The Fronius Smart Meter described in this document supports the MQTT communication protocol (Message Queuing Telemetry Transport). The Fronius Smart Meter is found by inverters in the same network and can be configured via the user interface of the inverter. In order for this to work, the inverter needs to support MQTT.
This interface is only suitable for communication with Fronius products and not for third-party products.
Connecting the Modbus RTU
Connect the data communication connections of the Fronius Smart Meter IP to the Modbus interface of the Fronius inverter using a CAT 5 STP (Shielded Twisted Pair) or higher data cable.
The Fronius Smart Meter IP can also be connected to the network (LAN / WLAN). This allows software updates to be carried out.
Standard Modbus address & TCP port:- Address: 1
- TCP port: 502
To avoid interference, the terminating resistor must be used (see chapter Setting the Modbus RTU terminating resistor on page (→)).
If a battery is installed in the system, the BIAS switch must be set (see chapter Set Modbus RTU BIAS on page (→)).
Further settings are necessary on the user interface of the inverter and the Fronius Smart Meter IP (see Advanced settings).
IMPORTANT!
A loose wire can disable an entire area of the network. The data communication connections of the Fronius Smart Meter IP are electrically isolated from hazardous voltages.
Observe the following information on connecting the data communication cable to the inverter.
- Use a shielded CAT 5 STP (Shielded Twisted Pair) or higher data cable to avoid interference.
- Use a mutual twisted cable pair for corresponding data lines (D+/D-, M1+/M1-).
- If the data lines are laid close to the mains cabling, cables or wires that are designed for 300 to 600 V must be used (never less than the operating voltage).
- Use double-insulated or sheathed data lines when they are close to bare conductors.
- Two wires can be installed in each terminal; the wires are twisted first, inserted into the terminal, and tightened.

Connecting current transformers
Suitable current transformers
It is recommended to use Fronius CT current transformers (item numbers 41,0010,0104 / 41,0010,0105 / 41,0010,0232). In order to ensure problem-free operation of the Fronius Smart Meter IP 5kA-3 and accurate measurement results, all connected current transformers must meet these requirements:
- The current transformer must generate 333 mV at nominal current. The nominal current of the current transformers is specified in the current transformer datasheet.
- Do not use current transformers with 1 ampere or 5 ampere output current.
- Observe the maximum input current according to the current transformer datasheets.
- Only use Rogowski coils with integrators. Failure to use integrators will result in erroneous measurement results.
- Folding and rigid current transformers can be installed. Rigid current transformers often have better performance and accuracy values. Folding current transformers have a split core and can be opened for attachment to the conductor and installed in a system without voltage interruption.
CAUTION!
Danger of electric shock due to unintentional opening of folding current transformers
This can result in severe injury and damage to property.
Switch off the power when working on the current transformers.
Attach plastic cable ties to the current transformer to prevent unintentional opening.

Connecting the current transformers
1Make sure that the current transformers match the live 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. This is the only way to display correct measured values.
2Make sure that the current transformers are pointing in the correct direction.
NOTE!
Observe direction information when installing the current transformers
Negative power values occur when the current transformers are connected incorrectly.
Observe the data sheet and the marking on the current transformer (arrow indicates the direction to the load or to the public grid)
Check the correct position of the black and white cable.
3Note down the nominal current of the current transformer for each meter. These values will be required for commissioning.
4Attach the current transformers to the conductor to be measured and connect the current transformer cables to the Fronius Smart Meter IP 5kA-3.
WARNING!
Danger from mains voltage
An electric shock can be fatal.
Switch off the power supply before disconnecting live conductors.
5Connect the current transformers to the terminals CT1 (white / black), CT2, and CT3. Excessively long cables can be shortened accordingly. Observe the sequence in which the phases are connected.
6Route the mains conductors through the current transformers (see Cabling).
NOTE!
Cable length of the current transformers
Cables that are too long can have a negative effect on the measuring accuracy.
If a cable extension is necessary, use a shielded 0.34 to 1.5 mm2 (AWG 22-16) CAT 5 STP (Shielded Twisted Pair) cable rated for 300 V or 600 V (higher than the operating voltage).
NOTE!
Unusual measured values on unused phases
If unusual measured values occur on unused phases, bypass the unused current transformer inputs.
To do so, for each unused current transformer, connect the terminal marked with a white dot to the terminal marked with a black dot using a short cable.

The meter aggregation function aggregates the measured values of a maximum of six Fronius Smart Meter IP 5kA-3. A higher-level Fronius Smart Meter IP 5kA-3 serves as the primary Smart Meter and recognizes the secondary Fronius Smart Meter IP 5kA-3.
The prerequisites for this are:- The primary Smart Meter and all secondary Smart Meters are Fronius Smart Meters IP 5kA-3.
- All Smart Meters are in the same network.
- All Smart Meters have the same software version installed.
- The energy values
- The active power
- The reactive power
- The apparent power
The aggregation of the measured values does not take into account any power loss.
The user interface of the inverter displays the primary Smart Meter and the secondary Smart Meters. The data interfaces used display the measured values. The aggregated measured values are made available via:
- Modbus TCP Port 1502
- Modbus RTU ID 1
- MQTT
The measured values of the primary Smart Meter are provided via either Modbus TCP port 502 or Modbus RTU ID 2.
