Parameter
Description
PF (U) voltage detection
filtering time (s)
Specifies the time for filtering the grid voltage in the PF-U curve.
Reactive power adjustment time
(s)
Specifies the adjustment time for the reactive power to reach the target
value during reactive power adjustment.
Power factor
Specifies the power factor of the inverter.
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.
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.
Night-time reactive power
compensation (kVar)
During the reactive power compensation at night, the reactive power is
scheduled by fixed value.
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.
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.
Cutoff power of overfrequency
derating (%)
Specifies the power threshold for cutting off overfrequency derating.
Frequency detection filtering
time (ms)
Specifies the frequency detection filter time.
Overfrequency derating power
drop gradient (%/s)
Specifies the decrease rate of the overfrequency derating power.
Power recovery gradient of
overfrequency derating (%/min)
Specifies the recovery rate of the overfrequency derating power.
Voltage 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 voltage exceeds the
voltage that triggers overfrequency derating.
Voltage derating start point (V)
Specifies the start point for voltage derating.
