Power Reducer Box

Feed-in management for large-scale PV plants

With the Power Reducer Box, SMA delivers a solution for large PV plants that must take part in feed-in management. It allows the network operator to remotely control the plant performance. It achieves this by translating the transmitted setpoint values into control commands for the Sunny WebBox, which forwards them to the inverters. During this process, each change of status is logged twice, once in the Power Reducer Box and once in the Sunny WebBox. In addition, the network operator’s requirements are visualized in Sunny Portal, informing the plant operator immediately.
