No. Parameter Description Remarks
25 Active power
threshold when
communication
fails (%)
Species the active power
threshold in percentage.
This parameter is displayed
whenCommunication
disconnection fail-safe is set
to Enable and Active power
mode when communication
fails is set to a percentage.
26 Reactive power
mode when
communication
fails
Species the protection threshold
of the reactive power after
communication is interrupted,
including Q/S and power factor.
This parameter is displayed
when Communication
disconnection fail-safe is set
to Enable.
27 Reactive power
threshold when
communication
fails
Species the Q/S threshold of the
reactive power.
This parameter is displayed
when Communication
disconnection fail-safe is set
to Enable and Reactive
power mode when
communication fails is set to
Power factor.
28 Closed-loop
controller
● If multiple inverters are
cascaded, the Smart Dongle or
SmartLogger is connected, and
closed-loop scheduling is
enabled, set this parameter to
SDongle/SmartLogger.
● If there is only one inverter
and closed-loop scheduling is
enabled, set this parameter to
Inverter.
● If closed-loop scheduling is
disabled, retain the default
value.

29 Underfrequency
rise power
The standards of certain countries
and regions require that when the
power grid frequency is lower
than the frequency threshold for
power raising, the device needs to
increase the active power output
to help increase the power grid
frequency. In this case, set this
parameter to Enable.
-
30 Power recovery
gradient of
underfrequency rise
power (%/min)
Species the power recovery rate
of underfrequency-caused raising.
This parameter is displayed
when Underfrequency rise
power is set to Enable.
31 Cuto frequency of
underfrequency rise
power (Hz)
Species the frequency threshold
for stopping underfrequency-
caused raising.
