Tesla is going to light solar on fire
Here we go again!
AC verses DC, much like Mac verses PC, is a tale as old as time. Battles fought, but the war never won. We use both everyday depending on the use and application. Each current has its place.
Energy is a pretty hot topic these days and solar is poised to become the next great battleground for the Current War. Much like it has always been, most people spend little time thinking about electrical currents. They plug something into something else and it typically just works. EV and solar aficionados on the other hand are keenly aware of the difference.
Here is a general and very basic reminder of the difference between the two currents: Typical solar panels, by their nature, have a direct current (DC) output. Household circuits and electric utility service lines use alternating current (AC). An inverter converts DC from a solar panel into household AC. String inverters handle the current conversion for a group of panels, while micro-inverters convert the current for each individual panel. Some panel manufacturers offer micro-inverters mounted on each panels and designate them as AC panels. In general, these two configurations have similar efficiency but offer unique sets of benefits for how they are used, installed, and maintained. It is important to note that each time current is converted to AC from DC and vice verse, there are losses in efficiency.
Batteries for solar arrays are similar to the panels in the sense that they are also DC by nature. These too need an inverter to get from DC to AC. There are even some that are packaged with built-in charger/inverters and marketed as “AC batteries”.
It is widely accepted that batteries are integral to the viability of solar as sustainable energy solution. Additionally, the best place for solar arrays are at their point of use, i.e. homes, office buildings, and garages. Battery storage is the key component for bridging the gap of time between energy production and use.
In a residential application the Current War is a matter of how far DC should be carried into a home, when and where it should be converted, and how many times it needs converted.
As a challenge for manufacturers and system designers, every system configuration needs to be unique to the user’s needs and goals. Some solar manufacturers have addressed the different complexities by converting everything to AC as quickly as possible. This makes a system very easy to configure, install, and expand. Each panel has a micro-inverter that essentially ties into a household AC system directly. “AC batteries” compliment this system by also tying into the house AC system directly. The generation and storage can both be easily scaled up or down based on a user’s needs. Working with AC is considered safer than with DC, which add to the reasons for why this method is appealing. The downside comes from converting current twice between the panels and the batteries, resulting in a slight reduction in efficiency.
Ironically, Tesla is expected to make a big push for a very DC-focused system, integrating a bunch of functions and elements. Nikola Tesla might be turning in his grave. Their goal is to limit the current conversion to a single point at the most downstream point possible, immediately before entering the household AC system.
Everything but the motor and onboard charger in a Tesla vehicle uses DC. Supercharging is achieved through DC and bypassing the onboard charger. The Tesla Powerwall is DC. Solar panel output is DC. It’s pretty obvious why Tesla is growing it’s DC ecosystem.
Energy generation and storage stay on the same side of the inverter. Additionally, Tesla is expected to switch another element to the DC side; the vehicle wall charger. Removing the current conversion bottlenecks will enable the vehicle to charge directly from the DC home battery to the car’s DC battery. I like to think of it as a dam exploding and releasing it’s reservoir of electrons, turning a trickling stream into a raging river!
Speculation is also swirling around the idea of vehicle-to-grid power. This would open a whole new realm of possibilities. It’s hard to say what use Tesla will make of this technology, but it could be possible to use your Tesla vehicle battery to power your home if the grid fails, or even send energy back to grid during demand spikes.
For comparison, lets look at how an AC-focused system would compare to a DC-focused system in everyday use for a house with a Tesla vehicle from the vantage of an electron (keep in mind that these two examples hardly represent the entire spectrum):
Current Conversion Points:
AC:
- Solar panel generates DC current
- Unused mid-day Solar DC current converted to household AC at the panel
- Household AC converted to DC at the house battery as excess storage
- House battery DC converted back to household AC at night to charge your vehicle
- Household AC converted to DC in the vehicles onboard charger and sent to vehicle battery
DC:
- Solar panel generates DC current. Unused mid-day solar DC sent to house battery as excess storage. Then the same current flows from your house battery to your car battery.
Zero conversions in the DC ecosystem compared to four conversions in the AC ecosystem. No loss of efficiency. No bottlenecks. Pretty slick, right?
Yeah, I didn’t address what happens when your DC house battery is low and you draw from the grid and need an AC to DC conversion. Tesla is expected to seamlessly integrate this capability into their system. One conversion is still better than four.
Both systems will have their share of advocates, and neither of them should be seen as universally ‘wrong’. It comes down to which configuration would best suit the needs and goals of its user. One major comparison between the two systems is the number of components and the likelihood of complete system failure should one single component stop working.
With an AC system, you have a lot of conversion points, but they are fairly independent. If one fails, the rest still work and your system can still function.
With a DC system, you may have one single inverter. If it fails, your entire system fails.
With varying degrees of grid reliability or “prepper” mindfulness, the spectrum of system variations can address every need. The Tesla DC ecosystem will be best used by Tesla vehicle owners. The list of which is about to explode. Not unlike that electron dam.

Tesla unfolded its first European “folding Supercharger”
Tesla’s folding Supercharger just arrived in Europe and it changes how fast charging expands.
Tesla’s Folding Unit Supercharger has officially landed in Europe, with the company teasing a new installation in its effort for a broader rollout targeting major motorway rest stops across the European continent in Q3 2026. The arrival marks a notable shift in how Tesla is thinking about network expansion, moving from hardware performance alone to engineering the logistics chain itself.
While Tesla did not reveal the exact location for the new folding Supercharger in Europe, the photo shared on X heavily suggests that this maybe somewhere in Norway. Historically, whenever Tesla rolls out an entirely new infrastructure architecture in Europe, whether it was the original Supercharger stalls years ago or these brand-new modular V4 “Folding Units”, Norway is almost always the designated launch pad because of its unmatched EV adoption rate and supportive infrastructure
The Folding Unit, introduced in March 2026, is a factory pre-assembled V4 charging station built on an industrial hinge system mounted to a heavy-duty concrete base. The entire assembly arrives on site ready to unfold and connect. Tesla confirmed the units feature telescopic light poles specifically designed for easy transportation and fast on-site deployment, a detail that signals how carefully the logistics chain has been engineered alongside the hardware itself. The design allows 33% more stalls per delivery truck, cuts installation time roughly in half, and reduces overall deployment costs by more than 20% compared to traditional installations.
Tesla’s newest “Folding V4 Superchargers” are key to its most aggressive expansion yet
Tesla also noted telescopic light poles which provide benefits over traditional Supercharger installations that require fixed-height poles that are awkward to ship, slow to position on site, and often require separate crews and equipment to erect before charging hardware can even be staged. By engineering poles that compress for transit and extend on arrival, Tesla has removed one of the quieter bottlenecks in the physical deployment process. Every hour saved on a light pole installation is an hour redirected toward getting stalls energized. At scale, across dozens of new sites per quarter, those hours add up to a meaningful acceleration in how quickly a location goes from approved permit to serving its first customer.
Each Folding Unit pairs a single V4 power cabinet with eight charging posts. The V4 cabinet delivers up to 500 kW per stall for passenger vehicles and up to 1.2 MW for the Tesla Semi, supporting twice the stalls per cabinet at three times the power density of its predecessor. Longer cables make every new station immediately usable by non-Tesla vehicles, a priority as Tesla continues opening its network to Ford, GM, Rivian, Hyundai, Stellantis, and others.
As Teslarati reported when the Folding Unit was first unveiled, Tesla’s Gigafactory New York produced its final V3 Supercharger cabinet in March 2026 after more than seven years and 15,000 units, completing a full pivot to V4 production. The European arrival of the folding design is the next chapter in that transition.
Faster and cheaper deployment means Tesla can justify building in markets and corridors that were previously too expensive to serve, filling the coverage gaps that have slowed EV adoption outside major urban centers.

SpaceXAI just launched into your kitchen with their new app
SpaceXAI just powered its first consumer app and it predicts what you want to buy.
SpaceXAI just made its first move into consumer AI, and it involves your grocery cart. On June 3, 2026, Gopuff and SpaceXAI announced the launch of Go, a Grok-powered shopping assistant built directly into the Gopuff app that predicts what you need before you even start searching for it.
Gopuff is an instant delivery platform that operates more than 400 micro-fulfillment centers across the U.S., delivering everyday essentials, snacks, drinks, and household items in as little as 15 minutes. It is not a restaurant delivery app or a marketplace. It owns its inventory, controls its warehouses, and handles its own logistics, which means it has built one of the most detailed consumer behavior datasets in retail over its 13-year history.
Go combines SpaceXAI’s advanced reasoning, voice, and image generation models with Gopuff’s dataset of hundreds of millions of orders and real-time cultural signals from X to prepare a suggested cart the moment a customer opens the app. It learns each shopper’s habits and automatically builds a personalized cart based on time of day, location, order history, and real-time indicators. Returning customers can check out with a single tap.
Rather than searching for specific items, users can describe a situation like a game-day party or the desire for a healthy breakfast and Go will assemble a cart automatically. It can also predict when shoppers are running low on items like coffee or paper towels and have them packed and delivered in under 15 minutes. Grok voice integration lets users talk to the app in plain conversational language and check out completely hands-free.
Gopuff co-founder and co-CEO Yakir Gola said: “Today, we believe the greatest friction left in commerce is not delivery or instantaneous access to the essentials customers need. It’s the moment before: the thinking, the deciding, the remembering. We’re combining Gopuff’s demand intelligence with xAI’s frontier reasoning to create an everyday shopping experience that feels like a true extension of you.”
Why SpaceX just made a $60 billion bet on AI coding ahead of historic IPO
The timing carries context beyond the product launch. SpaceXAI was formed after SpaceX completed an all-stock merger with Elon Musk’s xAI earlier this year, folding one of the most advanced AI labs in the world into the same corporate structure as the company preparing what could be the largest IPO in history. SpaceXAI is dipping into consumer-focused AI just as it prepares for its public debut, and while Musk has openly discussed building an everything app, this launch uses Grok to power another company’s product rather than launching a standalone consumer platform. Every consumer-facing deployment of Grok ahead of the IPO roadshow adds tangible evidence that SpaceXAI is not just an infrastructure play but a direct competitor in the AI application layer where OpenAI and Google are already fighting for dominance.

Tesla saves its passengers again – This time after a 300-foot cliff fall in Malibu
A Tesla Model 3 fell 300 feet off a Malibu cliff and both passengers survived.
A Tesla Model 3 plunged roughly 300 feet off a cliff on Mulholland Highway in Malibu on Friday morning, May 29, 2026, and both occupants survived. The crash was reported at approximately 7:30 a.m. near the 2500 block of Mulholland Highway, triggering a multi-agency rescue operation involving Malibu Search and Rescue, the Los Angeles County Fire Department, the California Highway Patrol, and McCormick Ambulance.
When first responders arrived, the male driver was outside the vehicle shouting for help while the female passenger remained pinned inside the Tesla. Rescue crews rappelled down the cliffside on ropes to reach the wreckage. A flight medic was lowered by helicopter to begin treating both victims, and the driver was hoisted up to the roadway before crews used the Jaws of Life to free the trapped passenger. Both were airlifted to a local trauma center with moderate injuries despite a remarkable result for a fall that steep.
The outcome is not surprising, considering Model 3 earned an overall 5-star rating from NHTSA in every category and sub-category, and recorded the lowest probability of injury of any car ever evaluated by the U.S. New Car Assessment Program. The absence of a traditional engine in the front of the vehicle creates a longer crumple zone that absorbs impact energy before it reaches occupants, and the battery pack running along the floor gives the car an unusually low center of gravity that reinforces structural rigidity.
This is not the first time a Tesla has kept passengers alive after going off a cliff. A Tesla Model Y carrying a family of four survived a plunge off a cliff at Devil’s Slide near San Francisco in January 2023, with two adults and two children walking away from a 250-foot fall. That incident drew widespread attention to how the structural integrity of Tesla’s electric platform performs in extreme crash scenarios that most vehicles would not survive.
