cos φ constant
In cos φ constant mode, the specified power factor is permanently set by the inverter. In doing so, the reactive power
level is set in line with Q=P*tan ϕ as a function of the power that continuously generates the specified power factor. If
the setting value is changed, the new value is adopted by way of a filter in a muted manner. The settling time is parame-
terizable and is 1s (this corresponds to 5 Tau (according to SunSpec, 3 Tau is ideal) with the transient response of a first-
order filter (PT-1) with a time constant of Tau=200ms. The specified power factor can be configured on the display or by
way of communication via the KACO RS485 protocol and MODBUS/SunSpec.
If the applicable grid code stipulates that the cos-ϕ should react to the target value slower than the configured Tau=200
ms by way of a defined gradient or settling time, this gradient or settling time must be implemented in the system con-
trol.

cos φ(P)
In the cos ϕ (Pn) 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

Description
1000 – 120000 Determines the dynamic behavior in the
event of a change in the active power
set value. The active power is changed
according to a PT-1 characteristic curve
with a settling time of 5 Tau.
NOTE: The settling time is overlaid
with the increasing and decreasing
gradient.
Description
1-0,3 [°] Set the power factor to a certain
%value.
1 – 65524 [% Specifies the dynamic behaviour when
changing the power factor cos ϕ. The
power factor is changed with the set
gradient.
Note: The gradient is overlaid with the
settling time.
1000 – 120000 Set the settling time in case of a sudden
change of the reactive power setpoint
(e.g. due to a voltage jump).
0 – 1000 [s] Sets the time after which the inverter, if
it does not receive a new power factor
specification, falls back to the previously
valid reactive power procedure.
If the Timeout is set to 0 econds, the
trans-mitted power factor specification
is permanently retained, even in the
event of a communication failure.
Note: when the unit is restarted, the
Timeout is reset to the set fallback
time.
