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.

Re: panel wiring review please

it is a little too small for me to make out the diagram, but i can tell you, yes, it is generally a good idea to have circuit breakers before and after your charge controller.

as far as grounding, in small systems, it can be trickier without a larger dc load center that has identified positive, negative and ground busbars.

some of the cabin package schematics may help you.  we make every effort in designs to meet the requirements of the code.

Re: panel wiring review please

Thanks for attempting to look at it James..Smiley I used one of the schematics from the "Cabin" packages when designing it, as well as a few ideas from Home Power. I should post a better image of it, as I would really like to get a 2nd opinion on it be fore I purchase more panels, breakers and such. Could I possibly e-mail you the .jpg?

Thanks  James
