21�2�4 Variable Cos (Phi) Shift Factor Over Characteristic Curve P - Solar-Log 2000 Installation Manual

Special functions
If a certain reactive power in
Var have to be entered in the first line along with checking the Inductive box. The time 00:00 also has
to be entered in the other lines. It is not necessary to enter the reactive power.
21�2�4 Variable cos (Phi) shift factor over characteristic curve P/Pn
The function allows the Cos (Phi) to be adjusted according to characteristic curve P/Pn.
With a characteristic curve P/Pn, the ratio of the currently generated power (P) to nominal power
(maximum output) (Pn) is determined. A Cos (Phi) is assigned to ratio by a characteristic curve.
The currently generated power (P) is calculated by the Solar-Log™ based on the inverter data. Mea-
suring the power output intended.
The function is also referred to as Phi (P) .
Type of characteristic curve section
Using this menu item a characteristic curve specified by the grid operator can be stored. In principle a
distinction is made here between a 2 point and a 4 point characteristic curve.
2 point characteristic curve
By selecting "2 point characteristic curve" it is possible to define a characteristic curve using 2 points.
