Description
Specifies the period of active power rise due to sunlight
changes. This parameter is used with Plant active power
gradient.
Specifies the power factor of the inverter.
This parameter is displayed if Remote power schedule is set
to Enable.
Specifies the reactive power output by the inverter.
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.
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 < Cutoff frequency of overfrequency derating.
Specifies 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 < Cutoff frequency of overfrequency derating.
Specifies the frequency threshold for cutting off 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 < Cutoff frequency of overfrequency derating.
Specifies the power threshold for cutting off overfrequency
derating.
● This parameter is displayed when Overfrequency derating
is set to Enable.
