As we previously reported, the biggest difference with the Powerwall 3 is a higher power output of 11.5 KW continuous and an integrated solar inverter.
The company continued to use both the Powerwall 2+ and the Powerwall 3 based on what made the most sense for each installation and as it ramps up the new unit.
But these are just some of the improvements that the new Powerwall 3 is bringing. Tesla is still working on a few more things enabled by the Powerwall 3 technology.
Tesla has now produced a webinar for its installers about the new Powerwall 3 that revealed a few more interesting details.
Again, there’s no doubt that the power and load capacity is the biggest upgrade of Powerwall 3:
Most Powerwall 2 installations involved more than one unit, but that had to do more with the power limitations than the energy capacity. Households needed more continuous power capacity to run critical electric equipment on the battery pack.
With the same 13.5 kWh energy capacity, a single Powerwall 3 can power an average household for hours.
For those who need more energy capacity, Powerwall 3 is also going to be easier and cheaper to stack.
Tesla says that it is working on a new version of the Powerwall 3 without power inverter components to stack with a full Powerwall 3.
This new capacity means that you can combine 4 Powerwall 3s together for a power capacity of 46 kW and energy capacity of 54 kWh, but that’s a weird power-energy mix that is not ideal for most projects.
However, this upcoming new stackable units without power inverter, which Tesla calls ‘DC Expansion’, means that you can do a different configuration focused on adding more energy capacity:
A single of these units on the right (one full Powerwall and 3 ‘DC expansions’) would theoretically have a continuous power capacity of 11.5 kW and an energy capacity of 54 kWh.
The upcoming DC Expansion unit is going to be $1,000 cheaper than the Powerwall 3, which is listed at $9,300 before incentives.
In the webinar, Tesla also confirmed that Powerwall 3 is using LFP battery cells, like its Megapack.
The less energy-dense battery chemistry is ideal for stationary energy storage projects as it offers better longevity.
Tesla currently offers $500 off Powerwall orders if you place the order with a referral code. The energy storage unit is also eligible to the 30% tax credit.

A new report states that Tesla will pause part of new Model Y production at Gigafactory Shanghai for 3 weeks to upgrade the lines.
The shutdown will extend beyond the regular Chinese New Year.
The Chinese New Year is technically 2 weeks long, but the official holiday lasts a week, during which significant parts of the country’s industries shut down.
That includes the auto industry and Tesla, but it looks like the American automaker plans to do things a bit differently this year after having just started production of its updated Model Y at Gigafactory Shanghai.
According to a new report from Bloomberg, Tesla plans to shut down part of its new Model Y production lines from around January 22 to February 14.
In comparison, Tesla only plans to shut down production of the Model 3, the only other vehicle produced at the plant, from January 26 to February 3.
Tesla only recently started production of the updated version of its best-selling electric SUV. The report states that the automaker will take advantage of this extended Lunar New Year shutdown to upgrade parts of the production lines in order to streamline and ramp up production capacity.
The automaker delivered about 480,000 Model Ys in China in 2024 – up about 5% year-over-year.
It makes sense. Over the last few weeks, Tesla has basically been running a pilot of production of the upgraded version, which is entirely different from the previous version, but there are enough differences that new parts and processes can create bottlenecks.
Tesla likely found ways to optimize production during that time and now will implement it during this extended shutdown.
We will try to keep track of the Model Y production and rollout in China as any delay or production issues can be extremely impactful, considering the Model Y is the world’s best-selling EV and China is the biggest EV market.
Any kind of issue there can be extremely impactful on Tesla and the broader EV market.

American Honda shared a business outlook for 2025 during a recent briefing with the media. In terms of electrification, the next 12 months for Honda will be much of the same: facelifting tried-and-true ICE models like the CR-V and Passport. However, there was one exciting piece of news from Honda on the BEV front—the automaker has confirmed it will begin US production of an Acura RSX EV.
Honda and its premium sub-brand Acura, for that matter, are getting more and more coverage on Electrek’s homepage thanks to the combined efforts in adding new BEV models… although that transition has still been relatively slow compared to other OEMs.
Nevertheless, Honda launched the all-electric Prologue, which has found quick success with US consumers. Shortly thereafter, Acura launched the ZDX, which sits atop the same Ultium platform as Prologue, provided through a partnership with GM.
Honda has since backed out of that partnership—at least the part where GM provides vehicle architecture—and has been developing its own in-house platform that will one day power its new 0 Series lineup of BEVs. These originally debuted at CES 2024 and remerged at this year’s event as prototypes—and now they’re white! They will also feature a new proprietary vehicle OS called ASIMO (more on that below).
While we await the arrival of those Honda BEVs, we can expect to see a new Acura model hit the market first, based on an SUV called the Performance EV Concept, which debuted at Monterey Car Week this past August. At the time, the Acura Design Studio described the concept as “the evolution of Acura’s performance-focused design direction and the brand’s next all-electric model.”
That new production model didn’t have a name yet, but we did learn it would be the first BEV to debut on Honda’s new bespoke platform and the first all-electric model to roll off its assembly lines at the new Honda EV Hub in Marysville, Ohio.
Today, we learned that the Performance EV Concept has evolved into a full-fledged passenger model with a familiar name – the Acura RSX EV.
Acura brings back the “RSX” nameplate as an EV SUV
During a media briefing earlier this week, American Honda shared its 2025 outlook, led by vice president of sales, Lance Woelfer. This year’s strategy includes the production of its first original BEV in Ohio using domestically and globally sourced parts as a new hybrid model and several ICE vehicles (boo).
Woelfer confirmed that the first bespoke all-electric model coming out of Ohio will be the Acura RSX EV. This move marks the return of a notable nameplate in the Acura lineup that evolved from the original Honda Integra. The Acura RSX was sold in North America from the early- to mid-2000s and still has a decent fanbase, especially amongst fans of the Honda Integra and Japanese Domestic Market (JDM) enthusiasts.
Acura revived the Integra nameplate in 2021 as a Honda Civic-based liftback, and although that model is sharp, it remains combustion, hence why Acura has revived the RSX name as an EV model. Per Mike Langel, assistant vice president, Acura National Sales.
The nameplate pays homage to the Acura RSX with its coupe-like silhouette, but it truly represents a forward-looking approach to fun-to-drive performance. Our second all-electric SUV will solidify our EV credentials even as its ICE stablemates, the all-new ADX, RDX, MDX, TLX and Integra continue to attract new buyers to the Acura brand.
The Acura RSX EV, seen in a unique camo wrap above, looks quite sleek, but I predict Integra and RSX purists may reject this new model out of the gate because it’s undeniably an SUV, not a sporty compact like the vehicle(s) it’s named after. This reminds me of when Ford introduced the Mustang Mach-E, and brand loyalists argued, “That’s not a Mustang.” Just like the Mach-E, the Acura RSX EV represents a new generation of performance models, no matter what you call it.
The new SUV also represents a massive step for Honda and its premium brand, as the Acura RSX EV will be the first model to utilize Honda’s new EV platform and its new ASIMO OS operating system introduced at CES 2025. At the time, Honda said ASIMO will constantly update its in-vehicle software via over-the-air (OTA) updates for both the digital UX and integrated dynamics controls that will allow the automaker to deliver “a personalized ownership experience that will enhance the joy of driving.”
Acura says the RSX EV is slotted to begin development testing in real-world conditions this week ahead of planned production in Ohio later this year. We plan to visit Honda’s EV Hub later this month, so perhaps we can capture some images of where this new SUV will be built or, better yet, look at the prototype up close.
