Parameter Description
1 Voltage unbalance protection
threshold (%)
Species the inverter protection threshold when the
power grid voltage is unbalanced.
2 Phase angle oset protection The standards of certain countries and regions require
that the inverter needs to be protected when the
phase angle oset of the power grid three phases
exceeds a certain value.
3 10-min overvoltage protection
threshold (V)
Species the 10-minute overvoltage protection
threshold.
4 10-min overvoltage protection
duration (ms)
Species the 10-minute overvoltage protection
duration.
5 Level-N overvoltage protection
threshold (V)
Species the level-N grid overvoltage protection
threshold.
6 Level-N overvoltage protection
duration (ms)
Species the level-N grid overvoltage protection
duration.
