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 it fails, please contact Enphase customer service to obtain an RMA (return
merchandise authorisation) number and start the replacement process.

Status LED Indications and Error Reporting

Startup LED Operation:

The Status LED of each microinverter will blink green six times to indicate normal start-up operation
approximately two minutes 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. LED states are:
a. Flashing Green: AC grid valid and communicating with Envoy
b. Flashing Orange: AC grid valid but not able to communicate with Envoy
c. Flashing Red: Not producing power. AC grid invalid (Voltage or Frequency). This may happen
when the microinverters have not yet been configured with a Grid Profile.
d. Solid Red plus flashing Green: DC input earth resistance fault active, AC grid valid and
communicating with Envoy
e. Solid Red plus flashing Orange: DC input earth resistance fault active, AC grid valid but not able
to communicate with Envoy
f. Solid Red: DC input earth resistance fault active and the AC grid is invalid. This may happen when
the microinverters have not yet been configured with a Grid Profile.

Reported Faults:

All faults are reported to the Envoy. Refer to the Envoy Installation and Operation Manual for
troubleshooting procedures.
