What is your reason for skepticism of lithium batteries? The Australian megapack that caught fire during debugging? Hoverboards on airplanes? I ask because I have a powerwall under the floor where i'm sitting right now and zero hesitation about it. Indeed, with my ~6.5kw nominal solar, I am essentially net neutral. The car in my driveway has a lithium battery 5x the size and hits 50 degrees during this heat wave. It also charges at about 3x the rate. So the relatively cool crawlspace seems like a totally normal place to discharge at 5kw? If you go with another chemistry, I think you'll find that cycling from 100% to 0-20% daily will not last for many years..
