Tesla Sends Updated Powerwall + Specifications to New Customers

Tesla recently announced that it would only start selling its solar products bundled with Powerwall. This is an important step for giving people energy security and makes the Powerwalls in one area a giant distributed utility. With a great emphasis on home energy storage solutions, Tesla has increased the performance of Powerwall and is now sharing its specifications with its new users.

Tesla previously offered solar products and home energy storage systems to customers as two separate products, however the company changed its approach last week. Tesla CEO Elon Musk said that now the Solar Roof or Solar Panels will only be sold together with Powerwall as one product. Musk also shared some updates on Powerwall. He revealed that the new Powerwall, which began production in November 2020, has a lot more peak power capability than the specification on the website—actually about twice the power.

Now, new Tesla customer u/tangarg/Reddit, who is currently finalizing his design with Tesla solar, has shared new details. In the process of setting up the system, the company sent him the specifications for the new Powerwall +, which will come with solar products for his home.

According to the description, Powerwall + has an integrated battery, inverter, and system controller for a more compact install. Basically, customers get more functionality in a smaller package.

"Powerwall + is an integrated solar battery system to store energy from solar production. Its integrated design and streamlined installation allow for a simple connection to any home, and improved surge power capability brings whole home backup in a smaller package. System smart controls enable owners to customize system behavior to suit their renewable energy needs."


  • Integrated battery, inverter, and system controller for a more compact install
  • Integrated soft starter capable of powering motors and air conditioning units!
  • A suite of application modes, including self-powered, time-based control, and backup modes
  • Wi-Fi, Ethernet, and LTE connectivity with easy over-the-air updates

As Musk described, the energy capacity of Powerwall + remained the same 13.5 kilowatt-hours. But power, which was previously 5 kilowatts continuously, and peak power of up to 7 kilowatts, is now defined as continuous power on-grid 7.6 kilowatts and (in the event of a power failure) continuous power off-grid up to 9.6 kilowatts. This means that Tesla's home battery can power more power-hungry devices at the same time.
