I have a very cheap modified sine wave inverter that I hooked up with a DPDT switch and proper fuses to be able to provide power to my camper outlets when shore power is not available. One side of the switch swaps the outlets between the shore power breaker and the inverter (with a fuse downstream of the inverter output), and the other side of the switch turns on power to the inverter as needed so it's not running when I have shore power available. The problem is neutral floats 60v above ground, which I know is common in inverters and generators. Obviously it throws the GFCI outlet in my garage that I have running to my camper as it can't deal with the floating neutral. I'd like to get a nicer inverter but when I look at specs for them I never see it listed if it has a proper neutral at ground potential. Is that even such a thing or are they all designed this way? Should I be concerned about floating neutral or is it not a big deal? What about the ground pin built in to the outlet on my inverter; do I just not use it, now? Doesn't seem safe.
