common neutral busbar AC OUT1 and AC OUT2

Can I use a common busbar for the neutral wire of AC OUT1 and AC OUT2? In the diagram they seem to be connected inside the multiplus 2.

I have parts of my home wiring sharing the neutral wire but I want some loads to be supported by battery and some not in case of outage.

AC IN neutral will be separate.

Thanks

In the diagram they seem to be common neutral so I personally do not find an issue to use a common neutral busbar for ac out 1 and 2 but I would have liked somebody with more multiplus experience to confirm it please.... :-)neutral.jpg

I was a little concerned that the internal AC2 contactor was a double pole switch, but given that the diagram you have found shows it is single pole only then I would be confident you would be OK.

However you still need to be careful if the household circuits are protected by RCDs, you need to ensure that the neutral currents flow through the same devices as the live currents.
