Description
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.
During the reactive power
compensation at night, the
reactive power is scheduled by
fixed value.
Specifies the change speed of the
inverter reactive power.
Specifies the reactive power
adjustment time for an inverter.
Specifies the power factor of the
inverter.
Specifies the reactive power output
by the inverter.
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.
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.
Specifies the frequency threshold
for exiting overfrequency derating.
Specifies the frequency threshold
for cutting off overfrequency
derating.
Specifies the power threshold for
cutting off overfrequency derating.

● 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.
