I have a Broom 35' with Twin Volvo TMD40A (130Hp each) diesel engines and the boat is in need of a rewire. I have started to map out both the existing, and some of the new features (smart chargers, solar, etc.) that I would like to add to improve the boat. It has both 24V and 12V on board and is wired mostly typical of the period in early 80's. My question is mainly around advice on possible wiring arrangements for starting and charging of the battery banks underway. The power audit I just completed suggests I would need about 330Ah of 12V, and 125Ah of 24V if we are moored for 2 days without power. My start batteries need to be replaced, and the 450Ah 12V bank shown is a plan for early next year when I complete the refit. I omitted on the diagram that I have a dedicated 12V charger that is spare and I will probably fit that to the start batteries so they are fully ready for cranking when I am on shore power.
I would be very happy to hear suggestions for VSR/ACR's to help manage the starting of both engines, and the charging of the batteries. In particular advice on more current practices to reduce complexity and better utilize the two 12V (60A each I believe) alternators while underway. Also glad to hear any advice on protection for devices such as the Pro-Chargers or solar system when cranking, charging from alternators.
Let me know if I need to add more info that I may have missed.
