Design for 48v house system

[FloaterBoater]

I'm hoping for some review / commentary on my design for the house system on my boat.

Parameters

• The boat is a fully residential dutch barge, lived on 365 days/year.
• All electric kitchen with 240v domestic appliances (induction cooktop, oven, separate fridge, freezer, combo washer dryer)
• Loads can reach up to 30-32A
• Generator, Isolation transformer, sterling battery charger and 4X12v batteries are existing equipment
• Installation will be in a large dry engine room
• Daf 575 engine with dual 24v alternators
• Images in diagrams not exact equipment matches. List of component on left of diagram
• Cerbo GX unit not shown
• Primary requirement is to reduce reliance on shore power, and be able to cruse occasionally without compromise to liveability (it's my home, i don't want to feel like I'm camping).
• Not all fuses marked, just the primary ones. Cable size not marked.
• For now, no alternator charging of main 48v bank. In future looking to add a 48v alternator with wakespeed 500 controller and remove house 24v alternator
• Typical usage summer 8-10kWh. Winter 6-8kWh (water heating by diesel boiler in winter)

Thanks for any thoughts.

Made it with Google drawings. It's not really the best for this, but it's free
