I'm trying to hook up a 10kW solar system in a 120/208 3 phase set up. The system consists of 25 Enphase D380 Micro inverters and 50 230 watt solar modules. Enphase has provided me with a drawing, installation guide and engineer confirmation stating that the these inverters are in a Wye configuration. For some reason the LDC is insisting that the it is set up in a delta config. Does anybody have any ideas about to explain that this is wye? Or have an idea how to re draw the diagram to help them understand.
