Description
Adjusts the change speed
of the inverter active
power.
Adjusts the active power
output of the inverter in
fixed values.
Adjusts the active power
output of the inverter in
percentages.
Adjusts the change speed
of the inverter reactive
power.
Adjusts the power factor
of the inverter.
If this parameter is
enabled, the active power
of the inverter will be
derated according to a
certain slope when the
grid frequency exceeds
the value that triggers
overfrequency derating.
The standards of certain
countries and regions
require that the output
active power of the
inverter should be derated
when the power grid
frequency exceeds a
certain value.

Remarks
N/A
Pmax represents the
maximum active
power.
In the 1000 V
inverter, the upper
threshold for the
SUN2000-25KTL-U
S is 27.5 kW, and the
upper threshold for
other models of
inverters is Pmax.
If this parameter is
set to 100, the
inverter delivers the
maximum output
power.
