It seems that Tesla has started sending potential customers information about an upgraded Powerwall, rightly called Powerwall +. In a post on Reddit spotted by Electrek, a user submitted a specification sheet to the battery along with photos of what it would look like when installed. The upgraded version battery capacity is still 13.5kWh, but its maximum power is now 9.6kW, up from 5kW continuous and 7kW peak output. That said, power-ups are only possible when you’re in off-grid mode.
The specification sheets describe Powerwall + as follows:
“Powerwall + is an integrated solar battery system for storing energy from solar production. Its integrated design and streamlined installation enables a simple connection to any home, and improved surge capability provides entire home backup in a smaller package. The system̵7;s smart controls allow owners to customize system behavior , to suit their renewable energy needs. ”
Tesla CEO Elon Musk started talking about an upgraded Powerwall 2 on Twitter a few days ago as one apart from his announcement that Tesla’s solar panels will only be sold as a package with Powerwall. The company “can unlock higher capacities for free via software update next month,” he tweeted, adding that the battery may get a power increase of over 50 percent at 30 degrees Celsius of ambient temperature depending on the production date. During the company’s recent earnings call, which revealed that it was selling more cars in the first quarter of 2021 than ever before, Musk said Tesla started production of the upgraded Powerwall around November 2020.
The specification sheet distributed by Tesla also shows a photo of the new Powerwall installation. The battery itself does not look different from the other versions, but the new installation comes with an inverter that has an integrated switch. As the original poster that received this specification sheet completed their order for the Tesla solar, future solar customers may be able to get this Powerwall setup.
