Generator and Inverter

[mikenash]

I'm interested in the grounding/earthing question too

I have solar + inverter.  From time to time I use a Chinese Honda-clone petrol generator as well

The "wiring" in my shed is carefully done but there is no earth because there is no switchboard - rather there's an extension flex with a 10A plug which either goes into the inverter or the generator.  At the other end of the extension flex there's an RCD

I have been told both that I should and should not run an earth stake at the generator; also that I "could if you wanted" run an earth at the inverter

To my way of thinking - if there's fault current - the RCD will trip.  I don't see what contribution an earth stake will make unless there is a switchboard and a path to neutral/earth so that current can flow to blow a fuse or pop an overload

But I'd be interested in the thoughts of better-qualified folks

Thanks, Mike
