Troubleshooting

Adhere to all the safety measures described throughout this manual. Qualified personnel can use the
following troubleshooting steps if the PV system does not operate correctly.
WARNING: Do not attempt to repair the Enphase Microinverter; it contains no user-
serviceable parts. If the microinverter fails, contact Enphase customer service to obtain
an RMA (return merchandise authorization) number and start the replacement process.

Status LED Indications and Error Reporting

Startup LED Operation:

The Status LED of each microinverter blinks green six times to indicate normal
start-up operation approximately one minute after DC power is applied.
Six short red blinks after DC power is first applied to the microinverter indicate a
failure during microinverter startup.

Post-Startup LED Indications

Use a handheld mirror to view indicator lights on the undersides of the microinverters:

Flashing Green: Indicates normal operation. The microinverter is receiving messages from
the Envoy and senses that the utility grid is within voltage/frequency specifications.

Flashing Orange: Indicates that the microinverter is not receiving messages from the Envoy,
but is otherwise operating normally. The microinverter senses that the utility grid is within
voltage/frequency specifications.

Flashing Red: Indicates that the microinverter is not operating normally. The microinverter
does not sense that the utility grid is within voltage/frequency specifications. The
microinverter cannot produce power until this is resolved. See "Troubleshoot an Inoperable
Microinverter" on page 22.

Solid Red: GFDI fault. Troubleshoot as described in the following section.

GFDI Fault

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.
The condition should clear with operator intervention unless conditions causing the event have not been
remedied or if the failure is permanent.
