10. TROUBLE SHOOTING
Earth Fault Alarm
This inverter complies with IEC 62109-2 clause 13.9 for earth fault alarm
monitoring. If an Earth Fault Alarm occurs, the error code 6 will be
displayed on the LCD. Red LED indicator will also light up.
If an external indication of earth fault alarm is required, please connect PV
System to inverter monitoring app/portal. The monitoring platform will
send email notification in the event of an Earth Fault. Please refer to Sector
6.1 and the Wi-Fi stick guide on how to setup your inverter communication
function.
Full Error Code and Corrective Measures
When the PV system does not operate normally, we recommend the
following solutions for quick troubleshooting. If an error occurs, the Error
code will be displayed on the inverter’s screen or on the monitoring App/
Web, the red LED will light up. The corresponding corrective measures are
as follows:
