My customer is installing a 250 kW ground mounted solar installation in New Jersey with a service connection that requires a three phase 240 V with a high leg delta. I am going to use a Xantrex GT250 three phase inverter with a 480 V output. What type of transformer is required to step down the voltage to enable this service? What exactly is a high leg 240 V 3 phase electrical service connection?
What type of transformer is required to step down the 240V delta service connection?
