In a power blackout, you really need only to keep your refrigerator running, and a freezer if you have one. And, perhaps, a light for where ever you are at in your home. That is a lot less than one kw per hour. We keep about ten of those dots with little leds in them that you can mount to the wall for emergencies. That covers most of the light needs. So the Powerwall would be a worthwhile investment in an area prone to blackouts.I didn't say you could charge your E Vehicle with a powerwall.it is NOT sufficient to take your home "off grid". Barely enough to run a load of laundry -- never mind heating or air conditioning or an oven. OR charging your EVehicle
But 10 kwh are definitively enough to power a home, at least for a couple of days.
Avg home consumption is somewhere near 1KW per hour. You live in a Yurt? An NYC apartment?
And the "powerwall" is 7KW-hrs for about $7000 installed.. Not 10...
And why are we discussing homes anyway? Don't you know there's an economy to power? You want to go to hospital and end up in field tent like some 3rd world place??
