Overview & Specifications
A Solar Controller (or Charge Controller / Regulator) maintains the life of the battery by protecting it from overcharging. When your battery has reached a 100% state of charge, the controller prevents overcharging by limiting the current flowing into the batteries from your solar array. The GP-PWM-30-SQ is rated for a continuous solar current input of 30 amps, uses Pulse Width Modulation (PWM) technology and a unique four stage charging system that includes an optional equalize setting to charge and protect your battery bank.
