Description
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.
Specifies the level-N grid overvoltage protection threshold.
NOTE
● N can be 1, 2, 3, or 4.
● When HVRT is set to Enable and Level-1 overvoltage protection
threshold is higher than Threshold for triggering HVRT, if the grid
voltage is between Threshold for triggering HVRT and Level-1
overvoltage protection threshold, the SUN2000 could start and shut
down repeatedly.
Specifies the level-N grid overvoltage protection duration.
NOTE
N can be 1, 2, 3, or 4.
Specifies the level-N grid undervoltage protection threshold.
NOTE
● N can be 1, 2, 3, or 4.
● When LVRT is set to Enable and Level-1 undervoltage protection
threshold is lower than Threshold for triggering LVRT, if the grid
voltage is between Level-1 undervoltage protection threshold and
Threshold for triggering LVRT, the SUN2000 could start and shut
down repeatedly.
Specifies the level-N grid undervoltage protection duration.
NOTE
N can be 1, 2, 3, or 4.
Specifies the level-N grid overfrequency protection threshold.
NOTE
N can be 1 or 2.
Specifies the level-N grid overfrequency protection duration.
NOTE
N can be 1 or 2.
Specifies the level-N grid underfrequency protection threshold.
NOTE
N can be 1 or 2.
Specifies the level-N grid underfrequency protection duration.
NOTE
N can be 1 or 2.
