Checklist for installation
For installation information, see the following chapters:
1Switch off the power supply before establishing a grid connection.
2Mount the Fronius Smart Meter (see Installation on page (→)).
3Connect automatic circuit breakers or automatic circuit breakers and disconnectors (see Protective circuit on page (→)).
5Mount the current transformers on the conductors. Make sure that the current transformers are pointing in the correct direction. An arrow either points to the load or the source (public grid) (see Connecting the current transformers on page (→)).
6Connect the current transformer and Fronius Smart Meter (see Connecting the current transformers on page (→)).
7Make sure that the current transformer phases match the mains voltage phases (see Connecting the current transformers on page (→)).
8Note down the nominal current of the current transformer for each meter. These values will be required during setup.
9Connect the output terminals of the Fronius Smart Meter to the Fronius inverter (see Connecting the data communication cable to the inverter on page (→)).
10If necessary, set terminating resistors (see Terminating resistors on page (→)).
11Tug on each wire and plug to make sure that they are securely connected to the terminal blocks.
12Switch on the power supply to the Fronius Smart Meter.
13Check the firmware version of the Fronius inverter. To ensure compatibility between the inverter and the Fronius Smart Meter, the software must always be kept up to date. The update can be started via the inverter web page or using Solar.web.
14Set the transformation ratio of the current and voltage transformers (see Setting the transformation ratio of the current and voltage transformers on the Fronius Smart Meter on page (→)).
15If several Fronius Smart Meters are installed in the system, set the address (see "Setting the address" under Setting the address of the Fronius Smart Meter on page (→)).
16Configure and commission the meter (see Commissioning on page (→)).
Installation
The Fronius Smart Meter can be mounted on a 35 mm DIN rail. The housing comprises 4 DUs (division units, max. 72 mm).
Protective circuit
The Fronius Smart Meter 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 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.
- 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.
- Use overcurrent protection rated for max. 63 A.
- To monitor more than one mains voltage, use connected automatic circuit breakers.
- The overcurrent protection must protect the grid terminals marked L1, L2, and L3. In rare cases, the neutral conductor has an overcurrent protection which must simultaneously interrupt neutral and ungrounded lines.
Cabling
WARNING!
Danger from mains voltage.
An electric shock can be fatal.
Switch off the power supply before connecting the mains voltage inputs to the Fronius Smart Meter.
IMPORTANT!
Do not install more than one cable per screw terminal. If necessary, use terminal blocks. The measuring inputs of the current transformers must be grounded on one side as shown in the circuit diagram.
- Wire (rigid): min. 0.05 mm² / max. 4 mm²
- Wire (flexible): min. 0.05 mm² / max. 2.5 mm²
- Recommended torque: 0.5 Nm / max. 0.8 Nm
Connect each voltage cable to the terminal strip as shown in the graphics below.
Selection criteria for current transformers
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 transformer 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 needs 0.3 VA to carry out its measurements. Losses also occur on the outgoing and return leads. The power of the current transformer must be greater than the sum total of the power of the Fronius Smart Meter 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 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 is 0.3 VA.
Line resistance 0.6 VA + self-consumption 0.3 VA = 0.9 VA
→ A current transformer with a rating of 1 VA, 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.
Connecting the current transformers
- Make sure that the current transformers match the voltage phases. Make sure that current transformer L1 measures the current on the same phase that is monitored by voltage input L1. The same applies for phases L2 and L3.
- Make sure that the current transformers are pointing in the correct direction. Observe the data sheet for the current transformer.
Attach the current transformers to the conductor to be measured and connect the current transformer cables to the Fronius Smart Meter. Always switch off the power supply before disconnecting live conductors.
The current transformers are connected to connections 1 and 3; 4 and 6; 7 and 9. If necessary, excessively long cables can be shortened accordingly. Observe the sequence in which the phases are connected. Accurate power measurement is only ensured if the mains voltage phases match the current phases.
Suitable voltage transformers
Suitable voltage transformers: Only voltage transformers with a voltage range from 210 to 440 V (phase - phase) may be used. The voltage transformers must be connected to terminals 2, 5, 8, and 11 at the point of direct voltage measurement.
Connecting the data communication cable to the inverter
Fronius SnapINverter:
Connect the data communication connections of the Fronius Smart Meter to the Fronius system monitoring in the inverter. Several Smart Meters can be installed in the system, see chapter Multi meter system - Fronius SnapINverter on page (→).

1Connect 35 to GND.
2Connect 34 to M1-.
3Connect 33 to M1+.
NOTE!
More information on successful commissioning.
Note the following information about connecting the data communication cable to the inverter.
Use cables of type CAT5 or higher.
The maximum cable length between the Fronius inverter and Fronius Smart Meter is 300 meters.
Use a mutual twisted cable pair for data lines that belong together (D+, D- and M1+, M1-).
If the output cables are close to the grid cabling, use wires or cables that are designed for 300 V to 600 V (never less than the operating voltage).
Use double-insulated or sheathed output cables when they are close to bare conductors.
Use shielded twisted pair cables to avoid faults.
The outputs of the Fronius Smart Meter are electrically isolated from hazardous voltages.
