Fronius Datamanager

The Fronius Datamanager is the communications centre for Fronius inverters. Whenever it is connected to the internet via a LAN or WLAN, the Fronius Datamanager sends the PV system values directly to the Fronius Solar.web online portal.

The integrated Modbus RTU SunSpec, Modbus TCP SunSpec and Fronius Solar API (JSON for actual values) interfaces allow Fronius inverters to be seamlessly linked to third-party systems and run in parallel with Fronius Solar.web.

Fronius Smart Meter UL

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 within the home. In the Fronius storage solutions, 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 GEN24 or Fronius SnapINverters and the Fronius Datamanager 2.0.

  • Versions for single or three phase.
  • Suitable for Export Limitation
  • Can be used with Current Transformers (CTs)

Safety Note: CTs must never be operated open-circuit (secondary coil wires disconnected) once installed, whilst on a current-carrying conductor, as dangerously high voltages may occur under these circumstances.

Fronius Smart Meter

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 perfect coordination of various energy flows, which optimises the entire energy management.

The Fronius Smart Meter is ideally suited for use with the GEN24 Plus, as well as all Fronius inverters with the Fronius Datamanager 2.0.

TS 100A-1 & TS 65A-3 can be used for export limitation and are suitable for direct connection only.

Fronius Ohmpilot

Used to intelligently control heating elements for providing hot water in boilers and buffer storage tanks, but can also be used for infrared heating or towel radiators.
As soon as surplus energy is available, this is fed directly to a heating load increasing self consumption from a PV system.

  • Continuously adjustable regulation from 0 to 9 kW
  • Single or three phase
  • Easy installation
  • Compatible with other heat sources, such as heat pumps
  • Protection against legionella
  • Dynamic power reduction enables zero feed-in
  • A Fronius Smart Meter is also required for operation.
