Ah! How does it then not electrocute the poor sole holding the pins of the plug?

Same as existing hard-wired inverters really: they have anti-islanding tech that only activates the inverter after it senses stable grid waveform on the plug.

 

How it deals with 2 or more inverters all on the same circuit being islanded together, I'm not sure.

Not sure I'd want to hold the ac connection on any inverter with panels connected. I beleive the grid disconnect is via relays/contactors and I know the contacts do weld from time to time.

Don't the modern single block mcb+rcbo units do this, if not why do they have a neutral terminal.

The neutral needs to pass through an RCD/RCBO to monitor for earth leakage if there's an imbalance in current in the live and neutral. You don't have to break the neutral to do the monitoring although I think you can get double pole RCBOs in a single module width.

Quite interesting! Thanks for that.

People will just be plugging these in with near zero GAF though, I expect.

Although amended by @Nickfromwales the inverter will have a 13A type plug, to allow it plug directly into a standard wall socket.

I'll get my coat.......

Inverter is dead without mains, otherwise you kill every lines man in a power cut.
