4. Install the connector for the power cable in the Junction Box. Secure the red wire
under the screw for the positive terminal, and the black wire under the negative
terminal. Ensure that all the wiring connections are tight. Install the interconnect
cable between the modules as shown in the wiring diagrams. Make sure the red
wires are secured under the positive terminals, and the black wires are secured
under the negative terminals. Ensure that all wiring connections are tight. Replace
the Junction Box covers.
5. Expander Kits for modules with two junction boxes will have a single red wire
connecting the two positive junction boxes together and a single black wire connecting
the two negative junction boxes together. The Power Cable will then be connected
to the positive and negative junction box of one of the modules.
6. Continue to Section 4, “Routing the Power Cable through the Fridge Vent”.
3.0 Wiring A Single Solar Module With MC Cables
RV Kits containing a single module with MC cables will be equipped with an MC power
cable. All connections will be tagged either positive or negative. Plug in the appropriate
connections. Refer to Diagram-3, “MC Connections for 1-2 Modules”.
3.1 Wiring Two Solar Modules In Parallel with MC Cables
RV Kits containing two modules with MC cables will be equipped with an MC power
cable, a negative MC parallel cable, and a positive MC parallel cable. All connections
will be tagged either positive or negative. Plug in the appropriate connections. Refer to
Diagram-3, “MC Connections for 1-2 Modules”.
3.2 Modules with MC Connectors Wired to a Non-Potted Junction Box
Please be aware that some modules are equipped with MC cables and a fully functioning
non-potted Junction Box. In this case, the MC cables may be ignored and the Junction
box may be wired normally. The MC cables may be removed or left in place as long as
they do not impede the installation process. Do not connect the positive and negative
MC cables from the same junction box together; this will short circuit the module.
4.0 Routing Power Cable through the Fridge Vent
Locate the refrigerator vent on the roof of the RV. Remove vent cover to gain access to
the duct opening. Refer to Figure 1. Retain vent-fastening hardware.
4.1 Method 1 – Hole in Side of Vent
Drill a hole through the side of the vent (5/8” hole). Insert a rubber grommet (not
included) into the hole. Insert the power cable (already wired to the solar module)
through the hole and carefully route it to the battery. Be certain to leave enough slack
to allow cable routing from module to vent along desired path.
4.2 Method 2 – Through Screen Grid
1. Thread power cable (already wired to solar module) carefully through the screen
and into opening. Enlarge screen grid hole if necessary.
2. Avoid strapping the power cable to existing wire between the module and the battery.
Allowing a few inches of space between the power cable and existing wire will
lessen the chance of voltage loss through thermal conduction. Use cable clamps
with the # 6 self-tapping screw and/or tie wraps every few feet along RV roof and
interior route to battery.
3. Ensure all penetrations into the RV roof are watertight. Use an appropriate sealant
as recommended by your RV Dealer to seal holes wherever necessary.
4. Replace vent cover.
5.0 Mounting the Solar Module
Cover the entire module with paper to prevent the danger of shock during installation.
Do not remove the paper until the installation is complete.
Caution:
On contact, uncured adhesive/
sealant may irritate eyes. In the
event of contact, flush eyes with
water and consult a physician
immediately.
