General
Device description
The Fronius Smart Meter is a bidirectional electricity meter for optimizing selfconsumption and recording the household’s load characteristic curve. Together with the Fronius inverter, the Fronius Datamanager and the Fronius data interface, the Fronius Smart Meter provides a clear overview of your own power consumption.
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.
CAUTION!
Observe and follow the safety instructions!
Failure to observe the safety instructions will result in damage to persons
and equipment.
- Switch off the power supply before establishing the mains connection.

Installation
Installation Checklist
See the sections referenced below for installation details.
-
Turn off power before making line voltage connections.
-
Mount the Fronius Smart Meter (see Mounting on page 9).
-
Connect circuit breakers or fuses and disconnects (see Circuit Protection on page 10).
-
Connect the line voltage wires to the meter‘s terminal block (see Line Wiring on page 10).
-
Mount the Current Transformers (CTs) around the line conductors. Make sure the CTs face the correct direction. An arrow might indicate either the load or the source (public grid) (see Connect Current Transformers on page 13).
-
Connect the twisted white and black wires from the CTs to the terminal block on the meter, matching the wire colors to the white and black dots on the meter label (see CT Wiring on page 13).
Check that the CT phases match the line voltage phases (see Connect Cur-rent Transformers on page 13). -
Record the CT rated current for each meter, because it will be required dur-ing setup.
-
Connect the output terminals of the Fronius Smart Meter to the monitoring equipment (see Connecting data communication cables to inverters on page 14).
-
If necessary set terminating resistors (see Terminating Resistors on page 16).
-
Check that all the wires and plugs are securely installed in the terminal blocks by tugging on each wire.
-
Turn on the power to the Smart Meter.
-
Verify that the LEDs indicate correct operation. If there is a consumption of power and all generated power sources are turned off, then the LEDs from the used phases should flash green (see Power Status LEDs on page 30).
-
Check your Fronius System monitoring software. In order to ensure compatibility between the inverter and the Smart Meter, software must always be kept up-to-date. The update can be started via the inverter website or via Solar.web.
-
Set CT-Ratio and Grid Type on the web interface of the Fronius Datamanager in Settings – Meter – Settings (see Commissioning on page 23).
Mounting
The Fronius Smart meter has two mounting holes spaced 5.4 in. (137 mm) apart
(center-to-center). These mounting holes are normally obscured by the
detachable screw terminals. Remove the screw terminals to mark the hole
positions and mount the meter. Self-tapping sheet metal screws are included.
Do not over-tighten the screws, as long-term stress on the case can cause
cracking.
Circuit Protec-tion
The Fronius Smart Meter is considered “permanently connected equipment“ and
requires a disconnect means (circuit breaker, switch or disconnect) and
overcur-rent protection (fuse or circuit breaker).
The Fronius Smart Meter only draws 10-30 mA, so the rating of any switches,
dis-connects, fuses and / or circuit breakers is determined by the wire gauge,
the mains voltage and the current interrupting rating required.
-
The switch, disconnect or circuit breaker must be within sight and as close as practicable to the Fronius Smart Meter and must be easy to operate.
se circuit breakers or fuses rated for 20 amps or less. -
Use ganged circuit breakers when monitoring more than one line voltage.
-
The circuit breakers or fuses must protect the mains terminals labeled L1, L2 and L3. In the rare cases where neutral has overcurrent protection, the over-current protection device must interrupt both neutral and ungrounded con-ductors simultaneously.
-
The circuit protection / disconnect system must meet IEC 60947-1 and IEC 60947-3, as well as all national and local electrical codes.
Line Wiring
- Always turn off power before connecting the line voltage inputs to the Froni-us Smart Meter.
- For the line voltage wires, 16 to 12 AWG stranded wire, type THHN, MTW or THWN, 600 V are recommended.
- Do not place more than one wire per screw terminal; use separate wire nuts or terminal blocks if needed.
- Verify that the line voltages match the line-to-line and line-to-neutral values printed in the white box on the front label.
Connect each conductor to the appropriate phase; also connect ground and
neutral (if applicable). The neutral connection “N“ is not required on delta
mod-els but we recommend connecting it to ground if neutral is not present.
The screw terminal can handle wire up to 12 AWG. Connect each voltage line to
the green terminal block as shown in the following figures. After the voltage
lines have been connected, make sure both terminal blocks are fully seated in
the Fronius Smart Meter. When power is first applied, check that the LEDs
behave normally. If you see LEDs flashing red-green-red-green, the voltage is
too high for this model, so dis-connect the power switch immediately! Single-

Connect Current Transformers
The current transformer must generate 333.33 millivolts AC at rated current. See the current transformer data sheets for CT ratings (Fronius CT, 41,0010,0104 / 41,0010,0105 / 41,0010,0232 / 41,0010,0233).
- Do not use ratio or current output such as 1 amp or 5 amp output models!
- See the CT data sheets for the maximum input current ratings.
- Be careful to match the CTs with the voltage phases. Make sure the CT L1 is measuring the current on the same phase being monitored by the L1 voltage input and the same for phases L2 and L3. Use the supplied colored labels or colored tape to identify the CT leads.
- To minimize current measurement noise, avoid extending the CT wires, espe-cially in noisy environments. If it is necessary to extend the wires, use twisted pair cable 22 to 14 AWG, rated for 300 V or 600 V (not less than the service voltage) and shielded if possible
- Make sure the CTs face the correct direction. An arrow might indicate either the load or the source (public grid)
- If you see strange readings on unused phases, jumper the unused CT inputs: for each unused CT, connect a short cable from the terminal marked with a white dot to the terminal marked with a black dot.
Install the CTs around the conductor to be measured and connect the CT leads to the Fronius Smart Meter. Always turn off power before disconnecting any live conductors. Put the line conductors through the CTs as shown in the previous section. CTs are directional. If they are mounted backwards or with their white and black wires swapped the measured power will be negative. The status LEDs indicate negative measured power by flashing red. Split-core CTs can be opened for installation around the conductor. A nylon cable tie may be secured around the CT to prevent inadvertent opening.
CT Wiring
The current transformers connect to the six position black screw terminal
block. Connect the white and black CT wires to the Fronius Smart Meter
terminals marked CT L1, CT L2 and CT L3. Excess length may be trimmed from the
wires if desired. Connect each CT with the white wire aligned with the white
dot on the label and the black wire aligned with the black dot. Note the order
in which the phases are connected, as the line voltage phases must match the
current phases for accurate power measurement.

Operation
Power Status LEDs
The three status LEDs on the front of the Fronius Smart Meter can help indicate correct measurements and operation. The “L1”, “L2”, and “L3” on the diagrams indicate the three phases:
Normal Startup
The Fronius Smart Meter displays the following startup sequence whenever power
is first applied.
Consuming Power
Any phase with the LEDs flashing green is indicating normal positive power
(Im-port of energy from the public grid). If the inverter or any other power
source is not producing power and some min-imal power is being used, the LEDs
should be flashing green. This is normal, when the inverter is in its 5-minute
startup cycle.
No Power
Any phase with a solid green LED indicates no power, but line voltage is
present.
No Voltage
Any phase LED that off indicates no voltage on that phase.
Generating Power
Red flashing indicates negative power for that phase. This is normal behavior
if more power is produced (by the inverter or any other power source) than
consumed (Export of energy to the public grid). If no power is produced at
all, this might indicate either reversed CT’s, swapped CT wires or CT’s are
not matched with the correct line voltage phase.
Overvoltage Warning
The following indicates that the line voltage is too high for this model.
Disconnect power immediately! Check the line voltages and the meter ratings
(in the white box on the label).
Meter Not Operating
If none of the LEDs are illuminated, check that the correct line voltages are
applied to the meter. If the voltages are correct, call customer service for
assistance.
Error
If the meter experiences an internal error, all LEDs will light up red for 3
or more seconds. If you see this happen repeatedly, call customer service for
assistance.
Modbus Communication LEDs
Near the upper left corner, there is a diagnostic Com (communication) LED that
can indicate the following:
- A short green flash indicates a valid packet addressed to this device.
- Short yellow flashes or rapid flashing indicate valid packets addressed to different devices.
- A one-second red flash indicates an invalid packet: bad baud rate, bad CRC, noise, bad parity, etc.
- Rapid red/yellow flashing indicates a possible address conflict (two devices with the same DIP switch address).
- Solid red indicates the address is set to zero: an invalid choice.
