Lock-in time
0 – 60 [s]
Length of time that the active power must remain below the lock-in
power level before control is deactivated.
Lock-out time
0 – 60 [s]
Length of time that the active power must remain below the lock-out
power level before control is deactivated.

If the voltage switches from a characteristic curve section with Q=0 to a
characteristic curve section with Q≠0 under active control, then the re-
active power setting process is delayed by the set dead time. Once the
dead time has expired, the control circuit is no longer subject to a delay
and the set transient time determines the transient behaviour.

In addition to configuring the dynamic behaviour using the transient
time corresponding to a first-order filter, the reactive power setting can
be determined by a maximum gradient - this means the maximum
change in the reactive power per time period.

Min. cos-phi Q1 - Min.
cos-phi Q4
In the event of a significant voltage deviation, the maximum reactive
power adjustment range can be limited by a minimum cos ϕ in order to
prevent an excessive reactive power supply and, as a result, a significant
reduction in the maximum active power that can be fed in.
Q1
Minimum cos ϕ in over-excited operating mode (in-feed).
Q4
Minimum cos ϕ in under-excited operating mode (in-feed).
Q2
Minimum cos ϕ in over-excited operating mode (charge).
Q3
Minimum cos ϕ in over-excited operating mode (charge).
Priority mode
Q priority | P priority
P priority can be selected as an alternative to the standard setting Q pri-
ority. When it comes to P priority, the reactive power adjustment range
is limited subject to the limited apparent power of the inverter and the
active power that is currently available and fed in.
Active curve
1 – 4
Up to four characteristic curves can be configured independently and
one of them can be activated for regulation each time.
Reset the curve
Reset active curve to the factory setting, depending of the country set-
ting.
Number of nodes
2 – 10
Specify the number of nodes for the Q(U) characteristic curve.
1st node … 10th node
0V - Max. voltage in
continuous operation
Voltage of the node in volts.
The voltage values of the nodes must increase continuously. At voltages
below the 1st node and voltages above the last node, the reactive
power value of the 1st or last node is used each time.
1 – 0.3
Reactive power of the node as a percentage of the maximum power
Over-excited | under-
excited
Reactive power mode Under-excited relates to inductive load, over-ex-
cited relates to capacitive load.

Active power regulation
10.2.1 P target value
The function “P target value” is integrated into the MPP tracking of the inverter on all PV inverters. The P target
value is continuously re-calculated on the basis of the MPP tracking algorithm.
