Fronius Smart Meter TS 63A-3, three-phase meter

The Fronius Smart Meter TS 63A-3 is a bidirectional electric energy meter designed to optimize the consumption of self-produced energy and to record the load profile of a household. Collaborating with Fronius inverters, the Fronius Datamanager device, and the Fronius data interface, the Fronius Smart Meter TS enables a clear presentation of energy consumption data. The meter measures the power flow to appliances or to the grid and communicates this information to Fronius inverters and the Fronius Datamanager device using Modbus RTU/RS485 communication.
