Solar Generators vs. Gas Generators – What’s the Difference and Which is Best for You? 


Looking for a generator to power up your appliances and devices in the home? Is your choice a toss-up between a solar generator and a gas generator? Read on for a closer look at each of these types of generators, how they work, the differences between the two, and some fantastic options for you to consider.

What is a Solar Generator?

A solar-powered generator for the home is a battery system that uses collected solar power to charge appliances. It’s essentially a portable power station that utilizes solar instead of fossil fuels.
Solar energy is stowed away in the battery ready to be used when needed, turning DC electricity into AC power. A solar generator for the home will have multiple outputs to charge many devices simultaneously.
People have many uses for their solar generators, some of the most common uses are for camping, boondocking, home backup in the event of a blackout, and for general home or garage use.

What is a Gas Generator? 

A gas generator for the home is a system that burns gas or propane to help generate electricity. It’s traditionally used for home back-up in the instance of a blackout or more unconventionally, as a primary source of power if a home is too far away from the main grid source. Additionally, a portable gas generator works in the same vein as a heavy-duty outdoor one but will have a small capacity.

How Does a Solar Generator Work?

A solar generator collects energy using portable solar panels. It turns this energy into DC electricity. The power input is then regulated using a controller which is important for keeping the power stored safely. Whenever power is needed, an inverter converts the electricity into AC power, which is required for most appliances.
What’s great is that solar generators don’t need the professional skills of an electrician to install them in your home, they’re portable and can fit easily in your cupboard. They can be used safely indoors too.

How Does a Gas Generator Work?

A gas generator uses fuel to convert mechanical energy into electrical energy. A small gas generator for a house can be operated automatically or manually. If the gas-powered generator is used automatically, it will identify when there is a power cut and will run without the need to press a button, often called a backup generator. It then signals with a load transfer switch to swap the electricity from the home utility box to the generator. And vice versa when the utility power returns and only then will it switch off. The same can also be achieve with and EPS function on a solar generator, as found in EcoFlow models.

What are the Key Differences Between the Two?

There are a few notable differences between both solar and gas generators, which we’ve covered below:


Everyone wants to minimize their localized noise pollution, and choosing a quiet generator will give everyone a bit of peace. A gas generator tends to be loud, and the bigger the machine the louder it gets. A solar power generator is much quieter.


Gas generators use either gas or fossil fuels whereas a solar generator utilizes the light of the sun, among many other charging methods.

Outdoors vs Indoors

Most likely you’ll want to keep a gas generator outside because, well, fumes. With a solar generator, you can carry it inside without worrying about localized pollution affecting your health.


Refueling a gas generator is messy. With a solar generator, the only mess you have to worry about is whether you’ve accidentally tangled up the wire cable. Anyone can use them with ease, and without the need for any technical knowledge.


Both types of generators are portable depending on their size. All EcoFlow solar generators are designed to be portable too. The difference is that EcoFlow solar generators can be far more portable. A good example being the River 2, small enough to fit in a large backpack and light enough to carry with one hand. Even larger models such as DELTA Pro can be wheeled with ease.


While both generators for the home are safe to use, it’s more likely a solar-powered battery generator is a safer option than one that uses gas. Think of it this way – would you bring a gas generator into your living room space, RV or tent?
