You could use a real inverter which has a higher capacity charger built in (much faster recovery time). Another advantage of an inverter is the batteries are sold separately so you can size them accordingly. You could have much longer run time on the batteries. Though having lead acid batteries on site might be an issue and large gelled cell batteries are expensive. Maybe it wouldn't be cost effective to use such a system for the rare power outage.
This little unit delivers 1000 watts continuous (3000 watts surge) and has a 50 amp battery charger. http://www.xantrex.com/web/id/55/p/1/pt/9/product.asp Greg On Jan 21, 2009, at 10:29 AM, Josh Luthman wrote: > Batteries won't last more then a few hours.
