Tesla Introduces Powerwall 2 With Double The Battery Capacity

Tesla has introduced its long-awaited Powerwall 2 for households and Powerpack 2 for businesses.

The updated Powerwall includes two 14 kWh lithium-ion batteries, more than doubling the capacity of the first-generation pack and the company says it is capable of powering a four bedroom house for an entire day with lights, refrigerator and other appliances. Powerpack 2 meanwhile has a 210 kWh capacity and can be scaled up indefinitely by combining multiple Powerpacks.

Additionally, a power inverter has been incorporated into the Powerwall 2 and Powerpack 2 whereas the originals had a separate piece of hardware. The new ones are also able to work alongside Tesla’s recently-introduced solar roof tiles.

Compared to the original Powerwall, the second-generation one also adopts a different design, ditching the curvy design in favour of an angular look and with a flatter design. Each unit will be priced at $5,500. During a Q&A at the Powerwall’s introduction, Elon Musk said he anticipates the firm to sell more Powerwalls than cars.

    I love this guy.

    Wouldn’t it be great to see the fossil fuel companies execs reading this sort of stuff whilst their ring-holes are in spasms.

      Why do you think that battery company exec’s will be any different from oil company exec’s. People with that kind of money are only looking after themselves.

      Save us your uninformed 13-year-old eco-warrior rant.

      You drive a car? Take a bus? Fly on a plane? Use plastics in everyday life (oil = plastics) You are a hypocrital idiot then…

      Spend less time yapping about “oil executives” and more time trying to explaining and solving why all those solar panel vcompanies went bankrupt and eco energy industries are full of corruption and incompetence…

        Everyone just wants to get rich. Nobody really cares about saving the environment. Not enough to cost him/her real money, anyways. Producing new and disposing old batteries are more hazardous to the environment than just using an economical internal combustion engine.

          then come up with a solution genius…then u can be rich too

      • Knotmyrealname

        Sheesh, this guy wants to sell us products that unleash us from what we do now. Use the sun, charge a powerwall, charge your car, drive away. What’s the big issue with that? Oil companies and cartels border on the psychopathic. Look up how they love to shut down anything that threatens their existence. Plenty of evidence. Yes, I drive, yes I use plastic. We all do, too much frankly. Time for alternatives.

      • Big Black Duck

        when we use something because we have no choice does not make us willing participants…stop making such assumptions

    The first one can power a home for a day at $5,500? That’s too much for too little, so I’m glad they’ve made improvements. I just had a natural gas whole house generator and sub panel installed to finish my basement for $5,500. And I only have to pay for NG if/when my power goes out… and it will last for more than a day or two. I totally believe in cleaner, renewable fuels, but this is my solution for now. 😉

    Hope they can actually make money on it. Because their cash flow is negative right now, solar business a disaster, and the Model 3 is still nowhere on the horizon.

      Money is not everything u know

    Ordered a Powerwall in the States over a year ago. Still haven’t received it.

  • Would be cool to install these in gyms, and configure various machines such as treadmills and bikes to charge it up upon use…. add to that the solar panels it could potentially save businesses a significant sum every year.

    • Big Black Duck

      yup i had that idea 5 years ago… it would be good if they install cycles that can actually recharge your power wall… I guess its the next step..lets hope they figure this out like you and i did

    • D3X

      Problem is, human generated energy isn’t really that much. you can have one guy run on a treadmill for hours and it’ll just be 20mins of battery charged as opposed to using more energy by supplying the lights, treadmill and other things for the facility.

      • Fair point. Battery technology is rapidly improving however so future iterations may allow for quicker charging, making such an idea feasible.

        • D3X

          Actually, it’s newton’s second law. The amount of force translated to energy that a human can generate from sheer force from exertion is miniscule compared to solar energy or other forms of renewable energy (hydro etc).

    Lots of Tesla fanbois here…

    No one has an issue that this isn’t car-related?
