Description
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 the SUN2000 be derated
when the grid frequency exceeds a
certain value.
Specifies the frequency threshold for
exiting overfrequency derating.
Specifies the frequency threshold for
cutting off overfrequency derating.
Specifies the power threshold for
cutting off overfrequency derating.
Specifies the power recovery gradient
for overfrequency derating.
Specifies the time for filtering the grid
voltage in the PF-U curve.
Adjusts the apparent output baseline of
the inverter.
Adjusts the active output baseline of
the inverter.

-

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 ≤
Trigger frequency of over
frequency derating <
Cutoff frequency of
overfrequency derating.
