Inverter bonding would only occur when there is no AC input and the inverter is converting DC to AC vs shore passthough. Try the 3 light household tester on the inverter output as they should show a problem with a floating neutral.
Will do, but upon further examination, I’m finding some neutrals in the main tied to the ground bar, while some other neutrals are not tied to the neutral bar…Looks like in someway the ATS relay coil was able to sense this defect, yet WOULD operate (via the inverter) IF I ran the jumper from the ATS’s gen neutral terminal to chassis ground…
So it looks like the ATS’s relay was just an indicator of past bad things gone wrong at the main panel…Funny that all these years and no sign of a problem (or GFI trips) until the ATS install…
Main panel is a congested birds nest (both up front and behind - ugg)…
It won’t be fun :(
