Eh? Anyway, I'm finding it really difficult to follow what you actually want. So I'm going to read between the lines.
Brutally honest, I don't think you know what you are getting into, from the language and questions I'm not convinced you have the skill set. I don't think you appreciate how much it will cost you to refit a boat. Even your solar install will cost you much more that you think. You haven't factored cables, connectors, crimps, ties, labels, conduit, clamps, switches, breakers, isolators, fuses, buzz bars, tools, more tools etc etc. You probably want to factor in a second set of batteries for when you destroy the first set through mis-charging them...
