Parameter
Description
Cut-off point of voltage derating
(V)
Specifies the stop point for voltage derating.
Voltage derating cut-off power
(V)
Specifies the power threshold for cutting off voltage derating.
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 specified by Communication
disconnection detection time.
Communication disconnection
detection time (s)
Specifies the fail-safe detection time for the disconnection between the
inverter and the SmartLogger or Smart Dongle.
Active power output limit for
fail-safe (%)
Specifies the derating value of the inverter active power by percentage.
Apparent power baseline (kVA)
Adjusts the apparent output baseline of the inverter.
Active power baseline (kW)
Adjusts the active output baseline of the inverter.
Frequency modulation control
The standards of certain countries and regions require that if the power grid
frequency fluctuates around a certain value, the inverter needs to fine-tune
the active power output based on Frequency modulation control droop to
help stabilize the power grid frequency. In this case, set this parameter to
Enable
Adjustment ratio of frequency
modulation control
Specifies the droop of the active power output.
Underfrequency rise power
The standards of certain countries and regions require that if the power grid
frequency is lower than Frequency for triggering of underfrequency rise
power, the inverter needs to increase the active power output to help
increase the power grid frequency. In this case, set this parameter to
Enable.
Frequency for triggering of
underfrequency rise power (Hz)
Specifies the frequency threshold of Underfrequency rise power.
Power recovery gradient of
underfrequency rise (%/min)
Specifies the recovery rate of Underfrequency rise power.
Cutoff frequency of
underfrequency rise power (Hz)
Specifies the cutoff frequency of Underfrequency rise power.
Cutoff power of underfrequency
rise power (%)
Specifies the cutoff power of Underfrequency rise power.
Frequency for exiting of
underfrequency rise power (Hz)
Specifies the exit frequency of Underfrequency rise power.
