SMA CLUSTER CONTROLLER User Manual

• Select the group Settings of analog inputs.
• In the field Failure tolerance time, enter the desired time interval.
• In the field Initial value input signal, enter the desired value.
• In the field Final value input signal, enter the desired value.
• In the field Start setpoint reactive power, enter the desired value.
• In the field End setpoint reactive power, enter the desired value.
8. When using the digital inputs, set the status configuration:
• Select the group Status configuration.
• Depending on the number of digital inputs used in the column Active, activate the
selection field of the status to be configured in each case.
• In the column Reactive power, enter the desired value for the status to be configured in
each case.
9. Make the settings for the fallback (see Section13.5, page70).
13.4.2 Controlling Reactive Power via the Setpoint "cosPhi"
If you select the displacement power factor cosφ as the reactive power setpoint, the cosine function
of the phase shift angle between the current and the voltage is used as setpoint.
Input signals up to 21mA possible
For an analog signal source, the ClusterController classifies input signals as valid up to a
maximum of 21mA. This enables intentional overload to ensure that the maximum setpoint is
reached.
Requirements:
☐ The configuration for the reactive power setpoint must be agreed upon with the responsible
grid operator.
☐ The required parameter for the reactive power setpoint must be configured in the inverter (see
Section13.2, page63).
Procedure:
1. Log into the ClusterController as Installer.
2. In the system tree, select the ClusterController and select the menu Grid management
services in the device menu.
3. Make the general settings:
• Select the parameter group General settings > System control.
• Select [Edit].
• In the drop-down list Operating mode, select the entry Open-loop control.
• If you are using digital or analog inputs, enter the desired time interval in the field Time
interval for the output value.
4. Select the parameter group Reactive power and select [Edit].
5. Make the basic settings in the group Basic settings:
