What it means
The manual says: Electricity meter communication failure - ensure meter communications are stable and connected into the correct socket on the underside of the inverter.
Part involved: Energy meter / CT clamp communication.
Likely causes:
- Electricity meter communication failure.
Is it safe?
| Does the inverter stop? | Partly |
|---|---|
| Severity | Warning |
| Engineer needed? | Yes |
The inverter keeps running with some functions stopped.
Resetting itself: yes - clears when communication is restored.
Manual reset: no.
What you can check
- Read and note the exact code and time from the inverter display or app (screenshot).
- Check the meter's display is lit (look only).
- Note any recent electrical work near the meter/consumer unit.
- GivEnergy's customer guide allows a restart: turn off the DC (solar) and AC isolators, then restart the battery with its side button; or use the app/portal. Contact the installer if the alarm returns.
What the engineer will check
- Check meter RS485/Modbus wiring polarity and termination.
- Check CT orientation (arrow towards grid/house per manual) and seating.
- Check meter address/baud settings.
- Check export-limit setting (G99) - some inverters stop if export control is on and meter lost.
Who to ask for: PV/battery installer.
Certification: Installer or electrician for meter/CT/comms cabling; homeowner can handle Wi-Fi/router issues.
