I have 1- 12volt Switch, 1-24 Volt Switch, 2- Inverter Switches and a By-pass Switch for Computer to Keep it energized I guess.
One of the things that bother me is the Fan that runs 24/7 in the inverter bay. I just replaced it because the original one stopped working. I am thinking about putting it on a t-stat. The other issue has to do with Compressors, I have a air compressor which cycles from time to time. It may be the awning compressor or the Aux. Compressor. I don't really know because they are hidden in the middle of the Coach. I am turning things off to try and identify whats going on.

So I am guessing by the responses, for the sake of the batteries, it is best to leave the 12 volt, 24 volt and the 2 -Inverters on. And turn off all loads at the Circuit Breaker Panel inside.
