• N and PE wiring via GRID and BACKUP terminals of the inverter vary based on the regulation
requirements of different regions. Refer to the specific requirements of local regulations.
• A 63A Manual Transfer Switch (MTS) is highly recommended for switching the power supply
between the grid and the inverter in the whole home backup system.
• Installing surge protective devices (SPDs) before connecting the PV strings and before
connecting to the power grid are recommended.
• The N-PE connection should be longer than 10 m.
• RCDs (Type A) with a rated residual operating current are recommended to install, 300mA on
the AC-GRID side, and 30mA on the AC-BACKUP side, while the use of an RCD with a lower
rated residual operating current is also permitted if it is required by the specific local electrical
codes.
• For Australia and New Zealand, the N cable of GRID side and BACK-UP side must be connected
together according to the wiring rules AS/NZS_3000. Otherwise BACK-UP function may be
abnormal and risky.
• The following diagram is applicable to areas in Australia, New Zealand, etc.
The PE wiring of BACKUP
terminal is not required.
