INV_GFCI_FAULT on a GivEnergy Cloud portal / GivEnergy app and Wi-Fi dongle: GFCI (earth leakage) fault - make sure that there is no DC voltage to earth
Short answer
On a GivEnergy inverter, INV_GFCI_FAULT means: GFCI (earth leakage) fault - make sure that there is no DC voltage to earth. The inverter stops until the fault clears or is reset. An engineer is needed to fix the cause.

What it means
The manual says: GFCI (earth leakage) fault - make sure that there is no DC voltage to earth.
Part involved: Residual current / ground fault monitoring (RCMU).
Likely causes:
- GFCI (earth leakage) fault.
Is it safe?
Switch the inverter off at its isolator if the code comes back.
| Does the inverter stop? | Yes |
|---|---|
| Severity | Fault — clears by itself when the condition goes |
| Engineer needed? | Yes |
The inverter stops until the fault clears or is reset.
Resetting itself: may retry; persistent or repeated trips need investigation.
Manual reset: sometimes.
What you can check
- Read and note the exact code and time from the inverter display or app (screenshot).
- Check the solar/battery AC isolator and the consumer-unit breaker/RCD are ON (do not reset a breaker that trips again immediately).
- Do not touch DC cabling or open the inverter; manufacturer says only a qualified technician should handle this.
- 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
- Isolate AC and DC, wait for capacitors to discharge (5 min SolarEdge).
- Reconnect strings one at a time to find the faulty string.
- Insulation-resistance test.
- Check AC neutral/earth connections.
Who to ask for: PV installer.
Certification: Electrician competent in grid-connected PV (BS 7671 Section 712; IET Code of Practice for Grid-connected Solar PV), ideally the original MCS-certified PV installer; brand-approved/trained installer to keep manufacturer warranty.
