PowerWall and "The Missing Piece..." Event

"oh by the way, the entire night has been powered by solar from the sun stored in batteries"

Can stack up to 9 home batteries (90 kWh)

With choice of colors. Perhaps to match your Model S?

 

[Robert.Boston]

this would not let one go off grid unless you live near the equator, or have a huge number of solar panels.

You can stack up to 9 of them. 90 kWh gets you through a lot of sunless days.

I want the one with pink polka-dots.

No inverter!? Why not make it an all in one solution? Now I have a battery, AC/DC inverter and a PV inverter.

Not sure of the reasoning behind that choice when Elon is talking about an "all in one" battery solution.

 

[Owner]

That's not the issue. Power generation is extremely seasonal. I'd need a lot more than 90kW to get me through the winter, or I'd probably have to double the number of solar panels.

You can stack up to 9 of them. 90 kWh gets you through a lot of sunless days.

2 billion power packs mehehe!

Exactly!

This is awesome. Elon sees the future, and there is a real solution. It's totally reasonable, and achievable. Years ago I remember a Scientific American article demonstrating that the USA could be powered by 100 sq. mi. of solar panels. But storage was the obstacle. No longer.

DC/DC converter is included. 2kW Inverters are provided by SolarEdge.

Very nice. Met my expectations. It was interesting, he really treated it as a chance to zoom out and remind us of the big picture.

 

[CapitalistOppressor]

Loving this.

$350/kWh for the light duty backup power model and ~$430/kWh for the high duty deep cycler, which is much more akin to the requirements of the utility packs. Anything in the $500/kWh price range for utility applications is a game changer and will instantly make Tesla the dominant player in the industry (which is frankly what we expected years ago when discussing this).

 

[ChrisH]

Pardon my slowness, but how would this work for someone like me? I do not have solar panels on my home. How would this benefit me?

 

[Sosius]

Oh yeah. The techno music loop is back on.

 

[3s-a-charm]

So its not a motorcycle? Darn - lost that bet.

 

[Dutchie]

And then it was over. I feel a bit letdown. He was not himself today. Maybe a bad day for him..

 

[joefee]

Wow: powering the world...estimates to the stock pre announcement were $30 to $100 per share ... we will see tomorrow if we get a gap up.

You're application would be charging up from the grid and if there were a power outage, having backup power. Also if you had access to a variable rate plan, you could charge your Tesla Powerwall at a time when your utility rates are lowest and then use the battery to minimize your load during peak power prices.

What is going on with the distinction between the 7kWh "Daily cycle" and 10kWh "backup applications"?
