So I'm currently in the middle of an off grid vintage travel trailer renovation and have been actively trying to learn electrical basics in my "down time." I've read William's book, have been reading forums, and absorbing what I can infer from videos and diagrams of similar setups to what I'm trying to achieve.
I'm starting to install my electrical components for my solar system and would really appreciate any advice or feedback so I'm not just entirely winging it. I have a Model S battery, all in one MPP PIP2424LV-MSD inverter, 400w of solar to start with (expanding to at least 800w), and a 50 amp inlet for shore power.
The 50 amp has two 120v leads so only one can go to the MPP. The other I was planning on running to an AC breaker box for outlets meant only for when shore is available. I came across this diagram for an article where a 30 amp breaker in a small sub panel was used for the 120v lead that feeds into the inverter.
Would it be correct to use 6 awg from the inlet to the 30amp sub panel breaker, and then 8 awg to MPP AC in? Or can I use 6 awg on an mpp?

On the AC out I am planning to run back to the main AC breaker box, as depicted in the attached diagram with two leads feeding different circuits from the same box.
The diagram shows a 50 amp main breaker coming from the inverter, so should I use 6AWG on the AC OUT to the main breaker box?
Honestly this part is really confusing to me so if anyone has any advice on a simple way for me to approach figuring this out please share!

I don't want to make this post too involved so my last things I am curious about sizing correctly are for my 12V system.
I am planning on getting a 24V>12V 100amp step down converter to feed my 100amp capacity 12v fuse block. Is that the right size or should it be higher or does it not even need to be that much? I doubt I'll use all 100amps of 12v, but I'd like the option to add on nonetheless.

I also got a victron 220amp battery protect, as well as the BMS, and other peripherals Will suggests for a Model S setup, but I'm not sure what size bolt on fuse I should use on the battery powering a 120v breaker panel and 12v fuse block. Should I stick with the recommended 175amp bolt on fuse? This MPP is 2400w so should I increase this to 200amps because of this or more because of the large step down converter?
Thanks for any help you can offer!
Yes, I realize I'm in slightly over my head experience wise. But this subject is finally making more sense to me, so hopefully I'm almost there and not just further away than I can even imagine on this... ?
I'm definitely a practice makes perfect learner so I am totally exercising caution with respect to this install.
