Page 6: General
Together with the Fronius inverter, the Fronius Datamanager and the Fronius data inter- face, the Fronius Smart Meter provides a clear overview of your own power con- sumption. The meter measures the power flow to the loads or to the grid and forwards the information to the Fronius inverter via ModBus RTU/RS485 communication. - Page 7 Positioning at the feed-in point The positioning of the Fronius Smart Meter at the feed-in point.

Page 9: Cabling
Disconnecting devices must be mounted within sight and as close as possible to the Fronius Smart Meter; they must also be easy to use. The disconnecting devices must satisfy the requirements of IEC 60947-1 and IEC 60947-3, as well as all national and local regulations for electrical systems. -
Page 11: Selection Criteria For Current Transformers
The Fronius Smart Meter needs 0.3 VA to carry out its measurements. Losses also occur on the outgoing and return leads. The power of the current trans- former must be greater than the sum total of the power of the Fronius Smart Meter and the leads. The higher the power, the better. -
Page 12: Connecting The Current Transformers
2.2 VA Example The length of the outgoing and return lead (0.5 m each) between the Fronius Smart Meter and the current transformer is a total of 1 m and has a copper cable cross-section of 1.5 mm²; the line resistance is therefore 0.6 VA according to the table above. -
