4.4.6 Earth Fault Alarm
In compliance with the section 13.9 of IEC62109-2, the DT/SDT series inverter is equipped with an
earth fault alarm. When earth fault occurs, the fault indicator at the front LED screen will light up.
On inverters with Wi-Fi communication, the system sends an email with the fault notification to
the customer. For inverters without Wi-Fi, the buzzer of the inverter will keep ringing for one
minute and ring again after half an hour until the fault is resolved. (This function is only available
in Australia and New Zealand).

SEMS Portal is an online monitoring system. After completing the installation of
communication connection, you can access www.semsportal.com or download
the App by scanning the QR code
to monitor your PV plant and device.
Please contact the after-sales for more operation of SEMS Protal.
