Description
Specifies the power threshold for
cutting off overfrequency derating.
Specifies the recovery rate of the
overfrequency derating power.
Specifies the time for filtering the
grid voltage in the PF-U curve.
Adjust the apparent output
baseline of the inverter.
Adjusts the active output baseline
of the inverter.
Specifies the reference apparent
power, in percentage. When the
actual apparent power of the
inverter is greater than the value
of this parameter, the Q-U
characteristic curve scheduling
function is enabled.
The inverter adjusts Q/S (the ratio
of the output reactive power to
apparent power) in real time
based on U/Un(%) (the ratio of
the actual power grid voltage to
the rated power grid voltage).
The inverter adjusts Q/Pn (the
ratio of the output reactive power
to the rated active power) in real
time based on P/Pn(%) (the ratio
of the actual active power to the
rated active power).
The inverter adjusts the output
power factor cosφ in real time
based on P/Pn(%).
