What is an Inverter Generator

An inverter generator is perfect if you want cleaner and safer power for your electronic appliances. 

How does the inverter generator differ from your conventional generator?

A conventional generator uses a mechanical alternator to offer alternating current (AC) power. The power is ready to use on your appliances. On the other hand, An inverter generator uses an inverter to convert direct current (DC) into alternating current (AC). The main advantages of using an inverter generator are that it is more efficient than a conventional generator and produces cleaner power. Inverter generators are often used to power sensitive electronic equipment such as computers and TVs.

Additionally, instead of running constantly, an inverter generator throttles its engine depending on the demand. 

The result?

  • Enhanced efficiency due to lower fuel consumption
  • Less noise
  • Reduced emissions

What is an Inverter Generator?

It’s a generator that inverts raw power to match the power you’d get through power lines. 

It electronically adjusts the engine’s speed to meet the demand. Instead of keeping the engine operating at maximum power all the time, the generator adjusts to power demands. 

Its improved performance ensures you can go longer between fill-ups. These generators also decrease the amount of noise pollution.

Inverter generators have recently gained popularity because they can reliably produce clean, constant AC power without requiring a soundproof enclosure. 

They can alternate between producing 120 V and 240 V and are much quieter than their counterparts.

How Does An Inverter Generator Work?

An inverter significantly modifies the operations of a generator. The rectifier converts the alternating current (AC) from the alternator to the direct current (DC). 

The microprocessor inside the generator converts the DC power back into AC before sending it to the control panel. An inverter is a term derived from changing the current type continuously. 

The Total Harmonic Distortion (THD) is drastically reduced in inverter generators compared to conventional ones due to the computerized regulation of electricity to the panel. 

When thinking about how to power sensitive electronics like smartphones, tablets, PCs, and TVs, THD should be a top consideration. Clean power or power with a low THD is essential for these devices. 

These gadgets are vulnerable to high-THD power. Since they all use pure-sine-wave inverters, inverter generators can reliably maintain THD at or below 1%. 

Conventional generators’ THD can reach 25% in extreme instances.

Regardless of whether the electricity has passed through a voltage regulator or other safety devices. THD indicates how clean the energy is.

.What Is An Inverter Generator Used For?

The inverter generator includes a battery, an alternator, and an inverter, in addition to the fuel tank. 

The alternator converts the high-frequency AC power produced by the engine into the lower-frequency DC power used in the generator. Once the inverter receives these DC currents, it converts them into AC currents. 

Similar to standard portable generators, inverter generators output 120 volts at 60 hertz. An inverter generator produces more consistent electricity due to the additional processes involved.

Inverted generators are typically used in applications where weight and size are critical. They can be used in various applications, including powering portable electronics, providing backup power for homes and businesses, and even charging electric vehicles.

What Are The Advantages Of An Inverter Generator?

Why should you go for an inverter generator instead of a conventional one?

Reduces fuel consumption

Inverter generators are designed to reduce fuel consumption while providing the necessary power. Traditional generators can waste fuel and produce harmful emissions, but inverter generators are up to 80% more efficient. This means that they use less fuel and produce cleaner power that is safer for the environment. 

A standard generator has only “on” or “off” as a command. But an inverter can automatically adjust its output in response to the power needs of your connected gadgets. 

Therefore, the inverter generator saves money on gas. This feature makes it the greenest option available.

The Inverter Generator Will Protect Your Sensitive Electronic Equipment.

Inverter generators run cooler than traditional generators. This is because inverter generators convert DC power to AC power, producing less heat, so they don’t overheat and damage sensitive electronic equipment. 

Easily Portable

Inverter generators are an excellent choice for those who need a portable and lightweight option. These generators are typically smaller and quieter than traditional generators, making them ideal for camping, off-grid living, tailgating, and other recreational activities.  When choosing an inverter generator, consider the wattage you need to power your desired appliances or devices. Most models have various wattage options to select to find the perfect size for your needs.

Cleaner Electricity

Inverter generators produce cleaner electricity than traditional generators. This is because inverter generators have a higher frequency than traditional generators, which results in less electrical noise. In addition, inverter generators are more efficient than traditional generators, meaning they use less fuel and produce fewer emissions. 


One of the most significant advantages of inverter generators is that they are much quieter than traditional generators. This is because inverter generators use a different type of engine that runs at a lower RPM. 

Easy to Maintain

The only regular upkeep is a monthly check of the battery to ensure it’s still holding a charge.

What Are The Disadvantages Of An Inverter Generator?

Inverter generators are more expensive than standard portable generators. Although the unit’s up-front cost may be significant, its many advantages usually compensate for the original investment.

Inverter power generators are less potent than larger conventional generators, with outputs in the mid-to-low-thousands of watts. A simple inverter generator can power modest household appliances, RVs, and garden tools. If extra power is required, the inverter generator can run in tandem with a second generator.

Because of their limited output, inverter generators cannot supply conventional air conditioners or high-demand electrical loads. You’ll need a standard generator to power larger appliances or a whole household.

Inverter generator Vs. Standard Generator



It is gasoline or diesel-powered  Powered by batteries and converts the stored power into standard current
It uses external sources to produce mechanical energy, converting it into electrical energy. It is a device that converts direct current from storage elements like batteries, fuel cells, or solar panels and turns it into alternating current.
It requires effort to start a generator in case of a power outage It starts automatically immediately after the power fails without any gap in between
Mostly come in high-watt capacities They are primarily low-capacity devices
They demand regular maintenance and checkups. They are very reliable and require little to no maintenance.
They are suitable for high-power needs. They are suitable to power small appliances and gadgets

Inverter or Generator, Which Is Best For Home Use?

There are a few key factors to consider when deciding whether an inverter or generator is best for home use. One crucial factor is the cost of each option. Inverters typically cost more than generators. Another critical factor is the amount of power that each option can provide. Regular generators can provide more power than inverter generators. Finally, the noise level is another critical consideration. Inverters tend to be much quieter than generators. Based on these factors, it is clear that inverters are the better option for home use.
