A Solar Controller is an essential component of your photovoltaic (PV) system. The Controller 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 a 12 volt surface mounted photovoltaic (PV) charge controller rated for a continuous solar current input of 30 amps.
