I threw this in an existing thread but didn't get much play on it so posting it fresh here.

Regarding my Trace Inverters and power consuption at night while dry camping:

Can I avoid draw on my batteries by shutting the inverter (the one not running the fridge) down at night OR does it help to turn the 12 or 24 volt mains (in the engine bay) off at night ? I never do either of these. I can always here the inverters internal fans running when I walk by the battery bay where they are located. These Internal fans have to be making a draw. Are they ever supposed to shut off ? If there is a thermostat, maybe it's bad ??? Should they run even in mild 60 degree weather at night ?

Also, with the Inverters in with the lead acid batteries, are there fumes that are harming the inverters ?

On the 12 and 24 volt switches, are these supposed to be shut off when plugged in ? Do they make a draw if they are not or is it just a security measure to turn them off ?
