GFI Tripped
This condition occurs only with the M215, M190, D380, M210, M200, and M175 microinverters. A solid
red status LED on the microinverter indicates a ground fault (GFDI) error. The LED remains red and the
Envoy continues to report the fault until the error has cleared.
If a microinverter registers a GFI Tripped condition, you can attempt to clear this condition through the
Envoy Interface. An Envoy is required to send the clear-gfi message to clear the condition. If the
condition does not clear after you perform the following procedure, contact Enphase Energy customer
support at
support@enphaseenergy.com.
To send the clear-gfi message to a microinverter:
1. From the Administration menu, choose Device Conditions and Controls.
NOTE: Do not
check the box in the Select column.
2. Click on the serial number of the unit showing the GFI condition.
The Control Flags screen appears.
CAUTION: : Do not select the reboot and cmd-alert control flags unless recommended by
Enphase. The functions are:
 reboot - reboots the inverter
 cmd-alert - clears a condition flag for a command sent
