Solar Controller FAQ

  1. 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.

  2. 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.
  3. 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.
