Issue 15 (2023-01-31)
Description
Specifies 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 threshold 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.
Specifies the level-N grid overvoltage protection duration.
NOTE
N can be 1, 2, 3, 4, 5, or 6.
Specifies 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 threshold 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.
Specifies the level-N grid undervoltage protection duration.
NOTE
N can be 1, 2, 3, 4, 5, or 6.
Specifies the level-N grid overfrequency protection threshold.
NOTE
N can be 1, 2, 3, 4, 5, or 6.
Specifies the level-N grid overfrequency protection duration.
NOTE
N can be 1, 2, 3, 4, 5, or 6.
Specifies the level-N grid underfrequency protection threshold.
NOTE
N can be 1, 2, 3, 4, 5, or 6.
Specifies the level-N grid underfrequency protection duration.
NOTE
N can be 1, 2, 3, 4, or 5.
Specifies whether to enable the active islanding protection
function.
