panel wiring review please

I'm on my way with a small system now. I just got my 1st Kyocera KC40T panel and other items and am going to order a 2nd panel probably tomorrow. I know I should have an electrician look at this schematic, but I'd like to have a sense of how the system should be wired for my own piece of mind. I've designed the panel based on a minimal budget with the hopes of eventually getting to a pair of controllers and 6 total KC40T panels. I know it's not a big system by any means, but it should get my studio completely off the grid.

I would really appreciate some feedback on the schematic I'm proposing to use for my power panel. A couple of things I'm still a little foggy on.

does my system ground look right?
do i need a breaker between the controller and battery, even though I can "technically" disconnect the combined array at the baby box?

as always, thanks so much for the help. Everything I learned up till now has been through this community and I'm definitely still learning.
