Re: Inverter replacement
We will currently be using the inverter/charger as an inverter only and keep the balance of systems and chargers as they are. We will not be connecting an AC source to the invert/charger, yet. I looked for the Amel schematics of the inverter/shore power/generator selector switch and found it in the original Amel schematics supplied with the Boat.
It appears that there is a selector switch between the shore power and the generator for the AC panel, except the 220V and the microwave breakers. The power for these goes through another selector switch that selects the power source from the selector output of the generator/shore power switch and the inverter. If there is power coming in from either the generator or shore power, then the inverter is disconnected.

1.Normally inverter chargers all have sleep modes. There will be a sensitivity setting that looks for a load. Some electronics demand so little power that the big inverter can not see it. This searching will use a little power.
2. If there is an AC source applied to the inverter charger then it will automatically bypass inverter mode and become a charger and all AC demands that would otherwise be met by the inverter are now met by the AC supply.
So in practice if the generator is running or shore power, so long as the 100A charger switch is on then the outlets fed by the inverter will be fed directly by the AC source.
If however the 100A switch is off then the inverter will supply those outlets.
So with Lithium, if you are happy there is enough capacity you could just use the big inverter to supply the whole AC part of the boat simply using the inverters internal change over switch.
I know some people think that is not belt and braces enough…but …..not sure.
