Inverex Fronius Smart Meter 63A-3

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 meter. Together with Fronius Solar. Web, the Fronius Smart Meter presents a clear overview of power consumption. In the Fronius Energy Package storage solution, 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, Fronius Primo, Fronius Eco inverters and the Fronius Data manager 2.0.
