If you were to get a 20a pwm controller you would be able to regulate a solar panel bank of up to 320w for 12v batteries and 640w for 24v batteries the pwm controller can also be used to connect solar panels to a battery bank of 12v batteries provided that the batteries are the same size and that they are in good condition.
Innogear solar panel charge controller.
A solar charge controller is designed to receive power from a solar panel or array of panels and use it to charge a battery or bank of batteries.
Connecting the solar panel charge controller mppt or pwm are the same solar battery and the pv array in the right way is the essential work before enjoying the solar energy.
