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.

Try the inverter without its chassis ground connected to the rig's frame.
One of my inverters has a weird ground set up inside it, so when you plug shore power into it, the 120v shore power plug's ground prong has another path to the rig's frame via the inverter's chassis ground to frame wire. The result is that when I try to do a battery disconnect using the ground side of the battery the rig's 12v is still working if the shore cord is plugged into the inverter.
Yours will not be quite like that, but could have some weirdness of that type causing the rig's GFCIs to pop.
