Yep my Best Power UPS is the largest that they build that runs off 13.8 volts it's a 1.4 KVA. I have a question, How long does the 4 33AH batteries last at what ever load that you have connected, and is it a fairly light load? It seems that they wouldn't last long with much of a load. AC0Y

The one I just listed uses an internal DC voltage of 48 volts, with all 4 33AH batteries in series. I agree with you though, the more times you "convert" voltage from one level to another decreases efficiency. At one of our club sites, we have a bank of 6 "2 volt" 500AH cells in series, being charged by a commercial Staticon unit. The batteries only have to last about 2 minutes, as there is a HUGE generator that powers everything at the site.
