The three-phase on-grid PV inverters work with grid (380/400/415/440 Vac,
50/60 Hz).
The external AC switch should be installed between inverter and grid to isolate
from grid. Please make sure below requirements are followed before connecting
AC cable to the inverter.
·
The AC (grid) voltage must not exceed inverter’s range
·
The phase-line from AC distribution box are correctly connected
·
Use the AC plugs in the accessory
·
The surge protector should be equipped between grid and inverter
·
Disconnect the AC (grid) switch during wiring
