Wiring Diagram
6.2 Charging Two Batteries
Use the wiring diagram on the next page if you are using the GP-PWM-30 to charge
two batteries. First, connect battery 1 to the battery 1 terminals and battery 2 to the
battery 2 terminals on the back of the solar controller. Then, connect the solar panel
to the controller.
IMPORTANT: Ensure your primary/permanent battery (house bank) is connected to
the battery 1 terminals. Connect your secondary battery (starting, trolling) to battery
2terminalsonly.Yourpermanentbattery(battery1)willreceivethefullcurrentrst.
Once battery 1 is fully charged, the full current will be available to charge battery 2.
The controller will not work unless there is a battery connected to the
battery 1 terminals.
