Detail Comparison Generator Vs Inverter – Which One Is Best

Many homeowners are puzzled when deciding between an inverter and a generator for residential use. Although there is a distinction between an inverter and a generator, most people confuse the two and assume they are interchangeable.

Unlike generators, inverters convert direct current (DC) to alternating current (AC) (AC). Both may be used at home, but which is better, and what is the difference between inverter and generator, depends on a number of factors.

Along with the distinctions, which of the two is preferable? Do you really need an inverter generator? We’ll try to provide the most complete answers to all of these queries in this article, so keep reading.

Is A Generator Better Than An Inverter?

Generators make a lot of noise, but they can create a lot of electricity. They may be used to power up major equipment like fridges and ACs inside your home as well and their power backup lasts as long as you keep giving them fuel. They may, however, be big in form and take up a lot of room within your home, therefore they are usually hidden in places like under the stairs or inside the garage.

On the other hand, inverters are compact in form, easy to run, and most significantly, run extremely quietly to make them a desirable buy for residential users. They generate electricity by converting power stored in batteries and, as a result, turn it on as soon as the main power source is disconnected.

There is no need to restart manually. They come in a variety of styles to match the decor of your house, but they cannot support the weight of larger appliances. You may need to purchase a higher powerful inverter, which may be costly.

Generator Vs Inverter

First, we shall discuss Generator Vs Inverter. There are far too many factors to consider if you want to purchase the greatest power backup to help you the most. We’ve listed the key distinctions between generators and inverters to help you decide which one to use:

Generator Vs Inverter

Basics of Generator Vs Inverter

A generator is an electrical unit that provides emergency power for large power services or household electricity. A generator is essentially a device that converts mechanical energy from external sources into electrical energy. It is mostly used for electrical power distribution during a power outage.

Conversely, an inverter is an electrical device employed to turn direct current from sources like solar panels, batteries, or fuel cells to alternating current. It is a portable gadget that connects to a battery or a combination of batteries that attach to the device and power common household equipment.

Power Sources of Generator Vs Inverter

The engine is the major source of mechanical energy in a generator, and it is often powered by propane or gasoline. Larger engines for industrial uses, on the other hand, run on natural gas, diesel, or propane. One of the most common fuel options that increase the mobility of compact generators is gasoline.

An inverter, on the other hand, converts stored power into the conventional current. A grid-connected inverter transforms electricity from solar panels and wind turbines to alternating current (AC), which is more suited for long-distance transmission.

The Capacity of Generator Vs Inverter

Generators are large electrical devices that can bear huge loads and come in a variety of capacities. They are useful in areas with frequent power outages and are more resistant to strong power spikes. If the power spike is minor, it continues to run. Nonetheless, starting a generator takes some time and effort.

Inverters are medium-capacity devices that are appropriate for home usage since they have fewer power spikes. It has auto-shut capabilities that switch off the power in the event of a rapid power spike, preventing harm to the machine. Furthermore, inverters start automatically when the electricity is turned off.

The Maintenance of Generator Vs Inverter

Most gasoline or diesel-powered generators require routine maintenance such as oil changes, distilled water changes, lubricating oil changes, and so on. With proper management, gasoline and diesel have a shelf life of 12 to 24 months. Furthermore, unless a fuel stabilizing agent is used, gasoline cannot be deposited in substantial volumes for more than a few months. Generators also generate additional noise.

Inverters, on the other hand, require little to no maintenance since they use simple circuitry to convert DC to AC.

Difference Between Inverter And Generator

Principle Generator Invertor
Storage A generator does not store power; rather, once started, it creates electricity. As a result, it must be started first, and only then can it give electricity. When the utility supply fails, there will obviously be a time lag between the beginning and getting backup power. A power inverter set does store electricity in the form of direct current in the batteries (DC). During charging, it transforms alternating current (AC) from the mains and stores it before reconverting it to AC to power your appliances. There is no timer, and there is no manual start.
Energy A generator produces power. It is a mechanical device that uses spinning mechanisms to convert the calorific value of diesel into electrical energy. An inverter is solely capable of storing and converting energy. When DC power is turned into alternating current electricity, the outcome is a constant electrical signal. It has the same properties as a perfect alternating current when properly filtered.
Weight Unless you merely need backup power for residential lighting and appliances, a DG set can be heavy and big, needing a metal frame and wheels. They are technically portable, but they lack the convenience element. An inverter is not large or heavy equipment, but it can only function in conjunction with a set of linked batteries. These might be heavy and difficult to move.
Maintenance Generators create energy by burning diesel or gasoline. They need routine maintenance such as oil changes, lubricant changes, distilled water top-ups, and more. They also make more noise. Inverters help with maintenance. They don’t require much attention. Simply ensure that the water level is enough and that the battery connections are clean.


About – What is an inverter generator?

An inverter generator is a novel type of power source that has gained popularity in recent years due to its ability to provide clean, consistent AC energy without the necessity of sound-dampening enclosures. It is possible to configure this type to produce either 120 V or 240 V, and as you might expect, they are considerably quieter than traditional generators.

About - What is an inverter generator


Inverter generators produce electricity in three phases. They employ electrical circuits to convert electricity from a direct current (DC) source, such as solar panels or a car battery, into alternating current (AC). Direct current is abbreviated as DC. This means that electric current (charge) can only go one way. Alternating current (AC) is an acronym for the flow of charge that changes direction on a regular basis.


Inverter generators are substantially smaller, lighter, and quieter than standard generators. This sort of generator may be associated with the following activities:

  • Outdoor activities such as camping and boating
  • Lamps, heaters, fans, radios, cell phones, and other electrical equipment

Noise, Fuel Efficiency, And Power Output

Though inverter generators may not produce as much power as traditional generators, they are much more efficient due to the way the AC current generates energy. The generator is more efficient when less gasoline is used and the fuel tank is smaller. An inverter’s output power ranges from 1200 to 4000 watts.


An inverter generator is more portable than a traditional generator. They are lighter and more compact. If a product is light enough to be carried by its handle, whether it has built-in wheels is less important. This will also make storage between uses easier. Another issue that influences the weight and usage of these goods is fuel, which we will address later in this article.



One of the primary advantages of an inverter generator is its greater fuel economy. You can get more juice out of less fuel. This, in turn, reduces its weight and enhances its portability. It also makes these goods more ecologically friendly than conventional ones, which release more fumes.


Because of the new technology used and the additional benefits such as noise and economic efficiency, inverter generators are more costly.

When to Choose It?

Because of the more consistent output, an inverter generator is a good alternative if you’re operating sensitive gadgets like laptops, tablets, or cell phones. When compared to the fluctuating supply of a traditional generator, the continuous current is less likely to harm the electronics. The reason for this is that these models have far less harmonic distortion.

  • Electronic gadgets and other sensitive equipment, such as PCs and personal printers, are safer with an inverter.
  • It generates a clean sine-wave output that corresponds to the quality of the power source.
  • It makes almost no noise.
  • It does not pollute the environment or is environmentally friendly.
  • They can’t produce as much power as convential genarators produce.



Quality of power generated by the inverter generator

Because a generator is just an engine operating at maximum speed to create the required frequency regardless of load, the engine throttles up to maintain the same quantity of generated power.

The output of the alternator is supplied straight to the load without any processing. AC power is generated by inverter generators by converting direct current to alternating current.

DC capacitors smooth down the generated current to some extent before it is transformed into alternating current with the required voltage and frequency. Inverters provide steady and dependable electricity that is independent of engine speed.

The electricity supplied by an inverter generator is significantly “cleaner” than that provided by conventional generators. This power is nearly as good as the electricity you usually get from your utility provider.

How To Use Inverter Generator?

An inverter generator’s mechanics are slightly more intricate than those of a typical portable generator. More components are required to provide the final power output. Many inverter generators use fossil fuels as well.

In addition to drawing electricity from the gasoline tank, the inverter generator houses the battery, alternator, and inverter. The power flowing from the engine is a high-frequency AC current that the alternator converts to DC current.

The inverter then converts the DC currents back into AC currents. Inverter generators, like standard portable generators, produce 120 volts at 60 Hz. The current of an inverter generator, on the other hand, is significantly more consistent due to the additional processes in power generation.

How To Set Up Inverter In Home?

Connect the inverter / UPS to the outgoing of the main double pole (DP) MCB through a 3 Pin Power Plug and 3 Pin Power socket to the main supply to charge the battery. To connect the UPS to the main panelboard when in safe mode, use a 6 AWG (7/064′′ or 16mm2) cable and wire size.

Higher quality electrical parallel capability and output

Inverters automatically upgrade a generator’s technological capabilities. They generate electricity similar to that utilized in a house or residential environment.

Another advantage is that they may be paired with identical units for increased power output.

So, instead of utilizing a huge and bulky normal generator that generates a lot of noise, you might utilize two inverter-equipped generators to provide the same amount of electricity while being twice as efficient.

Why Are Inverter Generators So Quiet?

In terms of design and operation, traditional generators and inverter generators differ greatly. It reduces the noise produced by the inverter generator.

The first difference is the engine; the engine used in inverter generators is smaller and quieter than those used in traditional generators. Furthermore, they do not need to operate continually in order to maintain the frequency of the output voltage.

The inverter generator’s operation provides a consistent frequency. The engine drives the alternator, which generates AC power that is converted to DC and then back to AC. A microprocessor is used to control the entire operation.

When the load is low, the microprocessor reduces the engine speed, resulting in less noise while maintaining the same frequency.

One of the most significant advantages of inverter generators is the reduction of noise. All inverter generators are outfitted with superior noise-reduction technology and excellent mufflers.

Aside from that, the generator’s shell is built of noise-absorbing and high-quality material.


What Is a Conventional Portable Generator?

Conventional generators are the most common and have been around the longest. These engines are powered by gasoline, diesel, or propane. It works like this: the generator’s motor rotates an electric alternator, which transforms mechanical energy into electrical power.

The variability of the motor’s speed impacts the output in cycles per second or Hertz. This means that, if feasible, the rpm should be kept constant throughout the power generating process to avoid variations in power output.

This sort of generator is often loud, but it provides excellent dependability and may be used as a backup power source in emergency situations or when your home’s main power supply fails.

What Is a Conventional Portable Generator


Standard generators, also known as conventional generators, will be around for a long time and are currently the most commonly utilized machinery. A standard generator’s engine sends power to a motor coupled to an alternator in order to create electricity.


Because of the way the engine functions, conventional generators are noisier and produce more noise. Internal fuel burning produces the noise heard from a traditional portable generator. As a result, traditional generator operations are typically linked with job sites where employees need to power air compressors, nail guns, saws, hammer drills, and other equipment.

Noise, Fuel Efficiency, And Power Output

Conventional generators are powered by fossil fuels like diesel, gasoline, or propane. They frequently feature bigger fuel tanks than other generator kinds on the market, allowing them to run for longer periods of time with fewer refilling attempts. Conventional generators may provide more power than inverter generators due to engine sizes of up to 10,000 watts.


The fuel that your generator runs on has a direct impact on its mobility. A gallon of gasoline weighs around 6 pounds. Diesel, on the other hand, weighs little more than 7 pounds, and a propane tank might weigh anything from 4 to 10 pounds. As a result, the fuel type is a critical issue with these items. It also makes a built-in handle and wheels a lifesaver.



Another distinction between traditional and inverter generators is the latter’s newer technology. One of the most obvious disadvantages of a traditional generator is its inability to maintain a constant RPM. Instead, it varies, which is referred to in the business as harmonic distortion. It may be referred to as a shortage of clean power. It may not affect your power tools as much, but it can damage sensitive gadgets such as laptops.


In terms of pricing, conventional generators often have a lower initial cost and are more reasonable if you want a large amount of electricity.

When to Choose It?

When it comes to a flexible product with a high-power output, the traditional generator excels. As a result, it’s a fantastic alternative for contractors who want a dependable power supply on the job. It’s also a wonderful choice for a home emergency backup system. It has the necessary power while maintaining reasonable runtimes.

  • Conventional generators are enormous and heavy for a reason.
  • They have more fuel capacity.
  • With additional fuel, you can run a regular generator for longer periods of time without running out.
  • If you are running larger equipment and want a large quantity of electricity, use a generator that can produce 500 watts to 50,000 watts.
  • Long-term maintenance costs will be higher owing to wear and strain on moving parts.
  • Increased pollution as a result of the usage of fossil fuels.



Types Of Generators

Based on their performance, generators are classified into three types. They are as follows:

  • Conventional
  • Inverter
  • Solar

Conventional Generator

Both conventional and inverter generators work on the same basis. They employ an engine fueled by a fuel source to transfer energy from one form to another. In this example, it is mechanical to electrical. They do this utilizing an alternator, which is in charge of creating alternating current (AC) to power your equipment.

The framework for the conventional generator may be traced back to Michael Faraday’s discovery of the Faraday disc in 1831. The first fuel-powered versions followed, pushed by scientific improvements during World Wars I and II. It is the primary distinction between traditional and inverter generators. It immediately generates an alternating current (AC). Consider it the initial generation of modern-day electrical generating.

Inverter Generator

An inverter generator operates on the same principles as a traditional generator, but it takes a different path to its target. The running pace is one of the primary distinctions between the two types. A traditional model remains at its fixed location. An inverter, on the other hand, is more responsive to changing energy demands. This component is important in the primary principles we discussed with the former.

Inverter Generator

In 1965, Honda launched the latest technology of the inverter generator. It was a key development that made these items more accessible to residential homes. They solved the drawbacks of traditional generator operation, making them the favored alternative for many consumers.

Solar Generator

A solar generator is a device that transforms solar energy into electricity. This energy may be used to power electronics or appliances in your house. In general, solar-powered systems do not require any fuel, and there may be no need to add fuel during the usage period.

Can Conventional Generators Be As Quiet As Inverter Generators?

No, traditional generators cannot be made as quiet as inverter generators. As previously mentioned, their operating methods differ significantly.

Even so, you may lower the noise of a traditional generator to a certain level by using certain external techniques, but it will be more than that of inverter generators.

Even if you encase the whole generator in the casing, you will want air and exhaust ports. Simply said, exhaust pipes are the generator’s second most loud component.

Is diesel cheaper than gas?

Because diesel fuel is heavier and less volatile than gasoline, it is easier to refine than crude oil. As a result, in most nations throughout the world, diesel is less expensive than gasoline.

Buyer’s Guide for Generators

A generator is a major investment, regardless of whether you buy a traditional or inverter model. We recommend that you begin with your electricity requirements.

Consider the amount and types of power tools you’ll likely need if you intend to utilize them for DIY tasks. Calculate how much power you’ll need to power your RV or home’s appliances, lights, and electronics in the event of a power outage. Calculating the figures is essential for selecting a generator that will provide the best performance when you need it the most.

Other Factors to Consider

As you know, the type of fuel has a significant impact on numerous scores. However, we would recommend taking it a step further. Consider the availability of gasoline while boondocking vs a stationary emergency backup system at home.


Another key consideration is price, especially if the output is an issue. The traditional generator provides the commodities at a lower cost. However, inverter generators that enable parallel connections can provide greater power. This also adds variety to the equation. Depending on your power requirements, you can bring one or more devices.

Consider the whole cost of owning a generator. The inverter will take a bigger bite out of your wallet at first. It will, however, be more efficient. Similarly, while a traditional vehicle may be less expensive initially, it will cost more in gasoline and maintenance over time.


Of course, convenience is always an important consideration. Inverter generators are more portable, which might be a deal-breaker for an RV. They also require less upkeep than a traditional generator. However, if your location has regular power outages, it’s difficult to top a traditional generator’s extended run durations and ideal power.

Buyer’s Guide for Generators Convenience

Fuel also has a role inconvenience. If you just use your generator for fair-weather camping vacations, the fuel type isn’t as important. If you camp all year, propane is probably not the greatest choice for a primary fuel source. If you reside in a northern environment, you should use your generator as a backup.

Environmental Impact

A fossil-fuel-powered generator has an inherent environmental cost. Fortunately, the Environmental Protection Agency (EPA) in the United States regulates these goods for fuel efficiency and functioning. Many manufacturers have also chosen to comply with the higher California CARB-Compliant criteria, making them an even more environmentally responsible option.

Noise level difference between generator and inverter

The biggest difference between an inverter generator and a traditional generator, according to GreenGear worldwide, is noise levels.

Generators are often highly loud and produce power at continuous rates of 3600 rpm. To create energy, the engine speed should be kept constant.

Inverters, on the other hand, may use microprocessors to regulate the quantity of electricity generated.

This means the gadget can adjust its power output based on demand, making it quieter than generators.

Generators with inverters offer easier maintenance

Inverter generators are easier to maintain than non-inverter generators. You won’t need as much gasoline, which means less residue and a longer continuous operating duration. You will need to examine your battery once a year, but that is all.

You won’t have to repair your carburetor, fuel lines, or gaskets as frequently with an inverter-equipped generator. They also consume less oil.

Why are inverter generators so expensive?

Inverter generators are the next generation of portable electricity. Because they include inverter circuitry, they are a significantly better investment than a normal generator, whether for backup, camping, or getting off the grid.

Inverter generators are so costly because they are more efficient, consume less fuel, are quieter, lighter, and can give a better electrical current that is closer to the grid supply quality delivered to our houses, and they can be hooked up with other generators to deliver extra power if needed.

We will look at the numerous factors that make inverter generators superior to regular generators while also being more expensive.

  • The distinction between conventional and inverter generators
  • How inverter generators save fuel, reduce noise, and weight, and improve electrical quality
  • Why do contemporary household gadgets and devices require grid-quality power?

Even though they are more expensive, once you grasp the significantly higher performance and current quality they provide, you may never want to use a regular generator again.

When to Choose a Conventional Portable Generator?

  1. If you require a portable generator for an extended period of time.
  2. If you have a large number of powerful equipment.
