Description
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.
This parameter is displayed if Remote power schedule is set
to Enable.
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.
Specifies the frequency threshold for exiting overfrequency
derating.
This parameter is displayed when Overfrequency derating is
set to Enable.
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.
Specifies the recovery rate of the overfrequency derating
power.
This parameter is displayed when Overfrequency derating is
set to Enable.
Specifies the time for filtering the grid voltage in the PF-U
curve.
Adjust the apparent output baseline of the inverter.
Adjusts the active output baseline of the inverter.
