Safety Warning
WARNING! Incorrect operation and incorrectly performed work can cause serious personal injury or material damage. The Fronius Smart Meter may only be installed and commissioned by trained personnel and only within the scope of the technical regulations. Before working with the device, read and understand all enclosed, printed, and online documents. This document does not describe all possible system configurations.
Installation Steps
Step 1: Switch Off the Circuit Breaker
Ensure the circuit breaker connected to the system is in the OFF position [power-off symbol].
Step 2: Mount the Smart Meter
Install the Fronius Smart Meter in the designated location, typically within a switch cabinet.
Step 3: Connect the Auxiliary Power Supply
Connect the power supply (100-240 V AC/DC ±10%) to the appropriate terminals (L/N/+/- or N/L/-/+).
Step 4: Connect Wiring
Connect the Smart Meter according to your system configuration. The diagrams illustrate various setups:
- 4a: 1 Phase, 2 Wires - CT: Single-phase connection using a Current Transformer (CT).

- 4c: 2 Phases, 3 Wires - CT: Two-phase connection using a CT.
- 4d: 2 Phases, 3 Wires - VT/CT: Two-phase connection using VT and CT.
- 4e: 3 Phases, 3 Wires - CT: Three-phase connection using a CT.
- 4f: 3 Phases, 3 Wires - VT/CT: Three-phase connection using VT and CT.
- 4g: 3 Phases, 4 Wires - ARON CT: Three-phase connection with neutral using an ARON CT.
- 4h: 3 Phases, 4 Wires - CT: Three-phase connection with neutral using a CT.
- 4i: 3 Phases, 4 Wires - VT/CT: Three-phase connection with neutral using VT and CT.
Step 5: Connect Data Cables
Connect data cables (CU Wire, min CAT 5, ≥0.05 mm², torque 0.4 Nm) between the Inverter and Smart Meter Modbus interface. Use terminals D+, D-, GND for Inverter communication and M1+, M1-, GND for Smart Meter Modbus communication.
Step 6 & 7: Set Up Terminating Resistor
Set up the terminating resistor if necessary. Ensure the bypass cable is connected. Refer to the manufacturer's manual. Maximum communication cable length is 300 meters.
Step 8: Switch On the Circuit Breaker
Turn the circuit breaker to the ON position [power-on symbol].
Step 9: Navigate Settings
Use the device interface to navigate settings. Press buttons once to change pages or values, and press and hold for 2 seconds to adjust or confirm.
Step 10: Enter Settings
Input initial settings, such as voltage (L1, L2, L3) and power (kW). Default values are displayed.
Step 11: Setup Password
Set a password. The factory default is '2633'.
Step 12: Setup Transformation Ratio
Configure the transformation ratio (e.g., 400 A / 10) based on your system's current transformers.
Step 13: Setup Address
Assign a Modbus address. The factory default is '001'.
Step 14: Exit Settings
Confirm and exit the settings menu.
Step 15: Start Up the Smart Meter
The Fronius Smart Meter is ready. Use the Fronius Solar.start app for system setup and monitoring. Download from the App Store or Google Play.
