Solar Question
This is not a RV application but there seems to be a lot of solar knowledge on here so I thought I would ask. I run a 12V system in my remote cabin for LED lights and RV size water pump and CD play...

I re-read the original post, and came to the conclusion that the only way batteries can stay in that cabin is if they were AGM, fully charged and disconnected before the owner departed, or...
- Maintained by enough solar panels to render a 500 ma potential 24 hours a day meaning at least a 1.5 ampere charge potential per battery over a 5 hour period. Daily
- Not being familiar with the newer panels it's a matter of how many panels or what size panel can render a 1.5 amp potential per battery in that "Deep rainforest shade"
- Would it take 10 amperes full sunlight panel to so this? Twenty amperes worth of panel to render 1.5 amperes per battery?
- Folks here with panel experience are in a good position to offer an educated guess
- But several months spent with no charge is too long for a conventional battery
- Is a change to AGM more cost effective?
- They charge faster and self-discharge slowly especially in cool or cold weather
- Then too, they are small and not heavy and can be stowed for the trip back and forth
- There really isn't a crystal clear best solution for this IMO
