- Screwdriver– Philips Head
- Wire Stripper/Cutter
- 12-Volt Deep-Cycle Battery Bank
- Voltmeter (for Troubleshooting)
Mount the 50-watt solar panel 5 so that it is facing due South at approximately the same angle as your latitude. The ideal area has full sun and no shading. If the following connections are made during daylight, cover the panel with cardboard, cloth, or a similar opaque material so that the panel does not output power.
Connect the wire end of the red battery cable 4 to the “+BATTERY” terminal on
the back of the GS-PWM-20A charge controller 1. Connect the wire end of the
5-foot black cable 3 to the “-BATTERY” terminal. A Phillips head screwdriver
can be used to loosen and tighten the screw clamps onto the wires.
Attach the ring lug end of the red cable 2 to the positive terminal of a 12V
deep cycle battery. Attach the ring lug end of the black cable 3 to the
negative terminal.
Using wire cutters, snip the 10-gauge, 15ft. MC4 extension cable 4 into two equal halves (7.5ft each.) On the cut ends, strip off ¼-inch of insulation, revealing bare wire.
Connect the MC4 ends of the halved cable 4 to the compatible MC4 ends of the
solar panel 5 cables.
(Mark the end of the positive panel cable with a piece of tape to help
distinguish polarity during connection.)
Connect the bare wire end of the positive cable 4 to the “SOLAR +” input of the charge controller 1 . Connect the negative bare end to the “SOLAR -” input. Now, you can mount the GS-PWM-20A charge controller to an indoor wall or within a NEMA-3R rated enclosure.
Remove the panel covering. In good sunlight, the charge controller’s 1 ”BAT %” should increase to 100%. Once the battery is fully charged and the controller is set to “LOAD ON,” the system will provide power through the load control output or through the two USB ports. If an inverter is added to the system, it must be connected to the battery bank, and not to the charge controller.
