Description
Specifies the change speed of the
inverter reactive power.
Specifies the rate of active power
rise due to sunlight changes.
Specifies the period of active
power rise due to sunlight
changes. This parameter is used
with Plant active power gradient.
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.

● 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.
