RV Solar Kits and Inverter Power Systems


Having solar panels charging your batteries in your RV is now mainstream and growing

When we first started selling and using panels to charge batteries on our RV’s back in the early 2000’s, our use was an oddity. This oddity has become mainstream. More and more users are attracted to the freedom found by having off grid power at their fingertips. This has been powered by the following market and social forces:

  • Mobile first workforce
  • Mobile internet
  • Lithium RV Battery banks
  • More efficent solar modules and panels
  • Inrcreased awareness in ability to go off-grid
  • More efficent LED lighting
  • Decreasing prices for the solar gear
  • Better pure sine inverter systems

Installing solar on a Four Winds Class C RV

Plug into Freedom: Simplifying the Installation of an RV Solar Kit

Four Winds Class C by Thor was the basis for this solar intall

We’ve completed the installation of two solar panels on a Class C Four Winds RV in about a day. The rv solar panel install was about 3 hours of the installation time. There were other components we added as well. With the solar upgrade, the RV will now have a reliable and sustainable source of energy that will allow running various electrical appliances and devices without relying on shore power or a generator.

Pre Wired RV solar in this Thor, made this installation super easy!

The pre-wiring of this particular Thor RV made the process a lot easier, but we still had to carefully choose the right size and type of solar panels and accessories that fit your needs and the specifications of the RV.

A cable entry plate was used for this RV prewired solar install

The cable entry plate was used, which made solar panel system wiring easier. We added a little extra caulk to help this cable entry plate deal with some pulled-away sealant. This cable entry plate was added at the factory for those not familiar with this RV solar program. This unit had a preinstalled controller made to support one panel. This made finding the prewired solar wires much easier.

Preparing the RV’s roof for sealing and mounting the panels

We prepared the surface and carefully worked on laying out the panels. This RV had an area where plywood was used under the roof to support more robust solar panel mounting. We followed the recommendations from the manufacturer of the RV. We also used extra brackets for a more rigid installation, as the owner was concerned about the wind on the road.

Adding the solar panel brackets to the panels

The mounting of the panels on the roof was a critical step, and we made sure they were securely fastened. We used traditional mounting brackets and sealed the installation using the owners’ sealant.

The back of the solar panel

We also had to upgrade the controller to ensure it could handle the increased capacity of the two panels. The original controller was only ten amps, but we replaced it with a 30 amp PWM controller from Go Power!

Upgrading 10 amp controller to 30 amp controller

Since it was a prewired solar installation, we connected the panels with a matching branch connector set and then used a set of 3-foot MC-4 extension cables to connect to the branch connectors to the cable entry plate.

TIP: The rv solar panel boxes are great for laying out the panels on the roof. They are also great for covering rv solar panels when working with their connections. This shading will reduce their power output. Be sure to cover all panels completely.

With the successful completion of this installation, the owner can now enjoy the benefits of renewable energy on their next adventure. The RV now has the independence and comfort of running many electronics wherever and whenever they want. All while reducing their camping’s carbon footprint. Congratulations on this upgrade!

RV Prices are falling!
Are RV Prices Falling?

Economic conditions are changing swiftly. Inflation is high, and interest rates are rising rapidly to combat inflation. One could only expect that market forces that drove RV prices higher, when reversed, should push prices down. In the last few years, let us consider all the unusual factors that caused RV prices of both new and used units to go up significantly.
