Mine came with 2 group 24 “hybrid” batteries. At best with a 22amp draw from the fridge those batteries are dead in 8 hours. Fried one of mine immediately. The inverter will shut itself down and will actually have a very loud audible alarm when close to shutdown (if you’re close by). You will have to turn the inverter on. Once on it should stay on unless of the low voltage situation and it shuts itself off or someone actually shuts it off. I keep my fiver inside a building plugged in at all times when we’re home. I found all this out due to a prolonged power outage in our area due to a storm about 4 years ago. The inverter should shut down before the batteries are completely dead however they will be way below the 50% state of charge required to not RUIN the lead acid batteries.

It is a box that connects to the battery via heavy gauge cables.

The red battery cutoff switch and inline auto-reset fuses aren’t it.
If you look closely at the pic in post #15 just above the cable wrap stuff is the inverter. when it is on I can see the green, yellow or red light and thats about about it. I have to reach up there and feel around for the on/off switch (which I will be leaving in the on position)

I think they all do that. If I am not mistaken I think the truck will keep the battery(s) charged enough so that it's not a problem.
