PF-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 inverter, which then operates according to the configuration. The SmartLogger no longer adjusts the values.![]()
Set the parameters of characteristic curves under instructions from professionals to ensure that the inverters work properly.
The control mode of the PF-U characteristic curve is to dynamically adjust the PF value in accordance with the ratio U/Un(%) of the actual grid voltage to the rated grid voltage.

Description |
|---|---|
Set this parameter to PF-U characteristic curve. |
|
Specifies characteristic curve points. The characteristic curve supports a maximum of 10 valid points. |
|
When configuring the curve, ensure that the U/Un(%) value of a point is greater than that of the previous point. Otherwise, the "Invalid input" message will be displayed. |
