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 to offer Full Self-Driving gifting program: here’s how it will work
Tesla executive Raj Jegannathan said the company would be shipping the gifting program out before the holidays, making a great gift for owners just in time for Christmas.
Tesla will soon offer a gifting program for its Full Self-Driving (Supervised) suite, allowing people to gift a subscription to the semi-autonomous driving software for a variety of timeframes.
The idea would allow people to gift Full Self-Driving as a trial, potentially shifting them to subscribe or even buy the software outright if they find it useful.
Tesla is overhauling its Full Self-Driving subscription for easier access
FSD is a pretty difficult thing to not use once you have it, and while you still have to pay attention, and it has its shortcomings, it takes a lot of the stressors out of driving.
Tesla executive Raj Jegannathan said the company would be shipping the gifting program out before the holidays, making a great gift for owners just in time for Christmas.
Will have it ready before holidays!

Full Self-Driving is Tesla’s semi-autonomous driving platform that is currently among the most robust options on the market. As a personal user, I find it to be an extremely beneficial feature that I use on a daily basis.
While Tesla does offer gift cards, this would be a great option to choose the present you’re giving to a family member or friend.
Tesla offers a subscription to Full Self-Driving in the United States for $99 per month; it gives people an opportunity to try the suite for a month and is more affordable in the short term for those who cannot swing the current $8,000 fee to purchase it outright.
CEO Elon Musk has advised every Tesla owner to purchase the suite outright. In 2020, he confirmed that a subscription program would be released, but he said, “It will be economically better to have bought FSD.”
He continued in 2021, stating that “buying FSD will still be a better long-term deal than subscription.
He has also said that the monthly subscription price could rise as FSD goes to wide release, but that has yet to happen. In fact, it was originally $199 a month, but Tesla decreased the price to $99. We’re hopeful it doesn’t get more expensive.

Elon Musk just roasted Sam Altman’s Tesla Roadster cancellation
“And you forgot to mention act 4, where this issue was fixed and you received a refund within 24 hours.
But that is in your nature.”
Elon Musk has responded to OpenAI CEO Sam Altman’s decision to cancel his Tesla Roadster reservation, which he revealed on X on Thursday.
We reported on Altman’s decision, which he called “A tale in three acts,” showing his confirmation email from Tesla back in 2018, an email requesting his $50,000 deposit back after canceling his order, and a notification from Google that the email he sent was not delivered.

Musk did not take too kindly to the post from his tech rival, first referencing his position with OpenAI, and then confirming that Altman received his reservation deposit back within 24 hours:
And you forgot to mention act 4, where this issue was fixed and you received a refund within 24 hours.
But that is in your nature.
— Elon Musk (@elonmusk) November 1, 2025
OpenAI was started by Musk, Altman, and others back in 2015, and was geared toward being a non-profit company that would develop safe artificial intelligence that would be accessible to people.
However, Musk and Altman did not agree on the future of the company. Musk left, and Altman turned OpenAI into a for-profit company. This led to a variety of lawsuits and some very public spats between the two. Musk has called out Altman for turning the company into a for-profit, which has been his main source of criticism for his former colleague.
The Roadster has been hanging in the balance of Tesla’s manufacturing plans for seven years, but the company has made more indications that it will be unveiled later this year and will have some insane technologies.
Musk said on Friday in an episode of the Joe Rogan Experience Podcast that Tesla is “getting close to demonstrating the prototype.”
He said:
“Whether it’s good or bad, it will be unforgettable. My friend Peter Thiel once reflected that the future was supposed to have flying cars, but we don’t have flying cars. I think if Peter wants a flying car, he should be able to buy one…I think it has a shot at being the most memorable product unveil ever. [It will be unveiled] hopefully before the end of the year. You know, we need to make sure that it works. This is some crazy technology in this car. Let’s just put it this way: if you took all the James Bond cars and combined them, it’s crazier than that.”
Musk hinted that the vehicle could fly and would have “crazy technology” that would put James Bond’s vehicles to shame. It will be interesting to see what Tesla will unveil when the event happens and if it can come through on this mind-blowing teaser.
