2. Power up the inverter using only PV
3. Set inverter country code as 02(Australia) in
Enter Settings > Set Country Code > 02
4. Enable DRMs function in
Enter Setting > Logic Interface > Enable
5. Only DRM0, DRM5, DRM6, DRM7, DRM8 has been implemented to
work with corresponding relay enclosure. The priority for operation is
DRM0>DRM5>DRM6>DRM7>DRM8.
4.7. Safety check
Photovoltaic array
Before the inverter operation, need to be examined for the photovoltaic array,
Check Open circuit voltage of each PV string against the expected electrical
design.
-Ensure Open circuit voltage of the each PV array accord with the requirements;
-Ensure that the positive and negative polarity is correct.
