What Is An Inverter Generator: Working Rule, Pros And Cons

What Is An Inverter Generator: Working Rule, Pros And Cons

If you do not like the hassle of power cuts, then reliable power backup solutions are the only option. However, it would be an added advantage if the power backup solution is portable. With the advent of sophisticated electronics and inverter technology, we now have inverter generators. But what is an inverter generator? If you are looking for an answer to this question, then stay with us and keep reading this article.

What Are Inverter Generators?

An inverter generator is a type of portable generator that uses an electronic alternator to produce electricity. Inverter generators use advanced technology to convert direct current (DC) power produced by the engine into alternating current (AC) power, which can be used for various household appliances or tools. It is designed to generate clean, stable power in order to make the most efficient use of fuel and minimize emissions.

How Does An Inverter Generator Work?

The inverter generator’s working is a step-by-step process which is listed below.

  • The fuel (gasoline) is used to run the engine which in turn rotates the alternator.
  • The alternator produces AC power which is full of distortion and is not usable at this point.
  • The AC power so generated is sent to the rectifier circuit which converts it into DC power.
  • In this step, the DC power is then transferred to the inverter module which converts it back to AC. The AC power thus generated is clean and free from distortions.
  • Finally, the power is available to use via the generator's outlets.

Pros and Cons of An Inverter Generator?

Inverter generators have their pros and cons which are discussed below.

Advantages of an inverter generator

  1. Low Fuel Consumption: An inverter generator does not need to run at 3600 rpm all the time to produce AC power. The engine speed auto-adjusts to the power drawn by the connected load. If the load is less then the engine will run at a lower speed resulting in less fuel consumption. On the other hand, conventional generators operate continuously at 3600 RPM, regardless of the power drawn by the connected load.
  2. Clean Power: The AC power produced by an inverter generator is free of harmonic distortion and is safe to use with small electronic devices. The output form of AC power is pure sine wave which is not known to harm household appliances and sensitive electronic equipment such as medical devices.
  3. Parallel Operation: If one inverter generator is not sufficient to meet your power demands, you can combine several of them to achieve the desired power output. This is something that is not possible with conventional generators.
  4. Portability: Inverter generators for sale are mostly small and easy to carry to places. Their portability makes them an ideal power backup solution when camping. For example, the Anker SOLIX F1200 Portable Power Station. It weighs an impressive 19.95kg with a 1229Wh capacity and 1500 wattage - making this powerhouse perfect to power all your devices and appliances during any excursion.
  5. Quiet Working: Because the generator operates at variable speed, it is less noisy than a conventional generator. The noise levels are acceptable and won't bother you during your camping vacation.

Disadvantages of an inverter generator

  1. High Cost: Compared to conventional generators, the cost of inverter generators is high. This is because they equip complex designs and circuitry with efficient inverter technology. But trust us, inverter generators are worth every penny that you spend on buying them.
  2. Low Power Output: The power output of an inverter generator is much less than that of a typical AC generator. But still more than enough for common household electronics and small appliances.
  3. strong>Not Safe Indoors: The inverter generator uses gasoline to run its engine. So, it will exhaust gases such as carbon monoxide. Using it indoors is not safe.


Now you know what is an inverter generator. Inverter generators are a great choice for people who need reliable, clean, and quiet power. They are fuel-efficient, portable, and can be connected in parallel for increased power output. However, they come with some drawbacks such as high cost, low power output, and not being safe to use indoors. Nevertheless, if you’re looking for a reliable, efficient, and environment-friendly generator then an inverter generator is the best way to go.

FAQs on What Is An Inverter Generator

What is the difference between an inverter generator and a regular generator?

What's the difference between inverters and generators? Let’s see the inverter vs generator comparison in 5 aspects:

1. An inverter generator is typically smaller and lighter than a traditional generator.

2. The inverter generator produces cleaner power, providing a more consistent voltage with less fluctuation. This makes them safer to use with sensitive electronics like laptops or cell phones.

3. Inverter generators also tend to be quieter and have longer run times than regular generators.

4. The inverter generator is also more expensive than traditional generators, but their superior performance often makes up for the difference in price.

5. Inverter generators go a step further than regular generators and convert the AC power into direct current (DC) with an alternator before it passes through a microprocessor which then converts it back to cleaner AC energy.

Why do you want an inverter on a generator?

Because we now live in an era full of electronic devices having low power requirements. The inverter technology ensures that the generator consumes less fuel and is safer for power-sensitive electronics. Inverter generator is highly suited for TVs, laptops, desktops, phone chargers, refrigerators, etc.

Can an inverter generator run a refrigerator?

Yes, most inverter generators can provide enough power to run a refrigerator. Generally speaking, an inverter generator with at least 2 kW of output should be able to handle this task without any issues. For example, a simple 360-watt refrigerator can run for 3 hours on a 1500 watts inverter generator.
