1.7 Explanation of Used Terms
Term Explanation
Genset Electric generator with combustion engine
Hybrid system System for the control of energy flows based on a programmable logic controller
(e.g. SMAHybridController or Power Plant Manager)
Various energy sources can be integrated into a hybrid system (e.g. PV power
plant, genset or battery-storage system).
Redundancy Redundancy is the additional presence of a functionally identical or comparable
resource of a technical system when this resource is normally not needed during
fault-free operation. An example of this is a redundant system controller such as
the SMAPowerPlantManager. This additional resource increases the reliability
and thus the availability of the system.
Programmable Logic Controller
(PLC)
A programmable logic controller is a digitally operating, electronic system. It
uses programmable memory for the internal storage of user-oriented instructions
to control functions and various types of machines or processes through digital or
analog inputs and outputs.

2 Safety
2.1 Intended Use
The PowerPlantManager is the central communication unit for monitoring, management and grid-compliant power
control of large-scale PV power plants with PV inverters, battery inverters and genset devices. System components and
systems are integrated into the SMA infrastructure via the PowerPlantManager. This includes energy generators and
loads, I/O systems and energy meters. The PowerPlantManager supports communication with up to 200 devices.
The PowerPlantManager is responsible for power control and energy management in large PV and hybrid systems.
Both central inverters and decentralized string inverters, which are monitored and controlled by communication
gateways, can be connected in the system.
In the PowerPlantManager, the setpoints for grid management services are received and compared with the values
measured at the point of interconnection. Based on this comparison, the PowerPlantManager calculates the required
control values and transmits these values to the connected devices. The PowerPlantManager can receive setpoints in
digital and analog form and via Modbus/TCP protocol. The setpoints of a superordinate SCADA system are
transmitted via Modbus/TCP protocol. Setpoints from the grid operator can also be received via an optionally
integrated protocol converter in accordance with IEC 60870 5 101, IEC 60870 5 104, IEC 61850 or DNP3.
The values measured at the point of interconnection by the power analyzer are processed by a power analyzer and
retrieved by the PowerPlantManager. As an alternative, measuring modules of the programmable logic controller
integrated in the PowerPlantManager are used to receive the measured values at the point of interconnection. In
order to set up a redundant system, 2 PowerPlantManagers must also be used in a system. Both
PowerPlantManagers must support the redundancy function and have a valid license for redundant operation.
The PowerPlantManager is operated via the integrated user interface. Via the user interface, you can set parameters,
configure functions, view actual values and read out error messages.
You also have the option to control and monitor one or multiple systems with a PowerPlantManager via SunnyPortal
powered by ennexOS. SCADA systems can also be used for system management and can exchange high-resolution
data with the PowerPlantManager for this purpose.
If you have selected the option "Customer Installation Location" in the option code, the PowerPlantController is

This system overview shows an example of the setup of a large-scale PV power plant with 2 PowerPlantManagers
(for communication via Internet, see Section4.3.1, page16).
In this system, one of the two PowerPlantManagers always has the active role and thus controls the entire plant. The
other PowerPlantManager is redundant and monitors the active PowerPlantManager. If the active system controller
can no longer control the system, the previously redundant system controller takes over active control without
interruption and within the shortest possible time. The failed system controller is automatically restarted to restore the
redundant state.
If it is impossible to restart the failed system controller, the system generates a system status message, which requests
that this system controller be replaced. The system continues to operate securely by using the intact system controller
(fail-safe operation).

Figure 5: System overview of a large-scale PV power plant with 2 PowerPlantManagers and 1 Redundancy Connector (example)
This system overview shows an example of the setup of a large-scale PV power plant with 2 PowerPlantManagers
with the Redundancy Connector (for communication via Internet, see Section4.3.1, page16). Joint operation of both
PowerPlantManagers, including the role change in case of a fault, works the same way as for a large-scale PVpower
plant with 2PowerPlantManagers.
For the use of digital inputs and outputs, such as with a medium-voltage switchgear, the RedundancyConnector is
recommended. The RedundancyConnector ensures a complete decoupling of the digital inputs and outputs. With this
decoupling, an active PowerPlantManager that keeps a digital output closed, can be replaced by the redundant
PowerPlantManager. After this replacement, the now active PowerPlantManager can open and close this output
regardless of the previous switch status. The system continues to operate securely by using the active system controller
(fail-safe operation) just as with a large-scale PV power plant with 2 PowerPlantManagers. Only the active
PowerPlantManager controls the Redundancy Connector.

Figure 6: System overview of a large-scale PV power plant with a PowerPlantManager and SMADataManager (example)
This system overview shows an example of the setup of a large-scale PV power plant with a PowerPlantManager and
an SMADataManagerL (for communication via Internet, see Section4.3.1, page16). The PowerPlantManager
and the SMADataManagerL work together according to the master-slave principle. During this process, the
PowerPlantManager is the master, SMADataManagerL is always a slave. Multiple instances of
SMADataManagerL can be connected as slaves to one PowerPlantManager.
