<div dir="ltr"><div>Wrenches,</div><div>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?</div><div>Michael</div><div>?</div><span class="gmail_signature_prefix">-- </span><br><div dir="ltr" class="gmail_signature" data-smartmail="gmail_signature"><div dir="ltr">
