No. Parameter Description Remarks
13 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.
-
14 Trigger frequency
of 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:
Quit frequency of
overfrequency derating ≤
Trigger frequency of
overfrequency derating <
Cuto frequency of
overfrequency derating.
15 Quit frequency of
overfrequency
derating (Hz)
Species the frequency threshold
for exiting overfrequency
derating.
16 Cuto frequency of
overfrequency
derating (Hz)
Species the frequency threshold
for cutting o overfrequency
derating.
17 Cuto power of
overfrequency
derating (%)
Species the power threshold for
cutting o overfrequency
derating.
18 Power recovery
gradient of
overfrequency
derating (%/min)
Species the recovery rate of the
overfrequency derating power.
19 PF-U voltage
detection ltering
time (s)
Species the time for ltering the
grid voltage in the PF-U curve.
-
20 Active power
baseline (kW)
Adjusts the active output baseline
of the inverter.
The apparent power baseline
must be greater than or equal
to the active power baseline.
21 Apparent power
baseline (kVA)
Adjust the apparent output
baseline of the inverter.
22 Communication
disconnection fail-
safe
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
specied by
Communication disconnection
detection time.
