Parameter
Description
Grid reconnection frequency
lower limit (Hz)
The standards of certain countries and regions require that after the inverter
shuts down for protection due to a fault, if the power grid frequency is
lower than Grid reconnection frequency lower limit, the inverter is not
allowed to reconnect to the grid.
Reactive power compensation
(cosφ-P) trigger voltage (%)
Specifies the voltage threshold for triggering reactive power compensation
based on the cosφ-P curve.
Reactive power compensation
(cosφ-P) exit voltage (%)
Specifies the voltage threshold for exiting reactive power compensation
based on the cosφ-P curve.
Protection Parameters
Parameter
Description
Insulation resistance protection
threshold (MΩ)
To ensure device safety, the inverter detects the insulation resistance of the
input side with respect to ground when it starts a self-check. If the detected
value is less than the preset value, the inverter does not connect to the grid.
Voltage unbalance protection
threshold (%)
Specifies the inverter protection threshold when the power grid voltage is
unbalanced.
Phase protection point (º)
The Japanese standard requires that during passive islanding detection,
protection should be triggered if an abrupt voltage phase change is detected.
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.
10-min overvoltage protection
threshold (V)
Specifies the 10-minute overvoltage protection threshold.
10-min overvoltage protection
duration (ms)
Specifies the 10-minute overvoltage protection duration.
Level-N OV protection (Hz)
Specifies the level-N grid overvoltage protection threshold.
Level-N OV protection time
(ms)
Specifies the level-N grid overvoltage protection duration.
Level-N UV protection (Hz)
Specifies the level-N grid undervoltage protection threshold.
Level-N UV protection time
(ms)
Specifies the level-N grid undervoltage protection duration.
Level-N OF protection (Hz)
Specifies the level-N grid overfrequency protection threshold.
Level-N OF protection time (ms)
Specifies the level-N grid overfrequency protection duration.
Level-N UF protection (Hz)
Specifies the level-N grid underfrequency protection threshold.
Level-N UF protection time (ms)
Specifies the level-N grid underfrequency protection duration.
