Parameter
Description
Power recovery gradient of
overfrequency derating (%/min)
Specifies the recovery rate of the overfrequency derating
power.
● This parameter is displayed when Overfrequency derating
is set to Enable.
PF (U) voltage detection
filtering time (s)
Specifies the time for filtering the grid voltage in the PF-U
curve.
Apparent power baseline (kVA)
Adjusts the apparent output baseline of the inverter.
Active power baseline (kW)
Adjusts the active output baseline of the inverter.
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.
This parameter is displayed when Communication
disconnection fail-safe is set to Enable.
Closed-loop controller
Specifies the grid-tied power controller. Before setting the
parameter, confirm the controller type. Incorrect setting will
result in abnormal power output of the solar inverter. Solar
inverter applies only to the scenario where a single solar
inverter is used or where a single inverter is used with a Smart
Dongle.
Limit value for minimum PF of
Q-U characteristic curve
Limits the current PF value to restrict the Q-U curve output
reactive power.
Power percentage for triggering
Q-U scheduling
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.
Q-U characteristic curve
The inverter adjusts Q/S (the ratio of the output reactive
power to apparent power) in real time based on U/Un(%) (the
ratio of the actual power grid voltage to the rated power grid
voltage).
Q-P characteristic curve
The inverter adjusts Q/Pn (the ratio of the output reactive
power to the rated active power) in real time based on P/
Pn(%) (the ratio of the actual active power to the rated active
power).
Cosφ-P/Pn characteristic curve
The inverter adjusts the output power factor cosφ in real time
based on P/Pn(%).
