As part of Tesla software update 2024.38.4, Tesla has finally included updates to Sentry Mode to reduce its power consumption.

Sentry Mode is part of Tesla’s security system that keeps the vehicle sensors and cameras on to detect, record, and then inform the owner about suspicious activity. You can read more about it, including how much power it consumes, in our guide covering Tesla Sentry Mode.

Sentry Mode Battery Drain

Sentry Mode keeps the vehicle awake and continuously processes data from the vehicle’s eight cameras. However, due to the vehicle’s architecture and processing the multiple video feeds, Sentry Mode consumes a significant amount of power. Over a 24-hour period, an average Model 3 or Model Y will typically experience a battery drain of about 7-14% with Sentry Mode enabled, or roughly about one mile per hour.

While Sentry Mode is a great security feature, owners often have to decide whether the loss of range is worth the added security. Sentry Mode also becomes an issue when leaving your vehicle parked for an extended period of time, such as at the airport.

Sentry Mode Improvements

Tesla announced earlier this year that they were bringing significant efficiency improvements to Sentry Mode by cutting power usage by 40%.

Update 2024.38 is bringing about those changes. Tesla is changing the way its onboard computers process video to make Sentry Mode use much more efficient. Right now, the vehicle needs to keep its FSD and MCU (infotainment) computers on to process videos from the vehicle’s cameras. However, that’s changing with some architectural improvements in update 2024.38.

This change will arrive first with the Cybertruck in update 2024.38.4 and later. According to our source, it will also be available for other models in a future update, but Tesla is starting with the Cybertruck first.

Since most Cybertrucks have FSD included as part of the Foundation Series, they’re on FSD-specific updates, meaning that the number of Cybertrucks with update 2024.38 is extremely small. Once it becomes more widely available, we should be able to get some numbers to see how close Tesla got to its 40% power reduction.

Update: Read our follow-up story on the changes Tesla is making in the way it processes video to improve Sentry Mode’s power consumption.

World’s Largest Tesla Supercharger: 168 Stalls, 100% Off-Grid, Powered by Sun and Battery Storage

In just 8 months, Tesla has gone from breaking ground to delivering electrons at its most ambitious Supercharger project to date, just in time to be ready for the busy Fourth of July holiday weekend. Project Oasis, the world’s largest Supercharger site, is now partially open to customers for its first phase in Lost Hills, California.

What makes this remarkable is the speed of execution. In just eight months, Tesla has constructed a site that will eventually feature 168 stalls (84 stalls are now open), supported by 11 MW of solar power and 10 Megapacks of battery storage. That construction speed is pretty impressive, but what is even more impressive is how this new station operates and what it means for future Supercharging infrastructure.

Self-Sufficient Energy Oasis

The first 84 stalls at Lost Hills are now open, and according to the Tesla Charging team, they are currently powered solely by the sun and operate off-grid.

This makes it more than just a new Supercharger site. It serves as a proof of concept for a new type of Supercharger. Unlike nearly every other charging site in the world, which draws power from local utilities, this station generates its own clean electricity from its massive solar array and stores it in its array of on-site Megapacks. 

Self-sufficient charging stations are something completely different than what we see today. They are highly resilient since they’re not reliant on the grid. That means that even if there is a local power outage, brownout, or blackout, one can always come to Lost Hills to Supercharge.

If you’ve got a Cybertruck, you could take advantage of the Cybertruck’s Powershare feature and charge up at Lost Hills to help keep your home powered during a blackout, utilizing the Cybertruck as a portable battery charger. Now that’s true independence and self-reliance.

The Future of Charging

Solar-powered Superchargers help avoid massive new loads on already stressed electrical grids, especially during peak afternoon and evening hours, when demand is the highest.

This is Tesla’s vision for the future of charging: a clean, fully closed-loop ecosystem that sustains itself. The sun’s energy is captured, stored, and delivered directly to vehicles on site at any time of day without relying on the electrical grid or fossil fuels.

Largest Supercharger in the World

This opening of 84 stalls is just the first phase of the project. Tesla says that the remaining stalls, as well as a new on-site lounge, are coming later this year. Once complete, the 168-stall site will be the largest Supercharger site in the world.

While the speed of building such a massive project in just eight months is a testament to Tesla’s execution, the true innovation is actually that self-sustainability. Let’s hope we see even more large, self-sufficient Supercharger sites across the world in the near future.

Elon Musk Considers Solar Gigafactory in North America to Power AI Boom

By Karan Singh

Elon Musk is once again seeking to expand Tesla’s vertical integration in the energy sector, this time focusing squarely on solar power. Following discussions on X that highlighted the massive gap in solar deployments between the US and China, Elon is now discussing the need for a Tesla Solar Gigafactory in the United States.

This potential move is driven by a specific catalyst: the exponential growth of AI is creating an insatiable demand for electricity. For Tesla and xAI, two of Elon’s companies betting their future on AI, building the power generation required is a strategic necessity.

A new factory wouldn’t just be about making panels; it would be about manufacturing the final missing piece in Tesla’s vertically integrated energy ecosystem.

Catching Up to China

The context for this renewed focus is pretty stark. In May, China reportedly added a staggering 93 gigawatts (GW) of solar power capacity. In contrast, the United States installed approximately 14 GW over the entire first quarter, roughly 20 times less than China.

The primary driver of this demand is the revolution in AI. Training ever-larger and smarter AI models involves operating vast data centers, which consume staggering amounts of power. Google, Amazon, and Microsoft have turned to small-scale nuclear reactors, with Microsoft petitioning to reopen the infamous Three Mile Island for its AI operations.

For Elon’s companies, whose future products like FSD, Optimus, and Grok are built on a foundation of real-world AI, securing a massive and sustainable energy supply isn’t a side quest. It is part of the main mission, especially in conjunction with grid-scale storage, such as Megapacks and Powerwalls. You can’t power a world of autonomous robots without a world of abundant, clean energy.

The Tesla Ecosystem

A US solar gigafactory would be the final, logical step in completing Tesla’s energy hardware ecosystem. While Tesla already manufactures some solar panels and the Tesla solar roof, the scale is too minuscule to matter. 

By mass-producing its own panels, while also increasing Solar Roof production, Tesla would become a true one-stop shop for all things green energy. This would allow the company to supply its own large-scale projects, like the massive solar array for Project Oasis - the world’s largest Supercharger site.

It would also enable more complete residential packages, like the Giga-Small Haus concept home, combining Tesla-made panels and roofs with a Powerwall 3. This level of vertical integration would give Tesla complete control over the technology, cost, and supply of every major component in its energy ecosystem, from generation to storage to mobility.

Building a new Solar Gigafactory is about much more than just simply producing solar panels. It’s a requirement to power Tesla’s future products and make solar panels accessible to everyone.
