>but the Northern Lights website is a joke--can't even get complete specs on their 8kw unit. I wouldn't judge the company by its website. Northern Lights generators have certainly been the world standard for many years. Their specialty is propulsion engines and generators, not the internet. I'd recomend you call the company directly for whatever information you need. C. Marin Faure GB36-403 "La Perouse" Bellingham, WA
