SINGLE PHASE HI 3.6/5kW | Installer Manual26
An Earth Cable shall be connected to the earth plate on the grid size in order to prevent electric shock if the
original protective conductor fails.
All neutrals can be linked together to maintain the neutral bond. When a Neural Earth bond is required for
an ‘O-grid’ operation, then it has to be removed on ‘Grid-Tied’ operation.
If an Earth Bond is required between neutral and earth and your system is a hybrid system, then you can
have a permanent earth wire since this can cause faults with an RCD before the inverter.
