a Krieger 2000-watt inverter (I have the 1100-watt version in my camper, it's been running a 110v fridge 24/7 for about three months now, solar keeps the batteries charged all the time, they only drop to about 96% overnight).

And I'll probably get the same batteries I have in my camper too, four 6v Duracell EGC-2 from Sam's Club. They're actually made by Deka in the U.S.

And don't forget the battery monitor, I wouldn't ever build a battery system without one of these:

Oh, I also have a battery isolator switch so the truck alternator can also charge the batteries if need be.
