We use 1300kwh/m ($130)The Average home is 900kwh/m

One 10kwh battery would buy 23% of our avg daily load (43kwh)

We have a 3br house

Two might clear us through a peak time of day (46% of our avg daily load)

3 10kwh batteries would clear us through a peak time (69% of avg daily load)

But if it was cloudy, I’d like to go thought 3-4 peak times on battery, so I need 86kw

(9 batteries)

1 Commercial application power rack, the size of a fridge, would handle this 2 day load

But we would need 2 or more for continuous discharge. To go off the grid or through a blackout for 10 days form solar

we’d need the capacity for 5 power racks (430 of 500kwh)

0.5Mwh(500wkh) = 11d 14h

=

1/2

8Mwh (115% capacity for 4 families 40 days/nights)

I want these underground in a secret bunker
