Do solar panels need a PWM charge controller?

PWM (pulse-width modulation) charge controllers depend on older, less reliable hardware and enable you to adjust the solar panel’s voltage to the battery voltage. E.g., if you were to run a nominal 12-volt solar panel through a PWM charging controller, you need a 12-volt battery bank.

Can a solar charge controller be used on a 120V battery?

A select few, such as the Victron 150V range, can be used on all battery voltages from 12V to 48V. Several high-voltage solar charge controllers, such as those from AERL and IMARK, can be used on 120V battery banks. Besides the current (A) rating, the battery voltage also limits the maximum solar array size connected to a solar charge controller.

Can I use a MPPT charge controller with a solar module?

Because MPPT charge controllers can handle a higher input voltage from the solar module array than the battery bank's voltage, you can also use these charge controllers with solar modules that have voltages that don't match your typical system voltage (i.e. 12, 24 or 48V).
