[QUOTE="Feenster, post: 552763, member: 37736"] The old inverter has the same set up - it has a N-E link as well. However, it has worked fine for a number of years. Perhaps the new one, since it is more powerful, is causing a greater loss down the earth. Removing the N-E link isn't difficult - I tried that already. However, I simply moved the N-E link to the fuse board, which I saw recommended on a number of sites. Same problem, RCD tripped (which isn't surprising really considering I only moved the link to a different point). Now I assumed that I had a TN-S system and it was I who was providing the earth by means of an earth rod. And as with any TN-S system the neutral of the source (i.e. the inverter) is connected with the earth at one point only and if that is in the inverter so be it. Having looked up the TT system it appears that I would need 2 earth rods. There appears to be a N-E link at the source. Does that mean using the N-E link in the inverter and connecting to one earth rod? [ATTACH type="full"]16382[/ATTACH] [/QUOTE]
