SMA CLUSTER CONTROLLER User Manual

• In the drop-down list Signal source, select the desired signal source. Note that the
desired Modbus server must be activated in the ClusterController when you are using the
Modbus (see Section12.1, page60).
• In the drop-down list Predefined Quantity, select the setpoint cosPhi.
6. When using the digital inputs, make the settings for the digital inputs:
• Select the group Settings of digital inputs.
• In the field Failure tolerance time, enter a value above 1 if possible. This prevents e.g.
a brief, simultaneous activation of two relays of a ripple control receiver during a
ClusterController status change being classified as an invalid status.
7. When using the analog inputs, make the settings for the analog inputs:
• 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 CosPhi start setpoint, enter the desired value.
• In the drop-down list Excitation type, select the desired excitation type.
• In the field CosPhi end setpoint, enter the desired value.
• In the drop-down list Excitation type, select the desired excitation type.
8. When using the digital inputs, set the status configuration:
• Select the group Status configuration.
☑ The columns cosPhi and Excitation type are also displayed.
• 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 cosPhi, enter the desired value.
• In the drop-down list Excitation type, select the desired excitation type.
9. Make the settings for the fallback (see Section13.5, page70).
13.5 Making Settings for Fallback
Fallback is an operating mode in the ClusterController used for grid management services.
There are two types of fallback.
• Fallback in case of missing or invalid external setpoint
• Fallback in case of failure of Speedwire communication between ClusterController and
inverters
Fallback in Case of Missing or Invalid External Setpoint
This type of fallback is an operating mode containing setpoints which are implemented by the
ClusterController if it classifies a setpoint as invalid or does not receive a setpoint within a
configurable time. The ClusterController classifies a setpoint as invalid if there is no configuration
for the setpoint available in the ClusterController or if the setpoint is not within the value range
configured in the ClusterController. In the event of an invalid or missing setpoint, the fallback
prevents the ClusterController from continuing to transmit to the inverter setpoints which may no
