gfi-tripped on an Enphase Energy Enphase IQ8 microinverters: Ground fault (GFDI) detected by older M215/M190/D380/M210/M200/M175 microinverters; solid red LED
Short answer
On an Enphase Energy inverter, gfi-tripped means: Ground fault (GFDI) detected by older M215/M190/D380/M210/M200/M175 microinverters; solid red LED. The inverter keeps running with some functions stopped. An engineer is needed to fix the cause.

What it means
The manual says: Ground fault (GFDI) detected by older M215/M190/D380/M210/M200/M175 microinverters; solid red LED.
Part involved: ground fault detection.
When it shows: Ground fault (GFDI) detected by older M215/M190/D380/M210/M200/M175 microinverters; solid red LED.
Likely causes:
- Ground fault current on DC side (e.g. damaged module/cable).
Is it safe?
| Does the inverter stop? | Partly |
|---|---|
| Severity | Fault — needs a manual reset once the cause is fixed |
| Engineer needed? | Yes |
The inverter keeps running with some functions stopped.
Resetting itself: no.
Manual reset: Installer sends clear-gfi command via the Envoy.
What you can check
- Open the Enphase App (or Enlighten) and note the event name, affected microinverter serial number(s) and date/time for your installer.
- Contact your installer.
What the engineer will check
- Send clear-gfi via Envoy/Installer Platform; investigate module/wiring if it recurs.
Who to ask for: Enphase-certified installer / MCS PV installer.
Certification: Qualified electrician (BS 7671; MCS-certified PV installer for work on the PV array/DC side).
