Australia Grid Code N-bypass

What does N-bypass in the grid code selection for Australia mean?

Under what circumstances would you choose between the two options? ('no N-bypass' & 'with N-bypass')

Thanks,
Peter.

Thanks Rob.

Any thoughts on the second question about when you would use one or the other?

Hi

OK to do with the ground neutral bond test that the Multiplus does to check and see that there is neutral path.

Depends on your wiring of the inverter to the house loads etc.

Rob,

So in a situation where a Victron Inverter AC-In is connected down stream of the main switchboard and its AC-Out supplies ALL house loads, should 'No N-bypass' be selected?

Answering my own question above as to what A, B and C.

Setpoints are now defined by region of installation, as per the following categories:

  • Australia A: For large interconnected power systems, e.g. all Australian networks other than those specified below
  • Australia B: For small interconnected power systems, e.g. Western Power
  • Australia C: For isolated or remote power systems e.g. Horizon Power and TasNetworks
  • New Zealand: All systems in New Zealand
