Magnum Hybrid Inverter and ground fault
Hi all, I've run into a problem with the Magnum 3000 hybrid. It appears to be tripping 15 amp ground fault outlets.

You probably ought to bond the inverter case directly to the chassis ground; I suspect that's required by the NEC. I believe it is for converters, at least, and the charger part of the inverter is essentially the same thing. I doubt very much this will prevent the GFI from tripping.
It sounds like the inverter is either causing a leak to ground or bonding neutral and ground somehow. If the charger output isn't isolated from the input power properly, I could imagine it might be a sort of ground fault. Likewise, if the inverter part is bridging neutral and ground, that could very well be an actual ground fault.
(All of that is not terribly helpful, I realize; it's pretty much just reiterating your initial statement that the inverter seems to cause a ground fault.)
Do you get the trip if the output of the inverter is left disconnected—i.e. if you don't plug the shore power cord into it?
