Description
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.
Specifies the fail-safe detection time for the disconnection
between the inverter and the SmartLogger or Smart Dongle.
Specifies the derating value of the inverter active power by
percentage.
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.
Specifies the frequency threshold of Underfrequency rise
power.
This parameter is displayed when Underfrequency rise
power is set to Enable.
Specifies the recovery rate of Underfrequency rise power.
This parameter is displayed when Underfrequency rise
power is set to Enable.
Specifies the cutoff frequency of Underfrequency rise
power.
This parameter is displayed when Underfrequency rise
power is set to Enable.
Specifies the cutoff power of Underfrequency rise power.
This parameter is displayed when Underfrequency rise
power is set to Enable.
Specifies the exit frequency of Underfrequency rise power.
This parameter is displayed when Underfrequency rise
power is set to Enable.
Specifies the reactive power compensation mode of the
inverter output.
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.
