Wired for Solar


Wired for Solar Program promised easier conenctions for prewired RVs

Many trailers, fifth wheels, Class C and Class A and B motor homes come prewired for solar. You may have gotten a Wired For Solar sticker in your RV. That means that your RV has the wires built in ready to be connected to a solar kit or complete solar system. Outside Supply can help you get the parts you need to a Go Power Solar Kit to your vehicle.

Prewired kits speed solar panel installation on your RV

Pre-wired solar kits are meant to be installed on RV units that have been prepared to have a solar kit. This means that a solar wire pair should have been installed through the walls and roof using a cable entry plate or MC-4 wire directly. These kits are customized to add the parts you will need and eliminate the parts you do not.

Connecting to the wired for solar connector on the side of the RV

Connecting to the solar port on the side of your RV

The port on the side is connected directly to the battery in most wiring setups. Check your Rv's manual to make sure this is the case.
This port has a standard connector in many portable solar kits. Commonly referred to as an SAE connector. Portable kits usually have the charge controller in line or on the back of the panel. This is why the port usually is wired directly to the battery.
If there is a side connection, a customer needs to look at our portable solar units and our portable solar guide for more information.

Many of the portable solar kits come with a wide range of connectors. This allows easy connecting to your RV and also other equipment.

Install your panels on your RV if you can : BEST OPTION

Want to connect to the cable entry plate on the roof of your RV?

This cable entry plate is the best way to make permanent solar panel connections that are out of the way and mostly safe from theft. The CEP-25 has MC-4 connector attachments that allow for quick connecting solar wires to the panels. MC-4 cables will extend usually 18 inches from the panel. These should be fine to conenct to cable entry for a single panel install that is close to the cable entry plate. If you want more than one solar panel or you cable entry plate is far from panel install, ordering a couple of extra MC4 extension cables can make wiring easier on the roof. These cables are almost always ordered in pairs, so get two of them.

When adding panels this is where MC-4 branch connectors will come into play when wiring in a standard parallel configuration. Most of the expansion kits will come witht these although you can order them as matched pairs.

Panels and kits if you have a charge controller installed

A 30 amp controller can typically handle up top three of these 190 watt panels.

Finding solar panel prewired can be difficult for certain models of RV

Are you looking for where your prewired solar cables are in your RV?

A program designed to help the consumer with solar panel installs has caused them a lot of grief due to hard to find cable locations and wiring diagrams. Here are a few reasons why RVers have had issues with the prewired or Wired for solar program.

  • Sticker is removed at dealer prep
  • Sticker is place in wrong place in RV
  • Proper docmentation on controller and solar wiring not done well
  • The program would be better optimized if a small controller would actually be installed with all the wiring hooked. Small so it is cheap to aquire and is easily replaced with a new controller. Charge controllers are having a lot of changes coming to them as the industry heads to RV-C. This will mean the controller will be stored away and the panel to monitor it could be centralized or unified in your RV. Lets hope the RV-C makes the drop points easier to find and identify. Here are a few articles we have written to help you find the cables meant to run to the charge controller.

    MC4 Cables

    MC4 cables are specialized connectors for solar panel systems. Designed for outdoor use, they ensure a waterproof and secure connection between panels, inverters, and other components. Their standardized design simplifies installations, ensures compatibility, and reduces the risk of incorrect solar electrical connections. There is still a need to understand dangers of electrical work but having watertight quickconnects can be essential for safer and efficient rv solar setups.
