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 Siemens Microinverter; it contains no user-
serviceable parts. If it fails, please contact Siemens customer service to obtain an RMA
number and start the replacement process.
Status LED Indications and Error Reporting
Startup LED Operation:
One minute after DC power is first applied to the microinverter, six short green blinks
indicate a successful microinverter startup sequence.
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 mechanics mirror to view indicator lights on the undersides of the microinverters:
Flashing Green – Producing power and communicating with Envoy
Flashing Orange – Producing power and not communicating with Envoy
Flashing Red – Not producing power
Solid Red – GFDI Fault
Ground Fault Detection Indicator (GFDI) Fault:
A solid red status LED when DC power has been cycled indicates the microinverter has
detected a ground fault 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.
Follow the instructions in the Envoy Communications Gateway Installation and Operation
Manual to clear this condition. Or, for assistance, contact Siemens customer support at 1-
800-241-4453 or at info.us@siemens.com.
Other Faults:
All other faults are reported to the Envoy. Refer to the Envoy Installation and Operation
Manual for troubleshooting procedures.
