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-10 is a 12 volt surface mounted
photovoltaic (PV) charge controller rated for a continuous
solar current input of 10 amps.
