I was reading at a site last night that caters to the Recreation Vehicle crowd. Many there were telling people with questions about inverters that THEY use modified sine wave inverters for most everything except microwave ovens and some compact fluorescent lights.
I have two modified sine wave inverters. One is a Cobra 800 watt unit that accepts short surges up to 1200 watts. The other is a 2000 watt unit that accepts surges up to 2500 watts (I've forgotten the brand name).
I can run my refrigerator on the large one. But I've read that it may damage the motors on many compressors - or at least cause them to run hotter than usual.
I've never tried delicate electronics with either. But people at this site were claiming they could run TVs, battery chargers, computers, DVD players, and Hi Fi systems with the modified sine models. They were discouraging others from buying true sine wave inverters. Go figure!
I'd like to have a nice 1500 or 2000 watt generator in the under 40 pound variety. But I would want something that puts out a true sine wave. And the Honda and Yamaha models are very expensive - at least for my budget. My original question was about the generator/inverters. I was asking if the less expensive models were modified or true sine wave varieties?
Seems like it would be great if there was some sort of filter than would smooth out the signal. But that would probably cost a fortune too.
Thanks for the input,
