Solar Controller FAQ
-
What does a solar controller do?
A charge controller or charge regulator is basically a voltage and/or current regulator to keep batteries from overcharging. It regulates the voltage and current coming from the solar panels going to the battery.
-
What are the two types of solar controllers?The two major types of solar charge controllers are:
- Pulse Width Modulation (PWM) controllers.
- Maximum Power Point Tracking (MPPT) controllers.
-
Can I use solar without controller?
Using a solar module for low current maintenance charging can be done safely without a charge controller as long as the solar panel output is <1% of the battery capacity.
