Tesla cars are a fad, not their version of the battery bank. Until the price point of an electric car comes down to the point that every day masses can afford it, and the battery technology progresses past the limitations we've been bumping up against for the last decade, nothing will change. Teslas will remain a play toy FAD for the rich and "look at me, i'm trending!" crowd.
The cars require a lot of juice to recharge. If you want quicker charges it requires a **** ton of amperage draw, even on the 220v plug.
You think air conditioners causing brown outs and the government screaming at us to cut down use will get better or worse with thousands of electric cars sucking on the grid at the same time? Our electric grid already is worn out and in dire need of upgrades. No way would it be able to sustain hundreds of thousands of cars in a metropolis plugging in at the same time.
Onto the Tesla power pack. 7kwh battery bank. Excellent. You cant do squat with it. First of all, they are built using Lithium Ion batteries. Wanna discharge that thing using its full 7kwh? 100 charges give or take the pack is done. Discharge it 80%, what is recommended for hard use and you'll get about 500 recharges. But then you only get 5600 watts out of it.
Really want to make it last? Discharge 50% and you'll get approximately 4000 recharges out of it, but only 3500watts.
3500 watts cannot run anything. Average house hold uses 20kwh daily. So the battery bank will be able to provide two, maybe three hours of usable power.
Looking at other specs, it doesnt even include an inverter. That alone costs upwards of $1500 dollars for an okay one and 3000 up for a decent one. If you truly wanna be green then you have to recharge this bad boy using solar power. At cheapest being $1 a watt for solar panels, not including installation and brackets, chargers and other miscellaneous items needed you are looking at 5 to 6 grand for a basic 4500watt solar panel system.
So we've now invested between 7 and 10 grand so that we can do what? Have usable power during a black out for 2 to 3 hours, or offset my electrical bill from a high rate of 16c a kw to 8c a kw? Whats the break even point of that?
No, the solution is signing up for micro-fit program and getting paid 35c a kw. Thats where the future is.

You are obviously right. Not a shock that you know what we all do. But he is offering a simple packaged version. Old(ish) product, new packaging. Nothing new for sales industry. Did you happen to price out the install for your new house?
He mentioned that he was hoping that other companies do this exact thing he is doing to help drive the model forward, and since you are executing this idea on your own house, seems that you do like this idea. More so than anyone just stating they "want it". I guess its not a "big deal", but its a product that makes it easy to be off grid. Scalable for size. By a brand that is known for advancing battery technology.
LOL@mcmansion.. its true that habits and patterns must change but it has to start somewhere, and I don't see Duracell offering this type of system for homes. If these systems already exist, they are by small companies, and they systems are nowhere as refined. Arguing about how shipping and manufacturing globally causes more harm does not detract from this technology AT ALL.
I don't understand how you of all people could call this a passing fad when you are planning on doing a variation of this on your own home. I can't see how removing yourself from the energy grid (effectively) could be seen as negative in any way. Now the question is how much does your system cost in comparison and effectiveness to this system.
I suppose to a point if this tech becomes more prolific there will be other brands to choose from giving people choice, and certainly price variances.
