Parameter
Description
Remarks
Cutoff power of
overfrequency derating
(%)
Specifies the power threshold for
cutting off overfrequency derating.
Frequency detection
filtering time (ms)
Specifies the frequency detection filter
time.
Overfrequency derating
power drop gradient
(%/s)
Specifies the decrease rate of the
overfrequency derating power.
Power recovery gradient
of overfrequency
derating (%/min)
Specifies the recovery rate of the
overfrequency derating power.
Voltage derating
If this parameter is set to Enable, the
active power of the inverter will be
derated according to a certain slope
when the grid voltage exceeds the
voltage that triggers overfrequency
derating.
-
Voltage derating start
point (V)
Specifies the start point for voltage
derating.
● This parameter is
displayed when Voltage
derating is set to
Enable.
● When setting this
parameter, ensure that
the following condition is
met: Voltage derating
start point < Voltage
derating stop point.
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.
N/A
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.
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.
