My planned design -- feedback welcomed

[MJSullivan]

I recently purchased a complete "DIY" system from Northern Arizona Wind & Sun and the parts have (mostly) all come in. Now is the time for me to roll up the sleeves and begin the installation, starting with the basement in this antique barn I call home. While waiting on the parts to arrive, I took it upon myself to carefully measure the space I have to work with and have created a design that I plan to implement barring any revisions from the advise I receive from this forum (see attached photos). While I will install & hang all the components, I plan on hiring a licensed electrician to do the actual wiring & commissioning.

BOM

Never having done a "Single Line" diagram before, and in preparation for the permitting process, I thought I'd try my hand at one.
To my eye it looks pretty good -- have I missed anything that might perturb the AHJ ?

Comments/feedback welcomed.

With some feedback from others, I've updated my basement inverter/charger/battery layout.

I think this is getting much closer. Feedback still welcomed.

The goal is to start installing things this weekend.

Hi Michael,

What software did you use to create your design? I am currently making mine in Visio but yours looks so much better.

I use Affinity Photo/Affinity Designer. Basically, an Adobe Photoshop/Adobe Illustrator clone. No magic. Just a lot of work!

I will try it out - Thanks
