Maximum dynamic gra-
dient frequency
50.22 – 70.5 [Hz]
Minimum dynamic gra-
dient frequency
45 – 50 [Hz]
Dynamic gradient maximum frequency:
If dynamic gradient mode is activated, the gradient is calculated in order
to guarantee a linear power adjustment and reach the maximum charg-
ing power if the frequency rises to the maximum configured frequency.
Dynamic gradient minimum frequency:
If dynamic gradient mode is activated, the gradient is calculated in order
to guarantee a linear power adjustment and reach the maximum feed-in
power if the frequency drops to the minimum configured frequency.
P(f) settling time
200 – 2000 [ms]
Determines the dynamic behaviour in the event of a change in the ac-
tive power limit. In the event of a change in frequency, the active power
is altered subject to a PT-1 characteristic curve using a settling time of 5
Tau.
The settling time is overlaid with the increasing and decreasing gradient.

FRT
Dynamic grid support (Fault Ride Through)
A generator plant’s ability to remain immune to voltage drops and voltage spikes in the supply system is a key element in
establishing a reliable energy supply. Immunity to interference ensures that brief disruptions do not result in a loss of
generation capacity in a larger range of an interconnected grid. Grid support by a fast feeding of residual current also lim-
its the spatial extent of the incident.
With its dynamic grid support by way of immunity, the device has this characteristic. The ability to remain on the grid is
particularly relevant. The protective settings also determine the device’s ability to remain on the grid or not. Protective
settings take the upper hand over the capacity of immunity to interference.

Dynamic grid support by way of immunity to interference
Interference immunity against undervoltage
Voltage drop above the limit curve in can be overcome without the need for shutdown from the grid. The feed-in power
remains constantly within the limits of the maximum continuous current of the inverter.
If a reduction in power occurs, the power is brought back up to the pre-fault level within 100 ms of the voltage returning.
