Description
Specifies the inverter protection threshold when the power grid voltage is
unbalanced.
The Japanese standard requires that during passive islanding detection,
protection should be triggered if an abrupt voltage phase change is
detected.
The standards of certain countries and regions require that the inverter
needs to be protected when the phase angle offset of the power grid three
phases exceeds a certain value.
Specifies the 10-minute overvoltage protection threshold.
Specifies the 10-minute overvoltage protection duration.
