GFDI Error
Other Faults
A four time red LED indicates the Microinverter has detected a
Ground Fault Detector Interrupter (GFDI) error in the PV system.
Unless the GFDI error has been cleared, the LED will remain four
times blinking.
All other faults can be reported to the website and APP.
WARNING
:
Never disconnect the DC wire connectors under load. Ensure that no
current is flowing in the DC wires prior to disconnecting. An opaque
covering may be used to cover the module prior to disconnecting the
module.
There are two possible overall areas of trouble:
A. The Microinverter itself may be having problems.
B. The Microinverter itself is working fine but the communication between microinverter
and network has problem. The items below refer to Microinverter issues, not communicat
-ion issues:
One quick way to tell whether the issue is the Microinverter or the communication problem:
1. Diagnosing from the Microinverter: A red light–either blinking or solid on the
Microinverter, or no light at all means it is definitely the Microinverter problem.
2. 0 watts, or 2 watts: Possibly a Microinverter problem
