What voltage is required to make SUNNY TRIPOWER CORE1 33kW work?
My local utility on my building is 220V-240V 3Ø Delta. Is the output voltage of Core1 480V aswell? Should i use a step-down transformer or a step-up transformer? In the manual the installation videos it shows that INPUT is from PV voltages. Then the OUTPUT is already 480V neutral. Meaning i need to stepdown this output to connect to the local Grid? Any help highly appreciated.
