Here’s an overview of my flexible solar panels, battery bank, and solar charge controller components on my RV. Maybe this will give you ideas on how to install solar on your RV.

I now have three Unisolar flexible solar panels now that can’t been seen unless you’re on the roof. I’ve added a Morningstar MPPT charge controller, heavy gauge wire, and a Trimetric battery monitor and 2000 Watt Pure Sine Inverter to complete the setup.

SAMLEX 2000 WATT PURE SINE INVERTER WITH REMOTE
My two 6V golf cart batteries will supply the power to this inverter. I also have wired the output to a 30 Amp receptacle that I can simply plug my shore power cord into. This eliminates the need for additional wiring inside the RV. All I have to do is turn off (or disconnect) my charger while running off of the inverter. Finally, this inverter comes with a remote control and status panel that I have mounted inside the RV for easy powering on/off of the inverter.
MORNINGSTAR TRISTAR MPPT SOLAR CHARGE CONTROLLER
This is an upgrade to my PWM charge controller that I installed last year. The reason why I went with the MPPT charge controller is because my solar panels output around 44 – 48 volts. The PWM charge controller works great, but will only accept up to 15 volts. Therefore the remaining voltage (up to 48 volts) was not being used. I went with the PWM controller initially as a cheaper option (approx. $150) until I could afford the $400+ MPPT controller. I found a great deal on the MPPT controller on Ebay and made the bid.
The MPPT controller now takes full advantage of the 40+ volts from my panels converting the extra voltage into additional amps. For example, an 8 amp/44 volt input to the controller may produce 20 – 22 amps at 12 volts to my batteries. This is more than double the output of the PWM controller.
