Configuring Limitation of Active Power Feed-In

With the Data Manager, you can implement grid operator specifications for the limitation of the
active power feed-in from 0% to 100% in your system. The setpoint for limitation of active power
feed-in is specified in percent. The total system power is taken as the reference value. If your grid
operator requires the system not to feed in any active power, you must limit the active power feed-in
to a fixed value of 0% and additionally adjust the preset value for the active power gradient. Thus,
it is possible to limit the active power feed-in to 0% within a few seconds. To compensate for load
step changes and to establish a safety distance to the active power limitation, a negative value can
be set. This achieves a timely limitation of the active power feed-in. The value for the limitation of the
active power feed-in should be adjusted to the load step changes accordingly. No further inverter
settings are necessary.
Responsibility of the system operator for grid management service
specifications
The system operator is responsible for the correctness of the configurations and information on
grid management services and system power. Incorrect settings and specifications can result in
device and system damages.
• Set the grid management service specifications required by the grid operator and laid down
in the standards correctly. Contact the grid operator if necessary.
• Enter correct values for system power. Adjust the values for system power during system
expansions.
• Ensure that all required default values are applied or sent cyclically.
Supported inverters for the limitation of the active power feed-in to 0%
The limitation of the active power feed-in to 0% are only supported by inverters that support
the fallback function. In the event of a communication failure between the product and the
inverter, the inverter is reduced to an output power of 0% during fallback). For more
information see the inverter manual at www.SMA-Solar.com.
Requirements:
☐ The configuration for the active power limitation must be agreed upon with the responsible
grid operator.
