QuickStart Setup
Step 1: Check your order to make sure that all parts are included. For the 300 watt kit, this is three 100 watt so-
lar panels, three 10-amp inline fuses, two pairs of MC4 T-branch connectors, a pair of 15-foot MC4-to-MC4
cables, a red/black 6” MC4-to-bare cable pair, a 5-foot (10 AWG) red/black bare-wire-to-ring-lug cable
pair (charge-controller-to-battery), a 5-foot (4 AWG) red/black cable pair (battery-to-inverter), a Grape So-
lar PurePower 1800 inverter, and a GS-PWM-COMET-40 charge controller.
Step 2: For optimum output, place the panels so they are facing due south at approximately the same angle as
your latitude, in full sun. If you are connecting the system during daylight, cover the panel with cardboard,
cloth, or a similar option so that it does not output power. Place the panel so it is facing due south at approx-
imately the same angle as your latitude, in full sun.

QuickStart Setup
Step 4: Use the 10 awg 5-foot red & black cable pair to connect your positive and negative battery terminals to
the “Battery Positive” (use red cable from the positive battery terminal) and “Battery Negative” (use black
cable from the negative battery terminal) inputs of the charge controller (the center set of terminals).
Step 3: Mount controller if desired (note that it must be in a NEMA-4 rated enclosure if it is outdoors).

If your battery has sufficient charge (11.5 volts or more), you should now see the controller’s LCD display
activate. This means the controller has power (controllers are powered by the battery, not the panels).

Step 6: Connect the MC4 outputs of the T-branch connectors to the 15-foot MC4 extension cables.
Step 5: Connect the positive panel leads to the inline fuses. Then connect the positive and negative outputs of
the panel to the appropriate T-branch connectors, as seen at the top of the next page. Panels 2 and 3 connect
to the 1st pair, and the outputs of that 1st pair along with Panel 1’s outputs connect to the second pair.

Then connect the MC4 outputs of the 15-foot cables to the 6” MC4-to-bare wire pair as shown below:
Step 7: Connect the bare wire end of the red cable to the “PV Positive” input of the controller, and the black
cable end to the “PV Negative” input (the left hand set of terminals).

Step 8: Connect the 4 awg red (positive) and black (negative) 5-foot cables from battery to inverter
Step 9: Uncover the panel. As the day progresses, you should see the battery voltage slowly increase,
eventually the controller display will read “Float”. At this point the battery can be used to pro-
vide power (turn the inverter on and plug your AC devices into it for power).
