7 Best Solar Generators in 2022 Reviewed


The sun is among the best sources of energy at our disposal. It’s renewable, clean, and thanks to solar panels, it’s simple to capture and reserve. Solar power is especially beneficial if you’re off the grid, camping, or looking for the safest, most environmentally-friendly generator. 

A solar generator offers low running costs and no fumes. With one, you don’t have to worry about emitting hazardous toxins into the environment like you would with a fossil-fuel-powered generator. The benefits are clear, but choosing the best solar generator can be challenging unless you’re an expert. 

That’s where we come in.

We’ll go over the best EcoFlow solar generators in 2022 and what benchmarks to consider to narrow down your buying decision. Let’s get down to it! 

7 Best Solar Generators Reviewed

At EcoFlow, we develop portable power stations that keep on giving. Unlike gas-powered inverter generators, solar-powered generators use solar panels to get their fuel from the sun. 

They offer an excellent solution to obtaining short-term energy when the power goes out or charging up appliances while camping. 

Here’s how EcoFlow solar generators work:

  1. They convert sunlight into direct current (DC) electricity.
  2. They store this solar energy until needed.
  3. They power your devices by turning DC into AC power.

It’s that easy! However, don’t assume that all solar generators are the same. They range in running watts, peak power, recharge times, etc. 

Below, you’ll find the top portable power stations in 2022. We’ll leave no stone unturned, covering each model’s features, specifications, pros, and cons.

What To Consider When Buying a Solar Generator 

Whether you need a solar generator for camping, tailgating, or power outages, different devices will serve you better in specific situations. Here is what you want to consider when buying a solar generator: 

Running Watts 

Also known as rated wattage, the running watts indicate the electricity the unit can produce continuously. To find a solar generator that covers the devices you need to charge, tally up the wattage amounts for each device. Include your smartphone, tablet, laptop, power tools, appliances, etc. 

Have your total wattage amount? You’ll need a generator with a running wattage greater than your total. 


Next up is watt-hours (Wh) or capacity. 

The Wh of the generator will determine how long a device can be powered. This measurement explains the length of time it can offer continuous power for 60 minutes at a full battery charge. 

It will also help you determine how much power the solar generator can offer before it’s time to be recharged. 

Peak Power

Also known as the starting wattage, the peak power output refers to the power the solar generator will need to provide before settling into the running output. This measurement is higher than running watts, but most devices only use it briefly until it settles down to running watts. 

This brief surge of power is necessary to power up an electric motor on devices like refrigerators or fans. Therefore, if you plan to power a device with a motor, you’ll need to determine its starting wattage. Then, be sure the peak power or starting wattage can accommodate it. 

Battery Type 

Your generator will require two main types of batteries: lead-acid or lithium-ion (Li-ion). Units with lead batteries will be cheaper than those with Li-ion batteries. However, Li-ion batteries will last longer and tend to be lighter. The duration and weight are essential if portability is a top consideration. 

At EcoFlow, our generators all use lithium-ion batteries. This choice offers four main benefits: 

  • No fuel necessary (say goodbye to toxic fumes)
  • No maintenance required
  • No lost power
  • Low cost (users will spend 30% less when compared to regular gasoline-powered inverter generators)

Recharge Time

How long will it take to recharge your solar generator? The time length is known as the recharge time. 

Visit the user manual to learn how long it takes to get your generator battery to a full charge. The time depends on the charging speed of the solar generator and the solar power it’s receiving. Typically it should take less than 48 hours, but larger units will take more. 

Also, factors like the size of the solar panels and the amount of sunlight they receive will affect charging times. If the weather is cloudy, charging time may take longer. Opt to charge these devices in direct sunlight for the best results. 

EcoFlow offers extremely fast charging technology. Expect your generator to charge from 0% to 80% in less than an hour.


Are Solar Generators Worth the Money?

In short, yes. Solar generators are worth it because there’s no telling when your home will experience a power outage. Intense storms and winds can knock power out for hours, even days. 
Plus, if you enjoy the great outdoors, a portable power station will enhance your experience. A portable solar generator can keep your devices charged and power even small appliances.

How Long Will a Solar Generator Last?

Rest easy knowing a solar generator will last between 25-35 years depending on brand and quality. 

What Size Solar Generator Do I Need?

The best size solar generator is the one that is reliable for your needs. The best solar generator for you will depend on the following: 
• Running watts
• Watt-hours 
• Peak power
• Battery type
• Recharge time
Think about your intended use. What devices do you want to power? If you only want to power small appliances like your phone or laptop, a generator under 1,000 watts will do. 
For larger appliances like your microwave or refrigerator, go with a generator between 1,000 to 3,000 watts. 
And, to power an entire house, you’ll want a generator with over 5,000 watts of power. 

Can a Solar Generator Power a House?

Absolutely! The right solar generator can power an entire house or off-grid cabin. 

Are Solar Generators Noisy?

Solar generators make no noise. Unlike fuel-powered units, you will enjoy a quiet experience when using a solar generator. There aren’t any moving parts with solar units, and the only noise you may hear will come from the inverter. Even then, it’s minimal. 


A solar generator can be a lifesaver if the power goes out. It does not require fuel and is powered directly by the sun. It’s quiet, suitable for indoor and outdoor use, and powerful enough to power an entire house. At EcoFlow, our portable power solutions offer fast charging, renewable charging, and all-around convenience.
