No. Parameter Description Remarks
15 Quit frequency of
overfrequency
derating (Hz)
overfrequency derating ≤
Trigger frequency of
overfrequency derating <
Cuto frequency of
overfrequency derating.
Species the frequency threshold
for exiting overfrequency
derating.
16 Cuto frequency of
overfrequency
derating (Hz)
Species the frequency threshold
for cutting o overfrequency
derating.
17 Cuto power of
overfrequency
derating (%)
Species the power threshold for
cutting o overfrequency
derating.
18 Power recovery
gradient of
overfrequency
derating (%/min)
Species the recovery rate of the
overfrequency derating power.
19 PF-U voltage
detection ltering
time (s)
Species 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
specied by
Communication disconnection
detection time.
-
23 Communication
disconnection
detection time (s)
Species 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.
24 Active power mode
when
communication
fails
Species the protection threshold
of the active power after
communication is interrupted.
The value can be a percentage or
a xed value.
