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...

I am still confused by this. From my diagram above, the power from the inverter goes to the fuse board. It goes through the RCD and then to the individual MCBs for each of the ring circuits. Is the RCD not between the inverter and the circuits? So if the mower cuts the wire, the RCD trips and...

I have tried another RCD - unfortunately the same result, it 'trips'.

(The circuit that I attached on Monday (there should be a '+' and '-' between the battery and inverter not 'live' and 'neutral') doesn't show that there is a neutral-ground bond inside the inverter itself. It can be manually removed.) I was off the opinion that I had a TNS system. Perhaps I am...

Each of the ring circuits have 2.5 mm cables. However, there is very little load on any of the circuits. Because we are off grid the electric kettle is probably the most powerful appliance we have. Most of the circuits just have table lamps, etc.

Chewbacca, can you explain this some more to me please? On the 'house side' of the RCD, if the RCD goes am I protected? Is it between the Inverter and RCD that the problem is, where 'the shutdown time of the inverter can basically kill you'?

Thanks for that. So, just to be clear, after the main switch on the fuse board, remove the RCD and put in 7 RCBOs, one for each ring circuit? Should I do any thing with the circuits for the lights (not shown below). At the moment each circuit is protected by a MCB but no RCD.

Looking for a bit of help. I bought a PIP4048 from MPPSolar many years ago and bought a new PIP5048 just recently. I live off-grid and have a generator for back up. Recently I replaced the PIP4048 with the new PIP5048. The PIP5048 started up fine. However, when I started to turn on the MCBs on...
