  1. GS-PWM-Comet40 Charge Controller
  2. 3x GS- STAR-100W Solar Panel
  3. 3x 15-Amp MC4 In-Line Fuse
  4. 2x MC4 Branch Connector Set
  5. 5-ft. Red/Black 10 AWG Cable Pair
  6. 15-ft. MC4 to Bare Cable Pair

Additional tools and equipment you will need:

  • Screwdriver– Philips Head
  • 2-Volt Deep-Cycle Battery Bank

2. Mount the 100-watt solar panels (2) so that they are 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 panels with cardboard, cloth, or a similar opaque material so that the panel does not output power.

3. Connect the bare wire end of the 10 AWG red battery cable (5) to the (+) battery terminal on the bottom of the Comet40 charge controller (1). Connect the bare wire end of the 10 AWG black cable (5) 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 (5) to the positive terminal of a 12V deep cycle battery. Attach the ring lug end of the black cables (5) to the negative terminal of the battery.

The charge controller (1) display screen will be visible if the battery has sufficient charge. If the display screen is not visible, the battery must be charged from an another source before processing solar power. The charge controller, which regulates solar power flow to the battery, is powered by the battery.

4. Branch connector sets (4) are typically clipped together when shipped. Un clip the branch connectors until there are 4 separate units.

Connect one branch connector (4) with the “female” output to the “male” end of a 15-ft. MC4-to-Bare-Wire cable (6). Connect an addi-tional “female” output branch connector (4) to the attached branch connector.

5. With the other 15-ft MC4-to-Bare-Wire cable (6), con-nect one branch connector (4) with the “male” out-put to the “female” end of the cable. Connect an ad-ditional “male” output branch connector (3) to the attached branch connector.

Now, attach an in-line fuse (2) to each of the “female” inputs.

7. Connect the bare-wire ends of the MC4-to-Bare Wire pair (6) to the charge controller (1).
The positive wire connects to the (+) input and the negative wire connects to the (-) input.

8. Remove the panel covering. In good sunlight, the charge controller’s (1) ”BAT %” should increase to 100%. When the controller is set to “LOAD ON,” the system will provide power through the load control output or through the USB port.
