© 2019 Go Power!
Congratulations, your GP-PWM-30-SB should now be operational. If the
battery power is low and the solar array is producing power, your battery
should begin to charge.
7. Re-torque:
After 30 days of operation, re-torque all terminal
screws to ensure the wires are properly secured to the controller.
WARNING:
This unit is not provided with a GFDI device. This
charge controller must be used with an external GFDI device as
required by Article 690 of the National Electric Code for the
installation location.
6.0 Wiring Diagram
IMPORTANT:
This diagram is valid only for version 1.5 and newer.
Version 1.4 and older have different terminal locations.
The GP-PWM-30-SB Maximum 37.5A rating is based on a 30 amp total
maximum short circuit current rating (Isc) from the parallel solar modules
nameplate ratings. The National Electric Code specifies the PV
equipment/system rating to be 125% of the maximum Isc from the PV
module 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 to the controller.
The fuse or breaker used should be no larger than 50 amps.
The controller will not work unless there is a battery
connected to the battery terminals with at least 9V.
WARNING:
When the photovoltaic (solar) array is exposed to
light, it supplies a dc voltage to this equipment
