Luke Hinkle, manager of Suntility Electric and founder of My Generation Energy said, “With the higher AC voltage, we could run longer branch circuits, use fewer combiner panels, and save on wiring costs. The design process was simpler, cleaner and less expensive. In addition, the system configuration avoids the need for secondary transformers, which reduces power losses and delivers more energy to the revenue-grade meter.”
Enphase's C250 Microinverter supports three-phase 480VAC installations for 60- and 72-cell PV modules.
