6A is not all that limiting. Chirk marina gave us 6A at the socket. Yes a 2kW kettle draws 8A + at start up, but this is why we have a gas kettle.

We are not planning on getting an electric kettle, so the 6A is not a problem.

Have you any 13A sockets supplied by the shoreline alone? 6A is a bit limiting, especially if you wanted to plug in a kettle.

we will be out on the network soon, so we will be on Battery, Photovoltaic, and Alternator.

That is a fair point. But since the fridge draws 10A on 12V it is either going to be replaced, or be put back on gas soon.

Normally it’s not holding anything we need to worry too much about.

Sounds like the marina systen is a bit Carp!

But if you are not there to switch it over your fridge will defrost.

I did think about the use of a relay, but I don’t really want the risk of switching on load, so a change over switch means that you would have to think about what large loads are connected on switch over.

Also here at Crick marina we have three shore supply sockets between ~12 boats, so we get un-plugged quite often, I don’t really want to leave a large load on 230V and find that when we get back we have no battery due to the inverter having kicked in on it.

Why use the switch? Would it not be better to utilise a relay operated from the positive input from the shore line (this could be a simple voltage sensor) This would illiminate the need for human input. Both inverters could then be isolated. All you would have to do is plug in the shore line the relay would be energised shore line power would be applied to the internal mains system and the inverters would be isolated.
