The Fronius Smart Meter TS is a fixed piece of equipment for public grids of TN/TT systems and records self-consumption and/or individual loads in the system. The Fronius Smart Meter TS is required for systems with a battery storage system and/or a Fronius Ohmpilot installed for communication between the individual components. The installation is carried out on an indoor DIN rail with corresponding back-up fuses, which are adapted to the cable cross-sections of the copper conductors and to the maximum current of the meter. The Fronius Smart Meter TS must only be operated in accordance with the specifications in the enclosed documentation and in accordance with local laws, regulations, provisions, standards and within the limits of technical possibilities. Any use of the product other than as described in the intended use shall be deemed to be not in accordance with the intended purpose. The available documentation forms part of the product and must be read, observed and kept in good condition. It must also be accessible at all times at the place of installation. The available documents do not replace regional, state, provincial or national laws, or regulations or standards that apply to the installation, electrical safety and use of the product. Fronius International GmbH assumes no responsibility for compliance with or non-compliance with these laws or regulations in connection with the installation of the product.
Interventions on the Fronius Smart Meter TS, e.g. modifications and alterations, are not permitted. Unauthorised interventions will void the warranty and warranty claims and, as a rule, void the user's authority to operate the equipment. The manufacturer shall not be liable for any damage resulting from such use.
Reasonably foreseeable misuse:
The Fronius Smart Meter TS is not suitable for the supply of life-sustaining medical devices or for the billing of subtenants.

The Fronius Smart Meter TS can be installed in the following positions in the system:
Positioning at the feed-in point:
Positioning at consumption point:
For use as a secondary meter to measure individual loads and producers, see chapter Multi-meter system - Fronius SnapINverter on page (→).
The Fronius Smart Meter TS has accuracy class 1 when measuring active energy (EN IEC 62053-21) in the voltage ranges 400 - 480 VLL or 230 -277 VLN. Within the voltage ranges 173 - 400 VLL or 100 - 230 VLN the accuracy class is 2 (active energy according to EN IEC 62053-21, reactive energy according to EN IEC 62053-23). For further details see Technical data on page (→).
The Fronius Smart Meter TS can be mounted on a 35 mm DIN rail. The housing comprises 3 modules according to DIN 43880.
The Fronius Smart Meter TS is a hard-wired device and requires a disconnecting device (circuit breaker, switch or disconnector) and overcurrent‑protection (automatic‑circuit breaker).
The Fronius Smart Meter TS consumes 10 - 30 mA, the nominal capacity of the disconnecting devices and the overcurrent‑protection is determined by the wire thickness, the mains voltage and the required breaking capacity.
IMPORTANT!
An auxiliary power supply is required to operate the Fronius Smart Meter TS. The fuse (F) must comply with the national standards and guidelines as well as the dimensions of the conductors.
IMPORTANT!
Always switch off the power supply before connecting the mains voltage inputs to the Fronius Smart Meter TS.
The measuring inputs of the current transformers must be earthed on one side as shown in the circuit diagram.
Connect each voltage cable to the terminal strip as shown in the graphics below.
General
Do not use current transformers with a voltage output.
Current transformers are directional. If they are mounted backwards or with swapped wires, the measured power will be negative.
Primary current
Maximum current per phase. A current converter with a primary current greater than the maximum expected current per phase should be selected. The closer the expected current is to this value, the more precise the measurement will be.
Secondary current
The current transformer must supply alternating current at a nominal current of 1 or 5 A. The nominal values for the current transformer are listed in the current transformer data sheet.
Power
The Fronius Smart Meter TS needs 0.5 VA to carry out its measurements. Losses also occur on the outgoing and return leads. The power of the current converter must be greater than the sum total of the power of the Fronius Smart Meter TS and the leads. The higher the power, the better.
Line resistances at different cross-sections (copper wires) | ||||||
---|---|---|---|---|---|---|
Secondary current | Cross-section | Line resistances at different lead lengths (outgoing and return lead) | ||||
0.5 m | 1.0 m | 2.5 m | 5 m | 10 m | ||
5 | 1.5 | 0.3 VA | 0.6 VA | 1.5 VA | 2.9 VA | 5.8 VA |
5 | 2.5 | 0.2 VA | 0.4 VA | 0.9 VA | 1.8 VA | 3.6 VA |
5 | 4 | - | - | 0.6 VA | 1.1 VA | 2.2 VA |
Example
The length of the outgoing and return lead (0.5 m each) between the Fronius Smart Meter TS 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. The self-consumption of the Fronius Smart Meter TS is 0.5 VA.
Line resistance 0.6 VA + self-consumption 0.5 VA = 1.1 VA
→ A current transformer with a rating of 1.5 VA, 5 VA or higher is suitable here.
Accuracy class
Use Class 1 or better (Class 0.5 / 0.2, etc.). Class 1 is equivalent to a deviation of ± 1% of the secondary current at maximum power.
Mounting
Rigid or hinged
"Rigid" is usually cheaper with better power and accuracy values. Hinged current transformers can be opened for attachment to the conductor. To prevent it being opened inadvertently, a plastic cable tie can be secured to the current transformer. Hinged current transformers can be installed in a system without interrupting the voltage.
Only voltage transformers with a voltage range from 220 to 480 V (phase - phase) and from 100 to 277 V (phase - neutral conductor) may be used. The voltage transformers must be connected to terminals 1, 2, 3 and N at the point of direct voltage measurement.
Connect the data communication connections of the Fronius Smart Meter TS to the Modbus interface of the Fronius inverter using a network cable (type CAT5 or higher).
Several Smart Meters can be installed in the system, see chapter Multi-meter system - Fronius SnapINverter on page (→).
To avoid interference, the terminating resistor must be used (see chapter Connecting the terminating resistor on page (→)).

If several Fronius Smart Meter TS are installed, a separate address must be set for each (see Setting the address on the Fronius Smart Meter TS on page (→)). The primary meter is always assigned address 1. All the other meters are numbered consecutively with the address range from 2 to 14. Different Fronius Smart Meter power categories can be used in combination.
IMPORTANT!
Max. Use 3 secondary meters in the system. To avoid interference, it is recommended to install the terminating resistors according to chapter Connecting the terminating resistor on page (→).
