The inverter will still run since it is directly wired to the batteries, but the rest of the systems run through the relay. I assume the lights and other systems work when plugged in?

The point being other than AC & microwave you should fully self contained on battery, propane & water in your tank, if not somethings not right somewhere.

There's your problem. If it is in USE position then you have an issue between the batteries and the DC buss: Either the solenoid that the USE/STORE switch controls is not working or the DC breaker suppling that solenoid has tripped; look for a flag.
