GFDI Fault

For M215-60-2LL-S22, S23, or S24, a solid red status LED when DC power has been cycled indicates
the microinverter has detected a ground fault (GFDI) error. The LED will remain red and the fault will
continue to be reported by the Envoy until the error has been cleared.
An Envoy is required to clear this condition. The condition usually clears with operator intervention unless
conditions causing the event have not been remedied or if the failure is permanent. You can attempt to
clear this fault through Enlighten or by using the Envoy interface.
If the condition does not clear after you perform the following procedure, contact Enphase Energy
customer support at support@enphaseenergy.com.

Other Faults

All other faults are reported to the Envoy. Refer to the Envoy Communications Gateway Installation and

Troubleshoot an Inoperable Microinverter

To troubleshoot an inoperable microinverter, follow the steps in the order shown.
WARNING: Always de-energize the AC branch circuit before servicing. Never disconnect
the DC connectors under load. Disconnect DC connections first, and then disconnect the
AC connections.
WARNING: The Enphase Microinverters are powered by DC power from the PV
modules. Make sure you disconnect the DC connections and reconnect DC power to
watch for the solid green about six seconds after connection to DC power and then six
short green LED blinks two minutes after connection to DC power.
1. Make sure AC breakers and disconnects are closed.
2. Check the connection to the utility grid and verify that the utility voltage is within allowable
ranges shown in "Specifications" on page 35 of this manual.
3. Verify that AC line voltages at all solar power circuit breakers at the load center and
subpanels are within the ranges shown in the following table.
4. Verify that AC line voltage at the junction box for each AC branch circuit is within the ranges
shown in the following table:
240 Volt AC, Split Phase
L1 to L2
L1, L2 to neutral
5. Using an Enphase disconnect tool, disconnect the AC cable for the microinverter in question
from the Engage Cable.
