Too high grid voltage may affect the normal usage and the life of
household loads. The loss of any or all the warranty rights may follow if
the protection set-point is beyond the specified range.
Protection Recover
Vmax-rec (230.0 V–277.0 V):
Recovery value for over-voltage error. Inverter will start
operating when the grid voltage falls below this value.
Vmin-rec (179.0 V–230.0 V):
Recovery value for under-voltage error. Inverter will start
operating when the grid voltage is above this value.
