SMA ModBus Gateway
SMA smart web server for modbus interface, MODBUS-GATEWAY
The Modbus Gateway solution offered by SMA is for PV plants with Energy Management Systems (EMS) where the plant operators require inverter operating data via Modbus protocol. SMA utilizes the i.LON SmartServer to provide this functionality. The SmartServer polls the Sunny Central inverter channels via SMA Data 1 protocol and makes this data available to EMS Modbus enabled devices.
The SmartServer is capable of polling all of the inverter channels and providing a subset of these values which are of greatest interest to the PV plant operator.
