As far as I can determine, the Enphase microinverters output 240VAC, so wired into the normal domestic DB/panel just like the 240V delivered by the USA grid. The IQ8H does 208VAC, for those buildings (typically apartments) in the US that are connected to Y-style transformers. The Enphase IQ8 microinverter, when used with their control box, can provide power from the pv panels to the house even when the grid is down. In the US they call this "solar backup" mode. So not necessarily grid-tied.

I'm also intrigued by micro inverters. Have had twelve years on an MLT Drives PowerStar 12kW, and six months on a Victron Quattro. I've sold the house and will be looking at a new installation in the next 6-9 months, so looking at options. My main unanswered question, though, is how to sync with the grid. I've been exporting surplus pv power to the grid, and would still want to do that. Not sure how that would be accomplished with micro inverters.

You're probably not aware that in the USA the grid delivers 240V to almost every house.
