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.
Solid Red:
DC resistance low fault. Troubleshoot as described in the following section.
DC Resistance Low Fault:
A solid red status LED when DC power has been cycled indicates the microinverter has detected a DC
Resistance Low event. 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.
Follow the instructions in the Envoy Communications Gateway Installation and Operation Manual at
http://www.enphase.com/support to clear this condition. Or, for assistance, contact Enphase
customer support at [email protected].
Other Faults:
All other faults are reported to the Envoy. Refer to the Envoy Communications Gateway Installation
and Operation Manual at http://www.enphase.com/support for troubleshooting procedures.
