Please Review Wiring Diagram

I appreciate any help looking at this and letting me know what i need to add, remove, or just won't work. Specifically not sure where things like shunts or switches go.

EDITED BECAUSE I APPARENTLY CANNOT READ A SCHEMATIC TODAY

I totally misread the series/parallel bits and got 'em backwards. Looks like you've got things in the battery bank tied up right.

whoops!

Why two separate solar arrays with two MPPT chargers?

I was told over on spt forum that it was cheaper to do it that way.
However, I called renogy today and they said that their controllers couldn't work on the same battery bank, could have sworn i saw somebody else doing that

The charge controllers (CC) have to be fairly intelligent (not cheap) to be networked (multiple working together to charge a single battery bank). Since you have a fairly small array (1200 watts), a single CC will be sufficient.

A good 60 amp CC will output up to about 1680 watts (60amps @28 VDC) into your battery bank. This gives you some room for expansion.

If you mount your panels flat, you'll probably never see more than about 80% of rated output (960 watts) so a 40 amp MPPT charge controller will suffice.

Can it hurt a charge controller to send it more watts the bit supports?

I have been told (by Morningstar) that it will not hurt the TS-MPPT line of CC's - within reason. I have heard similar about the other name brands but never actually spoke to them about it. The CC basically clips off the excess power (more complicated than that but that's what it looks like to the user).

Are you planning on grounding to your frame/chassis?

I don't know really very new to this. Right now trying to determine if I should scale back the solar and go with an isolater to the alternator . Also considering not doing this and going 48v

It's all about your "mission" - how you plan to use your setup. There is no right or wrong just the reality of your style of living. Without knowing any of that it is difficult to comment with anything meaningful. That said, a 48VDC battery bank may not be ideal if you do not have a specific reason(s) for it.

I guess I am trying to figure that out too. Not full timing yet. More long weekends. I also like the idea of having some power when the electric goes out at my house. On the 48v. I already have the 8 6v batteries. Inverter charger cost not much different. And controller pretty close also. HD considered 24v also just for efficiency. So was like is my system too small for 48v.idk
