even allow running a Generator overnight for security reasons. In such neighborhood, most residents are forced to endure blackout under extreme heat.
(4) You don’t contribute to environmental pollution caused by harmful carbon mono-oxide that is being released from the Generator exhaust.
(5) You don’t need to disturb yourself with turning ON and OFF of Generator every time power is interrupted by the public utility supply authority. Inverter automatically switches itself to battery mode and vice versa when there is power interruption/restoration.
(6) You don’t waste energy as you only take what you need from the battery based on the load, unlike the generator that burns fuel irrespective of whether any load is connected or not.
(7) You are immune to fuel scarcity. During fuel scarcity, you don’t need to spend your productive or rest hours queuing for fuel at the filling station.
These and other reasons are stated so that you can know how much you have been losing by not taking advantages that Inverter offers you.

How much energy does a solar panel produce?
While many factors affect the amount of energy a solar panel can produce, you can expect a typical single solar panel in the United States to generate about 2 kilowatt-hours (kWh) per day, saving an average of 0.36 on electricity costs per day.
Now, 0.36 doesn’t seem like a lot, but that’s just the energy savings for one panel over the course of one day. Installing a whole solar panel system, on the other hand, would save you more like 130 a month (or more!).
What determines how much electricity a solar panel will produce, and how can you determine the amount of one solar panel’s generation? Let’s find out.
See how much you can save by going solar
- Most residential solar panels today have a power output rating of between 370 watts and 400 watts.
- The average-sized solar panel will produce between 1.5 kilowatt-hours and 2.4 kWh of electricity per day.
- One solar panel generates enough electricity to power small appliances like a TV, lights, or device chargers.
- How much energy a solar panel produces depends on how much sunlight the panel gets, the panel’s construction, your roof’s characteristics, and even how old the panel is.
- Installing a whole solar panel system allows you to power your home with renewable energy, decrease reliance on your utility, and, most importantly, lower your electric bill.
How much electricity does a solar panel generate?
The average solar panel is able to output between 370 and 400 watts of power. This works out to a single solar panel producing about 2 kilowatt-hours (kWh) of electricity per day. That’s enough electricity to watch your TV nonstop for almost a full 24 hours.
The following table outlines how much electricity a 400-watt solar panel would produce under ideal conditions over the course of a day, a week, a month, and a year:
|Electricity production of 400-watt solar panel
How many solar panels do I need to power my house?
Let’s be honest, no one is installing just one solar panel on their roof. As mentioned above, one solar panel will produce roughly 2 kWh daily. On the other hand, the average U.S. home uses about 29 kWh of electricity daily. So, you’ll need a lot more than just one panel.
In fact, you’ll probably need at least 15 solar panels on your roof to generate enough electricity to cover your daily energy usage. That works out to about 6,000 watts of solar, or 6 kilowatts (kW). A 6 kW system will produce about 10,950 kWh per year. That’s enough electricity to cover the average household’s electricity usage and potentially eliminate a 135 electricity bill.
The actual number of solar panels you need will largely depend on how much energy you use throughout the year. But it will also depend on your panels’ environment and the panels themselves.
factors that affect the amount of electricity that solar panels produce
We want to be totally honest with you, most of the time, solar panels won’t produce the maximum amount of energy possible. Solar panel specifications, like power output ratings, are determined by testing the panels in a laboratory under Standard Test Conditions.
Your roof isn’t exactly a lab, and the conditions it’s under aren’t always going to be ideal for your solar panels. There are a number of things that will impact how much energy your solar panel is generating.
Amount of sunlight
The amount of sunlight that hits a solar panel is one of the biggest factors in how much electricity it will generate. The more sunlight available to the panel, the more electricity it can produce.
This means you’ll want to install solar panels on an unshaded portion of your roof. You don’t want overhanging tree branches or your chimney casting shadows on your panels. Even dust and debris can cause your panels’ production to drop, so it’s important to clean your solar panels once or twice a year.
It’s more than just if your panels are shaded or not. It also has to do with if where you live naturally gets a lot of sunlight. Scientists use “peak sun hours” to compare how much sunlight different places get. Solar panels will be able to generate more electricity in places that get more peak sun hours.
The following table lays out how much energy a 400-watt panel could produce in states that receive different amounts of sunlight, assuming all other conditions are the same:
|Number of peak sun hours
|Daily electricity production
You can hear more about how weather conditions impact solar panel production in this video from SolarReviews founder, Andy Sendy:
The panel itself also affects how much energy it can produce. Solar panels are made up of solar cells, which are what actually turn sunlight into electricity. Today, most solar panels use monocrystalline solar cells, AKA the most efficient silicon solar cell made today. If you used a polycrystalline solar panel, it wouldn’t be able to generate as much electricity as its monocrystalline counterpart.
It’s not just about the material the solar cells are made out of – how much electricity a panel produces is also impacted by how many cells there are and how those cells are shaped! Solar panels typically come in two sizes: 60-cell solar panels for homes and 72-cell panels for larger commercial installations.
72-cell panels have more solar cells, so they’re able to generate more electricity, but they’re too large to use on many residential roofs. However, a lot of solar panel manufacturers today are starting to make 66-cell solar panels that are still practical for home solar, but the extra six cells mean the panels can produce more energy!
Manufacturers are also making more half-cut solar panels, where the solar cells are cut in half with a laser before being put into the panel. This increases the efficiency of the panel so it can generate more electricity. Half-cut panels are also wired differently than traditional panels, so shading has less of an impact on how much energy is generated.
Bifacial solar panels: Bifacial solar panels are able to generate electricity from light that hits both the front and the back of the panel. When sunlight hits the ground and bounces back up, bifacial panels can capture that reflected light and use it to make more electricity. These aren’t particularly useful for homeowners with rooftop solar, but they can be a great option for ground-mounted systems.
The truth is, not all roofs are good for solar. The characteristics of your roof are a major player in how much energy solar panels can produce for your home.
The number one thing you need to consider is the direction of your roof. The best direction for solar panels to face is south, so you’ll want to have a south-facing roof for maximum energy production. This doesn’t mean you can’t install solar panels if your roof faces a different direction. The panels will just generate less electricity because they get less sunlight.
The following table outlines how much electricity a solar panel will generate facing different directions if all other factors are the same:
|Solar panel direction
Assumes 400-watt solar panel and 5 peak sun hours
The panel’s age
The panel’s age is often forgotten, but it’s important to remember that your solar panels won’t produce the same amount of energy for their whole life. As solar panels age, they lose a bit of their ability to generate power. You can think of it as any other electronic you have. your laptop probably doesn’t work as well as it did the day you bought it.
Solar panels, on average, degrade at a rate of about 0.5% per year. So, by the end of a panel’s typical 25-year warranty period, they usually operate at about 85% of what it was initially. Don’t worry – your solar panels will still generate enough electricity to help lower your utility bills.
See how much it would cost to power your home with solar panels
How to determine how much electricity a solar panel can produce
So, now that we’ve covered what impacts a solar panel’s ability to produce electricity, we can get into the good stuff. figuring out how much power solar panels will produce for your home.
We’ve already established that there are a number of factors that are going to impact how your solar panels generate electricity. So for the sake of simplicity, we’re only going to take a couple of things into account for the below example, including:
All you need to do is multiply the wattage of your panel by the number of daily peak sun hours. A homeowner in Florida who installs a 400-watt solar panel can expect about four peak sun hours in a day. That means this panel would produce 1,600 watt-hours of electricity per day. Electricity is usually measured in kilowatt-hours, so you simply divide your 1,600 watt-hours by 1,000 to get 1.6 kilowatt-hours.
400 watts x 4 peak sun hours = 1,600 watt-hours per day 1,600 watt-hours /1,000 = 1.6 kWh per day 1.6 kWh x 30 days = 48 kWh per month 1.3 kWh x 365 days = 584 kWh per year
Bear in mind, this is a really simplified way of calculating how much electricity a solar panel produces. The actual amount will fluctuate day by day, even hour by hour, based on all the factors mentioned earlier. Use our solar panel calculator to get a more accurate view of how much electricity you can expect solar to produce on your roof.

|Candian Solar HiKu6
|Qcells Q.PEAK DUO BLK ML-G10
|Jinko Eagle 66TR G4
Estimated production of a single panel assuming 5 peak sun hours at STC.
Keep in mind, high-wattage panels tend to come with high price tags, too. This means you may have to pay more upfront for your system, but you’ll need fewer panels to meet your energy needs.
Power your whole home with solar to save money
Now you know how much solar electricity you can expect one solar panel to produce and how much a whole system can, too.
But the best part is that installing solar does way more than just let you power your home with renewable energy. it helps you save money. By using the electricity generated by solar panels on your roof, you don’t have to take electricity from your utility, which means they don’t have to charge you.
Most of the time, you can install enough solar panels to cover all of your electricity costs. In fact, that 6 kW solar system we discussed earlier could save the average American homeowner around 130 a month!
But of course, this is just an estimate. Just like with how much electricity a panel produces, how much solar panels can save you depends on many factors. The easiest way to determine how much solar panels can save you is by using our solar panel savings calculator below. Not only will you get a free solar savings estimate, but you can also choose to get in contact with vetted local solar installers to start getting real solar quotes for your specific home.
How Many Batteries for 1000 Watt Solar System?
Nowadays, various power variations are available for the batteries of the solar system. But in 1883, Charles Fritts from the United States made the first solar cell from selenium. At that time, no one thought that this technology would be so successful in the future. However, more and more people are turning towards solar technology. If you are planning to do so, this is a decision for life. You will learn today about how many batteries for 1000 watt solar system are accurate, how many batteries for 2kw solar system are required, and how many solar panels for 1000 watts are apt.
What are Solar Batteries?
Solar batteries are devices that store the excess electricity generated by your solar panels is the battery of your solar panels. This stored power is used by the solar system to power your home, lightning, or any other appliances that are connected to it.
How Many Batteries for 1000 Watt Solar System are Required?
A 1000-watt solar panel system is the most common range of solar power systems available in the market. Solar panel systems are dependent on the sun, but if you want to run them on cloudy days, you will need batteries to power them. Now your next question must be how many batteries for 1000 watt solar system are required? Well, it depends. A single 200-ah lead battery is capable of running a 1000-watt solar system for 1 hour, and larger batteries can even run such systems for longer periods. If your solar panel has the right voltage, even a 24V battery can be used. If fully discharged, a 12V 100ah lithium battery can also supply 2400 watts (but only 1200 watts can be tapped because of 50% depth discharge). These are few-watt equivalents for various 12V batteries.
- 100ah 1200
- 200ah 2400
- 300ah 3600
- 350ah 4200
- 400ah 4800
- 500ah 6000
In a solar system, any of these batteries can supply 1000 watts. The difference is just in the duration of supply. For example, a 300-ah battery with a 50% DOD has 1800 usable watts which is good an hour and a half, or maybe an hour and 45 minutes. On the other hand, if you use two 250-ah batteries that is 500ah or 6000 watts. Even with only 3000 watts available, the battery can carry a 1000-watt load for 3 hours.

However, the number varies depending on the usage and time period for which you need a solar power system.
What is an Inverter and Charge Controller?
For a solar power system to work efficiently, only panels or batteries are not sufficient. You need an inverter to manage the power. A charge controller regulates the electricity flow from the Photo Voltaic (PV) generator or Inverter to the battery. It regulates the voltage and current supplied by the generator or inverter. It prevents over-charging and over-discharging of the battery. Therefore, it is also known as Battery Charge Controller (BCC).
Efficiency Ratings of Inverters

What size solar inverter do I need?
Solar inverters are one of the most important components of a solar panel system. They’re responsible for converting direct current (DC) electricity from your solar panels to alternating current (AC) electricity to power your appliances. When it comes to designing your solar panel system, the size of your inverter will play an important role in overall electricity production. In this article, we’ll discuss what impacts solar inverter sizing.
How to determine inverter size
Solar inverters come in all different sizes, big and small. Similar to solar panels, the size of an inverter can be rated in watts (W). When it comes to solar inverter sizing, installers will take three primary factors into account: the size of your solar array, your geography, and site-specific conditions.
Size of your solar array
The size of your solar array is the most important factor in determining the appropriate size for your solar inverter. Because your solar inverter converts DC electricity coming from the array, it needs to have the capacity to handle all the power the array produces.
As a general rule of thumb, the size of your inverter should be similar to the DC rating of your solar panel system; if you are installing a 6 kilowatt (kW) system, you can expect the proposed inverter to be around 6000 W, plus or minus a small percentage.
Inverter manufacturers typically list sizing guidelines for the array capacity their inverters can be paired with on their product spec sheets. If the size of the solar array paired with their inverter is outside of the stated guidelines, manufacturers may void their warranty offering.
Geography also plays an important role in sizing your solar inverter due to its impact on the production of your solar panel system. Properties in Arizona have higher solar irradiances (i.e. larger amounts of solar radiation) than properties in Vermont; as such, a rooftop 6 kilowatt (kW) system in Arizona should produce more power than a similarly sized system further north.
Because these two systems will produce different amounts of DC electricity at a given point in time, the inverters needed to handle that electricity load can also be different sizes. In areas with more sunshine and moderate temperatures, inverters will likely be sized closer to the overall wattage the solar array so it can handle close to the maximum power output of the array at any given point. Alternatively, if your solar array experiences lower amounts of solar radiation or high temperatures that decrease panel efficiency, it’s less likely to produce that maximum power output defined by the DC rating under standard testing conditions (STC). In these scenarios, a smaller, undersized inverter may get the job done.
The site and design specifics of your solar array will impact the size of your solar inverter. Similar to geography, the tilt and azimuth your solar array is installed at will affect how much electricity the system can produce. Environmental factors (such as shading, dust, etc.) will similarly play a large role in how much sunshine reaches the array.
Solar installers will account for these considerations, equipment efficiencies, and more when estimating the overall production of your solar panel system. All will contribute to the overall derating factor of your system, which is used to help determine what your solar panel system will produce in a real-life scenario (as opposed to the STC specs determined in a lab.) Solar panel systems that experience more shade, are at a sub-optimal tilt, or facing east rather than due south have higher derating factors than systems on sunny, south-facing roofs.
Solar panel systems with higher derating factors will not hit their maximum energy output and as such can afford smaller inverter capacities relative to the size of the array.
Calculations for solar inverter sizing
The size of your solar inverter can be larger or smaller than the DC rating of your solar array, to a certain extent. The array-to-inverter ratio of a solar panel system is the DC rating of your solar array divided by the maximum AC output of your inverter. For example, if your array is 6 kW with a 6000 W inverter, the array-to-inverter ratio is 1. If you install the same sized array with a 5000 inverter, the ratio is 1.2. The majority of installations will have a ratio between 1.15 to 1.25; inverter manufacturers and solar system designers typically do not recommend a ratio higher than 1.55.
Below are some examples of solar inverter products and their maximum DC power output recommendation:
|Sunny Boy 5.0-US
A higher array-to-inverter ratio may work for your system if your solar panels will not produce at their maximum power output due to the factors mentioned above. The benefit of oversizing your solar array relative to the inverter capacity is that lower-wattage inverters will be less expensive than their larger counterparts. But it’s not advisable to oversize your array too much as it can cause clipping. Clipping occurs when your solar panels are producing too much DC for the inverter to handle at a given point in time. When this happens, the inverter will limit the amount of energy it’s converting, resulting in power losses from your solar panel system.
On the other hand, you don’t want to install a solar inverter that’s too big (i.e. has a lower array-to-inverter ratio) because your inverter is going to be most efficient if it’s running close to its overall capacity. If the inverter is too large compared to the array, it will not produce the desired amount of electricity.
What about microinverters?
With microinverters. the conversion from DC electricity to AC electricity occurs at each individual panel. Microinverters are smaller than large central inverters devoted to handling power for an entire system. As such, the size of a microinverter corresponds to the energy output of the solar panel it’s converting power for rather than the DC rating of the entire system.
Similar to central inverters, manufacturers of microinverters will list guidelines as to the maximum DC rating a panel should have if tied to their microinverter product. If you connect a higher wattage panel than the microinverter specs indicate, then clipping will occur.

Solar panels kwa AC: 1,2,3,4 5T: Solar panels kwa AC: Solar panels kwa AC: Solar panels for AC: Solar panels for AC: Solar panels for AC: Solar panels for AC: Solar panels for AC: Solar panels for AC: Solar panels for AC: Solar panels for AC: Solar panels for AC: Maswali yanayohusiana na paneli za jua yanakuwa yenye kusisimua zaidi na zaidi. Kwa sababu ya maswali haya, watu wengi wana wasiwasi juu ya jinsi paneli nyingi za jua zinahitajika kuendesha mzigo wao mzito. Kwa kawaida, sehemu kubwa ya nyumba ni kiyoyozi. "Kama unavyojua, kuna suala la ""Ni nini kinachohitajika ili kuendesha AC?"" - kwa kila tani ya uwezo, AC hutumia kitengo kimoja cha nguvu kwa saa, na kuendesha sawa kwa masaa 8 hadi 20 kila siku na paneli za jua, unahitaji paneli za jua za 5 hadi 12 za 330W na inverter ya gridi na kipimo cha wavu." Kwa mfano, unaweza kutumia mimea ya jua ya 1.6 kW na 4 kW, ambayo ni pamoja na umeme wa umeme wa umeme wa umeme wa umeme wa umeme wa umeme wa umeme wa umeme wa umeme wa umeme. Kwa kuwa betri bado ni ghali na zinahitaji matengenezo ya mara kwa mara na pia kubadilishwa. "Hakuna haja ya kutumia umeme wa jua kama ""msaada wa betri"" (kwa mfano, umeme wa jua unaoweza kuondolewa kwenye gridi ya umeme) kama vile umeme wa umeme unaoweza kuondolewa kwenye gridi." Kituo cha umeme wa jua kilichounganishwa na kamba ni nini? Jua linaweza kuangaza kwa masaa 5 hadi 8 tu, lakini mahitaji yetu ya umeme ni kwa masaa 24. Ili kuweza kutumia nishati ya jua kwa masaa 24 ya mahitaji, tunahitaji kuwa na kituo cha nishati ya jua kikubwa vya kutosha kuzalisha nishati ya ziada zaidi ya mahitaji yetu ya mchana na njia ya kuhifadhi nishati hii ya ziada kwa matumizi ya usiku. Ili kuhifadhi nishati hii ya ziada, betri inaweza kuwa chaguo, lakini kuhifadhi umeme katika betri bado ni ghali. Uaminifu wa nishati ya jua unategemea kabisa hali ya hewa, ikituongoza kwenye mapumziko ya umeme siku fulani za mwaka. Inverters za kamba (pia huitwa inverters kwenye gridi au gridi-kuunganishwa) zimetengenezwa, ambazo hubadilisha nguvu ya DC (mzunguko wa moja kwa moja) inayotokana na paneli za jua kuwa nguvu ya AC (mzunguko wa mbadala) kwa usawa na nguvu ya gridi. Faida ya kusawazisha nishati ya jua na gridi ni kwamba ikiwa tunazalisha nishati zaidi ya mahitaji yetu ya mchana, nishati hii ya ziada inaweza kubadilisha maoni kwa gridi. Kwa maneno sahili, nishati ya ziada kutoka kwa mitambo ya nishati ya jua itasafirishwa kwenye gridi. Na nguvu hii ya kuuza nje itatozwa kutoka kwa nguvu utakayotumia usiku. Kwa hiyo ukanda wako utakuwa betri kubwa kwa ajili yenu na huna hata haja ya kulipa kwa ajili yake. Jua linapotua, kiwanda cha umeme wa jua hakitakuwa na uwezo wa kutokeza umeme. Kwa hiyo tunahitaji kutumia nguvu kutoka kwa gridi na kiasi cha nguvu tunachotumia usiku kitalipwa na nguvu tuliyoingiza kwenye gridi wakati wa mchana. Mchoro hapo juu inaonyesha uhusiano wa kawaida wa Grid-tied [on-grid] Sasa, kuondoa nguvu nje ya gridi kutoka nguvu kuingizwa kutoka gridi, unahitaji <unk>Net-metering<unk>. Ikiwa hakuna umeme wa umeme wa umeme katika eneo lako, unaweza kutumia umeme wa umeme wa umeme wa umeme wa umeme wa umeme wa umeme wa umeme. Mimi sana kupendekeza kusoma blogu yetu juu ya <unk>Solar bila wavu-metering<unk>. Kwa mfano, kwa kila tani ya AC, tunatumia nguvu ya 1 unit kwa saa, na kwa kila tani ya AC, tunatumia nguvu ya 1 unit kwa saa, na kwa kila tani ya AC, tunatumia nguvu ya 16 unit kwa saa. Kwa mfano, unaweza kutumia nguvu ya AC ya kiwango cha juu (tani 1, toni 1, 5, 2, 3, 4, 5, 5, 5) kwa masaa tofauti ya kila siku. Angalia meza hapa chini inayoonyesha sawa. Kama unaweza kuona kutoka kwa meza hapo juu, kuendesha AC ni ghali sana na kuanzisha kituo cha nishati ya jua kuendesha itakuwa ghali pia. Ikiwa paneli za jua ziko katika bajeti yako au la, ninapendekeza sana usome blogi yetu juu ya vidokezo 15 vya gharama nafuu vya kupunguza matumizi ya nguvu ya AC. Ukubwa wa paneli za jua za kuendesha uzalishaji wa umeme wa AC kutoka kwa paneli za jua hutegemea wakati wa jua, kiwango cha uchafuzi, eneo lisilo na kivuli na pembe ya kuelekeza. Kwa kuzingatia eneo lisilo na kivuli, kiwango cha chini cha uchafuzi wa hewa, na pembe ya kulia ya kuelekeza, paneli za jua za 1 kW (330W x 3) zitazalisha vitengo vya umeme vya 5-6 katika masaa 7 hadi 8 ya jua. Ili kuendesha tani moja ya AC kwa masaa 8, unahitaji paneli za jua zinazozalisha (1 x 8 = 8 vitengo) vitengo 8 vya nguvu [ambayo ni 8kWh] kwa siku. Kwa hiyo, ukubwa wa kiwanda cha umeme wa jua cha belt-tie kinachohitajika kuzalisha vitengo 40 vya nguvu (kW) ni sawa na 8kW, na paneli za jua zinakuja katika ukubwa tofauti kama vile 330W, 325W, 360W, na vinginevyo, kwa hivyo idadi ya paneli za jua zinazohitajika zinaweza kuwa tofauti kwa viwango tofauti vya paneli za jua. Kwa kuwa paneli za jua za 330W zinatumiwa sana leo, tunaweza kuhitimisha kwamba paneli za jua za 330W zinahitajika kuendesha tani moja ya AC kwa masaa 8 kila siku. Kwa mfano, unaweza kuhesabu ukubwa wa gridi-kuunganishwa solar power plant zinahitajika kuendesha uwezo tofauti ya AC kwa vipindi tofauti vya muda. Angalia meza hapa chini kuonyesha sawa kwa urahisi wa uelewa wako. Kwa mfano, kwa ajili ya kuendesha 1T AC kwa masaa 8 kwa siku, unahitaji angalau 5W ya vifaa vya jua, na kwa ajili ya kuendesha 1T AC kwa masaa 12 kwa siku, unahitaji 7W ya vifaa vya jua. Kwa mfano, kwa ajili ya kuendesha 1.5-ton AC kwa saa 8 kwa siku, unahitaji angalau namba 7, 325 Watt solar panels, na kwa ajili ya kuendesha hiyo kwa saa 12 kwa siku, unahitaji namba 11 ya 325 Watt solar panels. Kwa mfano, kwa ajili ya kuendesha AC ya tani 2 kwa masaa 8 kwa siku, unahitaji angalau namba 10, ndege za jua za Watt 325 na kwa ajili ya kuendesha AC hiyo kwa masaa 12 kwa siku, unahitaji namba 15 za paneli za jua za Watt 325 Matatizo yote ya Inverter na Suluhisho.

Shrego ProBTech Online.... <unk>Kukusaidia Kukuza Bidhaa Yetu<unk> Kwanza, hebu tufafanue Inverter Ni nini Inverter? Inverter ni aina ya UPS ambayo ina muda mrefu wa kuhifadhi. Ina chanzo cha pembejeo kushikamana na mains kutoka chanzo cha huduma ya umma, au jenereta. AC inageuzwa kuwa DC kwa njia ya rectifier kwenye mzunguko wa Inverter ili kuchaji betri. Bateria ya DC ya kuchajiwa inageuzwa tena kuwa AC (Alternating Voltage) kupitia transformer ya hatua ya juu, ambayo inasaidia mzigo (vifaa) wakati wa kukatika kwa umeme, kwa hivyo jina la INVERTER. Kuna Inverters nyingine pia kwamba si kuingiza matumizi ya transformer kutengwa, wao ni aitwaye Transformerless Inverters. Mbali na runtime, kuna vipengele vingine kwamba kutofautisha Inverter kutoka UPS. Kwanza, muda wa kubadili kati ya UPS na baadhi Inverters inatofautiana. Wakati wa kubadili kwa UPS ni katika safu ya 0.5 ms hadi 5 ms, wakati kwa Inverter, inaweza kuanzia 20 ms hadi 500 ms. Hii muda mkubwa lag inaweza kuonekana kama kukatika nguvu na vifaa nyeti. Wakati UPS ni kujengwa hasa kwa muda mfupi data ulinzi wakati kuna kukatika nguvu, kwa sababu inaweza kufanya voltage udhibiti katika pato, baadhi ya chini ya daraja offline Inverters ni kwa upande mwingine ni lengo hasa kwa ajili ya chelezo tu, lakini si vifaa kwa ajili ya mpito laini kati ya kukatika nguvu. Kwa maneno mengine, hawana vifaa vya mzunguko usio na usumbufu. Wao kutumia baadhi ya mfumo wa relay kwa ajili ya kubadili. Inverters kama hizo haziwezi kuhakikisha ulinzi wa data hasa wakati wa fluctuation nguvu au wakati nguvu ni nje ya mbalimbali. Ni tu taka-katika- taka nje maana, chochote voltage inakuja ni nini inatoa nje katika pato. Kama voltage ya kuingia ni duni, voltage ya pato pia itakuwa duni. Kwa kuwa hakuna kubadilisha halisi katika UPS ya mtandaoni, inashauriwa kuunganisha vifaa nyeti sana, kama vile seva, switches, kompyuta na vifaa vingine vya mawasiliano kwa UPS. Inverter ni mfumo wa umeme wa umeme unaoendeshwa na betri za nje, na kwa sababu ya ukubwa wake, inaweza kutumika kama mfumo wa umeme wa umeme. Inverter ina uwezo wa kuchaji betri kubwa kuliko UPS, na inaweka kiwango cha muda wa kuchaji kwa betri ambazo zinaweza kutumika. Kwa muhtasari, UPS zote zina mzunguko wa inverter ndani yao, lakini sio Inverters zote hufanya udhibiti wa voltage ambayo inahakikisha nguvu iliyodhibitiwa wakati wa kukatika, kama UPS ingefanya. Inverters inaweza kuhifadhi kwa masaa au siku, UPS inaweza tu kudumu kwa dakika au saa chache, muundo wao kuu ni kuhifadhi nguvu kwa muda na kuzuia kukatika tu mpaka chanzo kikuu cha nguvu ni kurejeshwa. Inverters ya kawaida ni pamoja na matatizo ya kawaida ya inverter na matatizo ya kawaida ya kuonekana kwa makosa ya kawaida, ambayo yanaweza kuonekana katika vichwa vya habari.

Kwa nini betri inaweza kushindwa kwa urahisi (Kwa Inverter) Ufanisi wa gharama ya kutumia Inverter (Solar) juu ya Jenereta (Ufanyakazi wetu) Sasa, hebu tuingie katika maelezo na nini cha kufanya ili kutatua kila moja ya matatizo haya moja baada ya nyingine. Inverter haijajaza: Kuna sababu nyingi kwa nini Inverter haijajaza, hakuna usambazaji wa umeme: Unapogundua kuwa Inverter haijajaza, jambo la kwanza kufanya ni: (i) Angalia chanzo cha umeme ili kuhakikisha kuwa umeme unapatikana. Hakikisha nguvu inapatikana kutoka chanzo cha matumizi ya umma ya Jenereta. Ikiwa inapatikana, angalia breaker kati ya chanzo cha umeme na Inverter (ii) Angalia fuse katika plug, ambapo plug ni kutumika kuunganisha Inverter kwa chanzo cha umeme na kubadilisha kama blown off (lakini kuwa na uhakika wa kugundua nini kusababisha fuse kuvunja na kurekebisha pale inahitajika). (iii) Hakikisha kwamba soketi ya pembejeo na kuziba ni sawa, na ambapo muunganisho wa pembejeo ni kupitia kiunganishi, hakikisha hakuna kuachana au kuunganishwa kwa kebo ya pembejeo. (iv) Angalia mwendelezo wa cable ya pembejeo, kuwa na uhakika cable kusambaza nguvu kwa Inverter si kuvunjwa. - Bad input Voltage au mzunguko: Kama input Voltage au mzunguko ni juu sana au chini sana kwa thamani ya kuweka ya Inverter au kuna nguvu fluctuation, Inverter kuchelewesha kukubali usambazaji. Mzunguko wa voltage inaweza kuwa kurekebishwa na Voltage Regulator imewekwa katika pembejeo ya Inverter, lakini mzunguko lazima kuwa kurekebishwa na Umma Utility Supply Authority au juu ya Generator. Nambari sahihi ya Voltage na Frequency na dirisha la ruzuku inategemea kiwango cha kila nchi. Unaweza kuweka Inverter kukubali pana voltage / Frequency dirisha kama vifaa na chaguo kama hilo. - Blown fuse: Inverter pia inaweza si malipo kama fuse pembejeo ni blown au kuvunja safari kutokana na kosa. Kwa kuwa breaker haiwezi tu trip au fuse blown bila sababu, sababu ya hii lazima kuthibitishwa kabla ya breaker ni reset au fuse kubadilishwa. Katika kubadilisha fuse, fuse lazima kubadilishwa na kiwango sawa kabisa, vinginevyo, uharibifu mkubwa utafanywa kwa bodi katika kesi ya kosa jingine. - Connection makosa: Kama mstari na neutral au ardhi nyaya ni interchanged, Inverter inaweza si malipo lakini kuja na ujumbe wa kosa juu ya kuonyesha. Kuunganisha cable ya umeme na inverter ya umeme na kuunganisha Neutral na inverter ya umeme. Pia kuhakikisha kwamba polarity betri ni sahihi. Ikiwa betri haijaunganishwa au breki ya DC ya betri haijawasha, Inverter haitachaji. Kuunganisha makosa inaweza kusababisha uharibifu mkubwa kwa Inverter, kwa hiyo kuhakikisha kwamba wafanyakazi wa kiufundi waliohitimu ni kuajiriwa kushughulikia Inverter yako ufungaji.

Unaweza pia kuwasiliana na Shrego ProBTech kwa msaada kama unataka kuokoa gharama. - Battery kamili: Katika baadhi Inverters wakati betri ni malipo, Charge kiashiria blinks lakini huacha blinking na inabaki imara wakati betri ni kamili au karibu kamili, baadhi ya wateja interpret hii kumaanisha kwamba betri si malipo. Wakati betri ni kamili, kiashiria betri huacha blinking na inabaki imara, mpaka kuna kushuka katika betri ya voltage nominal. Ili kuthibitisha kama Inverter ni kuchaji, kuzima pembejeo ya Inverter na drain betri kidogo, kusema kwa dakika 10 au zaidi kisha kurudi, nguvu kwa pembejeo, kiashiria lazima kuanza blinking tena kwa dakika chache kabla ya kuacha tena. Battery ni sehemu kuu ya inverter ambayo inahitaji kuchaguliwa kwa uangalifu kutoka duka la kuaminika, kwa kuwa kubadilisha ni gharama kubwa sana na mafanikio ya ukarabati hayawezi kuhakikisha. Wakati betri inashindwa, moja au zaidi ya yafuatayo inaweza kuwa na jukumu: (i) Battery Under Charged (Batri chini ya malipo) au Over Charged (Batri ya juu) - kila betri ina mzunguko wake wa malipo na kutolewa. Betri ambayo ni kuendelea chini ya malipo au juu ya malipo haiwezi kudumisha maisha yake ya rating. Inverters za kisasa za akili zina sensorer ya kukata ya malipo ya juu au ya kufuta ambayo inahakikisha kwamba betri hazijajazwa au kutolewa. Hata hivyo, wengi wa bei nafuu (sub-kiwango) Inverters katika soko si vifaa na kifaa hiki akili, ambayo husababisha betri kwa kuchemsha wakati overcharged au kusababisha suffocation kuanzisha wakati betri ni daima over-discharged na si daima kuhifadhiwa katika malipo kamili. Kwa betri kutumika maisha yao ya kutajwa kwa mafanikio bila kushindwa mapema, lazima kudumishwa kubeba wakati wote baada ya matumizi. Jambo jingine la kuzingatia ni kwamba, betri hazipaswi kutolewa kupita kiasi. Kwa kweli, betri hazitarajiwa kutolewa chini ya 0.5V kwa kila seli. Kwa betri ya 12V, voltage ya chini ya kuondoa betri lazima iwe karibu 10.8V (kwa betri za kawaida). Mara baada ya chini ya hii, wengi Inverters akili itaanza beep kuonya kwamba betri ni chini na baada ya muda fulani shuts mwenyewe chini kabisa ili kuzuia uharibifu wa betri. Katika hatua hii, betri lazima kujazwa upya kikamilifu kabla ya matumizi, hata kama mashine kushindwa kuzima yenyewe. Watumiaji wengi wa betri wanalalamika juu ya kushindwa mapema kwa betri kwa sababu hawajui au kufuata maagizo haya rahisi ya matengenezo. Kwa kuwa si wote Inverters kwamba ni vifaa kwa shutdown au kuzuia juu ya kutolewa, ni vyema kutafuta maoni ya wafanyakazi wa kiufundi kabla ya ununuzi kwa Inverter; vinginevyo kukosa wakati wa betri itakuwa suala la mara kwa mara. Battery Charges: Ikiwa betri inaonyesha malipo kamili mapema sana, inamaanisha inafikia malipo yake kamili mapema kuliko kawaida, ambayo kwa hivyo huamua kiwango cha kutolewa, inaweza kuwa ishara ya kwanza kwamba betri inakuwa dhaifu. Betri yenye nguvu huchukua muda mrefu zaidi kuchaji kabisa na pia muda mrefu zaidi kufuta. Hata hivyo, katika safu ya betri ambayo inahusisha betri mbili au zaidi zilizounganishwa pamoja, kushindwa kwa betri moja katika kamba inaweza kuathiri utendaji wa betri nyingine katika safu. Nguvu ya betri zote katika kamba huamuliwa na uwezo wa dhaifu zaidi kati yao katika safu. Hii pia inaelezea kwa nini betri dhaifu na nguvu haipaswi kuunganishwa katika safu ya betri. Hii itaelezwa zaidi chini ya matengenezo ya betri. Jambo jingine muhimu la kuzingatia ni wakati betri discharges haraka lakini inachukua muda mrefu zaidi ya kuwa kikamilifu kushtakiwa. Katika kesi hii, unahitaji kutathmini jumla ya mzigo kushikamana na Inverter kupata kama kuna siri mzigo mzito draining betri. Ikiwa betri inachukua muda mrefu kujaza lakini inatoa haraka kuliko inatarajiwa, inaweza kumaanisha kuwa kuna mzigo mwingi sana kutoka kwa betri. Weka mizigo mizito na uangalie tofauti yoyote. Battery voltage ya chini: wakati voltage ya betri inakuwa chini sana, chini ya voltage ya kawaida, basi ni wakati wa kubadilisha. Moja ya dalili ambayo itaonekana ni kwamba betri discharges haraka kuliko kawaida na pia kukamilisha ni mchakato wa malipo mapema kuliko kawaida. Wakati betri inaonyesha malipo kamili ndani ya dakika chache za kuchaji, ni wakati wa kupiga simu kwa fundi wa betri ili kutathmini kiwango cha voltage au kiwango cha electrolyte, katika kesi ya betri ya bomba. Kwa seli za unyevu, kiwango cha electrolyte lazima kikaguliwa kila baada ya miezi mitatu na lazima kiwe juu ya kiwango cha seli. Hakuna maji mengine isipokuwa maji Distilled lazima kutumika kujaza tena seli, vinginevyo kutu ya seli na kwa hiyo kushindwa itasababisha. Bidhaa za kisasa za betri za tubular zimetengenezwa na kiashiria cha float ambacho hupima kiwango cha electrolyte kwenye kila seli, wakati electrolyte inapoanguka chini ya kiwango cha alama kwenye kiashiria cha float, ni wakati wa kuongeza electrolyte, seli kavu ni bure ya matengenezo, kwa hivyo wote wanahitaji ni kuendeshwa chini ya joto la baridi na kuwa daima katika hali ya malipo. Tatizo jingine ambalo linaweza kusababisha betri kuwa na voltage ya chini ni wakati betri imebaki katika hali ya kutolewa kwa kina kwa muda mrefu bila kuchaji, inaendeleza kile kinachoitwa suffocation ambayo inaweza kuwa haiwezi kubadilishwa, na inaweza kuwa haiwezekani kuamsha betri kama hiyo tena. Batri kavu hupoteza 2% ya voltage yake kila siku 30 ikiwa imeachwa katika hali ya kutolewa, wakati seli ya unyevu hujifungua hadi 10-15% kila mwezi, kwa hivyo betri lazima ichajwe kabisa ikiwa itaachwa bila kutumika kwa muda mrefu. Maisha ya rafu ya betri ni fupi sana, kwa hivyo haipendekezi kununua betri na kuhifadhi kwa muda mrefu ikiwa haitumiki. Ikiwa bettrie haitatumika kwa muda mrefu, inashauriwa kuchaji baada ya kila miezi mitatu na kuhifadhiwa mahali baridi. Joto husaidia kujitoa. Polarity ya betri: Ugeuzaji wa polarity ya betri unaweza kuharibu inverter, haswa ikiwa haijalindwa vya kutosha. Uwe makini kuhakikisha kwamba terminal chanya ya Inverter cable ni kumalizika juu ya terminal chanya ya betri na ditto kwa ajili ya Negative (-) terminals. Pia kwa ajili ya betri katika mfululizo au sambamba, polarities lazima si kugeuzwa. Ni daima inashauriwa na salama kuruhusu Mhandisi kushughulikia kila ufungaji betri. (v) Corroded Battery Terminal. Uharibifu wa terminal ya betri ni moja ya sababu za kuchaji vibaya kwa betri, kwani vifaa vilivyoharibika huunda filamu nyembamba ya insulation kati ya terminal ya betri na nyaya za kuunganisha, na hivyo kupunguza mtiririko wa sasa wa betri kutoka kwa Inverter. Ili kupunguza athari hii, unaweza kutumia jelly petroleum juu ya terminals betri baada ya scrapping mbali dutu corrosive au mara moja baada ya ufungaji betri. (vi) Swollen/Hot Battery. Hii ni hali ambapo betri hupata kuvimba au bulges nje kama matokeo ya kushindwa kwa betri. Betri kama hiyo inapaswa kutengwa kutoka kwa safu na kubadilishwa mara moja. Wakati betri ni kuchaji, kujaribu na kuhisi joto kutoka casing ya betri, kama Inverter si vifaa na sensor joto betri. Kama betri anapata unnecessarily moto, tafadhali, wita fundi mara moja. Betri inayopaa joto wakati wa kuchaji inaweza kulipuka, na kusababisha moto wa umeme. (vii) Vipande vya betri vilivyo huru. Kama terminals betri ni huru, upinzani wa juu itakuwa kujengwa karibu terminal ambayo kuzuia au kupunguza mtiririko wa malipo sasa kwa betri. Hii inaweza kusababisha arching (sparking) karibu terminal na katika kesi kali inaweza kusababisha moto. Hakikisha wote betri terminals ni imara. (viii) Battery Electrolyte kavu nje. Tubular au mvua seli betri, tofauti na kavu seli (matengenezo-free) betri inahitaji matengenezo ya mara kwa mara. Kiwango cha electrolyte lazima kufuatiliwa kwa karibu na haipaswi kuruhusiwa kukauka, vinginevyo, uharibifu wa kudumu unaweza kufanywa kwa seli za betri na kwa hivyo kushindwa kwa betri. (i) Loading juu ya uwezo wa kiwango Inverter. Kimsingi, wengi wa chini daraja ya ndani au viwanda Inverters ni iliyoundwa kwa ajili ya mizigo nyepesi- kama vile taa, vifaa vya elektroniki, na shabiki. Vifaa vya nguvu nyingi, kama vile friji, vifaa vya joto, oveni, air conditioners, motors za umeme na mashine za kusukuma hazifai kwa inverter za daraja la chini. Mbali na baadhi ya vifaa hivi kuvuta nguvu sana sasa kutoka betri na kusababisha ni kukimbia chini haraka, kuanza zao sasa inaweza kuwa mzigo juu ya inverter, kusababisha ni kuzima chini ya hali ya mzigo wa juu au hata kuchoma bodi ya mashine. Wakati wa kuhesabu mzigo wa kuunganishwa kwa Inverter, jumla ya matarajio (maximum mahitaji) mzigo lazima si kuzidi rating ya Inverter. Inverters lazima kuwa na kiwango cha juu zaidi ya mahitaji ya juu ya mzigo, kama 20% ya juu. Wakati wa kuhesabu mzigo wa jumla, ambayo ni jumla ya jumla ya watts za kila kifaa cha kuunganishwa na inverter, lazima kuzingatia tofauti kati ya kiwango cha watts cha vifaa vya kawaida kilichoandikwa kwenye bamba la jina na kiwango cha KVA ya inverter. Kilowatt ni sawa na KVA. Thamani ya ufanisi na nguvu sababu ya Inverter lazima kuwa nzuri. Kwa kuwa kuna tofauti kati ya kilowatt (KW) na kilowatt (VA), na vifaa vingi vimeorodheshwa katika kW, wakati inverter nyingi zimewekwa katika VA au KVA, kubadilisha kwa hesabu lazima kufanyike ili kuamua uwezo halisi wa kVA wa mashine. Kwa maelezo zaidi juu ya ukubwa wa Inverter inayofaa kwa ajili ya ufungaji wako, unaweza kuwasiliana Shrego ProBTech. Tafadhali, kumbuka kwamba baadhi Inverters pia ni overrated kwamba ni, wao ni rated juu ya uwezo wao halisi. Inverters ambayo ina kiwango cha 2kV (kW) inaweza kuwa na kiwango cha chini cha 1.5kV (kW). Baadhi ya wafanyabiashara wa bubious hata kuondoa lebo ya mtengenezaji na kuchukua nafasi ya lebo cloned na rating ya juu. Hii ni hatari sana na kwa hiyo ni bora kushauriana na wataalamu wa kiufundi kabla ya kununua inverter na vifaa vingine vya umeme. Inverter au UPS haipaswi kuwa na mzigo juu ya 80% ya uwezo wake wa kiwango kwa sababu tatu za msingi: Kwanza, uwezekano wa upanuzi wa mzigo wa baadaye. Pili, ufanisi wa juu wa mashine. Loading mashine kwa mzigo kamili itasababisha ufanisi wa chini (utendaji) na kwa hiyo kushindwa kabla ya kukomaa. Inverters nyingi ni overrated na inaweza kuanza kuonyesha overload hata chini ya 80% ya mzigo. (ii) Hali ya mkondo mfupi. Jambo jingine kwamba Inverter inaweza kuhisi kama overload ni wakati kuna kifupi-mzunguko juu ya mstari. Wakati kuna daraja kati ya Neutral na mstari (kuishi) cables, Inverter inaona kama overload kwa sababu itakuwa kuchora nguvu sana sasa zaidi ya kile Inverter inaweza kushughulikia. (iii) Inverter Fault. Inverter pia inaweza kuonyesha overload kama matokeo ya kosa la ndani juu ya bodi ya mzunguko. Tafadhali wasiliana na fundi wa vifaa ili kurekebisha. (iv) Battery Low Volt. Kosa jingine kwamba inverter inaweza kutafsiri kama overload ni betri chini volt. Wakati voltage ya betri inashuka chini ya thamani ya kuweka kwa Inverter, inaweza kusababisha Overload mwanga au kuonyesha kwenye skrini Inverter kuja juu. Ikiwa baada ya kuchaji betri kosa linatoweka, basi ni voltage ya chini ya DC, vinginevyo, endelea na hali zinazowezekana zilizotajwa hapo juu: Kabla ya kuunganisha nyaya na ukubwa wa kebo: Kabla ya kufunga Inverters, tahadhari lazima ichukuliwe kwa hesabu za nadharia zinazohusika katika kuchagua ukubwa wa kebo na aina, pamoja na nambari za rangi za kiwango cha kimataifa, jinsi mashine inaunganishwa na mzigo na chanzo cha usambazaji. Ukubwa usiofaa wa kebo ni msiba wa moto, kumaliza kwa urahisi na waya usiofaa ni ajali nyingine inayosubiri kutokea. Matukio mengi ya moto katika nyumba na ofisi husababishwa na kumaliza huru au makosa (si ya daraja au chini ya ukubwa) cable. (tazama maelezo yangu juu ya Sababu za Kawaida za Moto Katika Nyumba na Ofisi) kwa maelezo juu ya hili. Uwezo wa kubeba mkondo pamoja na nambari za rangi za nyaya lazima zichaguliwe kwa uangalifu. Kuna Marekani, Uingereza, Ujerumani nk rangi codes kwa ajili ya nyaya ambayo lazima kufuata kidini. Pia, ukubwa wa pembejeo ya kuingia na pato (socket na plugs) lazima kuwa ya kutosha kwa mahitaji ya mzigo wa mashine. Breaker (s) au fuse ya ukubwa unaofaa lazima pia kuingizwa katika maeneo sahihi kwa ajili ya ulinzi wa si tu vifaa lakini pia watu. Inverter mzigo lazima kuwa kabisa kutengwa kutoka kwa mzigo wengine katika kituo na vifaa vya kufuzu na ulinzi kama vile MCBs na ELCBs lazima kutumika wote kwa ajili ya pembejeo na pato la inverter. Inverter ya umeme lazima kuondolewa kwenye bar ya ardhi ya jengo, ambayo lazima kwa upande kuzikwa kwa wingi wa jumla wa ardhi. Inverter inaonyesha kushindwa kwa huduma (Batri haijajaza): Tatizo hili hutokea wakati Inverter haiwezi kupata usambazaji kutoka kwa chanzo. Wakati hii hutokea, Inverter inaweza tu kukimbia juu ya hali ya betri lakini haiwezi malipo. Hii ni pamoja na sauti beep kwamba kurudia mwenyewe kila sekunde (kutegemea Inverter Configuration). Kuna mambo mengi ambayo yanaweza kuwa na makosa, baadhi ya ambayo ni: fuse blown au kuvunja kuvunja, kutokuwepo kwa usambazaji kutoka kwa chanzo au mzunguko mbaya wa pembejeo au voltage. Jambo jingine ambalo laweza kuwa na hatia ni kebo iliyovunjika au transformer iliyofunguliwa. Jambo la kwanza kuthibitisha wakati Inverter inaonyesha utility kushindwa au Hakuna pembejeo ni: Upatikanaji wa ugavi kutoka chanzo. Angalia fuse au mzunguko wa kuingilia. Kama plug na soketi ni kutumika kuunganisha pembejeo kwa chanzo cha umeme. Kuangalia plagi na soketi kuhakikisha hakuna uhusiano huru au wazi na pia kuhakikisha fuse juu ya plagi ni sawa. unaweza pia kufanya kuendelea na mviringo mfupi mtihani juu ya kebo ya usambazaji (kufanywa na fundi wa kufuzu). Unaweza kuhitaji mtihani transformer kutengwa pia na moduli surge kama inapatikana. Katika kesi ya fuse blown, fuse si tu blow, ni unasababishwa na kosa. Kasoro hiyo yaweza kuwa ya muda mfupi au ya kudumu. Kwanza lazima kuanzisha anomaly kwamba kusababisha fuse kuvunja katika nafasi ya kwanza kabla ya kufanya badala, vinginevyo kosa sawa kama si kuondolewa itabomoa fuse tena na inaweza kusababisha uharibifu zaidi kwa inverter. Unaweza kubadilisha fuse na kiwango sawa cha sasa kama moja blown au rejea kwa fundi wa sifa kwa ajili ya kubadilisha. Je, si kutumia overated fuse vinginevyo, unaweza kuharibu Inverter yako. Ikiwa inverter ina kiunganishi cha circuit breaker badala ya fuse, unaweza kuweka upya kiunganishi tu baada ya kosa ambalo lilisababisha kosa hilo kuondolewa. Katika kesi ngumu, mzunguko wa kuongezeka kwa Inverter inaweza kuwa imeathiriwa au baadhi ya vipengele vingine vya nguvu kwenye bodi, katika kesi hiyo utahitaji kutaja muuzaji wako wa bidhaa, Mtaalamu wa Inverter kwa ukarabati, au tu piga simu Shrego ProB Tech kwa msaada. Inverter Overheating: Inverter Overheating inaweza kusababishwa na mambo mengi, lakini sababu ya kawaida ni kutofaulu kwa shabiki au mzigo wa ziada. Inverters ni vifaa vya kupoza kwa ajili ya vifaa vya umeme kwenye ubao, ambayo hutokeza joto wakati wa kazi. Kipaza-hewa hufanya hivyo kwa kutawanya joto hili lililotokezwa kwa jirani. Wakati shabiki kushindwa, au joto mazingira ni ya juu sana, joto kujenga inaweza kusababisha hizi sehemu nusu-cconductor kulipuka na kushindwa. Kwa sababu hii, kuhakikisha kwamba chumba ambapo Inverter ni imewekwa inaruhusu kwa kuvuka uingizaji hewa na ni pana. Kwa hiyo, katika kila hatua katika wakati, shabiki lazima kuwa kazi wakati Inverter ni katika operesheni na joto ni kuzalishwa. Inverter ina vifaa vya thermostat ambayo hufanya kipepeo cha hewa cha joto cha kawaida, na betri imepita hatua ya malipo ya jumla. Kama ni nyaya kwamba ni overheating, basi mawasiliano ya cable lazima kuchunguzwa kwa mawasiliano ya sehemu (kuunganisha huru) au overload. Overheating pia inaweza kutokea kutokana na kuendesha Inverter katika mazingira duni uingizaji hewa. Hii inaweza kutokea wakati Inverter ni kazi chini ya hali ya kawaida ya kazi. Moja ya hii ni wakati mains Voltage au Frequency ni abnormally maskini. Hii ni ya kawaida zaidi wakati wa kuendesha Inverter na Jenereta. Jenereta wengi kawaida kuwa na matatizo duni Frequency na au Voltage ambayo inaweza kusababisha Inverter kufanya kazi chini ya hali ya mkazo na hatimaye inaweza kusababisha Inverter kushindwa. Humming pia inaweza kusababisha wakati Inverter ni abnormally overloaded au chini ya hali ya mkondo mfupi. 7. overload ya pato: kosa hili inaweza kutokea wakati kuna daraja kati ya awamu na neutral ya cables pato au kati ya awamu na ardhi. Katika kesi hiyo, kama hakuna circuit breaker kuingizwa katika pato la Inverter kabla ya kulisha mzigo, hii inaweza maoni kwa Inverter kusababisha kushindwa. Kama kosa kama hilo hutokea, kwanza ya yote kupata njia ya kutenganisha mzigo kutoka Inverter, kisha kubadilisha cable na kurudi mzigo nyuma ya Inverter. Kama kuna breaker katika pato la Inverter, ni lazima safari ya kuokoa Inverter. Overload pia inaweza kutokea wakati Inverter nguvu mzigo zaidi ya uwezo wake wa kiwango. Katika kesi hiyo, Inverter itakuwa beep kwa sekunde chache na kisha kuzima yenyewe. Hakikisha kwamba mzigo wa ziada ni kuondolewa na kuweka upya breaker. Inverters baadhi pia inaweza kuonyesha Overload kabla ya kuzima wakati betri ni chini sana kama ilivyoelezwa hapo awali lakini, kosa hili itafuta mbali baada ya betri ni recharged. Wakati inverter shuts down kama matokeo ya betri ya chini, si kujaribu kubeba inverter mara moja mains ni sasa, lakini kuruhusu betri ya malipo kwa asilimia fulani kabla ya kuunganisha mzigo nyuma. Overload pia inaweza kuwa kama matokeo ya vipengele blown juu ya bodi Inverter. Inverter On Bypass Mode: Inverter inaweza tu kusambaza mzigo wakati wa umeme, lakini shutdowns mara moja baada ya umeme ni mbali. Hii inaweza kutokea wakati Inverter si vizuri powered up. Ili kuendesha Inverter, bonyeza ON (nguvu) kifungo mpaka Inverter inakuja online au kufuata maelekezo juu ya kuendesha. Ikiwa haijui wakati wa kufunga, inaweza kuwa ishara ya kosa au kubadili vibaya au hata kebo ya ishara iliyokatwa. Pia, kama mzunguko wa DC ni kuvunjwa, haitakuwa kuruhusu mtiririko wa sasa kutoka betri kwa mzigo. Hii inaweza pia kuwa kama matokeo ya kosa la ndani ndani ya Inverter. Tafadhali kumbuka kwa fundi wa kitaalamu au muuzaji wa bidhaa kwa ajili ya ukarabati: Inverter inageuka dakika chache baada ya umeme ni mbali, hali hii ni tofauti na hali ya Bypass ilivyoelezwa hapo juu, kwa kuwa si ya papo hapo. Inverters inaweza kuwa katika hali ya betri wakati kuna kushindwa kwa huduma, lakini huchukua sekunde chache au dakika, kisha huondoka. Katika kesi hii, hakikisha kwamba betri ni sawa, kwa sababu betri mbaya haiwezi kushikilia malipo na kwa hivyo pia haiwezi kuondoa mzigo. Inverter inarudi nguvu kwa pembejeo Wakati Inverter inarudi nguvu kwa pembejeo, ni ishara ya kosa. Relay iliyoharibiwa au AVR wakati mwingine inaweza kuwa na jukumu kati ya vipengele vingine. Tafadhali, wasiliana na Mtaalamu wako au Shrego ProBTech kwa msaada. Inverter ni ya kushangaza. Inverter ya mshtuko inaweza kuwa ishara ya sehemu iliyoshindwa ambayo inasababisha uvujaji, kebo iliyovunjika ambayo inasababisha uvujaji na Inverter iliyofunuliwa. Inverters lazima kuwa na uwezo wa kuunganisha umeme wa umeme wa umeme wa umeme wa umeme wa umeme wa umeme wa umeme wa umeme wa umeme wa umeme wa umeme wa umeme wa umeme wa umeme wa umeme wa umeme wa umeme wa umeme wa umeme wa umeme wa umeme wa umeme wa umeme. Inverter ya Inverter ya Inverter ya Inverter ya Inverter ya Inverter ya Inverter ya Inverter ya Inverter ya Inverter ya Inverter ya Inverter ya Inverter Chini ya usimamizi mzuri, Inverter ni mashine ya kudumu ambayo haiwezi kuendeleza kosa ikiwa inafanywa kazi chini ya hali sahihi. Hali ya mazingira: joto na vumbi hucheza jukumu muhimu sana katika utendaji wa Inverter. Joto la juu husababisha joto kupita kiasi kwenye transformer na vipengele vingine vya Inverter. Kwa kuongezea, kila ongezeko la joto la 8 ° C hupunguza maisha ya betri kwa nusu. Inverter lazima kwa hiyo imewekwa katika mahali ambapo kuna hewa msalaba na bure kutoka unyevu. Vumbi zilizokusanywa kwenye bodi ya mzunguko wa Inverter pia zinaweza kuingiliana na unyevu kuunda filamu ya conductive na kusababisha mzunguko mfupi, na hivyo kuharibu bodi. Inaweza hata kusababisha tukio la moto. Kwa hiyo ni muhimu kuwa na Inverter yako au UPS kutumika mara kwa mara na wafanyakazi wa kiufundi wenye sifa. Unaweza kuwasiliana na Shrego ProBTech kwa ajili ya matengenezo ya kuzuia wakati wowote wewe kuhisi Inverter yako ni kutokana na huduma. Uwezo wa kuendesha umeme wa voltage na frequency (VF) ni muhimu kwa sababu inaweza kuathiri utendaji wa inverter. Voltage fluctuation inaweza kurekebishwa na Voltage Regulator (VRS) ambayo hulipa kwa voltage ya juu au ya chini, kulingana na kesi, au kifaa cha kuvunja voltage (VGA) ambacho hupunguza usambazaji kwa mashine wakati wowote inapotoka nje ya safu ya kuweka. Voltage ya AC inayoruhusiwa kwa Nigeria ni kati ya 220V na 230V, wakati mashine zingine bado zinaweza kuvumilia kati ya 190V. 270V, kulingana na muundo. Hata hivyo, tofauti na voltage, mzunguko hauwezi kurekebishwa na Voltage Stabilizer au Overvoltage Cut-Off Device; lazima kurekebishwa kutoka kwa chanzo cha usambazaji, yaani, ama kutoka kwa Jenereta ya AC au kutoka kwa PHCN. Uwezo wa frequency wa mashine za AC ni 50Hz. Wakati hii ni nje ya mbalimbali, Inverter au UPS itakuwa kukataa na betri kuacha malipo mpaka hii inakuwa kawaida tena. Inverters hazipati malipo kwa muda mrefu wakati betri zinapojazwa na jenereta, lakini hufanya vizuri wakati zinapojazwa na chanzo cha huduma ya umma na kinyume chake, majibu yangu daima yamekuwa kuangalia mzunguko wa jenereta inayotumiwa kwa malipo ambayo mara nyingi ni juu au chini ya dirisha la mzunguko linaloruhusiwa. Kama voltage au mzunguko ni juu au chini ya mbalimbali kuruhusiwa, betri itakuwa si kushtakiwa vizuri na matokeo itakuwa chini ya muda wa kuhifadhi. Ukubwa usiofaa wa kebo na uhusiano wa bure kwenye viunganishi vya betri: Ukubwa usiofaa wa kebo kwa kuunganisha betri au mawasiliano ya bure yanaweza kusababisha moto na kupoteza maisha katika hali mbaya zaidi au utendaji usio wa kawaida au muda mfupi wa betri na maisha. Mahesabu sahihi ya cable msalaba eneo kushughulikia mahitaji ya mzigo lazima kuhakikisha kabisa. Ukubwa wa kebo, hasa wakati wa nyaya za betri zimeunganishwa sambamba, inaweza kusababisha kuvunjika kwa insulation na kwa hivyo kushindwa kwa kebo na betri. Inverter: Inverter inaweza kuwa na uwezo wa kuzalisha nishati ya juu ya uwezo wa kiwango cha juu wa inverter, na inaweza kuwa na uwezo wa kuzalisha nishati ya juu ya kiwango cha juu cha inverter. Kwa nini betri inaweza kushindwa kwa urahisi (kwa Inverter) Nimekuwa kualikwa na wateja katika nyumba nyingi na ofisi kuja na kuwa na betri zao Inverter. Wateja wengi wanalalamika kuwa betri zao zina umri wa miezi michache tu na bado zinashindwa ghafla, zinaweza kuwa na umri wa miezi minne. Ni mbaya sana. Kila mara ninaposikia hadithi kama hiyo, mimi huwa na huruma kwa wateja hawa ambao baada ya kutumia mamia ya maelfu kwenye betri, wakitumaini kutatua matatizo yao ya umeme bado hawawezi kupata bora kutoka kwa uwekezaji wao. Ninahuzunika kila mara ninaposikia malalamiko kama hayo. Wengi wa kushindwa hizi inaweza kuepukwa kama mtumiaji ni kupewa taarifa ya kutosha juu ya kwa nini kushindwa hizi mapema kutokea na jinsi ya kupunguza dhidi yake. Kwa hiyo, tumekuwa na muda wa kuelezea baadhi ya sababu za kawaida kwa nini betri inaweza kushindwa kabla ya muda wao iliyoundwa. Wakati betri inashindwa, ni rahisi kwa wateja kudhani kwamba betri hiyo ni ya chini ya kiwango au labda ni betri iliyorejeshwa, wakati hii ni kweli katika kesi zingine, katika kesi nyingi sio. Hata baadhi ya bidhaa bora zaidi za betri zinaweza kushindwa mapema ikiwa taratibu sahihi za matengenezo hazifuatwi. Batri, kama vifaa vingine, ni kifaa cha kutoweka, ambayo inamaanisha kuwa ina mzunguko wa malipo na kutolewa, baada ya hapo itaanza kuharibika hadi vifaa vyake vya kazi vimechoka kabisa. Mbali na hayo, betri pia ina joto la kazi linalofaa ambalo lazima lifanye kazi, juu au chini ambayo itaathiriwa vibaya. Chini ni baadhi ya sababu kwa nini betri inaweza kushindwa kabla ya muda wao iliyoundwa. (1) SUB-STANDARD PRODUCT. Hakuna shaka kwamba bidhaa nyingi za betri kwenye soko leo kama hapo awali ni chini ya kiwango, wakati baadhi yao ni refurbished. Hii ndiyo sababu uteuzi wa betri lazima kufanywa kwa uangalifu. Wateja wengi huchagua betri yoyote ya bei nafuu ambayo pesa zao zinaweza kumudu au kupata mtandaoni na wanatarajia kupata bora zaidi kutoka kwao. Ukweli ni kwamba, hakuna kitu kizuri kinachokuja kwa bei nafuu. Ikiwa unaangalia kitu cha bei nafuu, sio kama betri, kwa sababu betri ni nguvu kuu ya Inverter yako, bila betri, hakuna Inverter. Ikiwa itashindwa, mashine yako ya Inverter ni kama sanduku la kawaida. Inverter bandia inaweza kurekebishwa, lakini si betri bandia. Hiyo ndiyo sababu katika Shrego ProBtech, sisi daima kusisitiza kwa wateja, juu ya mambo mengine ya kuondoka ugavi wa betri kwetu, na baadhi ya wale ambao kufanya vinginevyo wamekuwa na wito kwetu miezi michache baadaye kwa ajili ya kubadilisha betri, hivyo patetic. Sisi kwa uangalifu duka kwa ajili ya betri zetu kutoka wazalishaji kuaminika moja kwa moja, kwamba ni kwa nini tunaweza kumudu kutoa mwaka dhamana na uaminifu. Mzunguko wa kuchaji: Bateria, kama kifaa kingine chochote, ina idadi yake mwenyewe ya mzunguko wa kuchaji na kutolewa, baada ya hapo itaanza kuonyesha dalili za uharibifu. Kwa maneno mengine, inaweza kutoweka baada ya vitu vyenye nguvu vilivyo ndani yake kumalizika. Wakati unaotumiwa kukamilisha mzunguko huu unategemea kiasi cha matumizi. Bateria ambayo ni kuwa kina discharged daima na mzigo mzito inaweza kuchukua muda mfupi kukamilisha mzunguko wake wa maisha kuliko nyingine ambayo hubeba mizigo ndogo na kudumisha malipo kamili wakati wote. Kwa hiyo sisi daima kushauri wateja wetu kuepuka kama iwezekanavyo kuongeza juu ya sasa mahitaji mizigo kama vile friji, maji ya joto, jiko umeme, kushinikiza chuma na hali ya hewa kwa inverter. Ingawa hii inaweza kufanya kazi, kulingana na nguvu rating ya Inverter, kiwango cha discharge itakuwa juu sana juu ya betri ambayo inaweza kusababisha kushindwa mapema. 3) Uchaji wa chini au wa juu: Moja ya sababu kuu za kushindwa kwa betri ni kuchaji kupita kiasi au chini ya kuchaji. Wakati betri ni daima chini ya malipo au kushoto katika hali ya chini ya malipo kwa muda mrefu, ni polepole husababisha sulphate kuongoza katika betri crystallize ambayo husababisha uwezo wa kuhifadhi betri kuwa kudumu kuharibiwa na kupunguza betri ya vifaa vya kazi ambayo ni wajibu kwa uwezo wake wa juu na upinzani wa chini. Uharibifu wa kugeuka unaweza kurekebishwa ikiwa betri inahudumiwa mapema kwa kutumia voltage maalum ambayo husaidia kuyeyusha fuwele na hivyo kuleta sulfate kwa hali yake ya kazi, lakini sulfation isiyoweza kurekebishwa haiwezi kurekebishwa. Inaanza wakati betri imebaki katika hali ya chini au iliyotolewa kwa muda mrefu sana. Hii ni kwa nini si nzuri kuondoka betri katika hali ya discharged kwa muda mrefu. Kuendelea overcharging kwa upande mwingine inaweza kusababisha electrolyte kuchemka na outgassing ambayo hatimaye kuharibu seli katika betri. BATRI: BATRI pia kushindwa wakati kiwango cha maji distilled katika betri (Tubular) ni chini. Hakikisha kwamba kiwango cha electrolyte katika betri si chini wakati wote. Bidhaa za kisasa za betri za tubular zimetengenezwa na kiashiria cha kiwango cha kioevu ambacho husaidia kuimarisha kiwango cha electrolyte kwenye seli za betri. "Hii ni kwa sababu kiwango cha maji haipatikani chini ya kiwango cha ""SULFATION"" (SULFATION) cha chini, na hali hii hutokea wakati betri haijajazwa kwa muda mrefu." Betri zinahitaji kuchajiwa tena na tena ili sulphate iendelee kufanya kazi. Batri hupoteza 2% ya malipo yake kila siku 30 na ikiwa hii inaachwa kwa muda mrefu sana bila kuchaji, basi sulfation huanza. Kama betri sulfated ni kushikamana na Inverter, hata kama haijawahi kutumika kabla, haiwezi kuwa na ufanisi tena. Vipengele vya kuepuka kushindwa kwa betri: Weka joto mbali. Joto ina athari mbaya sana juu ya maisha ya betri na utendaji wa jumla. Kwa kweli, kila kuongezeka kwa joto la digrii 8 hupunguza maisha ya betri kwa nusu. Kwa mfano, betri iliyoundwa kwa miaka minne ikiwa inafanya kazi chini ya joto la digrii 25C, itaendelea kwa miaka miwili tu ikiwa inafanya kazi chini ya joto la digrii 33C. Katika Shrego Pro, kuzingatia hali ya mazingira ambayo betri itaendeshwa ni muhimu sana, ndiyo sababu betri zetu hazishindwa mara chache, haswa ikiwa hali zingine za matengenezo kama tulivyopendekeza zinafuatwa pia. Kwa mfano, betri zilizowekwa karibu na chanzo cha joto, kama vile jikoni, bila shaka zitashindwa katika muda usio na mbali. "Kufanya ""Mfumo wa Bateria"" Uwe mfupi: Watu wengine hujaribu kupima uwezo wa betri kwa kufunga vituo viwili (chanya na hasi) wakitarajia moto mkali." Hii ina athari mbaya sana kwa betri kwa kudhoofisha seli za ndani za betri, na hivyo kupunguza maisha yake. Uchafu na uhusiano wa kupunguzwa: uchafu kwenye terminal ya betri au uhusiano wa kupunguzwa unaweza kusababisha upinzani mkubwa kwenye terminal ya betri ambayo huathiri utendaji wa betri. Weka vituo safi na vyenye mafuta sikuzote. BATARIA ZA BARANDI ZIYOTO: BATARIA za BARANDI ZA BARANDI ZA BARANDI ZA BARANDI ZA BARANDI ZA BARANDI ZA BARANDI ZA BARANDI ZA BARANDI ZA BARANDI ZA BARANDI ZA BARANDI ZA BARANDI ZA BARANDI ZA BARANDI ZA BARANDI ZA BARANDI ZA BATARANI: Mmoja wa wateja wangu alitaka kuunganisha betri mbili za 12V kwa uwezo wa 200AH. "Nilimuuliza kwa nini anafanya hivyo na jibu lake ni rahisi, ""Akaenda kufanya kazi"" maana, ""itakuwa kazi"" Kwa kweli mpangilio huu utafanya kazi, lakini ujinga wa mtu huyu ni kwamba wakati hii inaweza kufanya kazi kwa muda, betri ya 200AH hivi karibuni itaharibiwa na 100AH." Wakati wa mchakato wa kuchaji, chaja ina sensor ambayo inahisi voltage katika terminals ya betri ambayo hutumia kudhibiti kiasi cha malipo ya sasa ili kutoa kwa betri. Wakati chaja inahisi kwamba voltage katika terminal ya betri inakaribia malipo kamili, hupunguza mzunguko wa malipo kutoka hatua ya malipo ya wingi hadi hatua ya kunyonya, kisha hatua ya malipo ya kuelea. Kwa hivyo, kwa kuwa chaja inaona betri mbili kama moja, sio mbili, wakati betri ya 100Ah imejaa, 200Ah bado ina njaa ya malipo, na matokeo ni kwamba betri ya 200Ah haitaweza kufikia malipo kamili wakati wowote, ambayo kama ilivyojadiliwa hapo awali ni moja ya sababu kuu za kushindwa kwa betri. Wakati wa kutolewa, betri zilizounganishwa kwa mfululizo zina voltage iliyoongezeka, lakini sasa ni sawa, kwa hivyo Inverter inachagua sasa ya betri ndogo, ambayo katika kesi hii ni 100AH kama sasa ya kufanya kazi nayo, kwani inaona betri mbili kama kitengo kimoja na hivyo kupunguza wakati wa kuhifadhi. Kwa hiyo, ni kosa kuchanganya betri ndogo na kubwa na vilevile betri mpya na za zamani pamoja. Vivyo hivyo ni kweli kwa ajili ya betri ya wazalishaji tofauti (bidhaa). "Kuweka ""msaada"" wa umeme kwa betri: ""Mimi nimesikia malalamiko mengi kutoka kwa wateja kwamba betri zao hufanya vizuri baada ya kuchaji na usambazaji wa huduma ya umma lakini hufanya vibaya baada ya kuchaji na jenereta yao ya petroli." Kuna maelezo mawili makuu ya jambo hilo. Wao ni Voltage na Frequency. Kiasi hiki cha umeme ni muhimu sana kwa vifaa vya elektroniki kwamba tofauti yoyote ya kawaida itathamini utendaji wa inverter na vifaa vingine vya elektroniki. Wakati voltage tofauti inaweza kudhibitiwa na Voltage Stabilizer, mzunguko kwa upande mwingine haiwezi. Hivyo, wakati Generator Technician inaweza kuwa na uwezo wa kuweka karibu na kamili voltage wakati wa huduma, wengi wao kuwa na suala na kurekebisha mzunguko. Voltage inaweza kuwa kutoka 220V hadi 240V, na frequency inaweza kuwa kutoka 50HZ hadi 240V. 2) ni abnormal na inaweza kuwa si kukubaliwa na wengi wa vifaa vya elektroniki. Inverter inaweza kuwa na nguvu ya frequency ya umeme, kama vile stove, fan, umeme, umeme, umeme, umeme, umeme, umeme, umeme, umeme, umeme, umeme, umeme, umeme, umeme, umeme, umeme, umeme, umeme, umeme, umeme, umeme, umeme, umeme, umeme, umeme, umeme, umeme, umeme, umeme, umeme, umeme, umeme, umeme, umeme, umeme, umeme, umeme, umeme, umeme, umeme, umeme, umeme. Matumizi ya umeme duni au maji ya madini ya kuongeza umeme katika kesi ya betri ya tubular (seli ya mvua) itasababisha kutu ya seli na kushindwa kwa muda wa betri. Matumizi ya betri: Kama ilivyoelezwa hapo awali, ikiwa betri haitatumika kwa muda mrefu, inapaswa kuhifadhiwa katika mazingira ya baridi bila joto na katika hali ya malipo kamili. Kuchaji mara kwa mara ni muhimu mara kwa mara, sema mara moja katika miezi miwili hadi mitatu ili kukomesha betri kujiondoa. Pia, wakati wa matumizi kuepuka juu ya discharging betri na kuwa na uhakika wa recharge baada ya kila matumizi ya muda mrefu au discharge kina. Ikiwa betri yako inakuwa moto sana, inaweza kuwa ishara ya kushindwa kwa betri. Kuzima usambazaji kutoka Inverter na wito eXpert karibu kupata ni kupatikana na kama ni lazima kubadilishwa. Betri inayopaa joto kupita kiasi yaweza kulipuka na kusababisha moto. # 2 Usitumie betri ya gari kwa inverter yako kwani haijaundwa kwa kusudi hilo. Batri ya gari ni iliyoundwa kwa ajili ya kuanza haraka kama katika kesi ya gari kuanza, na si kwa ajili ya matumizi ya kuendelea. Mbali na hilo, pia si iliyoundwa kwa ajili ya trickle malipo kwamba Inverter hutoa. # 3 Wakati wa kuchagua betri, ukubwa huamua nguvu, ukubwa huu unakuja kwa namna ya uzito, kwani ukubwa wa casing inaweza kuwa ya kudanganya. Katika kesi nyingi, kubwa zaidi ya mwili sze na uzito corresponding, kubwa zaidi ya AH rating. Aina za betri za kawaida za AH ni: 5AH, 7AH, 18AH, 75AH, 100AH, 150AH, 200AH, 1000AH na zaidi. Thamani hizi kuamua uwezo wa betri. Zaidi thamani hii, muda mrefu zaidi ya kuhifadhi. Mbali na thamani ya AH ya betri, jambo jingine la kuzingatia ni voltage. Ina betri za 2V, 6V, 12V, 24V na zaidi. Voltage thamani huamua idadi ya betri kama kuwa kushikamana pamoja katika kamba kutoa voltage taka ya kuendesha Inverter. UPS ni mashine ya umeme ambayo hutoa umeme wa dharura kwa vifaa kwa muda mfupi wakati usambazaji wa umeme unashindwa. Hii ni kwa msaada wa betri ya ndani iliyowekwa katika UPS. UPS ni muhimu kwa ajili ya ulinzi wa data katika athari ya ghafla nguvu kukatika au kushindwa kabisa. Kwa mfano, inazuia kompyuta au seva kutoka kuanzisha upya au kuzima wakati nguvu surges, sags au kabisa kushindwa, ambayo inaweza kusababisha hasara ya thamani na data unrecoverable. Baadhi ya UPS pia kutoa voltage udhibiti katika pato, hivyo hata wakati usambazaji ni unregulated, pato smoothed ni alitoa kwa mzigo. Kwa hiyo, katika kesi hii, UPS pia hutumika kama kiimarishaji wa voltage. UPS pia husaidia kutoa longevity kwa vifaa ni kulinda, kama inasaidia cushion madhara ya hali ya nguvu erratic juu ya vifaa ni kulinda. UPS ni aina ya mfumo wa umeme wa umeme wa umeme wa umeme wa umeme wa umeme wa umeme wa umeme wa umeme wa umeme wa umeme wa umeme wa umeme wa umeme wa umeme wa umeme wa umeme wa umeme wa umeme wa umeme. Kuna aina nyingine kama Line Interactive, Delta Conversion, Ferro Resonance na kadhalika, lakini nitaweka mipaka ya majadiliano yangu tu kwa aina hizi mbili za msingi za kawaida katika nyumba na ofisi. Aina hii ya UPS haiwezi kuhakikisha usalama wa data kama inatumia relay kwa kubadili. Ni anaendesha daima juu ya mains (msaada wa umeme) na swichi kwa hali ya betri tu wakati voltage huongezeka au huanguka chini ya thamani iliyopangwa mapema. Data inaweza kupotea wakati wa kipindi hiki kifupi cha kubadili. Aina hii ya UPS inapatikana chini ya 1KVA. Aina hii ya UPS hutumiwa kwa vifaa ambavyo ni nyeti sana kwa mabadiliko ya nguvu, kama vile seva, routers, swichi na kompyuta za kibinafsi. Kwa aina hii ya UPS, hakuna kubadili kweli hufanyika tangu betri ni daima kushikamana na inverter. Aina hii ya UPS ni ilipendekeza kwa ajili ya usalama wa data. Ingawa gharama ya awali ya UPS hii inaweza kuwa ya juu kuliko mwenzake wa nje ya mtandao, gharama ya matengenezo ni ya chini kwa sababu ya maisha ya betri ya muda mrefu. Faida nyingine ya aina hii ya UPS ni katika uwezo wake wa kutoa firewall umeme kati ya nguvu utility inakuja na vifaa nyeti. Inaweza kukabiliana na mbalimbali ya pembejeo mzunguko mbalimbali hivyo kwamba mzunguko wa pato inaweza kudumishwa ndani ya dirisha kukubalika. UPS ni si inverter; ni iliyoundwa tu kwa ajili ya nyuma kwa muda mfupi, kusema dakika 5 hadi 20 juu ya betri. Matumizi ya muda mrefu inaweza kusababisha kuzima ghafla ya mzigo na maisha ya chini ya betri. UPS lazima daima kushikamana na chanzo cha umeme (PHCN, jenereta au solar panel) na haipaswi kuruhusiwa kufanya kazi kwa betri kwa muda mrefu. Kufanya hivyo kutapunguza muda wa kuishi wa betri. UPS haipaswi kuwa overloaded. Kila UPS ina uwezo wake ulioandikwa kwenye bamba lake la jina (kwa VA, WATTS, KVA, KW, et cetera). Kila kifaa cha umeme kinachohusishwa na UPS kina kiwango chake cha matumizi ya umeme au kiwango cha sasa kilichoandikwa. Uwezo wa jumla wa vifaa hivi pamoja haipaswi kuzidi 80% ya uwezo wa kiwango cha UPS. Overloading inaweza kuharibu kabisa UPS, au angalau kutupa mbali mzigo wote. UPS lazima kuwa kabisa nguvu juu na kifungo laini kabla ya kuweza kuhifadhi wakati wa kukatika kwa umeme au fluctuations. Hakikisha unazima UPS wakati wa kuondoka nyumbani au kufunga kwa ajili ya biashara. Hii itahakikisha kwamba haitaisha betri wakati kuna kukatika kwa umeme. UPS inapaswa kusafishwa na mtaalamu angalau mara moja kwa miezi sita katika mazingira yenye vumbi au kila mwaka katika mazingira yasiyo na vumbi. Hakikisha kwamba hakuna uhusiano huru juu ya UPS terminals. Kuunganisha huru ni moja ya sababu kuu ya kuchoma ya cables na katika baadhi ya kesi moto mlipuko. Wakati wa huduma, mwambie fundi kuangalia terminals kwa ajili yenu ili kuhakikisha ni umeme sauti na imara. Kwa ajili ya maombi ya viwanda yanayohusisha UPS ya uwezo mkubwa, hakikisha kwamba fundi wa kushughulikia ufungaji hutoa ulinzi wa kutosha. "Kufanya kazi kwa kutumia inverters na jenereta ya jua, ni muhimu sana kwa sababu ina ""mfano"" wa kuendesha gari la umeme." Jibu lake lilikuwa <unk>1,500 (Naira ya Nigeria). Kwa mfano, mtu mmoja alikuwa na jenereta ya 2.9KVA ambayo ilifanya kazi kwa muda mrefu. Nilimhoji kuhusu kiasi anachotumia ili kuchochea jenereta yake. "Kama ilivyoelezwa hapo juu, ""Kufanya kazi kwa saa 4 kwa siku kwa mafuta ya 1,500 huchukua siku 4, ikimaanisha 1,500 huchukua wastani wa saa 16.""" Hii inamaanisha wastani wa € 100 kwa saa. Kama yeye alikuwa kutumia jenereta kwa saa 12 kwa siku kama mimi kutumia inverter yangu (7pm 7am), yeye itakuwa kutumia jumla ya (1,200 X 7) = 8,400 katika wiki moja. Inverter betri chini ya hali ya kawaida na kwa matengenezo ya kawaida ni iliyoundwa kudumu kwa wastani wa maisha ya miaka 4 hadi 5 kabla ya kubadilishwa inatarajiwa, lakini kuwa kihafidhina, mimi ni kutumia wastani wa miaka 4 kwa ajili ya hesabu yangu. Kwa hiyo katika miaka minne, rafiki yangu itakuwa kutumia (438,000 kwa mwaka X 4 miaka) = 1,752,000 juu ya mafuta peke yake, mbali na gharama ya huduma ya jenereta na matengenezo na gharama ya awali ya kununua jenereta. Kwa mfano, kwa 1.5KV inverter, gharama ya jumla ya usakinishaji ni $ 322,000. Kwa mujibu wa takwimu hizi za uchambuzi, ni dhahiri kwamba gharama ya kuendesha jenereta kwa miezi 8 hadi 9 tu imefunika kile ambacho inahitajika kuanzisha Inverter ya 1.5KVA na betri ambazo zitaendelea kwa miaka 4 kabla ya kubadilisha betri. Hii haijumuishi gharama ya kununua jenereta yenyewe ambayo ni karibu £ 120,000 Kwa hivyo na Inverter, nimeokoa gharama ya jumla ya £ 1430,000 (Mamilioni moja, mia nne na thelathini naira tu) wazi kwa kipindi cha miaka minne. Sasa, hiyo ni tu athari ya gharama. Inverter ina faida nyingine ambazo huenda usikuzingatia, hapa ni chache kati yao: (2) Kwa Inverter, unaweza kulala usiku kucha bila kusumbuliwa na haja ya kuzima au kuongeza mafuta kwa jenereta. (3) Wewe si kusumbua mwenyewe na jirani na kelele ya jenereta yako. Baadhi ya vitongoji hata kuruhusu kuendesha jenereta usiku kwa sababu za usalama. Katika ujirani kama huo, wakazi wengi hulazimika kuvumilia kuzimwa kwa umeme chini ya joto kali. (4) Wewe si kuchangia uchafuzi wa mazingira unasababishwa na mono-oksidi ya kaboni madhara ambayo ni kutolewa kutoka Generator kutolea nje. (5) Huna haja ya kusumbua mwenyewe na kugeuka juu na mbali ya jenereta kila wakati nguvu ni kuvunjwa na mamlaka ya usambazaji wa huduma ya umma. Inverter moja kwa moja swishes mwenyewe kwa hali ya betri na kinyume chake wakati kuna nguvu kukatika / kurudishwa. 6 - Hutapoteza nishati kwa sababu unachukua tu kile unachohitaji kutoka kwa betri kulingana na mzigo, tofauti na jenereta ambayo huchoma mafuta bila kujali ikiwa mzigo wowote umeunganishwa au la. (7) Wewe si hatari ya upungufu wa mafuta. Wakati wa upungufu wa mafuta, huna haja ya kutumia masaa yako ya uzalishaji au mapumziko ya kusubiri mafuta kwenye kituo cha mafuta. Sababu hizi na nyingine zimetajwa ili uweze kujua ni kiasi gani umekuwa ukipoteza kwa kutotumia faida ambazo Inverter inakuandaa. Kampeni hii ya ufahamu ni kutoka Shrego ProBTech.

Simu ya mkononi: 23843453 "234343455 (mstari wa WhatsApp) """ Jopo la jua hutokeza nishati ngapi? Ingawa kuna mambo mengi yanayoathiri kiasi cha nishati ambayo paneli ya jua inaweza kuzalisha, unaweza kutarajia paneli moja ya jua nchini Marekani kuzalisha karibu kilowatt-saa 2 kwa siku, kuokoa wastani wa $ 0.36 kwa gharama za umeme kwa siku. Sasa, 0.36 haionekani kama mengi, lakini hiyo ni tu akiba ya nishati kwa jopo moja katika kipindi cha siku moja. Kuanzisha mfumo mzima wa paneli za jua, kwa upande mwingine, ingekuokoa zaidi ya $ 130 kwa mwezi (au zaidi!). Ni nini huamua ni umeme gani unaotokezwa na paneli ya jua, na unawezaje kujua kiasi cha umeme unaotokezwa na paneli moja ya jua? Hebu tujibu. Kwa mfano, unaweza kuokoa pesa kwa kutumia umeme wa jua, lakini paneli nyingi za jua za makazi leo zina kiwango cha pato la nguvu kati ya watts 370 na watts 400. Kwa mfano, paneli za jua za ukubwa wa wastani zinaweza kuzalisha kati ya 1.5kWh na 2.4kWh ya umeme kwa siku. - Jopo moja la jua hutokeza umeme wa kutosha kuendesha vifaa vidogo kama vile TV, taa, au chaja za vifaa. Kiasi cha nishati ya jua panel inazalisha inategemea kiasi cha jua jopo anapata, jopo ujenzi, paa yako sifa, na hata jinsi ya zamani jopo ni. Kuanzisha mfumo mzima wa paneli za jua hukuruhusu kuendesha nyumba yako na nishati mbadala, kupunguza utegemezi wako kwa huduma yako, na, muhimu zaidi, kupunguza bili yako ya umeme. Jopo la jua hutokeza umeme kiasi gani? Kwa mfano, paneli za jua zinaweza kutoa nguvu ya kati ya wati 370 na 400. Kwa mfano, paneli moja ya jua inaweza kuzalisha umeme wa kilowatt-saa mbili kwa siku. Hiyo ni umeme wa kutosha kutazama TV yako bila kuacha kwa karibu saa 24 kamili. "Tabuli yafuatayo inaonyesha kiasi cha umeme ambacho ""paneli ya jua ya watti 400"" ingeweza kuzalisha chini ya hali bora kwa siku moja, wiki moja, mwezi mmoja, na mwaka mmoja: ""Uzalishaji wa umeme wa ""paneli ya jua ya watti 400"" - ""Ni paneli ngapi za jua ninazohitaji kuendesha nyumba yangu?""" Hebu tuwe wakweli, hakuna mtu anayeweka paneli moja tu ya jua kwenye paa lao. Kwa mfano, paneli moja ya jua inaweza kuzalisha karibu kWh 2 kwa siku. Kwa mfano, kwa wastani, nyumba moja hutumia karibu kWh 29 za umeme kwa siku. Kwa hiyo, unahitaji mengi zaidi ya jopo moja tu. Kwa kweli, utahitaji angalau paneli 15 za jua kwenye paa lako ili kuzalisha umeme wa kutosha kufunika matumizi yako ya kila siku ya nishati. Kwa mfano, kuna nguvu za jua za nguvu za nguvu za nguvu za nguvu za nguvu za nguvu za nguvu za nguvu za nguvu za nguvu za nguvu za nguvu za nguvu za nguvu za nguvu za nguvu za nguvu za nguvu za nguvu za nguvu za nguvu za nguvu za nguvu za nguvu. Mfumo wa 6 kW utatoa karibu 10,950 kWh kwa mwaka. Hiyo ni umeme wa kutosha kufunika matumizi ya umeme ya nyumba ya wastani na uwezekano wa kuondoa bili ya umeme ya 135. Idadi ya paneli za jua zinazohitajika inategemea kiasi cha nishati unachotumia kwa mwaka mzima. Lakini pia itategemea mazingira ya paneli yako na paneli wenyewe. Kuna mambo mengi yanayoathiri kiasi cha umeme unaozalishwa na paneli za jua, lakini kwa kweli, paneli za jua hazizalishi kiasi cha juu cha nishati inayowezekana. Maelezo ya paneli za jua, kama vile viwango vya pato la nguvu, huamuliwa kwa kujaribu paneli katika maabara chini ya Hali za Majaribio ya Kiwango. Paa lako si maabara hasa, na hali ambayo iko chini yake si daima kwenda kuwa bora kwa paneli yako ya jua. Kuna mambo kadhaa ambayo yanaweza kuathiri kiasi cha nishati ya jua ya umeme. Kiasi cha mwanga wa jua unaopiga paneli ya jua ni moja ya sababu kubwa katika jinsi umeme utakavyozalisha. Kadiri mwangaza wa jua ulivyo mwingi, ndivyo unavyoweza kutokeza umeme mwingi zaidi. Hii ina maana wewe itabidi kufunga paneli za jua juu ya sehemu unshaded ya paa yako. Hutaki matawi ya miti yanayoinuka au chemchemi yako ikitupa vivuli kwenye paneli zako. Hata vumbi na takwimu zinaweza kusababisha uzalishaji wa paneli zako kupungua, kwa hiyo ni muhimu kusafisha paneli zako za jua mara moja au mara mbili kwa mwaka. Ni zaidi ya tu kama paneli yako ni shaded au la. Pia ni muhimu kujua kama eneo unaloishi linapata mwangaza mwingi wa jua. Wanasayansi hutumia "saa za kilele cha jua" kulinganisha kiasi cha nuru ya jua ambayo maeneo tofauti hupata. Paneli za jua zitaweza kuzalisha umeme zaidi katika maeneo ambayo hupata saa nyingi za jua. "Tabula yafuatayo inaonyesha kiasi cha nishati ambacho jopo la 400W linaweza kuzalisha katika majimbo ambayo hupokea kiasi tofauti cha jua, ikidhani hali nyingine zote ni sawa: ""Nambari ya saa za kilele cha jua, uzalishaji wa umeme wa kila siku, na jinsi hali ya hewa inaathiri uzalishaji wa jopo la jua.""" Paneli za jua hutengenezwa na seli za jua, ambazo ni kile kinachogeuza mwanga wa jua kuwa umeme. Kwa sasa, paneli nyingi za jua hutumia seli za jua za monocrystalline, au seli za jua za silicon zenye ufanisi zaidi zilizotengenezwa leo. Kama wewe kutumika polycrystalline solar panel, ingekuwa si uwezo wa kuzalisha umeme kama mengi kama mwenzake monocrystalline. Si tu kuhusu nyenzo seli za jua ni kufanywa nje ya - kiasi cha umeme jopo inazalisha pia ni kuathiriwa na jinsi seli wengi kuna na jinsi seli hizo ni umbo! Paneli za jua kwa kawaida hutolewa katika ukubwa mbili: paneli za jua za seli 60 kwa nyumba na paneli za seli 72 kwa mitambo kubwa ya kibiashara. Paneli za 72 za solar zina uwezo wa kuzalisha umeme wa kutosha, lakini ni kubwa sana kwa ajili ya paa za makazi. Kwa mfano, kwa mfano, paneli za jua za 66-seli zinaweza kutumiwa kwa ajili ya nyumba, lakini kwa sababu ya kupanuliwa kwa paneli hizo, paneli hizo zinaweza kuzalisha nishati zaidi. Kwa mfano, paneli za jua za nusu-kupunguzwa zinatengenezwa kwa kutumia laser kabla ya kuingizwa kwenye paneli. Hii huongeza ufanisi wa jopo ili liweze kuzalisha umeme zaidi. Paneli za nusu-kupunguzwa pia zimeunganishwa tofauti na paneli za jadi, kwa hivyo kivuli kina athari ndogo kwa kiasi cha nishati inayotokezwa. Paneli za jua za Bi-Face: Paneli za jua za Bi-Face zinatengeneza umeme kutoka kwa mwanga unaopiga mbele na nyuma ya jopo. Wakati mwanga wa jua unapogonga ardhi na kurudi juu, paneli za bifacial zinaweza kukamata mwanga huo unaorudiwa na kuitumia kutengeneza umeme zaidi. Hizi si hasa muhimu kwa wamiliki wa nyumba na paa jua, lakini wanaweza kuwa chaguo kubwa kwa ajili ya mifumo ya ardhi-imewekwa. Ukweli ni kwamba, si paa zote zinazofaa kwa ajili ya nishati ya jua. Sehemu ya juu ya paa ni muhimu kwa jinsi paneli za jua zinavyoweza kuzalisha nishati kwa nyumba yako. Jambo la kwanza unalopaswa kuzingatia ni mwelekeo wa paa lako. Mwelekeo bora kwa paneli za jua kukabili ni kusini, hivyo unataka kuwa na paa kuelekea kusini kwa uzalishaji wa nishati ya juu. Hii haina maana huwezi kufunga paneli za jua kama paa yako inakabiliwa na mwelekeo tofauti. Paneli hizo zitazalisha umeme mdogo kwa sababu zitapata nuru kidogo ya jua. "Hii ni pamoja na: ""Uongo wa paneli ya jua"" - ""Uongo wa paneli ya jua"" - ""Uongo wa paneli ya jua"" - ""Uongo wa paneli ya jua"" - ""Uongo wa paneli ya jua"" - ""Uongo wa paneli ya jua"" - ""Uongo wa paneli ya jua"" - ""Uongo wa paneli ya jua"" - ""Uongo wa paneli ya jua"" - ""Uongo wa paneli ya jua"" - ""Uongo wa jua.""" Kadiri paneli za jua zinavyokuwa na umri, ndivyo zinavyopoteza uwezo wao wa kutokeza nishati. Unaweza kufikiria kama vifaa vingine vya elektroniki. Laptop yako yaweza kuwa haifanyi kazi kama ilivyokuwa siku ulipouinunua. Paneli za jua zinaharibika kwa kiwango cha wastani cha 0.5% kwa mwaka. Kwa hivyo, kwa mwisho wa kipindi cha kawaida cha dhamana ya miaka 25 ya jopo, kwa kawaida hufanya kazi kwa karibu 85% ya kile kilikuwa mwanzoni. Usiwe na wasiwasi <unk> paneli zako za jua bado zitazalisha umeme wa kutosha kusaidia kupunguza bili zako za matumizi. Jinsi ya kuamua kiasi cha umeme ambacho jopo la jua linaweza kuzalisha Sasa, kwa kuwa tumefunika nini kinaathiri uwezo wa jopo la jua kuzalisha umeme, tunaweza kuingia katika vitu vizuri. Kujua jinsi paneli za jua zinaweza kuzalisha nishati kwa nyumba yako Tumekuwa tayari imara kwamba kuna idadi ya mambo ambayo ni kwenda kuathiri jinsi paneli yako ya jua kuzalisha umeme.

Ni betri ngapi za 1000W? Siku hizi, tofauti mbalimbali za nguvu zinapatikana kwa ajili ya betri za mfumo wa jua. Mwaka 1883 Charles Fritts wa Marekani alitengeneza seli ya kwanza ya jua kwa kutumia seleniamu. Wakati huo, hakuna mtu aliyefikiri kwamba teknolojia hiyo ingefanikiwa sana wakati ujao. Hata hivyo, watu wengi zaidi na zaidi wanageukia teknolojia ya jua. Ikiwa una mpango wa kufanya hivyo, ni uamuzi wa maisha yako yote. Kwa mfano, unaweza kuamua kiwango cha umeme unaohitajiwa kwa mfumo wa jua wa 1000W, kiwango cha umeme unaohitajiwa kwa mfumo wa jua wa 2KW, na kiwango cha umeme unaohitajiwa kwa mfumo wa jua wa 1000W. Betri za Jua Ni Nini? Batri za jua ni vifaa vya kuhifadhi umeme wa ziada unaotokana na paneli za jua. Nishati hii iliyohifadhiwa hutumiwa na mfumo wa jua kuendesha nyumba yako, umeme, au vifaa vingine vinavyounganishwa nayo. Ni betri ngapi zinahitajika kwa mfumo wa jua wa Watt 1000? Mfumo wa paneli za jua za 1000-W ni aina ya kawaida ya mifumo ya nishati ya jua inayopatikana sokoni. Mifumo ya paneli za jua inategemea jua, lakini ikiwa unataka kuendesha siku zenye mawingu, utahitaji betri ili kuzipa nguvu. Sasa swali lako la pili ni, ni betri ngapi zinahitajika kwa mfumo wa jua wa watt 1000? Kwa kweli, inategemea. Bateria moja ya risasi ya 200Ah inaweza kuendesha mfumo wa jua wa 1000W kwa saa moja, na betri kubwa zinaweza hata kuendesha mifumo kama hiyo kwa muda mrefu. Ikiwa paneli yako ya jua ina voltage sahihi, hata betri ya 24V inaweza kutumika. Kwa mfano, betri ya lithiamu ya 12V 100Ah inaweza kutoa nguvu ya watt 2400 ikiwa imefungwa kabisa, lakini inaweza tu kupata nguvu ya watt 1200 kwa sababu ya kutolewa kwa kina cha 50%. Kwa mfano, kuna betri za 12V ambazo zina uwezo wa kutengeneza umeme wa watt chache. 100Ah, 300Ah, 300Ah, 300Ah, 300Ah, 300Ah, 400Ah, 400Ah, 400Ah, 400Ah, 400Ah, 400Ah, 400Ah, 400Ah, 400Ah, 400Ah, 400Ah, 400Ah, 400Ah, 400Ah, 400Ah, 400Ah, 400Ah, 400Ah, 400Ah, 400Ah, 400Ah, 400Ah, 400Ah, 400Ah, 400Ah, 400Ah, 400Ah, 400Ah, 400Ah, 400Ah, 400Ah, 400Ah, 400Ah, 400Ah, 400Ah, 400Ah, 400Ah, 400Ah, 400Ah, 400Ah. Tofauti ni tu katika muda wa ugavi. Kwa mfano, betri ya 300ah na DOD ya 50% ina watts 1800 zinazotumika, ambayo ni nzuri kwa saa moja na nusu au labda saa moja na dakika 45. Kwa upande mwingine, ikiwa una betri mbili za 250ah, basi unaweza kutumia betri ya 500ah. Hata na nguvu ya watts 3000 tu, betri inaweza kubeba mzigo wa watts 1000 kwa masaa matatu. Kwa mfano, unaweza kuwa na wazo la kuunda betri ya 1000W kwa mfumo wa jua. Ni Paneli ngapi za jua za 1000W?

"Corporate Park, D-21, Sekta 21, Dwarka, Delhi, India, 11777 ""Ni ukubwa gani wa inverter ya jua ninayohitaji?""" Inverters jua ni moja ya vipengele muhimu zaidi ya mfumo wa jopo la jua. Wao ni wajibu wa kubadilisha moja kwa moja sasa (DC) umeme kutoka paneli yako ya jua kwa umeme wa mzunguko (AC) umeme kwa nguvu vifaa vyako. Wakati wa kubuni mfumo wako wa paneli za jua, ukubwa wa inverter yako utacheza jukumu muhimu katika uzalishaji wa umeme. Katika makala hii, tutazungumzia nini athari za ukubwa wa inverter ya jua. Jinsi ya kuamua ukubwa wa inverter Inverter za jua huja katika ukubwa wote tofauti, kubwa na ndogo. Sawa na paneli za jua, ukubwa wa inverter unaweza kupimwa katika watts (W). Kwa upande wa ukubwa wa inverter ya jua, wataalamu wa mitambo ya jua huamua juu ya mambo matatu muhimu: ukubwa wa mfumo wako wa jua, eneo lako, na hali maalum ya eneo. Ukubwa wa solar array ni muhimu sana katika kuamua ukubwa unaofaa kwa inverter yako. Inverter ya jua inabadilisha umeme wa DC kutoka kwa safu ya umeme, na inahitaji uwezo wa kushughulikia nguvu zote zinazozalishwa na safu ya umeme. Kwa kawaida, ukubwa wa inverter yako inapaswa kuwa sawa na kiwango cha DC cha mfumo wako wa jopo la jua; ikiwa unaweka mfumo wa kilowatt 6 (kW), unaweza kutarajia inverter iliyopendekezwa kuwa karibu 6000W, pamoja na au chini ya asilimia ndogo. Inverter wazalishaji kawaida orodha ukubwa miongozo kwa ajili ya uwezo safu yao inverters inaweza kuwa paired na juu ya karatasi zao bidhaa spec. Ikiwa ukubwa wa safu ya jua iliyounganishwa na inverter yao ni nje ya miongozo iliyotajwa, watengenezaji wanaweza kufuta matoleo yao ya dhamana. Jiografia pia ina jukumu muhimu katika ukubwa wa inverter yako ya jua kutokana na athari zake kwa uzalishaji wa mfumo wako wa jopo la jua. Mali katika Arizona kuwa na juu ya jua irradiances (yaani. Kwa mfano, katika eneo la Arizona, mfumo wa paa wa kilowati 6 (kW) unapaswa kuzalisha nguvu zaidi kuliko mfumo wa ukubwa sawa kaskazini. Kwa sababu mifumo hii miwili itazalisha kiasi tofauti cha umeme wa DC wakati fulani, inverters zinazohitajika kushughulikia mzigo huo wa umeme pia zinaweza kuwa na ukubwa tofauti. Katika maeneo yenye jua zaidi na joto la wastani, inverters itakuwa ukubwa karibu na jumla ya watts ya safu ya jua ili iweze kushughulikia karibu na pato la nguvu ya juu ya safu katika hatua yoyote. Vinginevyo, ikiwa safu yako ya jua inakabiliwa na kiasi kidogo cha mionzi ya jua au joto la juu ambalo hupunguza ufanisi wa jopo, ni uwezekano mdogo wa kuzalisha pato hilo la nguvu ya juu iliyofafanuliwa na kiwango cha DC chini ya hali ya kawaida ya majaribio (STC). Katika hali hizi, ndogo, underdimended inverter inaweza kupata kazi kufanyika. Mahali na muundo maalum wa safu yako ya jua utaathiri ukubwa wa inverter yako ya jua. Kama ilivyo kwa jiografia, mwinuko na azimuth ya safu yako ya jua itaathiri kiasi cha umeme mfumo unaweza kuzalisha. Mambo ya mazingira (kama vile shading, vumbi, nk) Pia, ina jukumu kubwa katika jinsi jua linavyofikia safu. Wauzaji wa jua watazingatia mambo haya, ufanisi wa vifaa, na zaidi wakati wa kukadiria uzalishaji wa jumla wa mfumo wako wa jopo la jua. Kwa ujumla, kiwango cha chini cha kiwango cha chini cha kiwango cha chini cha kiwango cha chini cha kiwango cha chini cha kiwango cha chini cha kiwango cha chini cha kiwango cha chini cha kiwango cha chini cha kiwango cha chini cha kiwango cha chini cha kiwango cha chini cha kiwango cha chini cha kiwango cha chini cha kiwango cha chini cha kiwango cha chini cha kiwango cha chini cha kiwango cha chini cha kiwango cha chini cha kiwango cha chini cha kiwango cha chini. Mifumo ya paneli za jua ambayo hupata kivuli zaidi, iko kwenye mwinuko wa chini, au inakabili mashariki badala ya kusini, ina sababu za juu za kupungua kuliko mifumo kwenye paa zenye jua, zinazoelekea kusini. Mifumo ya paneli za jua na sababu za juu za derating hazitafikia pato lao la juu la nishati na kama vile inaweza kumudu uwezo mdogo wa inverter ikilinganishwa na ukubwa wa safu. Inverter ya jua inaweza kuwa kubwa au ndogo kuliko kiwango cha DC ya safu yako ya jua. Kiwango cha inverter ya mfumo wa paneli ya jua ni kiwango cha DC cha safu yako ya jua, kugawanywa na pato la juu la AC ya inverter yako. Kwa mfano, ikiwa mfululizo wako ni 6 kW na inverter ya 6000 W, uwiano wa mfululizo kwa inverter ni 1. Ikiwa unaweka safu ya ukubwa sawa na inverter 5000, uwiano ni 1.2. Kwa mfano, kiwango cha kiwango cha kiwango cha kiwango cha kiwango cha kiwango cha kiwango cha kiwango cha kiwango cha kiwango cha kiwango cha kiwango cha kiwango cha kiwango cha kiwango cha kiwango cha kiwango cha kiwango cha kiwango cha kiwango cha kiwango cha kiwango cha kiwango cha kiwango cha kiwango cha kiwango cha kiwango cha kiwango cha kiwango cha kiwango cha kiwango cha kiwango cha kiwango cha kiwango cha kiwango cha kiwango cha kiwango cha kiwango cha kiwango cha kiwango cha kiwango cha kiwango cha kiwango. Chini ni baadhi ya mifano ya bidhaa za inverter ya jua na mapendekezo yao ya pato la nguvu ya juu ya DC: Sunny Boy 5.0 - Uwiano wa juu wa mfululizo kwa inverter inaweza kufanya kazi kwa mfumo wako ikiwa paneli zako za jua hazitazalisha kwa pato lao la nguvu ya juu kwa sababu ya sababu zilizotajwa hapo juu. Faida ya oversizing yako solar array kuhusiana na inverter uwezo ni kwamba chini-wattage inverters itakuwa nafuu kuliko wenzao kubwa. Lakini si vyema oversize safu yako sana kama inaweza kusababisha clipping. Kupunguza: Kupunguza hutokea wakati paneli zako za jua zinazalisha DC nyingi sana kwa inverter kushughulikia wakati fulani. Wakati hii hutokea, inverter itapunguza kiasi cha nishati ni kubadilisha, na kusababisha hasara ya nguvu kutoka kwa mfumo wako wa jopo la jua. Kwa upande mwingine, hutaki kufunga inverter ya jua ambayo ni kubwa sana (yaani. ina chini ya safu-kwa-inverter uwiano) kwa sababu inverter yako ni kwenda kuwa ufanisi zaidi kama ni mbio karibu na uwezo wake wa jumla. Kama inverter ni kubwa sana ikilinganishwa na safu, haitazalisha kiasi kinachohitajika cha umeme. Vipi kuhusu inverter ndogo-ndogo? Katika microinverters. Mabadiliko ya umeme kutoka DC kwa AC hutokea katika kila jopo moja. Microinverters ni ndogo kuliko inverters kubwa ya kati wakfu kwa kushughulikia nguvu kwa ajili ya mfumo mzima. Kama vile, ukubwa wa microinverter inalingana na pato la nishati ya jopo la jua ni kubadilisha nguvu kwa badala ya DC rating ya mfumo mzima. Kama ilivyo kwa inverter ya kati, watengenezaji wa microinverter wataorodhesha miongozo kuhusu kiwango cha juu cha DC ambacho jopo linapaswa kuwa nacho ikiwa limeunganishwa na bidhaa yao ya microinverter. Kama wewe kuunganisha juu ya watt panel kuliko microinverter specifikationer kuonyesha, basi clipping kitatokea.
