Open delta three phase from only two primary lines

[jaggedben]

Yeah, we originally designed it with single phase inverters already knowing that it was an open delta supply before we even submitted our interconnection app. They are still fighting us on it

So wait...Did they reject single phase? If so, what was their reasoning? If not, what does the third phase have to do with anything?

If its a large system just add a single phase service for the PV up to class 320Amp you should be good.
