Ann: Altech - Two 60KWh Battery Pack Prototypes in Production, page-3

highest for multiple family households (20 kWh/day per household) followed by couples with children (17 kWh/day per household). lowest for those living in single person households (8 kWh/day per household) and group households (12 kWh/day per household).
(From CSIRO study)


60kwh would be a reasonable size for domestic/home.
~3 days coverage/irregular high use & home solar gen is not at its best. Noting size of typical solar install of 5kw is now up around 6.6kw mostly due to panel efficiency improvements. (Solar choice)

interested to see est. cost/kw for this size & will have to check if they show depth of discharge for these batteries.
