I ran my computers for years on modified square wave inverters, with no problems. I've heard dire warnings about laser printers though, for that I had a supplemental online true SW UPS. I did have problems with cheap electronics like timers (for turning your Xmas lights on and off), also lights with a motion detector, and mouse insanisizers (the gadgets that are supposed to make a high frequency noise to drive way rodents). Junk like that would usually only last a few days on modified square wave. The worst (e.g. $$$) trouble was that my SW UPS blew out after about 2 years of use, and then the replacement after about two weeks. I think that was a grounding problem though, and not necessarily related to the inverters.
--Douglas Is a pure sine wave inverter essential or would a modified square wave do just as well. [Non-text portions of this message have been removed] ------------------------ Yahoo!
