What is an Inverter Generator? Everything You Need to Know

The power's out and you're looking for a solution. While traditional generators have been used for ages as a reliable way to restore electricity to your home, inverter generators are the modern and probably the most effective home power backup solution. So, what is an inverter generator? An inverter generator is a modern type of power source that has recently become quite popular as it produces stable and clean AC power without soundproof enclosures. 

In addition, an inverter generator is quieter and more fuel-efficient than traditional generators. It is a portable generator with an electronic upgrade that automatically adjusts the engine speed to the current energy demand instead of running at a consistent speed regardless of the load size. This is what reduces the noise level and fuel consumption. 

In this guide, we'll answer the question, “what is an inverter generator” and tell you everything you need to know. 


What is an Inverter Generator & How Does it Work?

The dynamics of inverter generators are quite more complex than those of a conventional portable generator. More parts are involved in producing the final power output, and many also run on fossil fuels. Besides the power drawn from the fuel tank, inverter generators also have an inverter, alternator, and battery. The resulting power from the engine is a high-frequency AC that's changed into a DC by the alternator. 

The DC current is then converted into AC current again by the inverter. As with conventional portable generators, inverters generators can have an output of 120V at 60 Hz. However, because of the extra steps in power generation, the current from inverter generators is much more stable. This implies there are fewer harmonics distortions, which is why they produce clean electricity, equal to the quality of the power you get from your main power supplier.

In addition, the generated electricity is made clean because the AC current in an inverter generator is produced at a higher frequency, producing more electrical energy. Also, converting the DC current back to the AC current makes producing clean electricity possible. The dynamics and mechanics of inverter generators have more control over the AC frequency, producing a more stable sine wave. 

This greater control over the power output makes them quite energy-efficient. You can adjust the voltage as required for the connected load while maintaining an RPM of 3600. This steady current is also the primary reason an inverter generator is quieter than conventional portable generators.  

Benefits of an Inverter Generator 

Quiet Operation


Most inverter generators generate noise below 60 decibels, equal to a quiet conversation's volume. It also has a small engine that works steadier and slower, producing less noise than a traditional generator. Furthermore, they're made with a noise-reducing design that involves an enclosed casing and installed mufflers for sound insulation.

Fuel Efficient 

Inverter generators are more fuel-efficient than traditional fuel-powered generators. Unlike traditional generators, which work at a constant speed, the generator can automatically adjust the engine speed to only what's needed. Running the inverter generator at a reduced speed saves energy, requiring less fuel. 


Inverter generators are lighter than the common fuel-powered generators because of the small fuel tank. Most of them are designed with carrying handles or wheels for easy mobility. 

Clean Power 

The inverter generator's mechanical technology generates a sine wave that outputs fewer fuel emissions and much cleaner electricity than conventional generators. The high-quality electrical output implies a safer environment for the electronics and also because of the parallel capability.


Types of Inverter Generators 

Open Frame 

An open-frame inverter is a portable generator type that uses the open-frame design. This implies that the engines of the generator and other primary components aren't enclosed in housing as with the conventional portable generator. Open-frame inverter generators are cheaper due to their simple build, are less reliable, and can be more risky to use.


  • Easier to repair and maintain
  • Are more affordable than closed types
  • Less fuel-efficient
  • Can be noisier

Enclosed Frame 

Closed-frame inverter generators, as the name suggests, are enclosed in a metal housing. This casing makes them more weather-resistant and more durable than the open-frame models. They're also quieter, making them an ideal choice for tailgating or camping, and they usually have wheels and carrying handles for easy transport. They're also more expensive but are safer and more reliable. A good example is EcoFlow 1800W Dual Fuel Smart Generator (pictured below) with an advanced design and huge capacity for prolonged blackouts. 


  • More fuel-efficient
  • Are quieter than open-frame ones
  • It could be more difficult to maintain and remain
  • It can be more expensive to maintain and purchase

What to Look for When Buying an Inverter Generator 

There are various factors you need to consider when buying an inverter generator, including the following:


The first thing to look for when looking for an inverter generator is the size of the generator you need. They come in various sizes, so it's essential to go for one that can power all your devices. 


Depending on your power needs, you should go for a generator with the ideal wattage for your needs. Another factor is how long you'll need the generator to run, so if you require it to run for short periods, you should buy a smaller generator. On the other hand, if you need it to run for long periods, you should go for a larger one with a higher wattage. 

Noise Level 

Inverter generators are much quieter than conventional generators. So, if you are using your generator in a region where noise is a concern, you'll want to purchase a model that's as quiet as possible.

Price and Efficiency

Of course, the price of a generator is a crucial factor to consider. Inverter generators can range from a few hundred dollars to several thousand dollars. Therefore, it's crucial that you go for a model that's within your budget. In addition, you'll want to ensure your purchase generator is as efficient as possible. The more efficient your generator is, the less fuel it will use. 


If you need to use your generator on the go, you'll want to purchase a type that's easy to transport. There are various models, such as the Pulsar PG4500ISR 3700W Portable Inverter Generator with Remote Start and the EcoFlow Delta Max 2000 Power Station +1X 1800W Dual Fuel Smart Generator that have handles and wheels, so you should opt for one that's easy to transport.


An inverter generator is an efficient piece of equipment providing consistent and quiet electrical power to power the home during a power outage. You can power your inverter generators with propane, diesel, gasoline, or natural gas. It's increased in popularity in recent years due to the many benefits compared to traditional generators.

 These benefits include quiet operation, fuel efficiency, portability, and clean power. You must purchase one that best suits your needs to enjoy these benefits. When purchasing an inverter generator, consider the right size, portability, efficiency, price, wattage, and noise levels.
