Parameter Description
Level-N overvoltage protection
threshod (V)
Species the level-N grid overvoltage protection threshold.
NOTE
● N can be 1, 2, 3, 4, 5, or 6.
● When HVRT is set to Enable, and the value of Level-1 overvoltage
protection threshod is larger than that of HVRT threshold, the
solar inverter may repeatedly start and shut down if the power grid
voltage is between the two values.
Level-N overvoltage protection
duration (ms)
Species the level-N grid overvoltage protection duration.
NOTE
N can be 1, 2, 3, 4, 5, or 6.
Level-N undervoltage protection
threshod (V)
Species the level-N grid undervoltage protection threshold.
NOTE
● N can be 1, 2, 3, 4, 5, or 6.
● When LVRT is set to Enable, and the value of Level-1
undervoltage protection thresho is less than that of LVRT
threshold, the solar inverter may repeatedly start and shut down if
the power grid voltage is between the two values.
Level-N undervoltage protection
duration (ms)
Species the level-N grid undervoltage protection duration.
NOTE
N can be 1, 2, 3, 4, 5, or 6.
Level-N overfrequency
protection threshold (Hz)
Species the level-N grid overfrequency protection threshold.
NOTE
N can be 1, 2, 3, 4, 5, or 6.
Level-N overfrequency
protection duration (ms)
Species the level-N grid overfrequency protection duration.
NOTE
N can be 1, 2, 3, 4, 5, or 6.
Level-N underfrequency
protection threshold (Hz)
Species the level-N grid underfrequency protection threshold.
NOTE
N can be 1, 2, 3, 4, 5, or 6.
Level-N underfrequency
protection duration (ms)
Species the level-N grid underfrequency protection duration.
NOTE
N can be 1, 2, 3, 4, or 5.
