1. Locate the refrigerator vent on the roof of the RV. Remove vent cover to gain access to the duct opening.
 

2. Thread 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-RVC-30-MPPT 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.
