Like many others, when we designed the solar install for our 2018 Flying Cloud 25 FB, we built it for 'low light' conditions to ensure that we had electricity when solar output was least optimal (winter sun, shade, clouds etc...). Our system, has significant redundancy as we are full timers and I work on the road. The system is split between Airstream (four 100 watt panels, 200AH lithium) and ford f150 tow vehicle (one 200 watt panel and 100ah lithium which is charged by both solar panel and truck alternator 30+ amps an hour if needed). If you are interested in whys and hows of our system here is a link to another post:

Anyway, our system is fairly robust and worked well for us during the winter months in all sorts of conditions. Our first summer on the road rolled around and suddenly we find ourselves fully charged by noon or earlier each day. What to do all the extra potential energy and not have the panels sit idle? Unfortunately, the power hungry fridge on 2018 flying clouds is a "two way fridge" which means it will run on propane or shore power (AC) but not d/c. I'm not sure whether that changed or not on newer models.
It turns out that the circuit for the fridge begins with the nightstand non-inverter electrical plug next to the bed and then goes to all the other non-inverter plugs and ends with the fridge. So, if you convert this circuit to run from inverter (and shore power) then automatically you will be able to power your fridge AND electrify all the rest of the plugs in the airstream to be able to run from the inverter as well. How nice! I don’t know how this works on other models but check out the wiring diagram in the back of the airstream manual to confirm. The rewire has worked flawlessly for months now.
The YouTube video link below explains how to do it. I'm also including a picture of my wiring diagram featured in the video (sorry for my poor penmanship).

Thanks and if you decide to do it and have questions, I will try to answer them as best as I could. PS I'm not an electrician, just handy. I ran the rewire plan past an electrician friend of mine and he thought it was ok, but this is definitely a DIY project.
