Parameter
Description
1
Voltage unbalance protection
threshold (%)
Specifies the inverter protection threshold when the
power grid voltage is unbalanced.
2
Phase angle offset protection
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.
3
10-min overvoltage protection
threshold (V)
Specifies the 10-minute overvoltage protection
threshold.
4
10-min overvoltage protection
duration (ms)
Specifies the 10-minute overvoltage protection
duration.
5
Level-N overvoltage protection
threshold (V)
Specifies the level-N grid overvoltage protection
threshold.
6
Level-N overvoltage protection
duration (ms)
Specifies the level-N grid overvoltage protection
duration.
