PWM and MPPT charge controllers are both devices widely used to charge batteries using energy produced by solar panels on campers and boats and, of course, in fixed installations.
The PWM controller is a switch connecting the solar panels to your service battery. This device can substantially reduce the voltage of the meetings until it reaches that of the battery bank.
The MPPT controller, on the other hand, is more sophisticated (and more expensive): it regulates its input voltage to harvest the maximum possible power from the solar panels. [Read more…] about Best MPPT or PWM solar controller for the camper
