Modbus
The product is equipped with a SunSpec Modbus interface. You will find a list of the supported SunSpec Modbus registers at www.SMA-Solar.com.
The Modbus interface is activated by default and the communication port 502 set.
Communication via SunSpec Modbus is the condition for the operation of the inverter with the SMA Data Manager. The SMA Data Manager enables monitoring and controlling of the inverter in Sunny Portal. For this, the inverter must be registered via SunSpec Modbus in the SMA Data Manager (see manual of the SMA Data Manager).
The Modbus interface of the supported SMA products is designed for industrial use – via SCADA systems, for example – and has the following tasks:
Communication of the inverter with the SMA Data Manager
Remote query of measured values
Remote setting of operating parameters
Setpoint specifications for system control
