This is depressing. I had never really considered chronological age when looking at batteries. The longevity is really important for the ultimate economic viability and I’ve been tracking that to decide when to pull the trigger on a home battery. A 6000 or 10 year cycle rating means functionally 10 years for a solar deployment because you are only cycling the batteries 1x per day. I was hoping you could get 20 years out of such a system (thus halving the cost). Bummer.

Unless you live in California, and use a "time of day" meter [for kWH offsetting], there are few reasons you would need at-home battery storage (other than power outages... get a gasoline generator, instead!). Direct-tie inverters utilize "the electric grid" as your battery/capacitor... unless you are off the grid. Also, there is a glaring safety defect that violates UL, contained within every Tesla Powerwall 2... so don't get one of those.
