Newbie power question
Shore power and everything works GenSet on and everything works Battery power alone and I'm limited to 12-volt system only? I have lots of battery capacity, shouldn't the inverter run the 110 out...

how do you figure you have 920 amp hrs of battery
lol..... I probably don't
I was estimating my x4 Ultra High-Cap Duracell house batteries.
Factory rated @ 230 Ah each. = 920 Ah. Perchance I miscalculated?
Those are (almost certainly) 6V golf cart batteries, connected in series-parallel to make 12V. The overall capacity of the system is 460 Ah at 12V. With a little rewiring you could indeed have a 920 Ah 6V battery bank, but of course that would not be very useful for powering 12V electrical devices. (You could also have a 230 Ah 24V battery bank, as well.)
This sort of confusion is very easy to get into partly because Ah are a measure of charge, not energy, and what we're really interested in is energy storage. I think it would be less confusing overall to think in terms of kWh, but pretty much nobody specifies RV battery banks that way.
