NOTICE
•
N and PE wiring via ON-GRID and BACK-UP ports of the inverter are different based on
the regulation requirements of different regions. Refer to the specific requirements of local
regulations.
• The inverter has a built-in meter that can be directly connected to the CT for use.
• When the connection length between CT and inverter exceeds 20m, the accuracy will decrease.
If there are high accuracy requirements, you can connect an external smart meter.
The N and PE cables of the BACK-UP load end are connected together for wiring in the distribution
box.
This wiring method is suitable for regions such as Australia and New Zealand.
