MY TRAVEL TRAILER IS PREWIRED FOR SOLAR, NOW WHAT?
PRE WIRE FOR SOLAR RVS MAY REQUIRE A DIFFERENT BASE SOLAR KIT AS THE WIRING DONE AT THE FACTORY IS NOT ALWAYS OPTIMIZED FOR THE RETAIL KITS.
Air Airstream travel trailers were some of the first RVs to include prewired for solar. There are many sizes of panels that will work with the prewired RVs. Our Go Power solar kits are designed to pair with the prewired solar wiring on these travel trailers. These prewired solar trailers can come in a couple of different configurations. The cable entry plate is sometimes at one end of the trailer or motorhome and after additional equipment is installed, the ideal solar panel location is across the entire roof.
SOLAR TIP: look at manuals for your RV and see what the manufacturer would have installed if you had purchsed the RV with panels

CABLE ENTRY PLATE MAKES WIRING EASY FOR RV ROOF SOLAR
Many of these travel trailers are using the Go Power cable entry plate on the RV roof. These cable entry plates make hooking up a Go Power solar kit a breeze. All that is left is mounting the panels, fusing the wire and installing the charge controller. Most of the hard work of running cables has already been completed by the factory.
This can save as many as 5 hours off a standard install of solar panels on your travel trailer, fifth wheel, camper or motorhome. Not all of the prewired RVs use these cable entry plates, but instead, use 2 MC-4 wires terminating through the roof.
** CHARGE CONTROLLER PREWIRED FOR SOLAR STICKER ALERT ** Many of the prewired RVs have a sticker that looks like a charge controller. It is usually help in locating placement for the controller and locating the solar cables coming in from the roof.
The newer option is for some Trailers to come prewired with the circuit completed from the cable entry plate through a charge controller and completed at the battery. This is more rare of an install an often uses an SQ designated charge controller.
The charge controller below is the Go Power PWM 30 model that is designed for the prewired solar kits. The Prewired For Solar sticker will most likely resemble this device and sometimes is even a template.

Depending on which travel trailer make and model you have will determine which type of panel is best for your needs.
