I've got an apartment size refrigerator in my truck. Keep it full and it doesn't use as much juice. I'm running a 200w inverter and it powers a microwave, the refrigerator, a Mr Coffee and a laser printer. The refrigerator and a fan stay on all night and the truck never fails to start. Mr Coffee works just fine without starting the engine. Microwave and printer require constant voltage, so I high idle while using them.
Will an inverter run your battery down overnight?

Put a solar panel on top.
BlueThunderr, Dave_in_AZ, jammer910Z and 1 other person Thank this. -
I'd leave the battery switch on in the winter. It's cold enough the fridge never ran while at home.
In the summer I'd turn it off. The summer heat will have the fridge draining the batteries while at home.
I never had the other goodies and what electronics I had ran off a 400 watt invertor plugged in to the socket. Tv, laptop, printer.Tug Toy Thanks this. -
IF your low voltage alarm goes off when your in bed taking your 10 unplug the fridge and start the truck. Then as soon as you can get your batteries tested because 1 or 2 of them are bad. If your batteries are good there is zero reason for the fridge to run the down overnight..
You will also want 925+amp batteries..DieselDrivinDaddy Thanks this. -
Edit; been thinking about grabbing a small 2000w inverter generator for my side box just incase. It would keep the batteries up all night if I loose an alternator again.rabbiporkchop and mp4694330 Thank this. -
Dumb question but - how will the low voltage alarm go off if the truck is off? Referring to night time with truck off and fridge on. The alarm won’t go off unless key is on will it? -
Bean Jr. Thanks this.

I have a 2500 watt pure sine wave inverter. I always run the truck for high current loads, microwave, coffee maker, toaster, stove top plate.
A fridge draws the most current only while firing up, once running they don't draw very much. Plus they don't run constantly.
I accidentally forgot to shut off my fridge one weekend, but left the door open slightly. I discovered it on Sunday, but the truck still started. Outside temps were around 60 degrees.rabbiporkchop Thanks this. -
Except one.
She started eating alternators. Where in the world is a alternator with enough bawls to feed all that.FlaSwampRat Thanks this.
