As far as I know, you won't find a mobile listed inverter that can be grid tied (for the reason mentioned by Steve. I'm curious about how you are "feeding a GFI breaker." I think the best you can (legally and safely) do with a mobile system is to power loads using a listed mobile inverter plugged into and A/C transfer switch inlet at the premises, as if the portable solar energy system is a portable generator. The utility and the AHJ would not allow a "temporary grid-tied" PV system.
Any differing opinions?

If you install a Ground switching relay and isolate the input neutral from the output neutral bus's this will get rid of this problem... On a side note how did you get a utility (or have you) to approve a GT inverter on a mobile trailer? Steve Higgins. Sr Application Engineering Mgr Sub-Saharan Africa Business Dev Mgr.

Intermittently, we have a problem feeding GFI breakers. Its the strangest thing, sometimes it trips GFI's and other times it doesn't. Aside from the possibility that some of the GFI's aren't wired properly we haven't been able to figure it out. We have it plugged into a GFI at the shop (which is wired properly) and there is no problem. I thought there was a previous string on this issue but could not find it in the archives. What do you recommend for grounding portable units and what recommendations do you have from personal experience? Thanks! Wayne Irwin Director of Engineering Pure Energy Solar International Inc.
