Top 3 Most Powerful Solar Generators (Overview + Analysis)

5.0 rating

Clunky generators of the past were known for a few specific features.

They were often big, took up a lot of energy, but also output a good amount of energy in return. The only problem with these mammoths was that they were loud, often stationary, and off-gassed many unnecessary and harmful fumes.

Generators in this day and age are far cleaner, quieter, more efficient, and have become a portable lifesaver for so many.

They provide more than their former counterparts’ energy outputs and come with plenty of options for a truly customizable experience. 

But what are some of the most powerful solar generators on the market? And what are the features that make them so powerful?

In short, there are only a handful of solar generators that exceed all others in terms of power, but there is one that stands out from the rest.

The most powerful solar generator is the Titan solar generator by Point Zero Energy. The three main factors that set this apart from the competition include:

  1. Up to 2000W of solar input
  2. 3000W continuous, 6000W AC surge power
  3. 2000Wh stackable lithium-ion battery pack

Including the Titan, we’ve compiled the top three most powerful solar generators on the market and one incredibly special feature that we can’t wait to tell you about. First, let’s dive into the features that make solar generators more powerful than others.

What Features Should You Look For?

While they aren’t all built the same, solar generators will have some universal features for truly powerful charging stations. Some of these common features are: 

High Price Point

Because these power stations are so high-powered, they are made up of a lot of expensive technology.

You’re essentially paying for these generators to be made with the best materials that will work together to help the generator properly function.

Things like high-capacity lithium batteries, expansive solar compatibility, and durable materials; they add up pretty quickly. Cost isn’t something that should deter you as these generators are built specifically for heavy-duty loads, so you are paying for them to be ultra-reliable and powerful enough to withstand. 

Lithium Battery

The lithium battery is perfect for these generators as they are one of the largest available with the highest capacity. They have little risk of burning out and have up to a 10-year lifespan.

This is wonderful because you’re investing in a device that will last for a long time without the need for replacement.

Replacement batteries for such a big piece of equipment can be expensive, so you want to know that you’re investing in something that won’t fall apart in just a few years or less. 

Another lithium battery type is called lithium-iron-phosphate (LiFePO4) and these batteries are safer and last much longer than the standard lithium-ion battery (in many cases 5-10 times longer!).

I wrote an article on specific solar generators with LiFePO4 batteries and you can find it here: 6 Best LiFePO4 Solar Generators (Stats, Pricing, and Analysis).

High Battery Capacity

This should go without saying, but these larger generators are so sought after because their higher wattage enables them to power your devices for longer periods of time.

The fact that they can withstand so much is why they are so useful.

These generators tend to be in the watt-hour (Wh) range of 1000+.

Power Expansion

Not all of them, but a great deal of them come with the ability to expand their battery power. This means they can charge up twice as fast and can even be coupled with other generators or batteries to power more devices at once.

So now that we’ve compiled a list of all the things a hyper-powered generator should have, what brands have what we’re looking for? Follow along to find out. 

Titan – Point Zero Energy ($2,995)

The Titan is the perfect name for this powerhouse as it truly encompasses just how much bang you’ll be getting for your buck. One of the fantastic parts of this piece of equipment is that your package is truly customizable.

The basic package comes with the generator itself, as well as a cigarette to SAE to allow for car charging, MC4 to SAE for solar panel charging, 30W USB adaptors, an AC charger, and a manual.

These are the most basic of features that are included with most generators, but this also comes with a few other special features—things like a removable extendable lithium-ion battery and the 2000W lithium battery. But there is so much more you can add on. 


The extension packages can be customized for your needs, and you can add on a solar panel that ranges in options from 500W to 2000W, these, of course, will come at an extra price.

Solar panels can be incredibly pricey, especially considering how much wattage you’re going to need. They can bring your price point up from the $2,995 price tag by at the very least almost $1000 to up to $3,000 of either rigid or flexible solar. 

You can customize your battery packs as well by adding on up to four. These extra batteries are crucial if you’re planning on powering a lot with this generator or wanting to stock up for emergencies.

These batteries are, of course, built to last, but if you’re planning on staying somewhere for a long period of time without the ability to charge things up for a while you will want to have the option of replacing the battery should you need to. 

If you need extension cords for your solar panels, you can also add those on to your order for an additional cost. These cords run anywhere from 25 to 100 feet in length.

In addition to cords, extra batteries, and solar panels, you can also add on an extra AC charger for less than $250. In any situation you may come across, the Titan will make sure you have all the power and extra power you may need. 

What Sets the Titan Apart

Titan has cornered the market by utilizing a 3000-watt pure sine wave inverter, which doubles the power of other brands.

This allows it to run faster and more efficiently but doesn’t draw on the power as much as you’d expect for something of its energy level. 

The Titan is also made up of quality materials that will handle higher voltages without breaking down but is lightweight and durable. If you’re looking for a heavy-duty generator, you’ll want something that is going to be able to withstand the test of time.

Titan doesn’t use cheap materials that other power stations might. The cheaper materials tend to lead to overheating, parts breaking down, and will have low amps to take on high voltages.

  • Solar Input Max: 1000W (one battery); 2000W (two or more batteries)
  • Power Output (Peak): 6000W
  • Power Output (Continuous): 3000W

With so much to choose from for customization and all the truly heavy-duty features, the Titan is not only one of the most powerful generators on the market, but it is also a fantastic investment.

The Titan is one of my favorite solar generator systems because it can power appliances for longer than most of the competition.

I’ve featured it as one of the best solar generators in several of my articles regarding high-power needs, including the best solar generators for:

You’ll be getting plenty of special features for the higher price point, and this power station will be able to stay up and running for hours and even days at a time, depending on what you’re using it for.

Investing in the Titan means putting your money towards something that is worth your time and energy.

YETI 3000 Lithium – Goal Zero ($2999.95) 

Yeti 3000 Lithium front view

Each of these power stations has a few specific elements that make them different than the rest. The Goal Zero YETI 3000 Lithium is the largest power station that Goal Zero currently has on the market as of late 2020.

The YETI 3000X is the successor of the Lithium model but has the same battery size. The 3000X, however, has several other increased attributes, including but not limited to, a larger inverter capable of 2000W continuous and 3500W surge capacity.

It boasts itself as being one of the highest-capacity generators you can get, coming in at 3000Wh, it is the highest capacity on this list as well.

This power station has even been considered to have industry-leading components like their ten ports that are versatile enough to suit any gear you may be bringing with you. 

The YETI 3000 is also incredibly customizable, with plenty of additional features and accessories that only add to the overall power, accessibility, and portability of this generator. 


Goal Zero has taken all of the complicated work out of finding the right solar panel to suit your charging needs. They have pairing recommendations set up based on your usage.

For those who use their power station casually, they recommend the Boulder 200 Briefcase. This is a portable solar panel that folds up and has a handle for easy carrying.

It will charge your generator up much slower than other higher powered panels, getting it up to a full charge between 18 and 36 hours. While that may seem a bit too slow, if your usage is light, it is a great thing to just set aside for charging and then put away when you need it. 

For medium or general usage, they recommend you double up on the Boulder Briefcase 200. It will charge your generator up in 9 to 18 hours depending on the sunlight conditions, but it is ideal if you’re using your generator regularly.

However, if you’re using your generator frequently, as in nearly every day or almost every day, you’ll want to invest in three of the Boulder Briefcase 200s. With all of them paired up to help charge your station, they can have it at full power in as little as 6 to 12 hours. 

You can also store your energy by pairing up their versatile home storage system, which can back up four extra batteries.

This is also recommended if you’re using your generator nearly constantly as you can change out one while another is charging, giving you uninterrupted power.

You can hook up less expensive lead-acid batteries, which are cheaper to purchase for multiple backups and can easily work with your YETI lithium power station as additional power sources.
