CHARGE CONTROLLERS

The brain of your solar system. Maximize every watt and protect your batteries.

Your charge controller regulates voltage and current between panels and batteries. MPPT controllers are ~30% more efficient — go MPPT for systems over 200W. PWM controllers are cheaper, fine for small setups.
