.2% warranty claims for all causes. There manufacturing plants must be freakishly precise, quiet, clean, orderly places, "giga factories" where they do production runs in the dark, as there are no humans present or needed untill scheduled maintanence is done. CATL is commisioning a sodium battery plant this year which will very likely be a game changer for several power storage use cases that do not require ultra high discharge rates or the lowest weight, but where saftey, low cost, and longer service lives are important. For remote power storage, backup power, and off grid, the integration on PV, batteries and car charging into a standardised system will be a huge boon, settling on a voltage, likely?, 440, for batteries and PV line voltage, that can then integrate with car batteries will reduce the size, complexity and cost of the whole system.Actual household plug voltage would of course be the same as what people use now, but system voltage would be best at a higher voltage for car bateries, and transformers/transmission lines, pv line voltage.
