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.
NOTICE
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.
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.
☐ There must be an appropriate energy meter installed at the grid-connection point within the
system.
Procedure:
1. Log into the user interface of the DataManager.
2. Select the menu item Grid management service in the menu Configuration.
3. Select the button Configuration and activation in the Active power row.
☑ The installation assistant will open.
4. Confirm every step with [Continue]
5. Select the operating mode Closed-loop control.
6. Select the signal source Manual control.
7. Enter the value 0 in the field Active power setpoint:
• To set the limitation of the active power feed-in to 0% of the total system power, for
example, enter the value 0 in the Active power setpoint field.
• To set the limitation of the active power feed-in to -10% of the total system power, for
example, enter the value -10 in the Active power setpoint field.
8. Activate the switch to adjust the modification speed of the setpoint.
9. Enter the value 1 in the field Setting time
