So, I’ve had a number of people ask me about my solar setup on the RV. Frankly, it’s not all that extravagant, but it’s probably the single best modification I’ve done to my RV so far. Not just bang-for-the-buck, but all out best thing I think anyone can do for their RV.
I had purchased 6v batteries for the RV, but I didn’t want to waste the two 12v batteries that the coach came with. They’re only 80ah batteries each, but they were brand new when we got the RV…and I’m a waste-not, want-not kinda guy…so I’ve still got the 12v batteries in there, nearly a year later.
Brianna and I spend most of our time off-grid and not plugged into power. In the last 9 months that we’ve had solar, we’ve put approximately 50 hours on the generator. 10 or 11 of those hours were over a 2 day span mid summer when we wanted AC and had no access to shore power.
We do normal things while on battery. We have lights on at night, listen to music ALL the time on the surround sound system, or we’ll watch movies and such. We run the blender for smoothies. We have vent fans and a stand alone 12v fan. You know, normal stuff.
I installed energy efficient EVERYTHING into the RV. The lights are all LED. Even both smart TVs are LED. One is even 40″…So we’ve got that going for us. I check the voltage very regularly, as I’m pretty OCD about stuff being charged…we usually end a night sitting right around 12 to 12.2 volts. We usually wake up to 14 to 14.3 volts.
Solar. Solar was the best thing we’ve done to the coach so far.
I spent $339 on a kit from Renology on Amazon. It had two 100 watt solar panels, the mounting hardware, screws, all the connectors and 10AWG wiring necessary, and a 30amp PWM solar controller.
