I've been in the market for a 2000w inverter generator. I'm under the impression I need a pure sine generator and most of the lower cost inverter generators put out a Stepped approximation to a sinewave. Unless I'm mistaken, this won't work with my harman as when it picks up a stepped sine wave signal it'll go into shut down mode. So far the only model that puts out a pure sine wave i've seen is the Honda EU2000i. Are there any other generators to consider in this space?
