Victron Phoenix 12 80 2000 swaps line and neutral when inverting.
Marine installation, has been working for many years with occasional shorepower RCD trip.
The outlet sockets on the boat are switched on by a small MCB on the board. The MCB is solely and directly supplied from the Multi‘s output Line wire, N combines to all other Ns.
The Multis input is correctly wired to shorepower.
With the socket MCB switched off, all other MCBs lines are life when shorepower is connected.
As soon as the socket MCB is switched on the external shorepower RCD trips.
If shore power is internally switched off at double isolator. I can switch the socket MCB on and consumers supplied by these socket outlets will work.
However, I can now no longer detect a life signal at the supply line point of the outlet socket MCB but instead on the combined neutral point on the board!
This is of course the same with every socket, a life signal on all neutrals.
What is happening here?
