3.1 WIRING DIAGRAM
The GP-SB-PWM Maximum 37.5A rating is based on a 30-amp total maximum short circuit current rating (Isc) from the parallel solar panels nameplate
ratings. The National Electric Code species the PV equipment/system rating to be 125% of the maximum Isc from the solar panels nameplate ratings
(1.25 times 30 = 37.5A).
Use the wiring diagram (below) to connect your battery to the battery terminals on the solar controller. First, connect the battery to the controller,
and then connect the solar panel connection to the controller.
The fuse or breaker used should be no larger than the amperage of the solar controller. (10A fuse for a 10A controller / 30A fuse for
a 30A controller)
WARNING: When a ground fault is indicated, battery terminals and connected circuits might be ungrounded and hazardous.
CAUTION: Risk of Electric Shock: When the photovoltaic array is exposed to light, it supplies a DC voltage to this equipment
CAUTION: Internal Temperature Compensation: RISK OF FIRE, USE WITHIN 3 meters of BATTERIES.
The fuse or breaker should be installed no more than 18 inches from the battery connection.
