1000 cycle lifetime would mainly be if you were doing full charges and discharges (10-90% charge/discharge or worse). This is from mid 2018, but you can see that model s/x batteries were hitting about 90% capacity after 250,000km which is verrryy roughly 700-800 charge cycles. https://electrek.co/wp-content/uploads/sites/3/2018/04/screen-shot-2018-04-14-at-2-56-15-pm.jpg?quality=82&strip=all https://electrek.co/wp-content/uploads/sites/3/2018/04/scree... Grid storage batteries are going to be charged and discharged at more reasonable rates than cars. Tesla's superchargers run at 50-250kW and discharging is going to be above 1MW at times, which is not kind to batteries. I think you can expect quality grid storage setups to last 2000-3000 cycles at this time depending on their environment. Keep in mind that these cycle lifetimes are to 80% life, so if you're willing to go down to 50% capacity you can expect longer lifetimes, probably closing in on 15-20 years of use.
