The perfect solution for decentralized PV power plants in terms of functionality and flexibility: Speedwire as a new Ethernet-based fieldbus offers top-notch performance right down to the inverter. The system can be controlled using the SMA Cluster Controller, the digital interface or the Modbus TCP, guaranteeing optimum network management and compliance with all standards and regulations. The line topology allows you to operate up to 75 inverters per SMA Cluster Controller. The system can be managed efficiently, and this solution offers powerful monitoring and alarm features. Furthermore, the simple �daisy chain� wiring offers flexibility and saves costs.
