When deciding to Live in a RV, we realized and knew early on solar power was a must. The big issue with solar, is unless you go big, the ability to power big ticket items is limited. Things like an Air Conditioner just didn’t seem possible. Working with a small budget we did what we could and hoped for the best. This year, we finally got a chance to test out the Solar System, Battery Bank and Air Conditioner. What a shock!
This year, we finally got a chance to test out the Solar System, Battery Bank and Air Conditioner. What a shock!
We first tried a 10,000 BTU portable air conditioner. This was a flop. A single duct unit, everything you’ve heard about them is true. The exhaust duct created it seems more heat, then what the unit was able to offset with cooling. Not to mention the unit it self was large and took up considerable floor space. We couldn’t find a sufficient way to place it, while keeping it vented to the outside. Not to mention we paid around $320 for it. We’ve since returned it.
Enter a Walmart 6,000 BTU Air Conditioner.
For $156 we picked up a 6k BTU window mount AC. The wattage I could find online showed it to be under 600 watts, which is perfect for out 1.26 KW solar system. We choose the window in the bedroom for it, as the bedroom was the highest room in the camper, and the cool air would hopefully fall down into the rest of the camper. This worked, a little. We placed a couple fans to help direct the cooled air into the rest of the camper and success. The camper was cooling.
With a little bit of tinkering, we were able to get a 14′ difference between the 90′ air outside, and the AC cooled 76′ air inside. You’d think that wouldn’t be a big difference, but was it ever. Very impressive for a little 6k BTU Window Mount AC unit in a 31′ Fifth Wheel. Check out the video, proof is in there, and stay tuned. We’ve since replaced the 6k BTU unit, for a 10k BTU Window Unit ( around 900 watts ) and want to see what we can get out of that.
