The power related control mode cosφ(P) controls the cosφ of the output as a function of the
active power output.
There are four coordinate points that can be configured. The coordinate points are the active
power as a percentage of Pn and the displacement factor cosφ.

The threshold voltage for deactivating the active power
response to overvoltage or disconnecting the inverter
from the grid.
The threshold voltage for deactivating the active power
response to overvoltage after the voltage reducing.
Reset voltage does not work in the mode “Act. Power as a
percentage of P
N, Linear”.
Reducing the active power in percentage of P
N or PM
when the voltage rise to Ustop.
The delay time for activating active power response to
overvoltage after the voltage over U
start. An intentional
delay shall be programmable to adjust the dead time to a
value between the intrinsic dead time and 2s.
The delay time that the active power can increase after
the voltage below U
reset.
