I know very little about inverters.
Got one in a motorhome (not mine) it's fed through a fusebox and there is a changeover switch so that the inverter can't feed back into the supply if the van is hooked up.
There isn't an earth from the inverter.
Readings as follow
L-N 230v
L-E 0v
N-E 0V
Continuity
L-E open circuit
L-N open circuit
E to inverter ground stud 0 ohms
It states in the instructions that it isn't suitable to be installed as it has been, fair enough. No mention in the instructions of this ground stud on the inverter, it isn't even shown on the diagram in the instructions. It's a chinese beaut.
Question is, to fit an inverter to feed multiple sockets via a fusebox with an RCD does it have to be able to tolerate having its neutral and earth (CPC) connected at the plug feeding the supply from the inverter, as would be in a TN-C-S supply from the grid?
There are various inverters from the pro ones that let you select whether or not the inverter shorts out the neutral-earth connection itself or some that will tolerate having the neutral and earth connection shorted at the plug at the inverter and others that will go bang if you do.
There are also plenty of people saying you don't need the CPC and others saying it's dangerous without it
