For years, Tesla Powerwall has been the go-to advice for “normals” in search of a painless, low-effort expertise from their first dwelling photo voltaic and battery backup options. Its CEO’s latest involvement in controversial politicsnevertheless, implies that individuals at the moment are distancing themselves from the once-trailblazing firm.
It begs the query: what different dwelling photo voltaic battery options are there?
UPDATE 26JUL2025: added extra choices, put every little thing in alphabetical order.
Electricians and contractors usually reward the smooth, energy-dense Tesla Powerwall, for good causes. However the Powerwall isn’t the one top-shelf dwelling battery in the marketplace, however lengthy wait instances, Elon’s antics, and the proliferation of actually good built-in alternate options from legacy EV manufacturers may need you purchasing for Tesla alternate options already. If that’s you, the subsequent logical step is to re-think the model’s photo voltaic battery choices as nicely – listed below are a few of the finest choices on the market.
As I used to be placing this listing collectively, I noticed there have been loads of methods for me to current this data. “Finest batteries ..?” Too opinion-based. “Least expensive batteries ..?” An excessive amount of analysis and a fast descent into Temu-grade nonsense. Ultimately, I went with the identical answer I’ve been utilizing on my 0% EV financing lists: alphabetical order, by model. Take pleasure in!
BLUETTI EP800 + B500
When you’re in a smaller house or renting and might’t (or don’t need to) add a hardwired battery answer to your own home, Bluetti’s EP800 + B500 modular system is a candy “center floor” choice that mixes the Bluetti EP800 off-grid inverter and the corporate’s B500 battery packs in a floor-standing unit that can be utilized with out a photo voltaic roof but additionally performs nicely with most rooftop PV choices.
The essential EP800 + B500 bundle affords about 9.9 kWh of capability for below $9,000 as I sort thisand the system can scale as much as practically 20 kWh by including extra B500 packs. The system places out 7.6 kW of energy – greater than sufficient, in different phrases, to maintain some lights on and your fridge and meals (and meds) chilly.
What’s extra, it really works nice with Bluetti’s AC300 or AC500 gear if you would like an choice that’s a bit extra moveable should you transfer lots or plan on shifting quickly.
EG4 14.3 kWh PowerPro
Two of the house photo voltaic installers I talked to in getting ready this put up talked about the EG4 14.3kWh batteries, and its specs (on paper, at the least) examine properly with the Powerwall 3.
| Battery | Usable capability (kWh) | Steady energy output (kW) | Roundtrip effectivity | Common worth 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 photo voltaic battery from EG4 Electronics is the strongest different to the Tesla Powerwall,” writes Kristina Zagame, from the house photo voltaic specialists at EnergySage. “(The EG4) has the same capability, which means it’ll final the same period of time, and a barely decrease energy output, which suggests it received’t have the ability to energy fairly as many gadgets on the similar time. And, based mostly on quotes via EnergySage, EG4 batteries are usually a bit extra reasonably priced in comparison with Tesla.”
Enphase IQ Battery 10
When you’re in search of a one-brand answer for EV charging and whole-home battery backup however don’t need to be “locked in” to GM or Tesla’s ecosystem, Enphase affords a full line of Made-in-the-USA options that could possibly be best for you.
“Power methods developer Enphase Power is offering an much more holistic strategy to managing dwelling energy utilization with the introduction of latest EV charger expertise known as the IQ line,” wrote Scooter doll, when the model first launched its EV charging options again in 2023. “The Enphase IQ is Wi-Fi enabled and integrates seamlessly right into a buyer’s current dwelling system that may be managed together with your cellphone.”
Franklin WH aPower 2
When you love the smooth, minimalistic styling of the Tesla Powerwall 3 however nonetheless choose to spend your cash elsewhere, the Franklin WH aPower 2 affords equally smooth styling and beats the Tesla providing on usable power storage capability by 1.5 kWh. That’s practically a full day of holding a contemporary fridge operating.
The Franklin can also be designed to be simply retrofit into an current photo voltaic system, nevertheless it loses out to the Powerwall on worth per kWh, at $1,176 (vs. $926 for the Tesla unit).
GM Power House System
Arguably probably the most totally built-in EV + battery backup + photo voltaic choice on the market exterior of Tesla, the GM Power House System guarantees to do every little thing a traditional dwelling photo voltaic battery doesplus work seamlessly together with your GM EV to supply even extra flexibility – whether or not which means utilizing the electrical gasoline saved in your EV to carry out that for much longer in an emergency, or utilizing the power saved in your house’s photo voltaic battery to energy an escape in your EV is as much as you.
GM Power and GM’s automobile sellers listing Qmerit as their set up accomplice, and so they’re nice, however should you “have already got a man,” you possibly can order the House System straight from GM Power’s web site for $12,700 (as I sort this).
The GM Power House System system consists of:
- GM Power PowerBank
- GM Power PowerShift Charger
- GM Power House Hub & Inverter
StorEn vanadium move BESS
If lithium-ion’s ten-year cycle life or overhyped fireplace danger makes you nervous, StorEn Applied sciences is creating a consumer-focused battery answer based mostly on vanadium move chemistry. Their system guarantees to final 25 years or extra with no capability loss, so you possibly can cost and drain the battery totally every day and with out stressing about put on … however there are a few downsides.
First, they’re not but obtainable to most of the people – solely to StorEn’s early traders in (what I perceive to be) a type of quasi-Kickstarter deal.
Second, the StorEn batteries are considerably bulkier than a Powerwall. That mentioned, should you’ve acquired the room and also you’re sufficiently old to comprehend that 25 years isn’t truly an excellent very long time, the StorEn answer would possibly to be an excellent compelling, practically maintenance-free setup which may outlast each your photo voltaic panels and the roof they’re mounted on.
So, bear in mind how I began this off saying that I wouldn’t flip this right into a “finest batteries” put up? That’s partly pushed by the truth that I’m neither an electrician, a chemical engineer, or somebody who’s researched hundreds of end-user expertise surveys to give you no matter metrics I’d must confidently and accurately name one battery “the very best.”
Our pals and photo voltaic trade specialists at EnergySage, although? They’ve acquired all three of these issues on employees, and so they actually, actually just like the Villara VillaGrid+.
“The Villara VillaGrid+ stands out as the very best battery in the marketplace, scoring highest in EnergySage’s rigorous Tools Score System, explains EnergySage’s Kristina Zagame. “That mentioned, (the Villara VillaGrid+) is just not essentially the very best Tesla Powerwall different. It’s a really totally different (and far pricier) battery.”
What places the VillaGrid+ on high? In keeping with Zagame, all of it comes right down to the battery’s lithium-titanium-oxide, or LTO chemistry. “Not like extra conventional lithium-ion batteries, LTO has higher recharge capabilities for longer life cycles, and doesn’t include any carbon, which makes it further protected. The one draw back is you’ll undoubtedly shell out extra money upfront for the VillaGrid+.”
That extra cash will even purchase some further peace of thoughts, as Villara backs its LTO batteries with a 20-year guarantee in comparison with Tesla Powerwall and its (and nearly everybody else’s) 10-year deal. I couldn’t discover a worth, however Villara’s different merchandise, like VillaGrid 5.75 kWh battery, are available in at practically double Powerwall’s per kWh price. Take a look at the specs, under, then tell us should you assume the novel chemistry and extra guarantee are value it within the feedback.
| Battery | Usable capability (kWh) | Steady energy output (kW) | Roundtrip effectivity | Common worth 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 |
