Mount the 100-watt solar panels  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.
Connect the bare wire end of the 10 AWG red battery
cable  to the (+) battery terminal on the bottom of the
Comet-40 charge controller . Connect the bare wire
end of the 10 AWG black cable  to the (-) battery ter-
minal. A Phillips head screwdriver can be used to loos-
en and tighten the screw clamps onto the wires.
Attach the ring lug end of the red cable  to the positive
terminal of a 12V deep cycle battery. Attach the ring lug
end of the black cables  to the negative terminal of the
battery.
The charge controller  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 con-
troller, which regulates solar power flow to the battery, is
powered by the battery.
