Help Find My Mistakes! - Electrical Diagram

Hi everyone!

This will be my first build. I made an electrical diagram and I am hoping to get feedback as I am very new to all this.
Just a few notes about the diagram:

  • The diagram is just the DC side for now
  • I will be adding additional 12v devices to the diagram (Fridge, possibly an Air Condition, etc)
  • I believe the wire size is a little overkill for what I am currently planning but I would like to have the ability to upgrade easily in the future
  • Does anyone see anything that would cause any problems? I want to try to avoid anything that can cause a short or other electrical problems.

Any and all feedback welcome!

Thank you all!

200w =16.67a @ 12vdc
50a @ 12vdc = 600w

I only have1 200ah batter for our minivan with 2000watt inverter, which I don’t see your using, I added small on/off switches to things on my fuse box like the LED lights, Fan
