I installed 3 Fronius Symo 480V inverters specifically, because they list the grid type as 480V Delta + N. I connected them to a 480 delta system. Along with a neutral and ground coming from the service disconnect. A and B phase read 240 phase to neutral and C phase reads 415 ground to neutral. Fronius is telling me the inverter wont turn on, because it sees the high leg out of voltage range. I am confused, because when i think of a delta system it generally has a high leg. Anyone every installed a Fronius Symo before? I know they are relatively new. On the phone a tech told me the legs should all read 277 which is a Wye configuration. Their grid specialist was supposed to call me back Friday afternoon and didn't.

I saw nothing about no high leg delta systems.
