Tesla has officially opened orders for its next-generation Powerwall 3 battery on its website, after the company spent much of last year quietly deploying the new hardware.
You can now order a Powerwall 3 from Tesla directly through its website in the U.S., offering updated specs from the previous generation Powerwall 2. Tesla listed the specs for the updated energy storage hardware on its website in September, and it also caught the attention of CEO Elon Musk, who commented on the generation’s improvements after some Powerwall 3 installations had already been spotted.
At the time of writing, the Powerwall 3 doesn’t appear to be available in other North American markets, Canada and Mexico, nor does it appear to be available in Europe or Asia.
PW3 is optimized for ease of installation & high power, which means that a single Powerwall can serve as an uninterruptible power supply for most homes.
This is a big deal for ensuring that the lights stay on and you can power all your devices in the event of a power outage.
— Elon Musk (@elonmusk) September 8, 2023
Still, this is the first time that it’s been possible to purchase a Powerwall 3 through the Tesla website, and it appears you can no longer purchase a Powerwall 2. Tesla also made some price cuts to the Powerwall 2 in late September, seemingly indicating that the company was preparing for the product’s official launch.
The major difference from the Powerwall 2 are that the Powerwall 3 includes a built-in solar inverter and system controller, which the previous generation did not. In addition, Tesla says the Powerwall 3 is scalable up to four units, while the Powerwall 2 is scalable up to 10 units, potentially making it a better option for large-scale commercial projects that may or may not also require the built-in solar inverter. Musk also highlighted the peak power capacity of the Powerwall 3 as a major selling point for the new generation energy storage equipment in a recent post.
What matters most about Powerwall 3 is that it can handle peak power of ~30kW, which is enough to handle dryers & air-conditioners.
This means that a single Powerwall is now enough for most homes. https://t.co/UOKkkpVJCT

Users who have Powerwalls often report significant savings on utilities bills and the ability to keep the lights on during outages and other times of peak electricity demand. In some areas, solar and Powerwall owners can also participate in Tesla’s Virtual Power Plant (VPP) pilot programs, which essentially let you create massive, distributed batteries with other Powerwall owners to sell electricity back to the grid during peak-demand periods.
You can see the specs for the Powerwall 3 and last-generation Powerwall 2 below, as can be found on Tesla’s website.

Updated 2/17/24: Added CEO Elon Musk’s post on X following the announcement.
Tesla’s California Virtual Power Plant has quietly ramped to an estimated 5.7k homes

Tesla quietly doubled the size of its Cybercab fleet within the Robotaxi program in Austin, Texas, over the weekend to well over 100 units.
The move not only establishes more of the steering-wheel-less and pedal-less vehicles within the ride-sharing fleet Tesla has been operating for a year, but it also solidifies a more robust Robotaxi fleet as a whole.
Riders started receiving notifications from the Robotaxi app that stated: “Cybercab fleet has doubled: more rides available.”
I got this notification on the robotaxi app. They are saying the Cybercab fleet has doubled. Glad that they are advertising this pic.twitter.com/FFrnw4FRCF

Tesla first launched rides in the Cybercab in early September, although the Robotaxi fleet has been active for over a year, as rides began last Summer. Cybercab is truly Tesla’s most crucial vehicle release yet, as it is the first car any company has built that is geared toward full-fledged and end-to-end autonomy, never needing human intervention for anything.
Only available in Austin at the current time, Cybercab has two seats and has been spotted testing around various U.S. states and regions; Tesla plans to deploy the Cybercab in various U.S. cities in the coming months as a best-case scenario.
Tesla Cybercab gets initial tie-in to localized, in-house cathode plant
The availability of the Cybercab has doubled from just 58 units last Monday to 125 the following Friday. Marking a substantial increase in Cybercab availability, the additional ride-sharing units are more than welcome, as wait times for Cybercabs, especially, were quite high.
The dramatic increase is a sign that demand for Robotaxi is growing and Tesla is feeling more confident that its driverless ride-hailing suite, especially its Full Self-Driving software, is able to handle any traffic situation without explicit direction or supervision from a human being.
Tesla is advancing a fully automated pipeline for the 4680 battery cells used in its all-electric Semi, spanning production from Giga Texas through shipment and direct consumption on the line at the new dedicated Semi Factory in Sparks, Nevada.
The approach was outlined by Tesla at its September 24 Semi Handover event, which launched high-volume production at its new 1.8-million-square-foot plant in Nevada, which sits adjacent to Gigafactory Nevada and is designed for an annual production rate of 50,000 trucks per year.
After years of pilot builds and what was a four-year-long redesign of the truck, Tesla moved the Semi from 2170 batteries to its in-house 4680 cells, which are made in Austin. The change cuts battery mass and total energy while holding range, a key step in making volume production a realistic possibility.
Cells will leave Giga Texas in trailers, and at the Nevada Semi plant, Tesla intends for a dedicated line to unload those trailers automatically, station the cells, and feed them straight into pack and vehicle assembly.

Both Lars Moravy, Tesla’s VP of Vehicle Engineering, and Dan Priestley, the Head of Tesla’s Semi program, described the goal as a “zero human touch point” from the moment the trailer arrives in Texas until a finished Semi drives off the production line in Nevada.
The unloading system that Moravy and Priestley described is just one piece of a much broader automation push. The plant uses what Tesla calls the highest-capacity electric monorail conveyance in vehicle manufacturing, carrying frames-in-white simultaneously. Powder-coating replaces conventional paint, and many processes that would normally require operators have been designed out.
Tesla has repeatedly said that “the best part is no part,” and the cell-handling plan extends that philosophy from the cell factory floor in Texas all the way to final assembly in Nevada.
If executed as described, the closed-loop flow would reduce labor, handling damage, and inventory buffers while tightening quality control on a component that represents a large share of the truck’s cost and weight. It also shortens the physical and organizational distance between two factories separated by more than 1,200 miles. The Semi itself now shares a bar-wound stator and other components with the Cybertruck, further linking Tesla’s passenger and commercial production systems.
High-volume output is expected to ramp gradually after the first trucks left the new line in April 2026. Early customers include PepsiCo, DHL, and U.S. Foods. Whether the automated trailer-to-line process reaches the promised zero-touch standard will be visible in the coming months as production scales. For Tesla, the Semi factory is another test of how far it can push “the machine that builds the machine” across sites.

Elon Musk’s AI Grok Bot can now handle banking while your Tesla FSD handles the road
Elon Musk says Grok Bot can manage your finances through linked bank and investment accounts.
Grok Bot now wants access to your wallet, with SpaceXAI rolling out a new Finance integration for its agent platform that lets users link bank, credit card and investment accounts thereby letting their Bots help manage spending, investments and more. Elon Musk amplified the announcement on X with a short endorsement, “Grok Bot can manage your finances.”
The feature builds on two earlier steps. In early September, Grok gained the ability to answer questions about spending, savings, investments and cash flow using accounts connected through Plaid, starting with users in the U.S. Before that, on August 28, SpaceXAI let Grok Bot buy things online through Link, with users approving every spend request and the Bot receiving a single use card for each payment.
Musk has already shown how far he wants users to push it. In late August, when Tesla investor account Teslaconomics said he was weighing whether to give Grok Bot access to his bank accounts, Musk replied, “Try it out. If Grok Bot messes up, we will make you whole.” That promise goes beyond SpaceXAI’s consumer terms, which make users responsible for what their agents do and generally cap the company’s liability at the greater of fees paid or $100. SpaceXAI’s own documentation recommends requiring approval for purchases and financial transfers.
For Tesla owners, the update lands five days after Tesla brought Grok Bot into its vehicles, letting drivers hand off errands by voice while FSD (Supervised) handles the road. Bot access inside the car is currently limited to SuperGrok Heavy subscribers, though Connectors are open to anyone signed into Grok. With Finance linked, a driver could ask for a spending summary or a check on upcoming bills during the commute.
Grok’s role in the car has grown quickly since Tesla’s Summer Update let it control cabin features by voice. We have been using Grok Bot in our own Tesla for several weeks, and here’s how our latest test went.
