Description
Specifies the inverter
protection threshold in
the case of unbalanced
power grid voltage.
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 three-phase
angle offset of the power
grid exceeds a certain
value.
Specifies the 10-minute
overvoltage protection
threshold.
Specifies the 10-minute
overvoltage protection
duration.
Specifies the level-1
overvoltage protection
threshold.
Specifies the level-1
overvoltage protection
duration.
Specifies the level-2
overvoltage protection
threshold.
Specifies the level-2
overvoltage protection
duration.
