For years, Tesla Powerwall has been the go-to recommendation for “normals” looking for a painless, low-effort experience from their first home solar and battery backup solutions. Its CEO’s recent involvement in controversial politics, however, means that people are now distancing themselves from the once-trailblazing company.

It begs the question: what other home solar battery solutions are there?

UPDATE 26JUL2025: added more options, put everything in alphabetical order.

Electricians and contractors often praise the sleek, energy-dense Tesla Powerwall, for good reasons. But the Powerwall isn’t the only top-shelf home battery on the market, but long wait times, Elon’s antics, and the proliferation of really good integrated alternatives from legacy EV brands might have you shopping for Tesla alternatives already. If that’s you, the next logical step is to re-think the brand’s solar battery offerings as well – here are some of the best options out there.

As I was putting this list together, I realized there were plenty of ways for me to present this information. “Best batteries ..?” Too opinion-based. “Cheapest batteries ..?” Too much research and a quick descent into Temu-grade nonsense. In the end, I went with the same solution I’ve been using on my 0% EV financing lists: alphabetical order, by brand. Enjoy!

Bluetti EP800 + B500

If you’re in a smaller space or renting and can’t (or don’t want to) add a hardwired battery solution to your home, Bluetti’s EP800 + B500 modular system is a sweet “middle ground” option that combines the Bluetti EP800 off-grid inverter and the company’s B500 battery packs in a floor-standing unit that can be used without a solar roof but also plays well with most rooftop PV options.

The basic EP800 + B500 package offers about 9.9 kWh of capacity for under $9,000 as I type this, and the system can scale up to nearly 20 kWh by adding more B500 packs. The system puts out 7.6 kW of power – more than enough, in other words, to keep some lights on and your fridge and foods (and meds) cold.

What’s more, it works great with Bluetti’s AC300 or AC500 gear if you want an option that’s a bit more portable if you move a lot or plan on moving soon.

EG4 14.3 kWh PowerPro

Two of the home solar installers I talked to in preparing this post mentioned the EG4 14.3kWh batteries, and its specs (on paper, at least) compare nicely with the Powerwall 3.

Battery Usable capacity (kWh) Continuous power output (kW) Roundtrip efficiency Average price per kWh* Coupling
Tesla Powerwall 3 13.5 11.5 97.5% $926 DC or AC
EG4 14.3kWh PowerPro 11.44 10.24 99% $786 DC

“The EG4 PowerPro solar battery from EG4 Electronics is the strongest alternative to the Tesla Powerwall,” writes Kristina Zagame, from the home solar experts at EnergySage. “(The EG4) has a similar capacity, meaning it’ll last a similar amount of time, and a slightly lower power output, which means it won’t be able to power quite as many devices at the same time. And, based on quotes through EnergySage, EG4 batteries tend to be a bit more affordable compared to Tesla.”

Enphase IQ Battery 10

If you’re looking for a one-brand solution for EV charging and whole-home battery backup but don’t want to be “locked in” to GM or Tesla’s ecosystem, Enphase offers a full line of Made-in-the-USA solutions that could be right for you.

“Energy systems developer Enphase Energy is providing an even more holistic approach to managing home power usage with the introduction of new EV charger technology called the IQ line,” wrote Scooter doll, when the brand first introduced its EV charging solutions back in 2023. “The Enphase IQ is Wi-Fi enabled and integrates seamlessly into a customer’s existing home system that can be controlled with your phone.”

Franklin WH aPower 2

If you love the sleek, minimalistic styling of the Tesla Powerwall 3 but still prefer to spend your money elsewhere, the Franklin WH aPower 2 offers similarly sleek styling and beats the Tesla offering on usable energy storage capacity by 1.5 kWh. That’s nearly a full day of keeping a modern refrigerator running.

The Franklin is also designed to be easily retrofit into an existing solar system, but it loses out to the Powerwall on price per kWh, at $1,176 (vs. $926 for the Tesla unit).

GM Energy Home System

Arguably the most fully integrated EV + battery backup + solar option out there outside of Tesla, the GM Energy Home System promises to do everything a conventional home solar battery does, plus work seamlessly with your GM EV to provide even more flexibility – whether that means using the electric fuel stored in your EV to hold out that much longer in an emergency, or using the energy stored in your home’s solar battery to power an escape in your EV is up to you.

GM Energy and GM’s car dealers list Qmerit as their installation partner, and they’re great, but if you “already have a guy,” you can order the Home System directly from GM Energy’s website for $12,700 (as I type this).

The GM Energy Home System system includes:

  • GM Energy PowerBank
  • GM Energy PowerShift Charger
  • GM Energy Home Hub & Inverter

StorEn vanadium flow BESS


StorEn Vanadium Flow Batteries

If lithium-ion’s ten-year cycle life or overhyped fire risk makes you nervous, StorEn Technologies is developing a consumer-focused battery solution based on vanadium flow chemistry. Their system promises to last 25 years or more with no capacity loss, so you can charge and drain the battery fully each day and without stressing about wear … but there are a couple of downsides.

First, they’re not yet available to the general public – only to StorEn’s early investors in (what I understand to be) a sort of quasi-Kickstarter deal.

Second, the StorEn batteries are significantly bulkier than a Powerwall. That said, if you’ve got the room and you’re old enough to realize that 25 years isn’t actually a super long time, the StorEn solution might to be a super compelling, nearly maintenance-free setup that might outlast both your solar panels and the roof they’re mounted on.


VillaGrid+ battery; via Villara.

So, remember how I started this off saying that I wouldn’t turn this into a “best batteries” post? That’s partly driven by the fact that I’m neither an electrician, a chemical engineer, or someone who’s researched thousands of end-user experience surveys to come up with whatever metrics I’d need to confidently and correctly call one battery “the best.”

Our friends and solar industry experts at EnergySage, though? They’ve got all three of those things on staff, and they really, really like the Villara VillaGrid+.

“The Villara VillaGrid+ stands out as the best battery on the market, scoring highest in EnergySage’s rigorous Equipment Rating System, explains EnergySage’s Kristina Zagame. “That said, (the Villara VillaGrid+) is not necessarily the best Tesla Powerwall alternative. It’s a very different (and much pricier) battery.”

What puts the VillaGrid+ on top? According to Zagame, it all comes down to the battery’s lithium-titanium-oxide, or LTO chemistry. “Unlike more traditional lithium-ion batteries, LTO has better recharge capabilities for longer life cycles, and doesn’t contain any carbon, which makes it extra safe. The only downside is you’ll definitely shell out more money upfront for the VillaGrid+.”

That extra money will also buy some additional peace of mind, as Villara backs its LTO batteries with a 20-year warranty compared to Tesla Powerwall and its (and just about everyone else’s) 10-year deal. I couldn’t find a price, but Villara’s other products, like VillaGrid 5.75 kWh battery, come in at nearly double Powerwall’s per kWh cost. Check out the specs, below, then let us know if you think the novel chemistry and additional warranty are worth it in the comments.

Battery Usable capacity (kWh) Continuous power output (kW) Roundtrip efficiency Average price per kWh* Coupling
Tesla Powerwall 3 13.5 11.5 97.5% $926 DC or AC
Villara VillaGrid+ 11.5 10 98.5% Get quote DC or AC

E-quipment highlight: Komatsu PC20E-6 electric mini excavator

Japanese equipment giant Komatsu has added a not-so-giant electric excavator to its growing lineup of battery-powered construction equipment. The new Komatsu PC20E-6 electric mini excavator promises a full day of work from a single charge.

Komatsu says the design of its latest mini excavator was informed by data sourced from more than 40,000 working days of comparably-sized diesel excavators. The company found that, in 90% of its global customers’ mini excavator deployments, these vehicles are in active use for less than 3.5 hours per day.

“This defined the target for the required, reliable working time with the excavator,” reads the Komatsu web copy. “This result makes it possible for Komatsu to offer an attractively priced machine with a performance that exactly matches the requirements.”

Keeping costs down are relatively conservative specs. Komatsu chose to power the PC20E-6 with a 23.2 kWh battery pack sending electrons to an 11 kW (~15 hp), high-torque electric motors. Not exactly super impressive on paper, but the machine has an operating weight of 2,190 kg and enough juice for up to four (4) hours of continuous operation.

More than enough, in other words, to have completed 90% of of those 40,000 work days the company analyzed.

Getting it done

If, for some reason, that four hours’ runtime isn’t enough, an on-board charging option for 230V and 3kW charging power compatible with various plug adapters is standard, with an external DC quick charger for 400V and 12 kW charging as optional. In either case, it won’t be long before the machine is back at work.

To help the later adopters sleep well about their battery-powered investments, the PC20E-6 ships with Komatsu’s E-Support maintenance program, which includes free scheduled maintenance by a Komatsu-trained technician, a 3 year/2,000 hour warranty on the machine, plus a 5 year/10,000 hour warranty on the electric driveline. The company says the battery should last 10 years.

“The Komatsu E-Support customer program is included free of charge with every market-ready electric mini excavator and offers exclusive machine support,” said Emanuele Viel, Group Manager Utility at Komatsu Europe. “The bottom line is that the risk for the end customer is significantly reduced, especially when it comes to exploring the electrification advances in the industry.”

Komatsu hasn’t released official pricing quite yet, but has revealed that the P20E-6 will begin series production this October.

Tesla unexpectedly ends contract at Giga Texas, letting go 82 people

Tesla unexpectedly ends contract at Giga Texas, letting go 82 people

Tesla has unexpectedly terminated a contractor’s contract at Gigafactory Texas, resulting in the layoff of 82 workers who were supporting the automaker’s production at the giant factory in Austin.

MPW Industrial Services Inc., an Ohio-based industrial service provider specializing in cleaning and facility management, has issued a new WARN notice, confirming that it will lay off 82 workers in Texas due to Tesla unexpectedly ending its contract with the company.

Here are the details from the WARN notice:

  • State / agency: Texas Workforce Commission (TWC).
  • Notice date: August 27, 2025.
  • Employees affected: 82
  • Likely effective date: September 1, 2025
  • Context from the filing/letter: layoffs tied to an unexpected termination of a major customer contract (Tesla—Gigafactory Texas, 1 Tesla Road); positions include 61 technicians, 7 team leads, 7 supervisors, 7 managers; no bumping rights; workers not union-represented.

In April 2024, Tesla initiated waves of layoffs at the plant, resulting in the dismissal of more than 2,000 employees in Austin, Texas.

Since then, Tesla’s sales have been in a steady decline. While the automaker is expected to have a strong quarter in the US in Q3 due to the end of the tax credit, sales are expected to decline further in Q4 and the first half of 2026.

Many industry watchers have expected Tesla to initiate further layoffs due to the situation.

Electrek’s Take

We may be seeing the beginnings of a new wave of layoffs at Tesla, as the automaker typically starts with contractors.

To be fair, Tesla could also potentially end the contract unexpectedly for other reasons, but the timing does align with the need to cut costs and staff ahead of an inevitable downturn in US EV sales.

I think it’s inevitable that we start seeing some layoffs. I think Tesla will have to slow down production in the US to avoid creating an oversupply, especially in Q4-Q1.

After e-bike fury, suburban pearl-clutchers set their ire on golf carts

After e-bike fury, suburban pearl-clutchers set their ire on golf carts

First, it was e-bikes, offering an efficient, effective, and low-cost way for teens and just about everyone to zip around town, yet drawing the temper of suburban traditionalists. Now golf carts are the new public enemy number one in suburbia, at least if you ask the growing number of online groups where residents complain about these small electric vehicles “clogging” their streets.

But beyond the hand-wringing, golf carts and their more sophisticated cousins known as Neighborhood Electric Vehicles (NEVs) or Low Speed Vehicles (LSVs), are quietly becoming a popular alternative to cars for short trips around US cities and suburbs.

While most people still associate golf carts with retirement communities in Florida or slow rides across 18 holes, street-legal versions have been around for the last few decades.

But these aren’t your grandpa’s bare-bones carts, complete with a golf pencil clip. Many now come with DOT seat belts, lights, turn signals, mirrors, backup cameras, and speed limiters that allow them to operate legally on roads up to 35 mph, as long as they meet all the federal requirements for Low-Speed Vehicles (LSVs).

That means such vehicles are legally allowed to operate like cars, trucks, bicycles, or motorcycles on the vast majority of residential streets and a surprising portion of urban grids. In other words, for grabbing groceries, school drop-offs, or cruising to a friend’s house, they’re a practical, cheaper, and far greener substitute for firing up a 5,000-pound SUV.

The Club Car Cru adds extra luxury to the concept of an LSV

Golf carts have been slowly taking off for years, but the pandemic accelerated the trend. Sales of golf carts and LSVs spiked as families looked for safe, outdoor transportation and an easy way to get around their neighborhoods. Now, in cities all over the country, the sight of parents driving their kids to school or running errands in a cart is increasingly common. In some towns, petitions have even popped up with hundreds of residents asking for local ordinances to legalize them on more streets, according to the Daily Mail.

Of course, not everyone is thrilled. There’s growing backlash against the increase in golf carts on streets, with many residents calling them a “plague” and complaining that they’re taking up space on the roads, in parking lots, or creating unsafe conditions. While rare, there have been serious accidents too, with a handful of tragic cases highlighting the dangers of mixing small, lightweight carts with full-size vehicles. Critics argue that carts lack the crash protection of cars and don’t always fall under homeowners’ insurance policies if an accident happens.

But for every critic, there’s a supporter pointing out that golf carts take cars off the road, save money on fuel, and are no more dangerous than scooters or e-bikes – modes of transport that already share the streets. And major golf cart makers have been happy to respond to the demand with boosted sales and new models. Companies like E-Z-GO, Club Car, WAEV, Kandi, and others are all rushing new models to the market as more suburban commuters discover that their next electric vehicle might just cost a fraction of what they thought it would – and come with a better breeze, too.

The GEM microcars are classic LSVs that have brought smiles to families’ faces for decades

Electrek’s Take

If I didn’t know any better, I’d say it’s like the Karens are just following me around to poo-poo on any alternative vehicle I happen to drive that week. They’ve hit all my favorites. Pretty soon, they’ll be coming for my electric tractors, too!

But seriously, this feels like déjà vu. The same arguments we’ve heard for years against e-bikes are now being recycled against golf carts: too unsafe, too disruptive, too “different” from the car-centric status quo.

But the reality is, again, quite the same as e-bikes. These are small electric vehicles that make a ton of sense and are totally street legal, at least when they’re built correctly to conform to the proper laws.

They come with a lot of the same benefits, too. They’re cheap to operate, easy to park, perfect for short trips, and they prevent larger cars from needlessly clogging residential streets. Will they ruffle feathers among the kind of folks who have had one too many frisbees land in their yard? Perhaps. But much like e-bikes, their popularity is only going one direction – up.

I leave you with a few images of perhaps my favorite of all, the Kandi Mini. The nay-sayers can pull it from my cold, dead, golf
