<p class="MsoNormal"><span style="color:#1f497d">We’ve recently run into an issue with a local distributor citing network fault current on a split-phase service as a reason to prevent interconnection of our customer’s solar array. They’ve given us the options
of reducing our system size from 36.5kW-DC to 15kW-DC, or having the customer upgrade to 3-phase at a soft price of $20-30K. We’re looking at 32kW of inverters on a 167kVA transformer.</span><u></u><u></u></p>
