See my above post on gfi outlets. It didn't work, now I have 4 gfi outlets that trip. I called Magnum and they said you need to use a gfi outlet that's approved by us. They have many listed. I installed Leviton 8899 and no more tripping. I have gone from shore power to inverter and back again many times with no issues. It is an older model gfi outlet but ebay had many, just not dark brown, I installed white.
