How To Choose A Lithium Battery Solar Generator

Choosing a lithium battery solar generator is a commendable affair. The pollution in the earth has reached its precipice. It's just waiting for a small thing to tip the scale. Being one of those who choose healthy alternatives such as solar-charged gadgets to fuel, You should be proud of yourself.

A solar generator has many advantages. For one it uses the sun. So you do not have to waste money buying fuels. What's more, it keeps our homeworld safe. Once you purchase one, all it needs is frequent maintenance. The only work here is how to choose a good lithium solar battery that meets your needs.


The type of battery in the solar generator is vital in influencing your choice. There are many types you could choose from. Below are two types of batteries that you can choose from.

We have explained under each battery what makes it different or unique from others. By checking that out you should be able to choose the one that fits your needs.

1. Lead-acid batteries

Invented in 1859 lead-acid batteries are the first rechargeable batteries created. The battery is low-cost and it can provide a high surge current. These attributes and more makes it highly sought after. This is so even after newer models were made.

Its ability to store charges is remarkable. Statistics have shown that lead-acid sold accounted for about 50% of batteries sold in 1999.

It is highly sought-after, even when surge current is not a crucial factor.

More so, it is excellent for backup power supplies such as generators. For places that need 24/7 uninterrupted power supply, such as hospitals, schools, and others.

However, if overcharged there is a risk for combustion. This is due to overheating. Normally when it overheats the valves do their job and lower the pressure. However, the valve may also malfunction due to the accumulation of dirt or other factors.

2.  Lithium-ion batteries

One of the most environmentally friendly technologies created. It transfers ions from the negative to the positive through an electrolyte. It does this vice versa when charging.

It's a good battery for any gadgets that need to hold electricity for a long period. More so, its components are relatively safe compared to other batteries.

Its capacity as of 2010 is stated to be 20 gigawatts-hours. And it's estimated to reach 200-600 as of 2023. An impressive improvement if done.

It had different designs, but manufacturers knew the best to pick for their productions.

What to do is consider a lithium battery solar generator

Each person in the organization has their specific electricity needs. Depends on what you need a power supply for, how long, and how much.

Below are some things you might want to consider when choosing your solar power generator.

1. Weight

Weight is a crucial factor in choosing a solar power generator. The bigger it is, is relative to how much capacity it has. And how fast it can take in and convert solar power to electrical then light.

2. Capacity

Again, your electricity needs determine the capacity of the generator you get. If all you need is about 5kw then you look for something in that range. Although the ideal Kw for a home is 10kw. You might want to start from that range.

You could also be a huge corporation, big hospital, a lab, or a factory. These places require a huge power supply so you need a bigger supply for them. Around 30-50kw or more. It depends on your need for the generator.

3. Cost

Of course, you have your budget. So you need to look for a lithium battery solar generator that meets all demands closest to your budget. Solar generators usually cost around $100-$500 low-capacity solar generators. The higher-capacity solar generators cost around $2000-$3000.

Although the installation might be a bit pricier than fossil generators, they are cheaper to maintain. After the initial capital used to buy and install all you need is sub from then.

4. Charging ways

Charging a solar generator is not hard. Just put the solar panels out in the sun and bingo it gets charged. The cells convert the sun to chemical energy in the generator. Very much like the chlorophyll on the leaf of a plant. Nature teaches us a lot.

The thing is just that, the amount of time to leave the generator outside varies. It depends on the capacity, weight, and body width of the cells converting solar power.

So some lithium battery solar generators have to remain outside for 4-5 hours while bigger ones might use up to 7hrs or more. You should check this before getting your solar gen.

You may also use a car outlet to charge a solar generator.

3 best lithium-powered solar generators you can get

Some solar generators are just enough to power gadgets such as your phone, laptops, torchlight, and more. While some can power whole buildings and labs.

Check out some of the best generators for different capacity needs below.


Weighing 21.3 pounds, BLUETTI EB70 is a small capacity generator. From prestigious company BLUETTI.  Its output power is around 700W. What's more, it has a foldable hand design, which makes handling it easier.

This is the perfect generator for camping. It can charge phones and laptops fully many times over. It's like carrying your light supply when out in the wilds or desert.

It has a 200w solar power input, which can be fast-charged within 4.5hrs. It cost as low as $599. This is just perfect for outdoor pleasure lovers.


Another excellent power station from BLUETTI. This is one you will surely love. Its capacity is 2048. Can take in about 900W solar input and more.

Its charging is relatively the same as all other power stations. A cable is routed to a wall charger or car charger. 


BLUETTI EP 500 is another masterpiece from BLUETTI. Attracting more than 750 investors. However, right at its tail introduced EP500 PRO. This is a better alternative to EP500. However, it still had some of the basic qualities of EP 500 with more upgrades.

It has been lauded as the best mobile solar battery in the world. The mini solar generator has a capacity of 5100Wh. This ensures that you are always in good hands in any solar outages.

Pros and cons of lithium battery solar generators

Lithium batteries have their pros and cons.

Some of its pros are;

  • Long life
  • Good temperature
  • Fast charging
  • Not heavy
  • Safe to handle

Meanwhile, it's has conned such as

  • Last less than 4yrs
  • Can not be charged with a disabled battery.
  • It is costly


Q1. Can lithium batteries be solar charged?

Yes. Lithium batteries can be solar charged. But it can easily damage if overcharged or by just regularly charging it.

It requires a special charge controller to regulate the level of charges coming in. Without this feature the lithium battery will spoil in no time.

Q2. How long can a lithium battery solar generator power a refrigerator?

The length a solar generator can charge a fridge or freezer depends on the generator. Each generator has different capacities. It also depends on how strong and how much power the fridge requires.

A 100w generator for example can give out about 500w during the day. This is around the amount required by an average home fridge and all.

Q3. Can a battery-powered generator power a house?

Yes, you can safely use a battery-powered generator to power a house. It is better than its fossil fuel counterpart. The fuel generators require intensive care and cannot be used inside the home. Although the solar gens are pricier than their fuel counterpart, it makes up in the long run with their cheap maintenance. No more buying fuels, bye-bye to that.

Q4. How to charge your battery power stations?

A cable always comes with the power stations. You then connect these stations to the car charger or a wall charger with an output of at least 3A.

Depending on your battery power station you can use it within 2-6hrs to charge a battery power station.


With the right information getting a good battery station is a breeze. Lithium battery solar generators are good alternatives for fuels even better. There is no doubt about this. To choose a solar power station you should consider capacity, size, weight, and cost. You can also consider buying BLUETTI EP 500 PRO and BLUETTIT EB70.
