7 Most Powerful Solar Generators (Buyers Guide)

If you’re looking for the most powerful solar generator on the market, you’re in luck!

Solar generators can be charged by solar panels, which convert sunlight into electrical energy. This energy is then stored in the solar generator’s battery for later use. Here’s the best part — this entire process produces zero carbon emissions.

Because they offer many advantages, solar generators are rapidly becoming a popular option for RVs, campervans, camping trips, and even as backup power sources for houses.

Depending on what you intend to power with a solar generator, you might be asking yourself, “Is there a powerful solar generator that can meet my power demands?

This article provides you with the 7 most powerful solar generators. Furthermore, we discuss what these powerful generators can power, whether they are safe, and how heavy they are.

What Are These Powerful Solar Generators Capable Of Powering?

A powerful solar generator requires an inverter with an output of at least 2000W.

Why? Because even though most common house appliances are rated with a low wattage (ranging from 10W to 200W), some power-hungry devices require up to 2000W or more power.

Air conditioner, hairdryer, clothes dryer, microwave, power tools, and coffee maker are some of these “power-hungry” appliances. They demand a high wattage (from 1300W to 2200W) to function correctly.

Each powerful solar generator listed in the previous section can power pretty much any appliance, even the high wattage ones.

The solar generators (from the listed previously) with the lowest Inverter rate are:

  • BLUETTI AC200 MAX: with a continuous inverter rate of 2200W
  • Point Zero Energy Titan: with a continuous inverter rate of 2500W (but recommended 1500W for 2 battery packs)

But even though they present the lowest continuous inverter output rate (among the previously listed solar generators), they are still considered powerful because 2000W is usually enough to power any essential or everyday appliances.

Are Powerful Solar Generators Safe?

This is a valid question you should ask before purchasing your solar generator.

The short answer is yes.


Overall

A powerful solar generator is very safe if you use it correctly.

Unlike traditional gas-powered generators, solar generators use sunlight as a clean and renewable energy source. Therefore, they don’t release toxic fumes, nor are they prone to flammable oil spills (or any other harmful substances).

Eliminating the need for refined fossil fuels (like gasoline and diesel) means eliminating several obvious safety hazards:

  • Firstly, handling these fuels is dangerous on its own. They can burn your eyes and skin, and breathing these noxious fumes can be very harmful to the human body.
  • Secondly, they are highly flammable (diesel less than gasoline), posing a fire risk.

By using solar generators, these risks are no longer a concern. Solar generators are easy-to-use devices that can be plugged into a wall outlet or solar panels to charge. They are maintenance-free and, unlike extremely noisy gas-powered generators, solar generators are quiet devices.

In fact, you can keep your solar generator inside your house, near your appliances, pretty much wherever you find convenient.

However, it’s important to note that, although solar generators are pretty safe devices, they can be quite dangerous if not used correctly.

Misuse of a solar generator can lead to electrocution, fires, or other injuries. It is therefore essential to read the instructions carefully and handle them correctly.


How Heavy Are Powerful Solar Generators?

Like most generators, solar generators are also a bit heavy, especially powerful ones.

Even though they are designed to be portable power stations, their large battery capacity makes them heavier than most people can comfortably carry on their own. For this reason, some models are equipped with wheels and handles to facilitate transport.

The weight of a solar generator depends on the battery chemistry (Lithium-ion batteries are lighter) and on the capacity (logically, the greater the capacity, the heavier the unit).

The table below lists the weights of the solar generators discussed earlier on in this article:

Solar Generator ModelWeight Of Main UnitWeight Of Extension Battery Module
BLUETTI EP50076 kg / 167.5 lbs——-
Hysolis MPS3K Power Station (and EXB-4500 Expansion battery pack)55 kg / 121 lbs27 kg / 60 lbs
EcoFlow DELTA Pro (and EcoFlow DELTA Pro Smart Extra Battery)45 kg / 99 lbs38 kg / 84 lbs
BLUETTI AC200 MAX (and B300 battery module)28 kg / 62 lbs36 kg / 80 lbs
EcoFlow DELTA Max (and EcoFlow DELTA Pro Smart Extra Battery)22 kg / 48 lbs38 kg / 84 lbs
BLUETTI AC300 (and B300 battery module)21 kg / 48 lbs36 kg / 80 lbs
Point Zero Energy Titan (and Titan battery pack)14.5 kg / 32 lbs36 kg / 80 lbs

As you can see, the heaviest solar generator on the list is the BLUETTI EP500; its 76kg (167.5lbs) weight is pretty substantial. Luckily, this model has wheels, making it easy to maneuver.

At 55kg (99lbs), the Hysolis MPS3K is also relatively heavy. Thankfully, a wheeled dolly is offered as an accessory.


What Battery Type Do Powerful Solar Generators Use?

Powerful solar generators use Lithium-ion batteries: Lithium Iron Phosphate (LiFePO4) and Lithium Nickel Manganese Cobalt Oxide (NMC).


LiFePO4

Often referred to as the safest and most efficient battery currently on the market, the Lithium Iron Phosphate battery (LiFePO4) offers the longest life cycle compared to any current battery technology.

LiFePO4 batteries offer a longer lifespan, are lightweight, require no maintenance, and improved discharge and charge efficiency — these attributes make them great candidates for solar generators.

Therefore, this type of battery (LiFePO4) is usually present in powerful solar generators (with large battery capacities).


NMC

However, due to its higher energy-density (higher than LiFePO4), some solar generators are equipped with Li-ion NMC (Lithium-Nickel-Manganese-Cobalt-Oxide) batteries.

NMC batteries are lightweight and can charge and discharge very quickly (with recommended DoD of 80% to 90%). However, these advantages come at a high cost to the battery’s lifespan — they can be discharged to a 20% state of charge and last up to 2000 cycles (LiFePO4 batteries usually last 5000+ cycles).

Another major issue with NMC batteries is the potential environmental contamination once they reach the end of their life cycle (the cobalt can enter the environment through improper disposal).


Examples

Powerful solar generators that use LiFePO4 batteries:

  • BLUETTI AC300
  • BLUETTI EP500
  • EcoFlow DELTA Pro
  • BLUETTI AC200

Powerful solar generators that use Li-ion NMC batteries:

  • Point Zero Energy Titan
  • Hysolis MPS3K Power Station
  • EcoFlow DELTA Max Portable Power Station
  • Goal Zero Yeti6000X
  • Goal Zero Yeti3000X

Final Thoughts

Power outages can happen anytime, anywhere. What’s more, they can last for several days. 

In these situations, solar generators can be a fantastic energy source option. They are versatile devices, very convenient, and easy to use.

The solar charging feature makes them environmentally friendly, and it’s possible to charge them even in extreme cases where traditional power sources aren’t available. After all, the sun will always shine.

However, during power outages, small solar generators are pretty much useless, as they can’t power high-wattage appliances that are essential (like a refrigerator).

Therefore, powerful solar generators are the most appropriate option for these situations. They offer a high power output, capable of safely powering many loads simultaneously. In addition, a powerful solar generator has a large battery capacity, providing power for a long time before you need to recharge it.

In this article, we presented the 7 most powerful solar generators. Hopefully, one of them will suit your needs.
