I do understand the frustration... I see multiple distinct issues reviewing this thread...
- Possible incompatibility of some GFI outlets with MSW inverters...
- Improperly wired (shared) neutrals between GFI/non GFI circuits...

For some, replacing GFI or inverter seemed to work... but would do nothing in the case of shared neutral downstream...

Something possible to try... how many outlets require GFI protection?
(Typically those within 6’ of sink or outside... guessing one in (each) bathroom... one in kitchen... one or two outside)
Thor uses one GFI to provide protection... but if you can determine to flow of outlets, on the existing GFI, move the downstream wiring to the ‘non protected’ side... ie GFI only protecting the ONE outlet... Install a new GFI in the second outlet in line, and see if problem goes away.. eliminates the wiring between 1 and 2 as issue.... Can continue down the line adding or moving... You could have individual GFI’s each protecting only one outlet - which would remove any coach neutral wiring issues.
(Or just as test swap regular and GFI outlet moving the GFI downstream until you find where it doesn’t trip...)
