How we chose the best solar generators
As an avid outdoorsman, I’ve had the opportunity to test an extremely wide range of outdoor gear, including mobile and off-grid electrification equipment like solar-powered generators, as well as inverter and dual-fuel generators. These became particularly essential when the pandemic forced my travels to become domestic rather than international, which prompted me to outfit a van for long-term road-tripping.
To bring my work along for the ride, I needed a constant power source to charge my laptop, a portable fridge, lighting, and a myriad of devices and tools … even ebikes. As a result, I’ve tried all the leading portable power stations (and plenty that aren’t leading, too), so I know precisely what separates the best from the blah. I’ve written all about it (and other outdoor tech) for publications, including the Daily Beast, Thrillist, the Manual, and more. There were cases when my own opinion resulted in a tie, and I, therefore, looked to reviews from actual customers to determine which solar generators delivered the most satisfaction to the most users.
The best solar generators: Reviews Recommendations
The solar generators on this list span a wide range of budgets, from a few hundred dollars to a few thousand. They span several use cases, from camping to a backup for your home. Only you know all the factors that make one of these the best solar generator for you, but we think that one of these will get the job done.
Best overall: Jackery Explorer 2000 Pro
Buy it used or refurbished: eBay
Why it made the cut: This Jackery solar generator delivers the best blend of capacity, input/output capability, portability, and durability.
- Storage capacity: 2,160Wh
- Input capacity: 1,200W
- Output capacity: 2,200W (4,400W surge)
- Dimensions: 15.1 x 10.5 x 12.1 inches
- Weight: 43 lbs
- Price: 2,498
- Fast charging and outstanding capacity
- Durable and easy to use
- Plenty of ports
- Can connect to six 200W solar panels
The biggest portable power station from Jackery, a leading solar generator manufacturer, the Explorer 2000 Pro offers a tremendous 2,160 watt-hours of power, making it capable of charging a full camping setup for a few days. When plugged into six 200W solar panels, an upgrade over the four-panel setup available on the Jackery Explorer 1500, you can fully charge this portable power station in just 2-2.5 hours. That’s less than half the time of the smaller model.
On top of all that, it’s extremely user-friendly. Numerous output ports ensure that you can plug in a wide range of devices and electrical equipment. Its functions are highly intuitive, and the digital display is easy to understand. Like other Jackery generators, it’s incredibly durable, too. The one potential downside is its weight: At 43 pounds, it’s a bit heavy for its size. Even so, for all the power you can store, and the Rapid-charging time, the Jackery Explorer 2000 Pro will keep the lights on wherever you need power.

Best high-capacity: Jackery Explorer 3000 Pro
- Ample power storage for long trips or outages
- Sturdy handles and wheels make it easy to move
- Smooth design makes it easy to load and unload
- High peak output for power-intensive tasks
- Lots of ports for connectivity
This is the big sibling to our best overall pick. Inside the Jackery Explorer 3000 Pro, you’ll find 3,024Wh of power storage, which is enough to power even large devices for extended periods of time. It can charge a high-end smartphone more than 100 times on a single charge. It can also power full-on appliances in an RV or emergency situation.
Despite its large capacity, we learned firsthand that the Jackery Explorer 3000 Pro is relatively easy to move around. Sturdy handles molded into its case make it easy to pick up, while an extending handle and wheels make it easy to roll around at the campsite or any other location.
It can charge in less than three hours from a standard outlet or, under optimal conditions with the 200W solar panels, it can fill up as quickly as eight hours. That full solar array can get large and unwieldy, but a smaller setup can still provide ample charging if you don’t need to max out the capacity daily.
This portable power station offers the best of everything we loved about the Explorer 2000 Pro, there’s just more of it. When you’re living the van life, powering an RV, or trying to ride out a power outage, more is definitely better if you can justify the extra cost.
Best for frequent use: Anker 767 Portable Power Station Solar Generator
Why it made the cut: High capacity and fast charging make this long-lasting battery a solid everyday driver.
- Charges up to 80% in less than two hours
- Solid output and storage capacity
- Optional battery pack doubles capacity
- LiFePO4 batteries survive more charge cycles than traditional models
- Plenty of ports
- Built-in handle and wheels for transport
Anker has equipped its massive portable power station with LiFePO4 batteries, which stand up much better to repeat charging and discharging over the long term than common lithium-ion cells. Anker claims it can charge and discharge up to 3,000 times before it reaches 80% battery health compared to 500 in a similar lithium-ion setup. While I haven’t had the chance to run it through 3,000 cycles, LiFePO4 batteries have a well-earned reputation for longevity.
Regarding overall performance, the Anker 767 does everything you’d want a unit with these specs to do. The bad weather has given me [Executive Gear Editor Stan Horaczek] ample chances, unfortunately, to test it in real-world situations.
The built-in battery offers a 2048Wh capacity and pumps out up to 2,400W. It does so through four standard AC outlets, an RV outlet, two 120W car outlets, two 12W USB-A ports, and three 100W USB-C ports.
I used it during a blackout to keep our Wi-Fi running while charging my family’s devices. Filling a phone from zero barely makes a dent in the power station’s capacity, and it ran the router for several hours with plenty of juice left.
In another instance, it powered our small meat freezer for four hours before the power came back on with some juice still left in the tank. It does what it promises.
There are a few nice extra touches as well. Built-in wheels and an extendable handle allow it to roll like carry-on luggage. Unfortunately, those are necessary inclusions because it weighs a hefty 67.3 pounds. It’s manageable but definitely heavy compared to its competition.
The Anker 767 is compatible with the company’s 200W solar panels, which fold up for easy transportation. I mostly charged the unit through my home’s AC power, a surprisingly quick process. The 767 Portable Power Station can go from flat to more than 80% charge in less than a half hour with sufficient power. It takes about two hours to get it fully juiced.
Anker also offers a mobile app that connects to the power station via Bluetooth if you want to control it without actually going over and touching it.
Best for camping: Goal Zero Yeti 1000 Core
Buy it used or refurbished: eBay
Why it made the cut: Thanks to its outstanding portability, high storage capacity, and Yeti’s famous durability, the Goal Zero Yeti 1000 Core is great for packing along for camping or van-living.
- Storage capacity: 983Wh
- Input capacity: 600W
- Output capacity: 1,200W (2,400W surge)
- Dimensions: 9.86 x 15.25 x 10.23 inches
- Weight: 31.68 lbs
- Price: 1,198.95
- Highly portable
- Incredible durability
- Rapid recharge rate
- Plenty of plugs
Yeti is long-renowned for making some of the best outdoor gear money can buy, so when the company launched its Goal Zero line of solar generators, it was no surprise that they turned out to be awesome. While the whole line is great, the 1000 Core model’s balance between capacity and portability makes it perfect for taking on the road.
While the 1000 Core has a third less capacity than our top pick, it charges up faster, making it a great option for Rapid solar replenishment. That said, its capacity is no slouch, offering 82 phone charges, 20 for a laptop, or upwards of 15 hours for a portable fridge (depending on wattage). Suffice it to say, that it’s more than capable of powering your basic camping gear.
Beyond its charging capabilities, the Goal Zero 1000 Core excels at camping thanks to its hearty build quality. Built super tough—like pretty much everything Yeti makes—its exterior shell provides solid protection.
The biggest issue it presents is the cost. Like pretty much everything Yeti produces, its price tag isn’t small. While there are other 1000-level solar generators for less, this one offers a great balance of power storage and portability.

Why it made the cut: Thanks to its high solo capacity and ability to daisy-chain with additional batteries, the Bluetti AC200 Max is perfect for bringing power off the grid.
- Storage capacity: 2,048Wh standalone, expandable up to 8,192Wh
- Input capacity: 1,400W
- Output capacity: 2,200W (4,800W surge)
- Dimensions: 16.5 x 11 x 15.2 inches
- Weight: 61.9 lbs
- Price: 1,999
- Massive capacity
- Daisy-chain capability
- Lightning-fast input capacity
- 30A RV plug and two wireless charging pads
- Surprisingly affordable for what it offers
You’ll be hard-pressed to find a solar generator better suited for living off the grid for an extended period than the Bluetti AC200 Max. It boasts a substantial 2,048Wh capacity, allowing you to power your whole life off it longer than most portable generators. Even better, you can daisy-chain multiple Bluetti batteries, expanding its capacity to a massive 8.192Wh. That’s flat-out enormous and translates into the ability to power a full-sized fridge for over a day or several hours of air conditioning. For the more modest needs of people who are used to living off a generator, it will last for a very long time.
At the same time, the AC200 Max has an outstanding input capacity of 1,400W. That means you can plug in a pretty hefty array of solar panels to replenish its stores quickly. This allows you to keep your off-grid setup going with little to no interruption. It also features some specialty charging options, including a 30A plug, which lets you plug it directly into an RV, and multiple wireless charging pads for smaller devices.
Best for homes: EcoFlow Delta Pro
Why it made the cut: The EcoFlow Delta Pro delivers the standalone and expandable power capacity necessary to power your entire home.
- Storage capacity: 3,600Wh standalone, expandable up to 25,000Wh
- Input capacity: 6,500W
- Output capacity: 3,600W (7,200W surge)
- Dimensions: 25 x 11.2 x 16.4 inches
- Weight: 99 lbs
- Price: 3,699
- Enormous capacity
- Daisy-chain capability
- 30A RV plug
- Lightning-fast input capacity
- Wi-Fi and Smartphone connectivity
If you’re looking for the best solar generator for home backup in the event of a power outage, the EcoFlow Delta Pro stands apart from the pack, thanks to an unrivaled power and output capacity. The Delta Pro alone packs a 3,600Wh wallop, and you can expand that to 25,000Wh by chaining it to extra EcoFlow batteries and generators. That’s a ton of power and it has the substantial output capacity necessary to power an entire house worth of electronics when you need it to.
The Delta Pro also offers a companion app for iOS and Android that allows you to monitor energy usage, customize its operation, and monitor and manage a number of other elements.
While it’s not overly large for what it does, the Delta Pro is a heavy piece of equipment. It has wheels, so it is technically portable, but this is meant to be put down in a home or other semi-permanent site. Given its size and power, it’s also a much more expensive device, especially if you’re springing for the add-ons. As the best solar power generator to provide backup power for your entire home, however, it’s worth every penny.
Best portable: Anker 545
Buy it used or refurbished: eBay
Why it makes the cut: If you’re looking for highly portable power, the Anker 545 delivers.
When portability is a priority, the Anker 545 offers the compact size and reduced weight you’re looking for and packs fairly substantial power to boot. Roughly the size of a shoebox and lighter than a case of beer, it’s easy to pack along with camping gear and move around without too much effort.
To get something so light, though, you have to compromise on power. The Anker 545 has a capacity of 778Wh and an output capacity of 770W, which is plenty of power for keeping your devices charged. Specifically, that should provide about 55 phone charges, 10 for a laptop, or 38 for a camera. Unfortunately, the outlets only output at up to 500W, so it cannot power more demanding devices like hair dryers or electric stoves.
That said, the Anker 545 has some bells and whistles, including an integrated flashlight and ambient light. All told it’s a solid option if you need a highly mobile generator.
Best budget: Jackery Explorer 300
Buy it used or refurbished: Amazon
Why it made the cut: With its reasonable capacity, compact size, and solid build quality at a low price, the Jackery Explorer 300 is a great budget pick.
Though it isn’t quite as impressive as our top picks for best overall and best high-capacity, Jackery’s smaller Explorer 300 solar generator is super compact and lightweight with a decent power capacity for its price. Less a mobile power station than an upscale power bank, the 7-pound Jackery Explorer 300 provides plenty of portable recharges for your devices when you’re camping, on a job site, driving, or just need some power and don’t have convenient access to an outlet. Its modest 293Wh capacity isn’t huge, but it’s enough to provide 31 phone charges, 15 for a camera, 6 for the average drone, 2.5 for a laptop, or a few hours of operation for a minifridge or TV. A built-in flashlight would have upped its camping game somewhat, but at 300 (and often considerably less if you catch it discounted), this highly portable little power station does a lot for a little.
We tested this portable power station for several months, and it came in handy numerous times, especially during the winter when power outages abound. At one point, we had it powering two phones, a MacBook, and a small light.
The built-in handle makes it very easy to lug around. It feels like carrying a lunch box. The screen is easy to read, and the whole package seems fairly durable. Our review unit hasn’t taken any dramatic tumbles yet, but it has gotten banged around in car trunks, duffle bags, and other less-than-luxurious accommodations with no issues. If you catch one of these on sale, get it and stick it in a cabinet. You’ll be extremely glad to have it around when the need arises.
What to consider before buying the best solar generators
Over the past few years, solar generators have exploded onto the market. There are now dozens of different brands that largely look more or less the same at a glance. The fact is there are only a few standouts amidst a sea of knockoffs. Here’s what to look for to ensure you’re getting a great one:
How much power can it store?
A portable solar generator comes in an extremely wide range of sizes, but a generator’s size doesn’t automatically make it capable of storing a lot of power. In fact, most are disappointingly limited and unable to store much more juice than a portable charger.
To properly check a generator’s storage, you must look at its capacity, measured in watt-hours (Wh). One watt-hour is the equivalent of 1 watt flowing over the course of an hour. The best solar generators offer capacities of several hundred and sometimes several thousand watt-hours. That doesn’t mean, however, that it will provide power for several hundred or several thousand hours. Any generator will ultimately last a different amount of time, depending on what’s plugged into it.
It’s easy to predict how long a generator will last when you use it to power one thing. For example, if you were to power a 100-watt bulb using a power station with a capacity of 500 watt-hours, it would stay lit for five continuous hours. Add a portable fridge that requires 50 watts per hour, your phone which uses 18, a mini-fan that uses three … you get the picture. The more capacity, the better.
No solar generator will hold a charge forever, so you want one capable of charging as quickly and easily as possible. This is where we put the “renewable” into “renewable energy.”
All of the power stations included in this roundup can be charged by connecting them to solar panels (hence the designation “solar generators”). Still, you also want to look for the ability to charge via other sources like wall outlets and your vehicle’s 12-volt plug. This ensures that you can charge up whether you’re off-grid in the sun, plugged in while preparing at home, or using your dash socket on the go.
You must also monitor a model’s charging input capacity, measured in watts (W). For example, a solar-powered generator with a max input of 100W can take in a continuous flow of up to 100 watts, which is about the minimum that you’ll reasonably want to look for. Most of the generators below have input capacities of at least a few hundred watts when charging via solar, so a few 50- to 200-watt solar panels will max them out.
Solar generators need to keep the power coming in and going out. The best solar generators can simultaneously charge all your intended devices via whatever plugs are necessary.
Any portable power station worth your money will have a high output capacity so you can charge many devices, even if they require a lot of juice. A generator’s maximum output should be much higher than its max input. While a particular model might only be capable of taking in a few hundred watts at any given moment, it will usually put out exponentially more. At a minimum, you’ll want a generator that can put out 300 watts at a time, though you’ll want at least 500 for larger tasks.
The best solar generators should also offer a variety of output plugs, including AC outlets, USB-A, USB-C, and even 12-volt DC outlets like the one in your vehicle dash. This ensures you can charge several devices simultaneously regardless of their plug. The number of ports you’ll need will vary depending on how many devices you need to power, but it should have at least a couple of AC outlets and a few USB-A ports.
While portable battery sources have been around for a while now, over the past several decades, they’ve been pretty heavy, unwieldy things. One of the most exciting aspects of the latest generation of solar generators is that they’ve become much more physically compact.
Suppose you plan on taking a generator camping or working it into a van conversion where every square inch matters; well, size and weight become major considerations. All of the products we’ve recommended are about the size of one or two shoeboxes—three at the most. The lightest is about the weight of a 24-pack of soda, while the heaviest is 100 pounds. Most fall somewhere between 30-60 pounds.
If you’re using your generator as a more or less stationary source of backup power at home, portability isn’t a huge issue. Still, we generally recommend keeping weight and size in mind; You never know when you’ll need it for something other than a backup. (Plus, who wants to lug around something heavy and awkward if they don’t have to?)
Another consideration regarding portability involves the necessity for accessories, which can impact how easy it is to move and use your generator. Some generators, for example, require a lot of removable battery packs, which can be a hassle when you’re on the go or packing a vehicle. All of the inclusions on our list require some accessories—you can’t get solar power without connecting cables and solar panels—but they work well with minimal add-ons.
As with any product you expect to last, durability and all-around quality craftsmanship are essential. This is especially true if you plan on lugging your generator around on camping and road trips. Many subpar power stations are made from cheap components and flimsy plastic that doesn’t feel like it will hold up under the rigors of the road.
Durability isn’t something you can determine by reading a spec sheet off the internet. You’ve actually got to take the generator out, use it a bunch, and see how it holds up. I’ve verified the durability of these recommendations via a combination of my own actual field tests and reviews culled from countless real product owners.
Q: What size solar generator should I get?
It’s easy to underestimate how much capacity you need. A 1,000 watt-hours might sound like a lot, but if you’re going to power a converted van with a portable fridge, lights, and occasional phone and laptop top-off, that 1,000 watt-hours will go faster than you expect. I used a setup like this and know from personal experience that you should always overestimate how much power you’ll need.
A generator with a capacity under 1,000Wh can keep electronics charged. A larger one with 1000-1500Wh should be the minimum for road trips where you’ll need it to last multiple days between full charges. For a house or worksite where you expect to use some serious energy—like a full-sized refrigerator or power tools—you’re going to want to start looking at the biggest possible power stations that can be daisy-chained to external batteries.
If you want to get precise, there is an equation:
Estimate how many hours you’ll need to power various devices. For example, if you want to power two light bulbs for 2 hours: you need 4 hours of operation.
Add up the total wattage necessary: the two bulbs are 60 watts each, so you need 120 watts.
Multiply these together to find the total watt-hours needed: 4 x 120 = 480. So, in this case you’d need at least a 500Wh solar generator.
That might sound like a lot for two lightbulbs, but remember that, in most situations, you won’t really be powering 60-watt light bulbs for hours on end. You’ll be charging phones and laptops for an hour here or there, cooling a fridge that kicks on and off every once in a while, using power tools in short bursts, and whatnot.
Q: How many years will a solar generator last?
Most modern generators are rated to last upwards of 25 years. The best-designed power stations are pretty sturdy, with few to no moving parts, so they should likely keep kicking for a long time, provided that you care for them properly. I’ve been pretty rough with a few of mine, and they show no signs of stopping.
Q: Can I run my house on solar power only?
Yes and no. While it’s absolutely possible to power your house with solar power, you’re unlikely to do so with a portable solar generator unless you use several at once while limiting your power usage. The largest of our recommendations—the EcoFlow Delta Pro—will come fairly close when bolstered with extra batteries. If the power goes out, you’ll be able to keep your fridge cold and use basic electronics for a couple of days without recharging. With quality solar panels, good sunlight, and Smart energy usage, your power should theoretically go uninterrupted.
Final thoughts on the best solar generators
We’re living in a “golden age” for portable solar generators. When I was a kid, and my family was playing around with solar gear while camping in the ‘90s, the technology couldn’t charge many devices, so it wasn’t all that practical.
By contrast, the solar generators we’ve recommended here are incredibly useful. I’ve relied on them to power my work and day-to-day needs while road-tripping nationwide. They’re also great when the power goes out. When a windstorm cut the power at my house for a couple of days, I was still working, watching my stories, and keeping the lights on.
We haven’t even scratched the surface in terms of the potential offered by portable, reliable, renewable, relatively affordable power. What we can do now is already incredible. The potential for what may come next, though, is truly mind-blowing.

What makes BLUETTI’s solar generators last longer? – LiFePO4 battery cells
SPONSORED NEWS – It all started with the EB150 and EB240 solar generators, Bluetti’s first products launched back in 2019.
Approximately one year later, they released their flagship model the AC200 on Indiegogo (which was powered by NCA cells), as a crowdfunding campaign.
This project pulled in nearly 7 million dollars in two months.
Since then, Bluetti has been at the forefront of technological innovation and has equipped all its new products with LFP technology over both NCM, NCA lithium-ion battery chemistry.
You may be asking yourself why they did this. Well, in this article, we aim to explain their reasoning as best we can.
What Are LiFePO4 Batteries?
LFP or LiFePO4 stands for Lithium Iron Phosphate and was invented back in 1996.
For all the science geeks out there, its anode material is LiaC6, and the cathode material is LibFePO4, with the carrier being Li.
LFP batteries provide some of the best electrochemical performance with added lower resistance on the market.
This is made possible by the nano-scale phosphate cathode material found in the battery.
This allows for the following benefits:
- Long life cycle
- Thermal stability
- Higher current rating
- An extra layer of safety
How Do LiFePO4 Batteries Work?
An LFP battery is essentially made up of the following components:
- Positive electrode (cathode)
- Negative electrode (anode)
- Lithium metal oxide (LiFePO4)
- Lithium salt
- Polymer membrane Charging
When a LiFePO4 battery is being charged, lithium ions are released from the cathode and move to the anode. They do this via the electrolyte.
When a power load is applied to the battery, the opposite reaction takes place. Lithium ions move from the anode to the cathode.
This movement of the lithium ions creates an electron flow between these two electrodes, which generates an electric charge.
LiFePO4 Batteries vs. NCM Lithium-Ion Batteries
For this section, we thought it best to create a comparison table of Bluetti, Jackery, and Ecoflow.
Bluetti uses LiFePO4, Jackery lithium-ion, and Ecoflow NCM.
(For the reader’s information, Bluetti could not find a comparable capacity size for the Jackery, so Bluetti included their largest capacity generator, which is 1,534 Wh.)
Next, we want to figure out the LCOS or Levelized Cost Of Storage in USD/Wh.
When it comes to energy storage, one cannot simply rely on the actual buying price of the solar generator (up-front cost).
We also need to take into account the total energy in watt-hours that the solar generator can store and release (the charge/discharge cycle) during its lifetime.
The formula to work out the LCOS is the following:
LCOS = Upfront Cost / (total kWh capacity x (DoD %) x cycle life)
Let’s work out the LCOS for each solar generator manufacturer and their respective product models.
Bluetti 2 kWh x 0.9 x 3500 = 6300
1,799 / 6300 = 0,285 per kWh
Jackery 1.5 kWh x 0.8 x 500 = 600
1,599 / 600 = 2.67 per kWh
Ecoflow 2 kWh x 0.8 x 800 = 1280
1,899 / 1280 = 1.48 per kWh
As we can see when working out the LCOS, Bluetti is by far the much cheaper option over the long run, and this is because the LiFePO4 technology lasts much longer than both lithium-ion and NCM.
Do keep in mind that the above LCOS includes other components such as the charge controller and inverter, as these two components are included in the upfront purchasing price.
Why LiFePO4 Batteries Are The Perfect Fit For Solar Generators
To highlight this section, we thought it best to highlight all the advantages LFP batteries have and why they are best suited for solar generators.
Lightweight LiFePO4 batteries are known to be lightweight in comparison to other battery technologies. This is particularly important when their application is found inside a solar generator. The less heavy a generator, the more mobile it is. For example, Bluetti’s new AC200 MAX weighs only 61.9lbs (28.1kg).
While this may sound like a lot at first glance, you have to remember just how much energy storage capacity this machine has got. For all that energy density, 61 pounds is next to nothing.
Long Life-Span Perhaps one of the greatest perks of the LFP battery is its ability to charge and discharge thousands of times. In Bluetti’s case, their latest solar generators can discharge over 3500 times.
This is a significant decision-making factor for consumers looking to invest in high-quality products that will last them many years to come. LiFePO4 technology allows this.
High Efficiency Unlike lead-acid batteries, LFP batteries are incredibly efficient. You can use up to 90% of their capacity, meaning you can get the most out of your solar generator for as little space used as possible.
Generally, LiFePO4 batteries can be discharged beyond 90% of their capacity.
No active maintenance LFP batteries require pretty much no maintenance. This means you do not need to do anything to extend its lifespan. You can simply charge and discharge as you see fit.
Safety LiFePO4 batteries are indeed safer than NCM batteries. In fact, they are the safest lithium-ion battery on the market.
These batteries are encased in an airtight aluminum case, specifically designed to withstand temperature, pressure variations, punctures, and impacts.

What Makes BLUETTI’s Solar Generators Last Longer- LiFePO4 Battery Cells
BLUETTI has been at the forefront of technological innovation when it comes to portable power stations. It all started with their flagship models, the EB150 and EB240 solar generators, launched back in 2019. Then the AC200 in 2020 was a massive success that it pulled in nearly 7 million dollars in just two months. From then on, BLUETTI only continues to up the scale with new models, this time powered by the highly durable and reliable LiFePO4 battery.
You may be wondering. What makes BLUETTI’s power stations stand out in the oversaturated market of portable generators? Well, it’s the battery chemistry. Instead of the archaic diesel or fuel-powered engines, BLUETTI equips its machines with LFP technology over both NCM, NCA, and lithium-ion battery chemistry.
What Is LiFePO4 Battery
Lithium Iron Phosphate (LFP or LiFePO4) made its way to the market in 1996 and has since been known to provide the best electrochemical performance. This is due to its composition: its anode material is LiaC6, the cathode material is LibFePO4 (lithium iron phosphate), and the carrier is Li. It is essentially made up of a positive electrode (cathode), a negative electrode (anode), electrolyte, separator, lithium metal oxide (LiFePO4), graphite, lithium salt, and polymer membrane.
How Does It Work
During the charging process, the batteries release lithium ions from the cathode to transport them over to the anode via the electrolyte. The opposite reaction takes place during power discharge. The lithium ions move from the anode to the cathode and the movement is what creates the electric charge that supplies the power.
BLUETTI’s Edge Over The Rest
BLUETTI made a great choice with the use of LiFePO4 for their solar generators. This is especially ideal when durability, safety, and high performance are at the forefront. After all, you don’t want your machine catching fire or reeking of smoke. Worse, dying on you when you need it the most. This is where the beauty and functionality of BLUETTI’s solar generators come. Since they run on LiFePO4 batteries, then you can be certain of durability and safety.
LiFePO4 batteries have an edge over lithium-ion, both in terms of lifespan and safety. Whereas the former can overheat and catch fire, the latter doesn’t, even when punctured. That’s because the nano-scale phosphate cathode material in the battery isn’t hazardous. This means it doesn’t pose any health or environmental risks.
over, LiFePO4 batteries have a higher current rating, are lightweight, and have a life expectancy of seven years or ten at most. They can operate in a wide range of temperatures thus making them ideal for both indoor and outdoor use.
You can check out the comparison below to know why BLUETTI’s solar generators are a great choice over other NCM or lithium-ion-powered ones. They are a much cheaper option when you’re looking at getting your money’s worth in terms of overall performance in the long run.

(For the reader’s information, we could not find a comparable capacity size for the Jackery, so we included their largest capacity generator, which is 1,534 Wh).
Next, what we want to do is figure out the LCOS or Levelized Cost Of Storage in USD/Wh (LCOS = Upfront Cost / (total kWh capacity x (DoD %) x cycle life) When it comes to energy storage, one cannot simply rely on the actual buying price of the solar generator (up-front cost). We also need to take into consideration the total energy in watt-hours that the solar generator can store and release (the charge/discharge cycle) during its lifetime. Also, keep in mind that the above LCOS includes other components such as the charge controller and inverter, as these two components are included in the upfront purchasing price.
1,799 / 6300 = 0,285 per kWh
1,599 / 600 = 2.67 per kWh
1,899 / 1280 = 1.48 per kWh
Why Choose BLUETTI’s Solar Generators
BLUETTI prides itself on providing only the best when it comes to its solar generators. As such, the company relies on LiFePO4 batteries to cater to both light and heavy-duty use. These batteries can charge and discharge thousands of times and BLUETTI’s latest models can discharge over 3500 times.
For example, the AC300 has the ability to max out at 240V, 6,000W, and a total of 24,576Wh when combined with the Fusion Box Pro. This allows you to connect two units of the AC300 in series and connect up to 8×B300’s (four for each AC300).
