Kisae SW2420 PSW Inverter 24VDC-120VAC

I found there's less battery heating and better efficiency. Trying to run air on 12v was scary- lots of heating in all components. 24v was better, but 48 is a piece of cake. The less amps you can deal with the better.

I think as the conversion difference is smaller, the efficiency is better. Although I will add that the idle current for my 4k 48v inverter is much more (although still insignificant) than a 12v unit.

Well, we're not going to be running AC. Even when there's shore power we'd rather just use a 35W floor fan to keep cool. And if it gets worse than that, it's time to move further North. We're Snowbirds after all. The main reason for this whole RV thing is to track the seasons. If I wanted to stay down in Florida/Arizona all year, I'd buy a house.

And we'd have to get a bigger trailer if we decided to use much more electrical energy. 4 GC2s are close to the max on our tongue, and even this 2000W Kisae inverter is a pretty large. I'll probably have to move some stuff from the pass-thru to the truck's bed just to free up space for air-flow. Anything larger would be a bigger problem.

Currently we just turn off the 1000W inverter when we're not using it. But I'm curious how the Kisae's less than 100ma stand-by mode will work with our 120VAC usage. Apparently it wakes up every few seconds, and if there's greater than 10W load it stays on until the load drops to 3W, when it goes back to stand-by. The Microwave might not like this. We'll see. But even when this mode is turned off, the draw isn't bad, less than 600ma. Or we could just turn it off like we do now. We're not running a frig or anything essential like that on it. Not yet anyway.
