INSTALLATION
4.3 REFRIGERATOR VENT ACCESS
OPTION 1
1. Locate the refrigerator vent on the roof of the RV. Remove
vent cover to gain access to the duct opening.
2. Drill a hole through the side of the vent (5/8” hole).
3. Remove any sharp edges from the hole.
4. Insert a rubber grommet (not included) into the hole.
5. Insert the MC4 Positive and Negative Extension Cables
through the hole and carefully route it to the GP-PWM-10
solar charge controller. Be certain to leave enough slack to
allow cable routing from module to vent along desired path.
6. Use cable clamps with the #6 self-tapping screw and/or
tie wraps every few feet along RV roof and interior route
to GP-PWM-10.
7. Ensure all penetrations into the RV roof are watertight. Use
an appropriate sealant as recommended by your RV Dealer
to seal holes wherever necessary.
8. Replace vent cover.
4.4 REFRIGERATOR VENT ACCESS
OPTION 2
1. Locate the refrigerator vent on the roof of the RV. Remove
vent cover to gain access to the duct opening.
2. Thread the MC4 Positive and Negative Extension Cables
carefully through the screen and into opening.
3. Enlarge screen grid hole if necessary
4. Remove any sharp edges from the hole.
5. 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.
6. Use cable clamps with the # 6 self-tapping screw and/or
tie wraps every few feet along RV roof and interior route to
the GP-PWM-10 solar charge controller.
7. Ensure all penetrations into the RV roof are watertight. Use
an appropriate sealant as recommended by your RV Dealer
to seal holes wherever necessary.
8. Replace vent cover.
4.5 CABLE ENTRY PLATE - OPTION 3
1. Remove the rubber sealing caps from the ends of the MC4
connectors in the CEP.
2. Plug the Positive and Negative MC4 Connectors from the
solar panels directly into the CEP.
3. Locate the positive and negative cables exiting the CEP
and route these to the GP-PWM-10 solar charge controller.
