At present there is no solar. I would like to get 400 watts on the roof if it were me. Its only a 25 foot RV so space is limited with the AC unit and skylight and fans, etc.
I really need to get a good wiring diagram of the RV ( 2015 Thor 24SA ) to see what isolator is installed for alternator charging. The stock unit may provide so little charging that taking that into account may not be of concern. I read somewhere that ideally 30a may be provided but I cannot verify that right now.
As always an energy audit is the best solution and I am winging it at the moment. This all started out after being told that on an overnight here in Maryland, that running the propane heater pretty much killed the batteries. Taking into account 6-8amp draw on on the 160ah total/80ah usable batteries, adding in running lights for a bit and other parasitic draws, the batts were more than likely taken to or below 50% of the 160ah.
I have a spare Renogy battery monitor that I was going to add inline to get a better idea of capacity and draw.
