I am weighing a home battery now, and I see that you can get the chemistry & cycles often at around 4000-6000 cycles at a reasonable DoD. I am looking to get a lot of life out of the right setup , If i properly size and managed the system. However, I know that not all systems age the same way.

If you’ve been running storage for 3-5+ years, can you add parallel packs without redoing the whole system ? What about the firmware updates, have you ever lost compatibility after an update ? I know this can be frustrating if I plan to scale over time. Did you expand or replace ? What failed first your cells, BMS or inverter integration ? Do you have any regret about closed ecosystems or discontinued models ? Did your capacity fade faster or slower than expected ?
