Allen, would you have to use 3 Sunny Islands? one for each phase?
<br>
The Utility wants a single inverter.

I do not know what is going on at Outback, but unless they reduced the
product offering, they have the capability. I have such a system.
<br>
<br>
Use 3 of their 120 volt single phase inverters connected 3-phase WYE
(120/208) 3 phase. Each inverter is only a single phase, and you
connect each inverter to the neutral and one phase, you program one to
be the Master, and the others to be slaves on phase B and Phase C.
When you lose the grid, the Master inverter starts its sine wave and it
generates the usual 60 Hz square wave on the Outback Bus and the
following slave units delays the start of their sin waves by the
appropriate 120 degrees to generate 3 phases. Each inverter picks up
and makes 60 hz 3 phase.
<br>
<br>
One thing, besure to get a rotation meter and check that you are
generating 3-phase the same rotation as the grid. Else you will have
big problems. (motors will reverse and you may fry the OB transfer
relay)
<br>
<br>
Next time you call outback ask a tech if you can slave the GVFX to make
3 phase,
<br>

Jeff,
<br>
That was my first choice, but I was told by Outback
<br>
that they do not offer
<br>
a 120/208 inverter(s). I have not set up a three
<br>
phase system yet, so bare
<br>
with me please. I was going to contact SMA next.
<br>
<br>
