These are 3 phase. I need single phase only.

If that were th only issue, I'm sure I could find a way around it, such as supplying some fake grid like power from a smaller inverter.

Smell like 3 phase to me.

Well, at least there is a single phase one in there. Rather pricy. Maybe it's all the grid-tie certification that adds to that ... plus the tranny.

More 3 phase.

Scoured their web site last night. Anything over about 3600 watts is grid-intertie at 3 phase.

Tons of 3 phase.

Much of this endeavor is aimed at being disconnected from the grid/utility. I'm sure solar will be a big part of the system. Wind might be, too. And I'll look for other possibilities such as waterfalls, wood burners, etc. But feeding power back to the utility is just not where I'm going with this at all.
