[Electric Boats] Crosswiring batteries - or who charges who?

 

Hello everyone, I was curious about how you people out there are wiring your chargers, Batteries and house batteries against each other?

So here is my thinking:
I have the 48 Volt Battery bank for my Electric drive and a 12V Battery for house loads. The 12V are charged off a 48 Volt to 12Volt converter.
The n there is a solar Panel producing 12 Volt via a MPPT Controller, which is linked to a 12V to 48 Volt converter to charge the 48Volt Bank.
Also there is a Bettery charger for the 48 Volt in case shore power is hooked up. I don't think an extra 12 Volt charger makes sense (or am I wrong there?)

And then of course there could be a Generator as well as backup: Do you just hook that up to shore power and charge that way or hook it up seperately somewhere else?

I'm grateful for any advice people can give me on how to wire it all together!
Thank you all already!
