LiFePO4 or Lithium-ion Batteries for Solar Generators, What are They?
For powering a solar generator, you have multiple options. lithium-ion batteries, lithium iron phosphate, lead acid, and nickel-cadmium. Each battery types offer advantages and disadvantages. Choosing the correct type of battery is crucial for ensuring a reliable solar power system. Which one is the best choice for your solar generator? It’s hard to decide when there are so many factors to consider. Before that, we discussed the difference between LFP VS NMC Battery. In this article, we’ll mainly discuss the most popular option. LiFePO4 vs lithium-ion batteries so that you can decide which type of battery best fits your needs.
What are Lithium-ion Batteries?
Lithium-ion batteries are a popular type of rechargeable battery commonly used for portable electronics, electric vehicles, and residential solar systems. With their high energy density, long lifespan, lack of memory effect. and relatively low maintenance, lithium-ion batteries are a great choice for many applications. Despite the costly production of lithium-ion batteries, their popularity and increased use have driven down over time.
What are LiFePO4 Batteries?
Lithium iron phosphate batteries, or LiFePO4 batteries, are a new type of battery made with a different cell chemistry than lithium-ion. Unlike lithium-ion batteries, LiFePO4 doesn’t contain cobalt, making it the more environmentally friendly choice. LiFePO4 batteries offer several advantages over other lithium-ion batteries, including higher security, longer life cycles, and improved performance across a wider range of temperatures.
Why Lithium Iron Phosphate Batteries are the Best among Lithium-ion Batteries?
Safe, Stable Chemistry
Safety is one of LiFePO4’s most significant advantages over other battery types. The most secure sort of lithium battery is LiFePO4. Actually, it’s the safest type of all.
Generally, the most secure lithium chemistry is found in LifePO4 batteries. Why? due to the greater thermal and structural stability of lithium iron phosphate. The majority of other lithium-ion batteries don’t have this to the same degree that LiFePO4 does. LiFePO4 is not flammable. It resists decomposition in high temperatures. It will maintain a cool temperature at room temperature and is not prone to thermal runaway.
Excellent Efficiency and Performance
LiFePO4 batteries have a lower energy density of 90 to 120 Wh/kg than other lithium-ion batteries, but they can still store a decent amount of energy in their cells. This makes them an ideal choice for smaller applications that don’t require as much power, such as solar generators.
The storage capacity of a LiFePO4 or lithium-ion battery will also depend on its environment, as temperature and other factors can play a role in its performance. Storing your batteries in a cool place helps preserve and extend their lifecycle rating, which can help provide more consistent power output over time.
Enduring with Longer Battery Life
Other lithium-ion batteries have a shorter lifecycle than LiFePO4 batteries with an average of 500-1,000 cycles, meaning they must be replaced more often. This can be costly over time and can make other lithium-ion batteries less attractive for solar generator applications.
While LiFePO4 batteries are known for their long life of 3,000-5,000 cycles or more, making them a more cost-effective option for solar generator applications. The cells are also designed to be safer than other lithium-based chemistries, reducing the risk of fire or explosion in the event of an accident.
Environmental-Friendly
LiFePO4 batteries do not contain any hazardous materials, making them more eco-friendly than lithium-ion batteries. These batteries are built with non-toxic materials such as iron, graphite, and copper, and their extended lifespan reduces the need for manufacturing new batteries.
They contain phosphate salts instead of metal oxides, which are safer for the environment in case of disposal.
Other lithium-ion batteries contain hazardous materials, and their disposal or recycling can be difficult. Once disposed of, other lithium-ion batteries can negatively impact the environment.
Lithium-ion Batteries
Lithium-ion batteries are commonly used in consumer electronics such as laptops, mobile phones, and cameras because of their high energy storage capabilities and low self-discharge rate. They are also used in some electric vehicle applications, as they can store a large amount of energy while taking up a relatively small amount of space.
Lithium Iron Phosphate (LiFePO4) Batteries
LiFePO4 batteries offer a higher capacity than other lithium-ion batteries but with a lower energy density. This makes them ideal for large-scale stationary applications, such as solar or wind power systems, which require more space to store the same amount of electricity compared to lithium-ion. They have a much longer cycle life than conventional lead-acid batteries and their self-discharging rate is much lower, too.
Conclusion
For solar generator applications, LiFePO4 is considered to be the better choice because of its higher energy density, improved safety features, and longer lifecycle. However, other lithium-ion batteries have their own advantages, such as cost and faster charge times. Ultimately, the right option for your application will depend on factors such as budget, expected lifecycle, and performance requirements.

Why Should You Choose a LiFePO4 Solar Generator?
One of the main reasons you should choose a LiFepo4 solar generator is that it uses a lithium iron phosphate (LiFePO4) battery. Compared to lead-acid batteries, LiFePO4 batteries usually have several advantages, including enhanced discharge efficiency, a long lifespan, and the capability to deep cycle while maintaining optimal performance.
Image Source: bestportablesolargenerators.com
Other reasons why you need to consider LiFePO4 solar generators include the following:
Lightweight
Lead batteries are nearly four times heavier than LiFePO4 batteries of the same capacity. For example, a 150Ah lead-acid battery can weigh up to 48kg, but a LiFePO4 battery of the same capacity weighs just 14 kg.
Fast Charging
LiFePO4 batteries usually charge quickly and consistently until they reach 100 percent capacity. On the other hand, a lead-acid battery takes time to absorb its last 20 percent charge.
Safety
LiFepo4 batteries are exceedingly safe to use because of their stable chemistry. Even in case of a fire, a short circuit, or an accident, these batteries will not explode. Furthermore, you can use their full capacity without the risk of explosion.
Performance
LiFePO4 solar generators have a substantially longer life span than normal lead-acid batteries. Besides, the LiFePO4 batteries have a life cycle of up to 2500 cycles and can run perfectly for 7-15 years.
Climate Resistance
Both LiFePO4 and lead-acid batteries would lose their capacity in harsh weather conditions. However, compared to lead-acid batteries, the energy loss from LiFePO4 batteries is less. As a result, your LiFePO4 battery will likely keep up to 80 percent of its capacity at.20 degrees Celsius, compared to 30 percent when using an AGM battery.
Noise Level
Regular generators can be quite noisy, which can be an issue if you use them while RVing, camping, or even operating them outside your house. However, one of the advantages of LiFePO4 solar generators is that they silently operate because they lack all of the components found in gas-powered generators.
Factors to Consider Before Buying the Best LiFepo4 Solar Generator
Portability
Whether you are looking for a solar generator for backup power at home, camping, or loading onto your boat, you need a relatively easy unit to carry along. If you enjoy being outdoors, you know what we are talking about. If you are camping, you already have a lot of gear to carry along, and a solar generator isn’t the lightest on the list.
Image Source: railadvent.co.uk
We recommend investing in portable power stations that will make your camping enjoyable. Go for one with a sturdy carrying handle or one with wheels for easy maneuverability.
Battery Capacity
Before buying the best LiFepo4 solar generator, you must determine how long the battery can run your appliances without charging. The value is expressed in watt-hours (Wh). For instance, a 3000Wh generator can power a 100W TV for 25 hours, a 1250W electric grill for 2.4 hours, or a 60W laptop for 50 hours.
To determine the best generator capacity for your needs, add all the power ratings you intend to use simultaneously, then multiply by the number of hours. Let us say you need to power:
For seven hours every day
420W x 7 h = 2940Wh is what you need
Solar Charge Controller
Although solar generators are designed with utmost precaution and have little to no danger of failure, check whether the one you intend to purchase has installed a solar charge controller or an integrated MPPT charge controller (maximum power point tracking).
Image Source: bluettipower.com
There is always the possibility of overcharging or overcurrent being supplied to the device while charging the solar generator through a solar panel or an AC or DC outlet, which can critically damage the battery. These charge controllers are usually installed to prevent this. The work of these charge controllers is incredibly easy.
They limit the flow of electricity to the generator while it is plugged in and stop it when it’s fully charged. Hence, you can charge the solar generator overnight or during the day without causing any issues with the battery. MPPT is a relatively new addition to charge controllers that are more secure and energy-efficient than their predecessors.
I/O ports and Charging Options
The main input method for a solar generator is a solar panel system that can be directly connected to the unit. Once it’s connected, the solar panels can provide a free charging option for the generator and free energy to use.
Although it appears to be the best input method for a solar generator, it’s not always the most practical since you cannot charge it through a solar panel. Some reasons include wet weather, dark woodlands, or damaged solar panels. In such a circumstance, an additional input method on the solar generator, such as AC or DC input, can be a lifesaver.
Durability
When buying the best solar generator for home backup and emergencies, consider its durability and overall quality. This is especially crucial if you intend to carry your generator on camping and road trips. Unfortunately, many poor power stations are made of cheap components and weak plastic that does not feel like it can withstand the rigors of the road.
Image Source: solarreviews.com
Durability cannot be determined by reading a specification sheet on the internet. It would be best to take the solar generator out and see how it holds up. I have used and tested the durability of these recommendations.
Additional Features
Before buying the best lifepo4 solar generator, check for additional features such as multiple USB ports, rechargeable batteries, AC outlets, and LED displays that allow you to monitor your system in the dark. Conversely, look for units with warranties manufactured by companies with established solar industry credentials.

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)
- Electrolyte
- Separator
- Lithium metal oxide (LiFePO4)
- Graphite
- 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.
Extreme temperatures Bluetti’s solar generators are able to operate in a wide range of temperatures, which means they can be used for a variety of applications.
Temperature is not something to overlook when it comes to battery performance, and it can have a profound effect on any battery. However, LiFePO4 stands the best chance in extreme temperature variants.
Final Thoughts
If you are looking for the safest solar generator with the greatest chance at providing you with long-term energy storage, then all Bluetti solar generators equipped with the latest LFP technology is your best bet.
Models such as the new AC200 MAX and the AC300 modular power system are capable of providing you with incredible amounts of energy storage.
For example, the AC300 has the ability to max out at 240V, 6,000W, and a total of 24,576Wh when combined with our 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).
