RNK. I think you have a good plan, especially with your erratic grid.
That’s a great price on your batteries. When I was weighing alternatives that led to my Aquions I was hopeful for the Powerwall but also didn’t consider the other Lithium options ready, especially at the cost.
I could have replaced my Rolls Surettes but prices had doubled to over $2k each plus installation. A second alternative was used 2v submarine batteries for $250 each, but installer wanted over $2k for install and wouldn’t sell for self install. Hindsight either may have been wiser option. My 1st Rolls lasted 9 years and the submarine bats should last 3-5. Either a more cost effective route to where I am. If only we could turn hindsight into foresight
Racking is insane. While we often concentrate on the major components the in between parts add up fast. When I redid our PV I repurposed the original rack and added to it with aluminum, 2x2 angle and square tube for adjustable legs and stainless steel fasteners. Had I the luxury of time most likely would have gone similar route for the batteries but installation could occur as early as Wed and the rack is only part of my prep work. Minimum work for installer, delivery, wire to existing combiner, and commissioning. All with my help of course.
I would not use steel for my PV due to wx. Know it would rust out. The batteries will be in my tractorshed, protected from wx. I do plan on priming and painting to delay the rusting.
