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
supplied with 1 installation location for your own communication devices. In this option, the PowerPlantController
does not include a programmable logic controller. During installation, observe the requirements for each device to be
installed.
The product is not suitable for supplying life-sustaining medical devices. A power outage must not lead to personal
injury.
The product is for use in weather-protected outdoor areas and in indoor areas. The ambient conditions prescribed for
the product must be observed at all times.
The product is intended for use in industrial environments.
All components must remain within their permitted operating ranges and their installation requirements at all times.
Use SMA products only in accordance with the information provided in the enclosed documentation and with the
locally applicable laws, regulations, standards and directives. Any other application may cause personal injury or
property damage.
Alterations to the SMA products, e.g., changes or modifications, are only permitted with the express written permission
of SMA Solar Technology AG. Unauthorized alterations will void guarantee and warranty claims and in most cases
