Note:
1. Meter is not a standard accessory for grid-tied inverter. You may contact sales if meter is in need.
2. The compatible DRM commands are DRM0, DRM5, DRM6, DRM7, DRM8.
3. You may refer to guidance in Smart Meter User Manual if meter is required.
4. DRED option is available only for Australia and New Zealand.
5. To implement export power limitation, meter is required to install in the system. The function
should be enabled and threshold value set on local LCD or SolarGo by following the steps at
section 5.2 User Interface and System Operation.
4.4.6 Earth Fault Alarm
In compliance with the section 13.9 of IEC62109-2, the SDT G2 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 inverter with Wi-Fi communication, the system sends an email with the fault notification to the
customer. For inverter 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).
4.4.7 SEMS Portal
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.
Step 4:
Put the cable through the plate.
