One thing I would like to bring to your attention. As a generator tech(military and civilian), I have worked with those rotating magnet generators, Generac and Onan. They have been known to throw their magnets due to glue failure and/or impacts from jostling where the magnets contact the windings/housings. I've replaced a couple rotors and still have some of the balls of broken magnets I brought home for my son. I'm not trying to put you off the generator, you got it at a great price
, just letting you know that is one possible failure point.
