How do I install the Fronius Smart Meter at the feed-in point?

[DelColeman]

Installing a Fronius Smart Meter at the feed-in point correctly ensures accurate energy monitoring for your solar power system. Here's a step-by-step guide:

1. Mounting:

   • The Fronius Smart Meter features mounting holes spaced 5.4 inches apart. Detach the terminal covers to access these holes.
   • Use the self-tapping sheet metal screws provided to mount the meter securely. Avoid over-tightening the screws to prevent damage to the casing.

2. Circuit Protection:

   • The Fronius Smart Meter is classified as permanently connected equipment, requiring a disconnect mechanism (circuit breaker, switch, or disconnect) and overcurrent protection (fuse or circuit breaker).
   • The switch, disconnect, or circuit breaker should be easily accessible, positioned near the Smart Meter.
   • Use circuit breakers or fuses rated for 20 amps or less to protect the mains terminals, labeled L1, L2, and L3.

3. Line Wiring:

   • Always disconnect the power supply before connecting the line voltage inputs to the Fronius Smart Meter.
   • Use 16 to 12 AWG stranded wire for line voltage connections.
   • Connect each wire to its corresponding phase, ensuring proper grounding and neutral connections where applicable.

4. Current Transformer (CT) Installation:

   • Place the Current Transformers (CTs) around the line conductors, making sure they face the correct direction.
   • Connect the white and black CT wires to the Fronius Smart Meter terminals labeled CT L1, CT L2, and CT L3.

5. Data Communication Cable Connection to Inverters:

   • Depending on your specific inverter model (such as a Fronius SnapINverter or Fronius GEN24), connect the data communication ports of the Fronius Smart Meter to your inverter's monitoring system.

6. Commissioning:

   • After completing the physical installation, turn on the power to the Smart Meter.
   • Verify correct operation by checking the meter's LEDs and power status indicators.
   • Access your Fronius System monitoring software to ensure compatibility between your inverter and the Smart Meter. This confirms that data is being accurately recorded and transmitted. By following these steps, you can successfully install your Fronius Smart Meter for optimal performance and accurate energy monitoring.
