Hello everyone, I am new to this amazing forum and just want to quickly introduce myself and my project.
My name is Christof and I am located in Vancouver B.C Canada. For the last 2-3 years I have completely rebuilt my storm-damaged 36' Sailboat and removed everything that was bolted on including the whole Diesel system. After exploring many options on propulsion we have decided to go electric.
And that's why I am here.
I am looking for some guidance and help to finalize my onboard electronic specifically the 48volt side of it, i have roughly sketched out (attached) what the system is going to look like and all the components in the drawings are on hand. The 20kw Electric propulsion system is made by Electric Yachts and is very straightforward, they have provided all the info and components to make the propulsion work.
The big question marks are wire gauge sizing as well as sizing the breakers and integration of a 12-volt house battery bank past the DC/DC converter.
We have 12x 100ah Battle Born Batteries which are paired in 3x groups to make 300ah @ 48volt. 4x Batteries are wired in series connected with 4/0 battery cables to make 48-volt and I am wondering if I can use 2/0 to parallel the 3 battery banks. How big does every Pre-Battery fuse size need to be i am assuming 100amp?
Is there an easy way to calculate breaker sizes and cable gauges?
Thank you in advance for any sort of info that comes my way I really appreciate it and I am looking forward to an amazing discussion around this topic.
I am very open to alternative solutions and ideas to improve the system.
If you are further interested in the major refit project you can DM me and I am happy to share the process.
