A Tesla Megapack is powering a large housing factory completely off-grid in Patterson, California, with energy from a large array of on-site, PVGraf solar panels. The factory isn’t connected to the local power grid, and this is the first time a Tesla Megapack has been deployed and running completely off-grid. The system has been operating without any issues since November.
S2A Modular, a tech company that manufactures modular homes, tiny houses, and more that run on direct-current (DC) power, owns the Tesla Megapack, and its president and cofounder, John Rowland, granted Teslarati an exclusive interview. The company is also in the business of addressing housing for the homeless as well as making luxury homes and single-family homes.
John Rowland, S2A Modular’s president, and cofounder, granted Teslarati an exclusive interview. He shared with Teslarati that the company has 35 facilities, with five currently under construction and Tesla Megapacks on order. The first one in Patterson, California, is completely off the grid, and John has been working with Tesla to monitor its progress.
The delivery and installation of the Tesla Megapack, John explained, was “very smooth.” All of the infrastructure was in place, and it only took a couple of days to install the battery.
John told Teslarati that the reason why he went with Tesla is that he is a huge fan of both Tesla and Elon Musk. Initially, he had planned to buy the Tesla PowerPacks but by the time the factory came to fruition, Tesla Megapacks were available. As a homebuilder, he wanted to build homes that run on batteries. John said that engineered and built the second off-grid Tesla-powered home in North America.
“When I built that home, I decided I wanted to scale and build homes that were meant to run on batteries because this is how that house was engineered and built. It was the lowest voltage, lowest amperage home on the planet.”

John realized that in order to scale, he would need a factory and wanted to take the same approach that he has taken to engineering and building the homes and “engineer and build a factory that was made to run off-grid.
The hundred thousand-square-foot factory has no gas, or propane, only graphene solar panels, and a Tesla Megapack. “And no connection to the electrical grid.”
John pointed out that he has had a good relationship with Tesla since 2015, and once the Megapacks were available, he ordered one for each of the facilities.
“We’ve got the first one in Patterson, California, and it’s been up and running a little over a month now. And it’s running like a champ. The whole factory’s powered off-grid, and it’s a huge success, so we’re looking to carry it over to our next facilities.”
John and his team and Tesla are monitoring the battery three times a day since it is completely off-grid. At first, there was a little hesitation on Tesla’s part for installing a completely off-grid Megapack, but John was able to win them over, and things are going smoothly.
“This is the first time that a Megapack was programmed to run off-grid. They’re set to take a trickle charge from the grid 24/7, and it took some convincing to get Tesla to allow us to do it this way. At first, they said, ‘you’re a couple of years ahead of us,’ but they finally agreed to allow us to do it, and now they’re using it as beta. They’re monitoring it just like we are.”
“One of Tesla’s head engineers that we work with told us that when we powered it up, it would take four days for our solar to charge the battery fully. We did it in seven and a half hours.”
John explained that the solar panels his company uses are made with specially manufactured graphene solar panels. “They’re the only company in the world using graphene, and they have 20 worldwide patents on it. At S2A, we paid and file our own UL( Underwriter Labs) to have our own UL-rated panel produced.”
When asked about feedback, John explained that he talks to Tesla’s engineers regularly and provides updates on the battery’s performance.
“It’s quite to our surprise It’s a 1.4-megawatt battery, and we’re able to keep it about 90% even with all of our equipment running. It’s really working better than our expectations.”
One thing John wasn’t expecting was the surplus of energy. He actually plans to connect the Megapack to the grid next year so that he can discharge the excess power and help take some of the burdens away from the local grid.
“Our inverters are shutting off every day because we’re producing more power than we can use. Our factory is actually net-positive, and we will start contributing back to the grid next year.”
“We’ve got the battery set right now–when it reaches 97% capacity, the inverter shuts down and stops producing power. We’ve been monitoring it three times a day, and it’s been shutting off every day. Even with the factory running at full speed, we still produce excess energy.”
John added that he also purchased the Tesla Semi and plans to use them to deliver homes to customers.

Tesla launches Full Self-Driving in a new region
Today, Tesla launched Full Self-Driving in Australia for purchase by car buyers for $10,100, according to Aussie automotive blog Man of Many, which tried out the suite earlier this week.

Tesla has launched its Full Self-Driving suite in a new region, marking a significant step in the company’s progress to expand its driver assistance suite on a global scale.
It is also the first time Tesla has launched FSD in a right-hand-drive market.
Today, Tesla launched Full Self-Driving in Australia for purchase by car buyers for $10,100, according to Aussie automotive blog Man of Many, which tried out the suite earlier this week.
Previously, Basic and Enhanced Autopilot suites were available, but the FSD capability now adds Traffic Light and Stop Sign Control, along with all the features of the previous two Autopilot suites.

It is the first time Tesla has launched the suite by name in a region outside of North America. In China, Tesla has “City Autopilot,” as it was not permitted to use the Full Self-Driving label for regulatory reasons.
However, Tesla still lists Full Self-Driving (Supervised) as available in the U.S., Canada, China, Mexico, and Puerto Rico.
The company teased the launch of the suite in Australia earlier this week, and it appeared to have been released to select media members in the region earlier this week:

The rollout of Full Self-Driving in the Australian market will occur in stages, as Model 3 and Model Y vehicles with Hardware 4 will receive the first batch of FSD rollouts in the region.
TechAU also reported that “the initial deployment of FSDs in Australia will roll out to a select number of people outside the company, these people are being invited into Tesla’s Early Access Program.”
Additionally, the company reportedly said it is “very close” to unlocking FSD in customer cars:

Each new Tesla sold will also come with a 30-day free trial of the suite.
Australia is the sixth country to officially have Full Self-Driving available to them, following the United States, Canada, China, Mexico, and Puerto Rico.
Here’s the first look at the suite operating in Australia:

Tesla AI6 chips will start sample production at surprising Samsung site
AI6 is expected to be used in Tesla’s expanding lineup of high-volume products, such as the Cybercab and Optimus.

It appears that the initial sample production of Tesla’s next-generation AI6 chip would not start in Samsung’s United States-based facilities.
AI6 is expected to be used in Tesla’s expanding lineup of high-volume products, such as the Cybercab and Optimus.
Early AI6 production
As noted in a ZDNet Korea report, the production of initial samples of Tesla’s AI6 chip is expected to start at Samsung Electronics’ domestic foundry and packing facilities in South Korea. Mass production for AI6 chips will follow at the tech giant’s Texas-based foundry in Taylor, which is expected to start operations in 2025. Investment in mass production facilities for the Taylor plant are expected to start this year, the publication noted.
Samsung has reportedly finalized the process design kit for its second-generation 2nm technology. This node offers a 12% performance improvement, 25% lower power consumption, and an 8% reduction in chip area compared to its previous-generation counterparts.
Tesla’s AI6 deal
As per previous reports, Tesla has signed a $16.5 billion contract with Samsung for the production of its AI6 chips. In a post on social media platform X, Musk clarified that $16.5 billion is actually just the bare minimum. Considering that the demand for AI6 chips will be substantial due to the ramp of products such as Optimus and the Cybercab, it would not be farfetched if the deal becomes notably larger in the future.
Musk has shared his excitement for Samsung’s production of AI6 chips, with the CEO stating on X that he would “walk the line personally” in the facility to “accelerate the pace of progress.” In a follow-up comment, the Tesla CEO stated that Samsung is fully aware of what a real partnership with Tesla will be like. “I had a video call with the chairman and senior leadership of Samsung to go over what a real partnership would be like. Use the strengths of both companies to achieve a great outcome,” Musk wrote in his post.

Elon Musk’s Boring Company begins Tesla FSD testing in Las Vegas tunnels
The update was shared by Las Vegas Convention and Visitors Authority (LVCVA) CEO Steve Hill.

The Boring Company has started testing Tesla’s Full Self-Driving (Supervised) system in its Las Vegas tunnels.
The update was shared by Las Vegas Convention and Visitors Authority (LVCVA) CEO Steve Hill in a comment to Fortune.
Controlled FSD testing
In his comments, Hill noted that Tesla’s FSD tests in the Boring Company’s underground tunnels in Las Vegas have been going on for months. However, the full-self driving Teslas have reportedly not been carrying passengers during the tests. Interestingly enough, Hill noted that the FSD-driven vehicles have not had any incidents in the Boring Company tunnels yet, though safety drivers have been required to intervene “periodically.”
Hill further noted that the self-driving Teslas have found some spots that seem quite difficult in the underground tunnels system. The LVCVA CEO added that the rock walls of the Boring Company tunnels and their colorful lighting have created some “interesting but odd lighting” for FSD. That being said, Hill noted that the FSD tests are ongoing, though the LVCVA will likely be a consultant before the self-driving vehicles’ safety drivers are removed.
The executive, however, noted that it will only be a matter of time before the Teslas in Las Vegas’ Boring Company tunnels are operating without a driver. “Sooner or later, this is going to be autonomous,” Hill said.
Vegas Loop updates
The Boring Company’s underground transit system has been operating beneath the Las Vegas Convention Center for about four years. While the network is slated for expansion across more of the city, it currently connects the convention grounds with a handful of nearby hotels. Updates from the Boring Company’s official social media account on X suggests that tunneling is underway across other stops in Las Vegas.
As per the Boring Company on its official website, the greater Vegas Loop, when completed, will have 104 stations across 68 miles of tunnels. This should allow the underground system to serve an estimated 90,000 passengers per hour. It will also be able to connect key locations across the city, such as Harry Reid International Airport, Allegiant Stadium, and downtown.
While the Vegas Loop is nowhere near complete, Hill noted that the system is already well appreciated by residents and visitors. As per the LVCVA CEO, the underground transport system is the “highest rated feature we have” at the Convention Center. “People love it,” he said, adding that the only reason the tunnels are not coming faster is due to holdups with permits. “We’re holding them back. They’re not holding us back,” he stated.
