The Fronius Smart Meter is a bidirectional electricity meter for optimizing self-consumption 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.

The Fronius Smart Meter is a bidirectional electricity meter for optimizing self-consumption 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.

The Fronius Smart Meter can be installed at two possible locations in the system, at the feed-in point and at the consumption point.

Positioning at the feed-in point
The positioning of the Fronius Smart Meter at the feed-in point.

Positioning at the consumption point
The positioning of the Fronius Smart Meter at the consumption point.

The Fronius Smart meter has two mounting holes spaced 5.375 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.

The Fronius Smart Meter is considered “permanently connected equipment“ and requires a disconnect means (circuit breaker, switch or disconnect) and overcurrent protection (fuse or circuit breaker).

The Fronius Smart Meter only draws 10-30 mA, so the rating of any switches, disconnects, 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.
• Use 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 overcurrent protection device must interrupt both neutral and ungrounded conductors simultaneously.
• The circuit protection / disconnect system must meet IEC 60947-1 and IEC 60947-3, as well as all national and local electrical codes.

• Always turn off power before connecting the line voltage inputs to the Fronius 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 models 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 disconnect the power switch immediately!

Single-Phase Three-Wire (Mid-Point Neutral) (only 240 V-3)

Two-Phase (Australia) (only 480 V-3)

Single-Phase Two-Wire without Neutral (only 240 V-3 and 480 V-3)

Single-Phase Two-Wire with Neutral (only 240 V-3)

Three-Phase Four-Wire Wye

Three-Phase Three-Wire Delta without Neutral (only 240 V-3 and 480 V-3)

Three-Phase Four-Wire Stinger

Three-Phase Two-Wire Corner Grounded Delta (only 240 V-3 and 480 V-3)

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, especially 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.

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.

3Connect - to GND.

• Use a CAT5 type cable or higher.
• For data lines belonging together (D+, D- and M1+, M1-) use a twisted pair of cables.
• If the output cables are close to the mains wiring, use wires or cables rated at 300 V to 600 V (never less than the operating voltage).
• Use double insulated or sheathed output cables when near bare conductors.
• Use shielded twisted pair cables to avoid interference.
• The outputs of the Fronius Smart Meter are galvanically isolated from dangerous voltages.

The Fronius Smart Meter must be connected to the Fronius Datamanager. If only one Fronius Smart Meter is installed, the Modbus Address is 1.

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 (Import of energy from public grid).
If the inverter or any other power source is not producing power and some minimal 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 is off indicates no voltage on that phase.

Generating Power
Red flashing indicates negative power for that phase. This is a 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.

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.

The Fronius Smart Meter has an optional neutral connection that may be used for measuring wye circuits. In the absence of neutral, voltages are measured with respect to ground. The Fronius Smart Meter uses the phase L1 (øA) and phase L2 (øB) connections for power.

Over-Voltage Limit: 125% of nominal Vac. Extended over-voltage operation can damage the Fronius Smart Meter and void the warranty.
Over-Current Limit: 120% of rated current. Exceeding 120% of rated current will not harm the Fronius Smart Meter but the current and power will not be measured accurately.
Maximum Surge: 4 kV according to EN 61000-4-5
Power Consumption: The following table shows maximum volt-amperes, the power supply ranges, typical power consumption, and typical power factors with all three phases powered at nominal line voltages. The power supply consumes most of the total power, while the measurement circuitry draws 1-10% of the total (6-96 milliwatts per phase, depending on the model). Due to the design of the power supply, the Fronius Smart Meter draws slightly more power at 50 Hz.

*) The Rated VA is the maximum at 115% of nominal Vac at 50 Hz. This is the same as the value that appears on the front label of the Fronius Smart Meter.

Maximum Power Supply Voltage Range: -20% to +15% of nominal (see table above). For the 3D-240 service, this is -20% of 208 Vac (166 Vac) to +15% of 240 Vac (276 Vac).
Operating Frequencies: 50 / 60 Hz
Measurement Category: CAT III
Measurement category III is for measurements performed in the building installation. Examples are measurements on distribution boards, circuit breakers, wiring, including cables, bus bars, junction boxes, switches, socket outlets in the fixed installation, and equipment for industrial use and some other equipment, for example, stationary motors with permanent connection to the fixed installation.

The line voltage measurement terminals on the meter are rated for the following CAT III voltages (these ratings appear on the front label):
