For Australia and New Zealand installation site, the neutral cable of grid side and backup side must be connected together, otherwise backup output function will not work.
Residual Current Protection
The inverter is equipped with an all-pole sensitive residual current monitoring unit (RCMU) with an integrated differential current sensor which fulfills the requirement of DIN VDE0100-712(IEC60364-7-712:2002).
Therefore, an external residual current device (RCD) is not required. If an external RCD needs to be installed because of local regulations, a RCD type A or type B can be installed as an additional safety measure.
The all-pole sensitive residual current monitoring unit (RCMU) detects alternating and direct differential currents. The integrated differential current sensor detects the current difference between the neutral conductor and the line conductor. If the current difference increases suddenly, the inverter will disconnect from the grid. The function of the all-pole sensitive residual current monitoring unit (RCMU) has been tested according to IEC62109-2.

Notice of installing an external residual current device (RCD) for installa- tion of Australia and New Zealand
