<p class="MsoNormal">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?<o:p></o:p></p>
