6�1 System Wiring Diagram
• 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.
• There are built-in relays inside of the inverter's ON-GRID and BACK-UP AC ports. When the
inverter is in the off-grid mode, the built-in ON-GRID relay is open; while when the inverter is in
grid-tied mode, it is closed.
• When the inverter is powered on, the BACK-UP AC port is charged. Power off the inverter first if
maintenance is required for the loads connected with BACK-UP ports. Otherwise, it may cause
electric shock.
N and PE cables are connected together in the Main Panel for wiring�
• To maintain neutral integrity, the neutral cable of ON-GRID side and BACK-UP side must be
connected together, otherwise BACK-UP function will not work.
• The following diagram is applicable to areas in Australia, New Zealand, etc.
