Observe correct polarity at all times. Any contact in reverse polarity, however
brief, will cause the regulator and/or inverter fuse to blow and may damage the unit.
1.3 Tools Required (Additional tools may be required)
a. Slot Screwdriver
b. # 2 Robertson Square Head Screwdriver
c. Keyhole saw
d. Punch or Awl
e. Pliers
f. Wire Strippers
2.0 Wiring the Solar Module and Power Cable
1. Remove the module’s Junction Box cover. Remove the knockout on the Junction
Box for the connector and power cable. In some cases the connector may have
already been factory installed. To remove the knockout on the Junction Box, hold a
screwdriver tip against the knockout and strike sharply.
2. Strip back 2” of sheathing from the power cable. Insert the stripped back end of the
power cable through the connector and into the junction box. Secure the black wire
under the screw on the positive terminal, and the white wire under the negative
terminal. If the power cable consits of red and black wire, then the red is positive
and the black is negative. Ensure that all the wiring connections are tight. Replace
the Junction Box cover.
The RV-10 and RV-20 Modules are covered by a 5-year limited warranty.
3.0 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.
3.1 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.
3.2 Method 2 – Through Screen Grid
1. Thread the power cable (already wired to the 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 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.
4.0 Mounting the Solar Module
Cover the entire module with opaque material to prevent the danger of shock during
installation. Do not remove the material until the installation is complete. The solar
modules may be mounted to the roof using the included mounting feet.
g. Wire crimpers
h. Electric hand drill
i. 1/16 and 3/8 inch drill bit
j. 5/16 and 7/16 inch wrench
k. Sealant
Caution:
