No. Parameter Description Remarks
16 Overfrequency
derating
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.
-
17 Frequency for
triggering
overfrequency
derating (Hz)
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 .
18 Frequency for
exiting
overfrequency
derating (Hz)
Specifies the frequency threshold
for exiting overfrequency derating.
19 Cutoff frequency of
overfrequency
derating (Hz)
Specifies the frequency threshold
for cutting off overfrequency
derating.
20 Cutoff power of
overfrequency
derating (%)
Specifies the power threshold for
cutting off overfrequency derating.
21 Power recovery
gradient of
overfrequency
derating (%/min)
Specifies the recovery rate of the
overfrequency derating power.
22 PF (U) voltage
detection filtering
time (s)
Specifies the time for filtering the
grid voltage in the PF-U curve.
-
23 Apparent power
baseline (kVA)
Adjust the apparent output
baseline of the inverter.
-
24 Active power
baseline (kW)
Adjusts the active output baseline
of the inverter.
-
25 Power percentage
for triggering Q-U
scheduling
Specifies the reference apparent
power, in percentage. When the
actual apparent power of the
inverter is greater than the value
of this parameter, the Q-U
characteristic curve scheduling
function is enabled.
