Updated with multiple chargers. Hopefully this picture is more clear. It automatically resized the first one on upload.
Regarding the specifics on each component, that is were I need recommendations. I am first trying to see if the general layout makes sense so I can then start to spec the individual components based on the load requirements shown.
Lets assume frequency of use will be worst case (everything on all the time) and then I can work back from there. AC would be powered by shore power or generator. Not expecting to power that for long / if at all from the batteries.
