Designing TT electrical system

I am looking for feedback on this schematic of my proposed TT electrical system. Its work in progress, but let me know what you think.

I have begun the process of replacing the core electrical system on my 2019 Jay Flight TT 248 RBSW. I decided to go with Victron components because I have used them in the past on a large boat. This is my first install (as the boat came installed). Once I get the schematic correct, my next step is to size the wire and fuses.

I will continue to post updates as I move along through the project.

My first response... $,$$$,$$$.00 lots of capacity.

I don't know what size/model you are using in the + and - Battery Buss, We always suggest putting the high current leads on the same terminal and let the branch loads go on the other terminals. (example - Neg from the current shunt to a terminal that is shared with the chassis ground lead and shared with the Inverter neg)

Maybe I'm being too detailed oriented.

According to the diagram, the inverter/charger seems to have the wiring off. The general concept is correct but the locations of where the input/output appears to be wrong.

I am currently building a Victron 12v3000 system and just want to see if I'm just letting my OCD get the best of me.

Yes ChevyMan your OCD is in overdrive. In my line of work (computer systems) schematic drawings are a generalized representation of the layout and big-level connections between various components. They are never intended to be a detailed set of instructions. My wiring doesn’t make 90 degree bends either in real life. Lol.

Also, complaining about a post that is 18 months old seems a little strange. But I wish smooth sailing on your project and that all goes well!! Cheers.

Snow dog; Can you post an update on the status of your design and did you implement it?

There has been a number of posts on these Victron's recently and should spend some time to understand them.

Thanks for clearing that up,

I understand the post is an older one. Once it's out there it always can be viewed it which I did when I was doing my research within the Forum. It was just to see if anyone's used the victron inverter component, never intended to be critical of a diagram.

Many miles, be safe.

I implemented the system almost exactly like the diagram. It has worked great for 2 years now. I did have an in-line fuse with a mechanical issue that caused it to arc and melt. I replaced it with a resettable breaker unit. I added a second smaller solar controller for a 200w suitcase unit for camping in shady locations. Other than those changes everything is as diagramed. No regrets!
