M215 Installation and Operation

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.
