No, the constant RPM types produce a more or less "dirty" sine wave, depending on how "cheap" they are. The cheaper ones will have problems running some types of equipment.LTLFTcomposite wrote:Hopefully someone like ingineer would weigh in on this, but I think there are two types of generators, ones that run at a constant RPM (3600? or 1800 for diesels?) to produce the 60hz frequency, and others that use the magic of inverters to allow the engine to run at variable speeds. I have a honda 5000w like construction workers use that falls into the former category, while the EU2000 and 3000 most of you are talking about is the inverter type. Don't the constant RPM generators put out a regular sine wave as they are like miniature power plants, while the inverter types only approximate a sine wave?
The inverter ones, like my Honda EU65is, produce a very clean, near perfect sine wave. At least the expensive Honda ones does, what the cheap Kipor puts out I do not know. Supposedly the Honda puts out cleaner and better sinewaves than you get from the utility.
