On January 29th, 2013, SMA Solar Technology AG (Niestetal, Germany) announced that it has introduced the new SMA Cluster Controller to monitor and control of decentralized large-scale photovoltaic (PV) power plants.

The SMA Cluster Controller offers reliable monitoring and control of up to 75 string inverters using an Ethernet-based Speedwire fieldbus and a high-performance dual-core processor.

The high-performance bus system with 100 Mbit/s technology provides advantages for PV plant operators, such as optimum data transmission rates for plant monitoring and fast processing of measured values, status updates, and plant control commands, the company states.

Additionally, the connection options for the sensors enable plant operators to evaluate nominal plant power more precisely. In addition to the status updates, the nominal plant power can be viewed using Sunny Portal, SMA notes.

The system solution incorporating Cluster Controllers, the Speedwire fieldbus, and the PV farm management system allows flexible changes of the power output of PV plants. The modular system can be expanded as needed because additional clusters can be added conveniently.
