Tesla confirmed having discontinued the 10 kWh Powerwall for backup power to focus on daily cycling version

We noticed that Tesla removed references to its higher-capacity 10-kilowatt-hour residential battery from the Powerwall website (and the press kit) some time ago, but today GreenTechMedia received an official statement from a Tesla representative confirming that the larger capacity battery has indeed been discontinued…

“We have seen enormous interest in the Daily Powerwall worldwide,” according to a statement provided to GTM. “The Daily Powerwall supports daily use applications like solar self-consumption plus backup power applications, and can offer backup simply by modifying the way it is installed in a home. Due to the interest, we have decided to focus entirely on building and deploying the 7-kilowatt-hour Daily Powerwall at this time.”

At the original unveiling of its new home battery system, Tesla said that there would be two versions, a smaller capacity 7-kilowatt-hour model priced at $3000 and a 10-kilowatt-hour for $3500 — both for different purposes. The 10kWh battery was to be optimized for energy backup, while the 7kWh system is for daily use. Tesla seemingly suggests that the latter has received much more interest.

This news comes as just couple of months ago we learned that Tesla Motors is already planning to release a second generation Powerwall, its home energy storage system, sometime during summer of this year. During a recent exclusive event for Tesla owners in Paris, Elon Musk said that “version 2 of the Powerwall probably around July or August of this year” and that the new version “will see further step changes in capabilities.” It’s possible that Tesla is planning to reintroduce the 10kWh model later this year.

    I suspect Powerwall 2.0 will be another Daily Powerwall but with higher capacity, higher power, and lower cost per kwh.

    Better wait fornbigher capacity daily cycling battery. 7kw doesnt really cut it for a house.

      It depends. We use ~8kWh/day, and that’s a lot when comparing to other households, but we don’t have a house, just a 60 m^2 apartment.

      Most households in Germany would probably be fine with 7kWh/day battery storage. Some solar power can be used directly without going through the battery, and remaining kWh can be stored in the battery, and 7kWh should be enough for the evening/night. When the battery is at 100%, additional kWh can be fed into the grid for ~0,12EUR/kWh.

      • Household power usage in the states varies hugely depending on where you are and the season, but we use anywhere from 15-40 kwh/day on average.

      Figure your daily need, divide by 7, round up. Hook multiple PowerWalls in parallel. Obviously you will need to size your PV array accordingly. Or go on a power diet.

    Very interested. Waiting for the future to happen

  4. Frank - 7 years ago

    I would imagine powerpack v2 out in July will fall between 7kWh and 10 making two tiers pointless.

    wait for a 10kwh for $350
