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 has left a single loophole to purchase Full Self-Driving outright. On Sunday, the option officially disappeared from the Online Design Studio in the United States, as Tesla transitioned to a Subscription-only purchasing plan for the FSD suite.
However, there is still one way to get the Full Self-Driving suite in an outright manner, which would not require the vehicle owner to pay monthly for the driver assistance program — but you have to buy a Model S or Model X.
Months ago, Tesla launched a special “Luxe Package” for the Model S and Model X, which included Full Self-Driving for the life of the vehicle, as well as free Supercharging at over 75,000 locations, as well as free Premium Connectivity, and a Four-Year Premium Service package, which includes wheel and tire protection, windshiel protection, and recommended maintenance.
🚨 Tesla increased the price of both the Model S and Model X by $10,000, but both vehicles now include the “Luxe Package,” which includes:
-Full Self-Driving
-Four years of included maintenance, tire and wheel repairs, and windshield repairs/replacements
-Free lifetime… pic.twitter.com/LKv7rXruml— TESLARATI (@Teslarati) August 16, 2025
It would also be available through the purchase of a Cyberbeast, the top trim of the Cybertruck lineup.
This small loophole would allow owners to avoid the monthly payment, but there have been some changes in the fine print of the program, as Tesla has added that it will not be transferable to subsequent vehicle owners or to another vehicle.
This goes for the FSD and the Supercharging offers that come with the Luxe Package.
For now, Tesla still has the Full Self-Driving subscription priced at $99 per month. However, that price is expected to increase over the course of some time, especially as its capabilities improve. Tesla seems to be nearing Unsupervised FSD based on Musk’s estimates for the Cybercab program.
There is the potential that Tesla offers both Unsupervised and Supervised FSD for varying prices, but this is not confirmed.
In other countries, Tesla has pushed back the deadline to purchase the suite outright, as in Australia, it has been adjusted to March 31.

Tesla Sweden’s port deal sparks political clash in Trelleborg
The extension of Tesla’s lease has drawn criticism from the local Social Democratic opposition.
Tesla Sweden’s lease agreement at the Port of Trelleborg has triggered a political dispute, with local leaders divided over whether the municipally owned port should continue renting space to the electric vehicle maker amidst its ongoing conflict with the IF Metall union.
Tesla Sweden’s recently extended contract with the Port of Trelleborg has triggered calls for greater political oversight of future agreements.
Tesla has used the Port of Trelleborg to import vehicles into Sweden amid a blockade by the Transport Workers’ Union, as noted in a report from Dagens Arbete (DA). By routing cars via trucks on passenger ferries, the company has maintained deliveries despite the labor dispute. Vehicles have also been stored and prepared in facilities leased from the municipal port company.
The extension of Tesla’s lease has drawn criticism from the local Social Democratic opposition. Initially, the Port of Trelleborg hinted that it would not enter into new agreements with Tesla, but it eventually opted to renew its existing contract with the EV maker anyway.
Lennart Höckert, an opposition councilor, described the port’s decision as a “betrayal of the Swedish model,” arguing that a municipally owned entity should not appear to side with one party in an active labor dispute.
“If you want to protect the Swedish model, you shouldn’t get involved in a conflict and help one of the parties. When you as a company do this, it means that you are actually taking a position and making things worse in an already ongoing conflict,” Höckert said.
He added that the party now wants politicians to review and approve future rental agreements involving municipal properties at the port.
The proposal has been sharply criticized by Mathias Andersson of the Sweden Democrats, who chairs the municipal board. In comments to local media, Andersson described the Social Democrats’ approach as “Kim Jong Un-style,” arguing that political leaders should not micromanage a company governed by its own board.
“I believe that the port should be run like any other business,” Andersson said. He also noted that operational decisions fall under the authority of the Port of Trelleborg’s board instead of elected officials.

Elon Musk’s X sees outage on Monday as users report issues
Monday’s outage follows a similar issue that befell the social media platform in mid-January.
X experienced an outage on Monday morning, with tens of thousands of users reporting that the platform failed to load across both desktop and mobile. The disruption began around 8:02 a.m. ET, as per Downdetector data, and quickly escalated in the U.S. and U.K.
Monday’s outage follows a similar issue that befell the social media platform in mid-January.
Shortly after 8 a.m. ET, Downdetector showed a sharp rise in incident reports. At one point, U.S. complaints exceeded 40,000, while U.K. reports climbed past 6,000. Earlier in the outage, filings had already crossed 11,000 in the U.S. and 3,300 in the U.K., as noted in a TechRadar report. X users in other locations, such as the Philippines and Costa Rica, also reported similar issues.
Users attempting to access X were met with a “something went wrong” message. Feeds did not refresh, posts failed to appear, and both the social media platform’s app and web versions appeared affected by the issue. The outage struck during peak weekday usage, amplifying its visibility across regions worldwide.
X has not issued an official explanation for the latest outage or confirmed what caused the service disruption. The scale of complaints drew comparisons to the platform’s major outage in November 2025, which resulted in users being met with “Internal server error / Error code 500” messages, as well as Cloudflare-related error notices.
The incident also comes just weeks after X experienced a similar downtime in mid-January. That outage seemed more notable, however, with more than 100,000 users reporting issues with the social media platform on Downdetector.
