Fronius Smart Meter 50kA-3


Meters for connection to photovoltaic systems

With the connection of an energy meter to the photovoltaic system, many new applications can be realized. For Example it is possible to analyze the energy consumption of your home or business accurately. The values can be used for energy management as well, in order to increase your self-consumption rate and self-sufficiency. Due to the fast and accurate measurement of our meters, they are also perfectly suited for dynamic feed-in management.

The bidirectional meter for recording power consumption in the home 

The Fronius Smart Meter is a bidirectional meter which optimises self-consumption and records the household‘s load curve. Thanks to highly accurate measurements and rapid communication via the Modbus RTU interface, dynamic feed-in control when feed-in limits are imposed is faster and more accurate than with the S0. Together with Fronius Solar.web, the Fronius Smart Meter presents a clear overview of power consumption within the home. In the Fronius Energy Package storage solution based on the Fronius Symo Hybrid, the Fronius Smart Meter provides perfectly coordinated management of the various energy flows and optimises overall energy management. The Fronius Smart Meter is ideally suited for use with the Fronius Symo, Fronius Symo Hybrid, Fronius Galvo inverters and the Fronius Datamanager 2.0.
