RV Solar Kits and Inverter Power Systems
RV travel and camping life powered by Solar, Inverters, batteries and gear.
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

12 Volt DC Fridges run in your camper, RV or vehicle
With all the summer heat, we have been so happy to have our 12 volt DC Refrigerator. Amanda at least once a month says that all vehicles should include a 12 volt DC rerigerator that just runs on a built in solar panel. Our Fridge has run Problem Free in our Sprinter van since 2015. It has brought home groceries, provided camping food, transported fish, and been a constant supply of super cold drinbks.
Ebikes and Unicycles are all the rage off-grid and while camping

We went to the Crater of Diamonds to watch the 2024 Solar Eclipse. This being our 2nd chance to see it. It was amazing weather and we were lucky enough to see a solar flare near the bottom of the sun. What a cool experience, but we picked up a new viewpoint into how popular ebikes (electric bikes), one-wheels and electric unicycles, and golf cart have become. We have decided to add sections to these three items to our site to discuss what we have found. Our family now has a one wheel and are shopping for both 2 wheel and three wheel electric bikes. We have been on the gold cart band wagon for almost a decade, so we hope to share thoughts there.

Installing solar on a Four Winds Class C RV
Plug into Freedom: Simplifying the Installation of an RV Solar Kit
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.
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.
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.
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.
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!
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!
