My Fifth Wheel Camper Came Prewired With Solar on the Roof and Side Now What

My Fifth Wheel Camper Came Prewired With Solar on the Roof and Side Now What

A lot of people ask the question of what exactly does it mean to have pre-wire done on the roof of a 5th wheel and they also ask just as to what it means to also have Solar on the side as well.

When you look at most larger fifth-wheel campers, today they are coming in a configuration more geared toward boondocking camping off-grid. A lot of these trailers will have on-board generator and also the pre-wired solar ports.


Cable Entry Plate

The cable entry plate that is used on many fifth wheel roofs to prewired the unit for solar.

The pre-wired solar on the roof is designed to do one of the most troublesome parts of adding solar to your fifth wheel, and that is wiring the cable from the roof down into the RV to where the charge controller resides.

What manufacturers have done is to install the Go Power cable entry plate in many cases to bring a quick connect MC for type connection from the roof down to the back where a charge controller will be placed. This location is often marked with a sticker that looks like charge controllers. There will usually be two sets of wires, one for the array and another for the battery connection. Connecting the charge controller to both the array wires and the battery wires minimizes how much additional wiring needs to be done inside of the walls of the RV. Many fifth-wheel trailer owners will install between 380 and 1500 watts of solar panels for battery charging.

The port on the side is for additional solar once the roof is full. The solar on the side port is excellent for adding a portable panel when you need to get a little extra power in certain areas. I usually recommend that people feel the roof on a fifth wheel first with solar because it always works and it does not need to be put out. But if you need more power when camping under trees and are able to get a little further away from the camper a portable solar panel like to go power 200-watt portable is always a great choice.

Some times it is necessary to customize the different solar kits with additional wiring to match your specific camper’s requirements. Let us know if you will need a varied solar panel layout.

Finding lost prewired solar wires

It is very frustrating to find cables that are in an RV that was prewired at the factory, but the locating stickers were removed.

A few tips are look for pictures of your RV on the internet as they often have these stickers still installed in videos and diagrams. Another is to use a tool to search for the cables. These scopes can really help with lots of projects like this and aare a great tool to have around.
