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.

EV fans urge Tesla to acquire Unplugged Performance for edge in fleet and security industry

Unplugged Performance has built a name for itself by producing performance upgrades for Tesla vehicles.

A growing number of Tesla enthusiasts and longtime community voices are calling on the electric vehicle maker to acquire Unplugged Performance, a California-based aftermarket company best known for tuning Tesla vehicles and developing specialized government fleet solutions under its UP.FIT division.

The idea was once considered a niche proposal among EV fans, but it is now gaining serious attention not just as a performance play but as a strategic move to deepen Tesla’s roots in the fleet and security industry. 

A strategic fit

Unplugged Performance has built a name for itself by producing performance upgrades for Tesla vehicles, from track-optimized components to visual and aerodynamic upgrades. But in recent years, its UP.FIT division has pivoted toward a more functional future by outfitting Tesla vehicles like Model Ys for police, military, and government use.

That work has sparked growing calls for closer collaboration with Tesla, especially as the EV maker increasingly leans into autonomy, AI, and fleet services as core components of its next chapter.

“I posted this four years ago, but I think it’s more true now than ever,” wrote Whole Mars Catalog, a well-known Tesla investor and FSD Beta tester, on X. “Tesla should buy Unplugged. But not just as a Performance division. What they are doing with UP.FIT unlocks large government and commercial fleet purchases that can improve utilization.”

Tesla fans such as shareholder Sawyer Merritt echoed the sentiment, calling Unplugged a “great fit within Tesla.” adding, “They are literally located directly next to Tesla’s design studio in Hawthorne.”

Enabling the next wave

Supporters of the idea noted that integrating Unplugged into Tesla’s corporate structure could help accelerate the adoption of autonomous technologies in government sectors. With UP.FIT patrol cars already in use across some U.S. police departments, Tesla fans envisioned a future where self-driving Teslas could potentially revolutionize law enforcement, search-and-rescue, and public service logistics.

“Just imagine how autonomous patrol cars could transform policing and bring us into a safer future,” the veteran FSD tester wrote.

The benefits could also extend to Tesla’s existing consumer base. “They also have some incredible products in the works that I think will appeal to many ordinary Tesla drivers — not just those looking for performance or mods. Stuff that’s so good it should have come straight from the design studio next door,” Whole Mars Catalog noted.

Unplugged Performance, founded in 2013, shares not just a product vision with Tesla, but also geography. Its Hawthorne headquarters sits directly adjacent to Tesla’s design studio, and the two companies have maintained a close working relationship over the years. The aftermarket firm has long positioned itself as a “mission-aligned” partner to Tesla.

In response to the recent calls for acquisition, Unplugged Performance acknowledged the support from the community. “Our very existence is to support the Tesla mission with @UpfitTesla and @UnpluggedTesla,” Unplugged CEO Ben Schaffer posted on X. “We love working with Tesla and are grateful for the community’s support since 2013!”

X account with 184 followers inadvertently saves US space program amid Musk-Trump row

Needless to say, the X user has far more than 184 followers today after his level-headed feat.

An X user with 184 followers has become the unlikely hero of the United States’ space program by effectively de-escalating a row between SpaceX CEO Elon Musk and President Donald Trump on social media.

Needless to say, the X user has far more than 184 followers today after his level-headed feat.

A Near Fall

During Elon Musk and Donald Trump’s fallout last week, the U.S. President stated in a post on Truth Social that a good way for the United States government to save money would be to terminate subsidies and contracts from the CEO’s companies. Musk responded to Trump’s post by stating that SpaceX will start decommissioning its Dragon spacecraft immediately. 

Musk’s comment was received with shock among the space community, partly because the U.S. space program is currently reliant on SpaceX to send supplies and astronauts to the International Space Station (ISS). Without Dragon, the United States will likely have to utilize Russia’s Soyuz for the same services—at a significantly higher price.

X User to the Rescue

It was evident among X users that Musk’s comments about Dragon being decommissioned were posted while emotions were high. It was then no surprise that an X account with 184 followers, @Fab25june, commented on Musk’s post, urging the CEO to rethink his decision. “This is a shame this back and forth. You are both better than this. Cool off and take a step back for a couple days,” the X user wrote in a reply.

Much to the social media platform’s surprise, Musk responded to the user. Even more surprising, the CEO stated that SpaceX would not be decommissioning Dragon after all. “Good advice. Ok, we won’t decommission Dragon,” Musk wrote in a post on X.

Not Planned, But Welcomed

The X user’s comment and Musk’s response were received extremely well by social media users, many of whom noted that @Fab25june’s X comment effectively saved the U.S. space program. In a follow-up comment, the X user, who has over 9,100 followers as of writing, stated that he did not really plan on being a mediator between Musk and Trump. 

“Elon Musk replied to me. Somehow, I became the accidental peace broker between two billionaires. I didn’t plan this. I was just being me. Two great minds can do wonders. Sometimes, all it takes is a breather. Grateful for every like, DM, and new follow. Life’s weird. The internet’s weirder. Let’s ride. (Manifesting peace… and maybe a Model Y.)” the X user wrote.

There comes a time in a driver’s life when one is faced with one’s limitations. For the driver of a Dodge Charger, this time came when he lost control and crashed into a Tesla Cybertruck–an absolute epic fail. 

A video of the rather unfortunate incident was shared on the r/TeslaLounge subreddit.

Charging Charger Fails

As could be seen in the video, which was posted on the subreddit by Model Y owner u/Hammer_of_something, a group of teens in a Dodge Charger decided to do some burnouts at a Tesla Supercharger. Unfortunately, the driver of the Charger failed in his burnout or donut attempt, resulting in the mopar sedan going over a curb and bumping a charging Cybertruck.

Ironically, the Dodge Charger seemed to have been parked at a Supercharger stall before its driver decided to perform the failed stunt. This suggests that the vehicle was likely ICE-ing a charging stall before it had its epic fail moment. Amusingly enough, the subreddit member noted that the Cybertruck did not seem like it took any damage at all despite its bump. The Charger, however, seemed like it ran into some trouble after crashing into the truck.

Alleged Aftermath

As per the the r/TeslaLounge subreddit member, the Cybertruck owner came rushing out to his vehicle after the Dodge Charger crashed into it. The Model Y owner then sent over the full video of the incident, which clearly showed the Charger attempting a burnout, failing, and bumping into the Cybertruck. The Cybertruck owner likely appreciated the video, in part because it showed the driver of the Dodge Charger absolutely freaking out after the incident.

The Cybertruck is not an impregnable vehicle, but it can take bumps pretty well thanks to its thick stainless steel body. Based on this video, it appears that the Cybertruck can even take bumps from a charging Charger, all while chilling and charging at a Supercharger. As for the teens in the Dodge, they likely had to provide a long explanation to authorities after the incident, since the cops were called to the location.
