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.
