WIRING DIAGRAMS
7.1 CHARGING ONLY ONE BATTERY
Use the following wiring diagram if you are using the GP-PWM-30-UL to charge only one battery. Connect your battery to the battery
1 terminals on the solar controller.
The controller will not work unless there is a battery connected to the Battery 1 terminals.
WARNING: When the photovoltaic (solar) array is exposed to light, it supplies a dc voltage to this equipment.
7.2 CHARGING TWO BATTERIES
Use the following wiring diagram if you are using the GP-PWM-30-UL to charge two separate battery banks. Connect battery bank 1
to the battery 1 terminals and battery bank 2 to the battery 2 terminals on the back of the solar controller.
IMPORTANT: Ensure your primary/permanent battery (house bank) is connected to the battery 1 terminals. Connect your secondary
battery to battery 2 terminals only. Your permanent battery (battery 1) will receive the full current rst. Once battery 1 is fully charged,
current will be available to charge battery 2.
The controller will not work unless there is a battery connected to the battery 1 terminals.
