Serious question: Can anybody who's familiar with the energy storage field explain the nature and magnitude of the innovation here. Is this just a large lithium ion battery with some electronics added for charge/discharge control or is it a bigger deal than that? Perhaps the innovation is in packaging and productizing it for the various market segments?

The details are up on the site: http://www.teslamotors.com/presskit/teslaenergy The Powerwall is available in 10kWh, optimized for backup applications or 7kWh optimized for daily use applications. Both can be connected with solar or grid and both can provide backup power. The 10kWh Powerwall is optimized to provide backup when the grid goes down, providing power for your home when you need it most. When paired with s…

Does anyone have any experience with the pricing here and could elaborate a bit wether or not this is a good deal? This does seem enticing at first glance, but I am unfamiliar with any hidden costs there might be in going with a solar + backup system such as this.

The innovation is all in the price.

"Can anybody who's familiar with the energy storage field explain the nature and magnitude of the innovation here."

-Not me but clearly this is v1.0 and likely v3.0 is where you will have huge impacts. Similar to a Tesla costing 35k for their v3.0. The giga factory will probably play an even bigger part here as batteries should scale better than cars. So battery v3.0 should be >>> than electric car v3.0.

It'll be interesting to see how this is pitched and what it's price point is... I'm still not convinced that energy arbitrage is profitable enough for individual homes given the current cost of the storage.

We have a fairly large 100% electric home built in 1980 (after the oil crisis government promised "all's going to be nuclear & cheap real soon now") ... don't underestimate the electricity & heatings costs on large properties

I'm curious if they'll be indemnifying homeowners for fires originating in the battery pack. Anyway, if it can clearly save me money and is not incredibly expensive up-front, I'll likely get one. Even if you actively conserve, electricity is decently expensive over the long run.

Presumably they're using a stable form of lithium ion battery, does anyone know? Maybe something similar to A123 Systems' lithium iron phosphate?
