[RE-wrenches] 120/240 Delta

[Michael Morningstar]

Wrenches,
I have a customer that has asked me to provide their restaurant with PV and
battery back up. Easy-peasy or so I thought. It turns out that the service
that supplies the restaurant is being fed by two phases from a 120/240V
transformer. The service entrance conductors are direct burial and run
under a large paved parking lot, so there's no changing that arrangement.
I'm at a loss as what I can do here. I don't believe that something like a
Sol-Ark 18k is going to play nice with two legs 120 degrees out of phase?
The 30K definitely needs all three phases so a 240 Delta/208 WYE isn't
going to help? I don't even think there are micro-inverters or string
inverters available to give them just straight grid-tied and no BB. Are
there any solutions that I'm unaware of?
Michael
