Parameter Description
Average active power ltering
time (ms)
Species the period of active power rise due to sunlight
changes. This parameter is used with Plant active power
gradient.
Power factor Species the power factor of the inverter.
This parameter is displayed if Remote power schedule is set
to Enable.
Reactive power compensation
(Q/S)
Species the reactive power output by the inverter.
Overfrequency derating If this parameter is set to Enable, the active power of the
inverter will be derated according to a certain slope when the
grid frequency exceeds the frequency that triggers
overfrequency derating.
Frequency for triggering
overfrequency derating (Hz)
The standards of certain countries and regions require that the
output active power of inverters be derated when the power
grid frequency exceeds a certain value.
● This parameter is displayed when Overfrequency derating
is set to Enable.
● When setting this parameter, ensure that the following
condition is met: Frequency for exiting overfrequency
derating ≤ Frequency for triggering overfrequency
derating <
Cuto frequency of overfrequency derating.
Frequency for exiting
overfrequency derating (Hz)
Species the frequency threshold for exiting overfrequency
derating.
● This parameter is displayed when Overfrequency derating
is set to Enable.
● When setting this parameter, ensure that the following
condition is met: Frequency for exiting overfrequency
derating ≤ Frequency for triggering overfrequency
derating <
Cuto frequency of overfrequency derating.
Cuto frequency of
overfrequency derating (Hz)
Species the frequency threshold for cutting o overfrequency
derating.
● This parameter is displayed when Overfrequency derating
is set to Enable.
● When setting this parameter, ensure that the following
condition is met: Frequency for exiting overfrequency
derating ≤ Frequency for triggering overfrequency
derating <
Cuto frequency of overfrequency derating.
Cuto power of overfrequency
derating (%)
Species the power threshold for cutting o overfrequency
derating.
● This parameter is displayed when Overfrequency derating
is set to Enable.
