cos φ(P)
In the cos ϕ (P ) operating mode, the setpoint value of cos ϕ and the setpoint for the reactive power derived from it are
continuously calculated depending on the actual power level. This function ensures that grid support is provided by the
reactive power when a significant voltage boost is anticipated due to a high feed level. In this case, a characteristic curve
is specified which can be used to configure up to 10 nodes, value pairs for active power and cos ϕ. The active power is
entered as a % in relation to the set maximum apparent power Slim. Other parameters allow you to limit functionality
and to limit activation to certain voltage ranges.

Q(U) 10 nodes
When it comes to Q(U) with 10 nodes, the reactive power target value is calculated continuously as a function of the grid
voltage. This function ensures that grid support is provided by the reactive power as soon as the voltage actually deviates
from the target voltage. In this case, a characteristic curve is specified which can be used to configure up to 10 nodes,
value pairs for voltage and reactive power. Other parameters allow you to limit functionality and to limit activation to cer-
tain voltage ranges as well as parametrise the transient response.
The positive phase sequence voltage is used to calculate the reactive power target value for three-phase devices.

Description
0 / 1 The reactive power method selected in
the device can only be activated/deac-
tivated indirectly via Sunspec.
0-100 [% ] Setpoint of the reactive power can be
Smax
adjusted depending on the set max-
imum apparent power.
0 – 1000 [s] Specifies the time after which the in-
verter, if it does not receive a new re-
active power specification, reverts to
the previously applicable reactive
power procedure.
If the Timeout is set to 0 seconds, the
transmitted reactive power specifica-
tion is permanently retained, even in
the event of a communication timeout.
Note: when the device is restarted, the
timeout is reset to the default value.
1000 – 120000 Determines the dynamic behaviour in
the event of a change in the active
power set value. The active power is
changed according to a PT-1 character-
istic curve with a settling time of 5 Tau.
NOTE: The settling time is overlaid with
the increasing and decreasing gradient.
