    Check the neutral and earth ground at the Inverter and see if you get that on a dvm.

    Shows 0V on mine.

    Did you try to measure what it really is at AC1 terminals?

    I had a guy once that had a charger hooked up and some how it would back drive to a 2 way switch he had wired in a hallway and it would pass DC voltage back to the Inverter through the neutral and ground if it was plugged in. Gremlins !!

    So reading it with multimeter
    It matches the reading of the xw6048
    50v and DMM 49v

    With ac grid breaker on I got 3v between neutral and earth ..
    With ac grid breaker off I got 100v between neutral and earth..
    I don't have batteries negative conected to earth..
    At least intentionally only if xw do it by itself

    Apparently, your neutral is not connected to the ground, or it couldn't be 100V in there.

    But also, I guess the XW neutral is not connected to the grid neutral.
