cosφ-P/Pn 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 cosφ-P/Pn characteristic curve control mode is to dynamically adjust the power factor
cosφ in accordance with the P/Pn (%) based on the VDE-4105 and BDEW German standards.

The Q-U hysteresis curve (CEI0-16) control mode is the Italian standard CEI0-16 version of
the Q-U characteristic curve. It dynamically adjusts the output reactive power of the solar
inverter in accordance with the ratio of the actual voltage to the rated voltage. The final value
should be in the form of Q/S.

Description
Set this parameter to cosφ-P/Pn characteristic curve.
Specifies the number of characteristic curve points.
The characteristic curve supports a maximum of 10 valid
points.
When configuring the curve, ensure that the P/Pn(%) value of
a point is greater than the P/Pn(%) value of the previous
point. Otherwise, the message indicating invalid input will be
displayed.
Description
Set this parameter to Q-U hysteresis curve(CEI0-16).
