Description
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: Quit frequency of over frequency 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.
In the inverter export limitation scenario, if this parameter is set to
Enable, the inverter will perform active power derating by
percentage when the communication between the inverter and the
SmartLogger or Smart Dongle is disconnected for more than the time
specified by Communication disconnection detection time.
Specifies the fail-safe detection time for the disconnection between
the inverter and the SmartLogger or Smart Dongle.
This parameter is displayed when Communication disconnection
fail-safe is set to Enable.
