US residences currently use ~1kW per household. This means that current car-battery sized storage (~100kwh) would already last almost a week.
Note that other western industrialized nations are significantly less wasteful with residential electricity; the same storage would last the average german household already over 2 weeks for example. Part of the difference might be explained by air conditioning-- but this conveniently requires very little storage anyway.
