Can you provide a wiring diagram of your installation? It appears to be a problem isolated to the sub panel or ATS.
Edit, on second thought, the problem is probably at the ATS, or between the ATS and inverter. I would verify wiring at the ATS paying special attention to proper/correct connection from the inverter. I suspect a wire assembly defect between ATS and inverter.
Agreed, my thoughts too were that the problem must be at the ATS. However, after more testing tonight now I am really stumped.
- Ran an extension cord from the inverter directly to the microwave and plugged the microwave into the extension cord. Everything worked perfect, no GFI trips.
- Ran an extension cord from the microwave to a different outlet in the trailer powered from inverter. It worked perfect again, no GFI trips.
- Now, here is the real mystery. Ran an extension cord from the SAME outlet the microwave was plugged into and then plugged the microwave into the extension cord. Effectively, all I have done is make the microwave power cord longer. CANNOT trip the GFI. I must have tried this 30-40 times because I couldn't believe it. However, plug the microwave into the same outlet without the extension cord and it will trip 1 out of 5.
Any thoughts? I am thinking I may try wiring in a different outlet or just extending the cable to the outlet and see if that fixes it, but I really don't understand what is going on.
