Parameter
Description
Power factor
factor in certain periods of a day, add setting records based on
site requirements.
When multiple time points are set, the solar inverter will run
with the maximum power specified for the time point that is
earlier than and the closest to the current system time. For
example, if you add 00:00:00 and 12:00:00 on the WebUI and
the current system current is 14:30:00, the solar inverter will
run with the maximum power specified for 12:00:00.
Q-U Characteristic Curve
If you do not need the SmartLogger to send remote reactive power control commands, you
can configure the characteristic curve as a substitute. The SmartLogger delivers the values
configured for the characteristic curve to the solar inverter, which then operates according to
the configuration. The SmartLogger no longer adjusts the values.
Configure the characteristic curve under instructions from professionals to ensure that the
solar inverter works properly.
The Q-U characteristic curve control mode is to dynamically adjust the ratio Q/S of output
reactive power to apparent power in accordance with the ratio U/Un(%) of the actual grid
voltage to the rated grid voltage.
Parameter
Description
Reactive power control
mode
Set this parameter to Q-U characteristic curve.
Reactive power
adjustment time
Specifies the change interval of the reactive power for a
grid-tied point.
Trigger power ratio
Under a specific grid code, after you set this parameter, the
characteristic curve takes effect only when the actual output
active power of the solar inverter is greater than the preset
value.
Characteristic curve points
Specifies the number of characteristic curve points.
The characteristic curve supports a maximum of 10 valid
points.
U/Un(%)
When configuring the curve, ensure that the U/Un(%) value
of a point is greater than the U/Un(%) value of the previous
point. Otherwise, the message indicating invalid input will be
displayed.
