Connecting BMS to charge controller and load
When your energy source is a solar panel, the constant current is not constant, as it depends on how much current your panel delivers.
This way, the &quot;constant current - constant voltage&quot; charging algorithm transforms into &quot;limited current - limited voltage&quot; charging. Batteries are generally OK with this, as long as your BMS behaves.
The load will subtract from the available charging current and it is up to you to get large enough solar panel if you want the batteries to be fully charged at the end of the day.
