Description
During the reactive power
compensation at night, the reactive
power is scheduled by fixed value.
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
cutting off overfrequency derating.
Specifies the power threshold for
cutting off overfrequency derating.
Specifies the frequency threshold for
exiting overfrequency derating.
Specifies the recovery rate of the
overfrequency derating power.
Specifies the time for filtering the grid
voltage in the PF-U curve.
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.

Remarks
This parameter is displayed
when Night-time reactive
power output and Enable
reactive power parameters at
night are set to Enable.
N/A
● 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.
