Parameter
Description
Remarks
Power factor
Specifies the power factor of the
inverter.
This parameter is displayed
if Remote power schedule
is set to Enable.
Reactive power
compensation (Q/S)
Specifies the reactive power output by
the inverter.
Night-time reactive
power compensation
(Q/S)
During the reactive power
compensation at night, the reactive
power is scheduled by percentage.
-
Night-time reactive
power output
In some specific application scenarios, a
power grid company requires that the
inverter can perform reactive power
compensation at night to ensure that
the power factor of the local power grid
meets requirements.
This parameter is displayed
when Isolation settings is
set to Input ungrounded,
with TF.
Enable reactive power
parameters at night
When this parameter is set to Enable,
the inverter outputs reactive power
based on the setting of Reactive power
compensation at night. Otherwise, the
inverter executes the remote scheduling
command.
This parameter is displayed
when Night-time reactive
power output is set to
Enable.
Night-time reactive
power compensation
(kVar)
During the reactive power
compensation at night, the reactive
power is scheduled by fixed value.
This parameter is displayed
when Night-time reactive
power output and Enable
reactive power parameters
at night are set to Enable.
Overfrequency 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 frequency exceeds the
frequency that triggers overfrequency
derating.
-
Frequency for triggering
overfrequency derating
(Hz)
The standards of certain countries and
regions require that the output active
power of inverters be derated when the
power grid frequency exceeds a certain
value.
● This parameter is
displayed when
Overfrequency derating
is set to Enable.
● When setting this
parameter, ensure that
the following condition is
met: Frequency for
exiting overfrequency
derating ≤ Frequency
for triggering
overfrequency derating
< Cutoff frequency of
overfrequency derating.
Frequency for exiting
overfrequency derating
(Hz)
Specifies the frequency threshold for
exiting overfrequency derating.
Cutoff frequency of
overfrequency derating
(Hz)
Specifies the frequency threshold for
cutting off overfrequency derating.
