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 authorization)
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 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 – AC grid valid and communicating with Envoy
Flashing Orange – AC grid valid but not able to communicate with Envoy
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.
Solid Red plus flashing Green – DC input earth resistance fault active,
AC grid valid and communicating with Envoy
Solid Red plus flashing Orange – DC input earth resistance fault active,
AC grid valid but not able to communicate with Envoy
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.
