WIRING
Wiring From Solar Panel to Charge Controller
1. Determine the position of the solar panel on the RV roof. While positioning panels, avoid shading of the
solar panel by neighbouring obstacles such as vents, air-conditioners, TV antennas etc. As far as possible,
position the panels to minimize wiring distance between the solar panel and the Charge Controller.
Place the panel at least 8-10 inches away from the RV roof edges and leave sufficient space to walk
around the panel and access the mounting hardware.
2. Make sure the thickness of the roof at the installation location is at least ½” thick and the material
is strong enough to provide mechanical support to the solar panel and mounting hardware against
possible wind loading. Place the panel length-wise to reduce the effects of wind loading on the RV.

3. Solar Panel Connecting Wires kit "SCW-20-2" consisting of 2 pre-assembled, 20 ft, AWG #12, Positive
(+) & Negative (-) PV extension wires have been provided (see Fig. 8.4). The wires have MC4 mating
connectors on one end for connecting to the solar panel & bare ends on the other side for connecting
to the Charge Controller. The wires are marked (+) & and (-) for identification of the polarity.
