If the protection function is triggered, the inverter will automatically disconnect
from the grid with the ”Error xxx” state displayed on the LCD main screen. After
the grid voltage or frequency recovers to the specified range, the inverter will
start running normally and can reconnect to the grid.

* Refer to Tab. 7-7 for the default values of the parameters.
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.
