The SMA Cluster Controller is the ideal system solution for decentralized large-scale PV plants when combined with the
highly efficient SMA string inverters. The SMA Cluster Controller offers reliable monitoring and control of up to 75 string inverters thanks to the Ethernet-based Speedwire fieldbus and the high-performance dual-core processor. Plant operators receive advantages such as the optimum data transmission rates for plant monitoring and a fast processing of the measured values, status updates, and plant control commands. Furthermore, the many different connection options for the sensors allow you to evaluate the plant power more precisely. In addition to the status updates, the relevant plant power can be viewed using the Sunny Portal with a variety of features.
