10.9.3 Active Power by Frequency P(f)
Menu 512 Power/Frequency
Description
Allows the statistics to be reset. The currency and credit per kWh
can also be congured.
This function alters the fed active power depending on the grid
frequency. If a starting frequency is exceeded, the fed active power
is limited. If a stopping frequency is exceeded, the active power is
no longer fed.
Behavior as per VDE AR N 4105 is described below.
Variant 1: The grid frequency alters between f

and f
Stop
.

Once the grid frequency exceeds the value f

, the value of the
active power P

being fed at this moment is automatically saved
and active power limiting is activated.
As long as the grid frequency stays above f
Start
and under f
Stop
, the
fed active power value runs along the gradients: Active power drops
with increasing grid frequency and increases with decreasing grid
frequency.
Variant 2: The grid frequency exceeds f

When the grid frequency exceeds f
Start
but then remains under f
Stop
,
the solar inverter behaves as described in variant 1.
However, as soon as the grid frequency exceeds f
Stop
, the active
power feed is stopped.
Active power feed will resume once the grid frequency falls below
f
Start
. Once resumed, the active power will increase by 10% per
minute.
