FRONIUS SMART METER
The bidirectional meter for intelligent
energy management
The Fronius Smart Meter is a bidirectional meter, which optimises self-consumption, records the load curve and controls the various
energy flows. 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 meter.
Together with the Fronius Solar.web, the Smart Meter presents a clear overview of the power consumption. In combination
with the Fronius storage solutions, the device ensures a perfectly coordination of various energy flows, which optimises the
entire energy management. The Fronius Smart Meter is ideally suited for use with the GEN24 Plus and Tauro, as well as all
Fronius inverters with the Fronius Datamanager 2.0.
