How to increase watts going to my lithium battery?
In comment, you provided the following charge characteristics:

Charging Current: &lt;10 Amps Charging Voltage: 58.8 Volts 

58.8 volts times 10 amps sets an absolute charging power limit of 588 watts.

You cannot exceed this without exceeding the data sheet limits, and that is A Bad Thing.

In order to do this, you will need at least 4 160-watt solar panels, since 3 times 160 watts is 480 watts. Plus, your MPPT will not be 100% efficient, so you need to keep that in mind.

You will also need a better charger - one which can provide a charge current of 10 amps at 58 volts, or about 580 watts.
