a new battery

From what I've read, this will change everything about home solar independence:

https://en.wikipedia.org/wiki/Vanadium_redox_battery

I have a masters in Electrical Engineering. I've added many home-energy reduction systems like zone-fans for AC ducts, off-grid solar water, and soon, closed-cell foam.

But the economics of solar power, especially since Florida is in the dark-ages about buying it back, are daunting. This new battery technology looks promising! They're bulky but for us, space is no issue.

RE:a new battery

Thanks for the link. We're still (after almost 20 years) using a temporary grid hookup because I don't want to truck a ton of lead onto my place and maintain it. I've been waiting to see a well-supported and distinctly better fixed-station technology become available. It was close with the iron / manganese chemistry, which I like because it's nontoxic and uses abundant elements, but its leading developer went bankrupt. The vanadium chemistry is technically superior, but of course uses a a rarer element. I wonder if it will appear on the home-solar market with vendor support? That support is crucial for us, since I don't have a degree in electrical engineering, and the significant other sensibly doesn't want to depend 100% on yours truly to keep the power on.

The sulfuric acid aspect is a bit daunting!
