7.5.2 Setting Protective Parameters
Protective parameters are designed for the threshold values that can trigger the
protective function of the inverter. The threshold values are compliant with the
requirements of local safety standards and the utility grid.
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.

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.
