SSPort, I am not disagreeing with you about whether we have a battery or not, but the one time the power went out at the trailer last summer, we didn't have any lights on.
So, it is possible that the battery wasn't hooked up. I really don't know.
Let's say that either I do not have a battery or I need to upgrade my battery. I really would like something that would be able to go for a few hours and run everything.
I would buy a new one and attach it to something behind my propane tank? Would a 400V office backup battery be what I am looking for?
I agree with others, if you want to run everything you really should invest in a generator sized to handle the entire load of the rig. Whether it's financially feasible you'll have to decide how much it's worth to have power when the grid goes down.
