Yes the real breakthrough tech needed is a new battery! Which hopefully Tesla is on track to develop,because as is, electric cars are just not scalable.

People say that, but from what I've heard there is plenty of lithium in the world to increase use 20% every year for 30 years before we need to get more creative in how we mine it. That's a huge total increase and means that electric cars totally are scalable. Do you have information supporting the idea that electric cars aren't scalable? My understanding is that they definitely are scalable.

Charging is where the scaling problems come in. If everybody in your neighborhood plugs in their Tesla at their home at night and/or at their office during the day, it will likely cause brownouts and blackouts in areas with grid service that's already marginal for current demand. Hence Musks's interest in load-shifting technology.

Really? According to wiki, India's middle-class makes anywhere from $10 to $50 per day. When you factor in that this will cost a lot more than $3500, would these really sell like crazy?

For a small percentage (just enough to match inflation), I'd gladly loan an Indian middle-class family the money.

Great idea. I can't afford to loan this amount, but I do make micro-loans regularly on kiva.org. Would love to see some loans appear there for these kinds of power systems.

This is much more groundbreaking than it may appear. The innovation is entirely in the price. At $3500, you can put in two and be entirely off grid. Solar panels are cheap enough you only need batteries to last one night, as you can size the array to operate your loads even on cloudy days.

2 is not enough. 4kW seems to be the maximum potential drain from the battery. That wouldn't power an oven… let alone anything else at the same time. 4kW inverters seem to be around the $1000 mark… but they don't seem to increase linearly (10kW inverter $4000 for example). Of course you could go totally off-grid, but the cost isn't going to be just $7k… it's likely to be at least $15-20k by the time you get everythin…

The key to successful Solar Living is an understanding of energy efficiency.

Suggesting running an electric oven on solar is crazy talk.

I feel like a backup generator is the last place where I would make my decisions based on the environment. I mean how long is it actually going to be active? Also batteries aren't exactly environment friendly either.

That may well be how you feel, but lately I feel like any burning of petrol is just disgusting (though I still do it as I cannot afford alternatives at the moment). I want to completely divest from fossil fuels, even for intermittent use. That's as much for the social value of saying "yeah I don't use fossil fuels and it's great" as it is for the environmental impact. I want to try all this tech to be an early adopte…

Isn't that a bit of an overreaction?

You might want to reevaluate any moral position you have where a significant basis of your values is the ability to brag about them. I would be fairly disgusted if someone said a significant amount of the reason they're so devout in their religion was so they could boast about it with their peers.

I hope they have taken the safety technology from their Tesla vehicles and put it into their Tesla Energy batteries, because the thought of a 10Kwh lithium-ion battery exploding in my garage does not sound like the kind of mess I would want to be cleaning up. I couldn't see it mentioned anywhere, but presumably these batteries will be available in Australia for the same price? We always get charged more. If I can get…

They certainly won't be $3,500 AUD.

3,500.00 USD = 4,447.86 AUD according to xe.com right now...

That, and the factory is in the USA. I would assume shipping something that large and heavy would add to the cost in Australia.

But they could now, and most deep cycle lead acid batteries are flooded, not sealed, which means they have to be ventilated to prevent hydrogen explosions hazards. Not so with Tesla's offering.

Fine. 4.8kW Li-Ion battery for USD$3,278 1.9kW for USD$1,678. My point is that Tesla isn't really doing anything really unique here. Sure, they're giving it more press than anyone really has before, but the products aren't especially cheap, innovative or special. http://ironedison.com/12-volt-lithium-battery-for-solar

What about the power wall for utilities. I haven't heard of any other similar offerings. That seems even more important than the home based ones. Plus open sourcing designs to the gigafactory. Hey Branson want to step up and build one on your side of the pond?

A notable beta user: AWS will be running a 4.8 megawatt hour pilot program with Tesla's batteries in the us-west-1 AZ (Northern California). Hopefully this allows AWS and other hosting providers to use intermittent, renewable sources of energy more often. EDIT: I'm guessing AWS will be using a cluster of 48 power packs (100 kilowatt hours each).

This might be a reason to move your production environment out of us-west-1 for a few years.

I wouldn't want any experiments going on around my main servers.

Dont count on it, we also get the product release lag for things like this too. Buying a Tesla Car here is at least double what it is in the US too.

hahaha less than zero chance these would be in oz for that price.

Comparably the USD3500 price is pre US state sales tax. Its really $3850 (assuming 10% sales tax) after costs and converted today is AUD4891.50. Given historical price discrepancies in Australia of +40%, you are prob looking at AUD6800.

> At that price, you could've bought a larger capacity deep-cycle storage solution already readily available on the market with batteries that will last 20+ years. Citation? Deep cycle lead acid batteries have a maximum life expectancy of 5-8 years, even if aggressively managed.

My 2200ah Lead Acid bank is still healthy after almost 20 years.

Just did some load tests yesterday.
