Enphase lists the standard operating range for the 208-volt 3-phase configuration as 183 to 229 volts. Seems like 220-volt 3-phase might work with a little caution about wiring losses.

Interesting....Here is a reply from Enphase received on 4-11-13, "Hi Larry, No we do not have a inverter that will work with this. Our inverter is for 240AC 2 Phase, 208AC 3 Phase..."

Hi Larry,

Enphase is supplying microinverters into Mexico and supporting the 127/220 applications. We have hundreds of installations installed at this voltage now. Feel free to contact me off-line, and I would be happy to discuss the details.

    Wrenches,

    A customer in Mexico wants to start with about 10kW PV. They have
    a 225 kva transformer supplying 220/127 volt 3-phase to the
    property. They are adding buildings/roof space in several stages
    over the next 4 years and want to grow the installation to 120kW
    of PV solar power.

    Manufacturer data sheets are not real clear. Who makes
    micro-inverters suitable for this? I know Enphase does not.

    Thank you,

"Don't get me wrong: I love nuclear energy! It's just that I prefer fusion to fission. And it just so happens that there's an enormous fusion reactor safely banked a few million miles from us. It delivers more than we could ever use in just about 8 minutes. And it's wireless! ."
