Example
The parameters for points A to D are congured in this example as
follows:
Display Text Description
A cos phi: ind 1.00
Point A: cos φ is set to inductive
1.00. Since cos φ = 1.00, capacitive
could also be congured.
The power ratio P/Pn is automatically
set to 0% and cannot be changed.
B cos phi: ind 0.95
Point B: cos φ is set to inductive
1.00.
B P/Pn ratio: 23%
Point B: Power ratio P/Pn is set to
23 %.
C cos phi: cap 0.90
Point C: cos φ is set to capacitive
1.00.
C P/Pn ratio: 75%
Point C: Power ratio P/Pn is set to
75 %.
D cos phi: cap 0.95
Point D: cos φ is set to inductive
0.95.
The power ratio P/Pn is automatically
set to 100 % and cannot be changed.
This results in the following behavior from the solar inverter,
depending on the current fed active power:

When changing the currently fed active power, the cos φ runs along
the plotted line.

Function
If active power limitation is congured during commissioning and/or
through the "power reduction" function, the behavior of the "cos φ
(P)" function changes.

This active power reduction to 4 kW means point D can never be
achieved. This applies for the entire grey area.
