You are probably here for the same reason other people are out on the power supply market - searching for a reliable generator. However, when shopping, the sheer mass of information around such a product can be immense. It can make it difficult for you to choose the right one, especially if you are new to this game.

Thus, we take a look at the main facets of the inverter generator vs. regular generator.

There are few factors you have to consider surrounding these power supply units. These include efficiency, noise, emissions, and more. So, let us get started:

You probably have a basic idea of what a generator is, and probably it's just information on what it is. To begin with, let us take a look at a few key variants in these power supply units. Since you can use them for the same applications, many prospective users tend to be confused about their functionalities.

The main variance between these two is that an inverter generator works electronically to rev the engine up and down. It does this to help meet the given power demand levels. It's different from the traditional generator that operates full throttle the entire time.

The benefit of such a system is that you won't have to top up the tank conveniently regularly. Plus, inverter generators are also famous for producing a small amount of emissions, and they are also usually quiet.

Remember that "ALL" generators will produce alternating current, commonly referred to as A/C power. It occurs by converting mechanical energy into electricity. The portable generators often feature an engine, which operates on fuel such as propane, diesel, or propane.

The engine functions by rotating a mechanism referred to as an alternator, which produces the A/C. The engines burn the fuel, which powers an alternator, to produce alternative electricity, or alternating current (AC). It's the type of electricity that utility companies often deliver to residential and commercial setups.

A power inverter is an electronic technique of producing AC through a Direct Current. The inverter gets its power from a source such as a solar panel or battery. Plus, such systems feature a unique electronic system to convert the DC back into AC. Many electrical experts commonly refer to this process as inversion.

When the generator converts the DC power into AC electricity, it often leads to an unstable electrical signal. When filtered the right way, such electricity has the same characteristics as alternating current. Plus, the electricity is also safe for electronic devices and any other sensitive tools you may have.

Inverter vs. Regular Generator - Differences Defined

Below is a review of the key differences you can expect between these two common types of generators. You will realize that there are secondary and mechanical differences, which influence these power supply units' expected functionality.

A few things to expect include:

1.Current

The critical technical variation in inverter and conventional generators relates to the type of electricity they produce. The traditional generators can produce AC only, but the same cannot be said about inverter generators. These types can produce electricity in three stages: unstable AC to DC and then back stable AC.

The ability to produce a stable sine wave of energy is the most unique aspect of these generators. These are features that ensure they can provide clean electricity. Plus, they are also less likely to produce harmonic distortion, so they are generally safer for your devices. These include devices such as tablets, laptops, and more.

In comparison, a traditional portable generator is likely to produce a messy sine wave, which can produce lots of harmonic distortion. While it's still a unique power source for various devices, the types that have microprocessors should be used with caution. The main reason for this is because this type of current is not always stable.

2.Power and Fuel Efficiency

The traditional generator can produce more power than an inverter generator. The main reasons for this are many. A good example would be the fuel tank size and the mechanical variations that occur in producing electricity.

Usually, inverter generators are efficient due to the way they produce the final AC. Such generators feature engines, which adjust automatically to the load, which a traditional power supply unit can not achieve.

The fuel efficiency of such a generator means that one can use it with small fuel tanks. The high levels of efficiency mean that the machine will require less fuel so that that tank can be small.

The same concept does not apply to traditional generators. They are not fuel-efficient, so they tend to be bulky, primarily due to their large fuel tanks. The benefit of such a large tank is that it provides a better power output.

The difference in power is a critical distinguishing aspect between these types of generators. Where a traditional generator can provide between 1000 to 4000 watts, a regular generator can provide 12,000 watts.

3.Portability

On average, expect inverter generators to be more portable than your regular fuel-powered generators. Again, such a variation relates to the amount of power these units can produce.

Inverter generators tend to be more portable than the traditional fuel-powered types. Usually, this relates to the amount of power that these units can provide.

A traditional fuel-powered generator that produces more power might feature a large engine and tank. Thus, you may need more resources to house such a power supply unit. It's the main reason why traditional generators tend to be heavier and oversized than their traditional counterparts.

To provide added portability, the big conventional generators feature handles and wheels for easy pulling. While this might be a convenient feature, these generators tend to weigh over 100pounds.

Inverter generators tend to be smaller because they have small fuel tanks and won't require big engines because they provide relatively low amounts of power. Such designs help reduce a lot of weight, so such generators are not easy to carry using handles.

4.Noise

Many people know the traditional portable generators produce lots of noise when in operation. Such an aspect relates to the mechanics of such power supply units, and so expect to find ways to control the noise.

The technology that inverter generators feature means they can operate quieter. Research has shown that these generators operate at a stable 3600rpm, which is why they are exceptionally silent.

The amount of noise a power supply unit will produce usually sits on the product description. Most brands will provide information on the decibels the generator will produce at a specific load.

Expect generators to produce between 50 - 58 decibels of noise. Such an amount is far much quieter than what one can expect with traditional generators that provide 64 decibels.

5.Parallel Connections

Brand companies often try to make up for the low power output of inverter generators. They do this by setting up parallel connections for convenience. The parallel connections let users connect two inverter generators to provide extra power.

However, the portable types don't offer users the ability to parallel connect two units. It's not a surprise considering they are already small and less portable.

6.Emissions

Each state has specific regulations relating to the use of generators and the production of greenhouse gases. These laws can be stricter when you want to use a generator in parks or even campsites.

Usually, a portable generator should be EPA compliant, with states such as California demanding CARB compliance.

The inverter generators produce a smaller amount of greenhouse gases than the traditional fuel types. It's easier to come across one that meets various environmental regulations than finding a regular generator that does.

7.Price

Usually, a traditional generator is more affordable than the inverter types. The conventional generators are pocket-friendly, especially if you require lots of power.

The main reason for the immense cost of inverter generators is because they are still relatively new. They consist of technologies that provide silence, excellent fuel efficiency and offer clean electrical current. Plus, traditional generators are simple tools that have been available for many years - a key reason behind their relatively low price points.

When to Choose an Inverter Generator

There are various benefits of inverter generators when compared to the traditional portable types. These include the fact they are compact, fuel-efficient, and suitable to use with your sensitive electrical tools. Plus, they also don't produce emissions, which is among some of the common issues associated with traditional generators.

However, these generators' main drawback is that they tend to be more costly than any similar traditional generator. Based on these benefits and disadvantages, an inverter generator is only ideal for occasional use and activities such as camping. Plus, an inverter generator is perfect when you don't require lots of power, but you can carry it around when you need clean electricity.

What Next Now That you Have the Right Generator

Now that I've chosen Standard or Inverter, how do I know how much power I need?

While this seems like a challenging thing to do, it's a convenient process.

All generators have ratings based on watts output. You can find out the wattage required in various ways.

The simplest method would be for you to determine the rating of a given product using the manual. Plus, a 100-watt light bulb will require a 100-watt power output from the generator. So, if you were to run three of these lights, you would need 300 watts of power.

What happens when I want to buy a power wrench and it does not have the power metric indicated on it? Well, most products today have electric motors, that list details on amperage and more. You can use these metrics to determine the amount of Watts the device needs.

Use this formula: Voltage x Amperage = Watts.

Since you have 10 Amp power wrench through label or details listed on the devices, the formula should give these results

120V X 10A = 1200 watts.

However, remember that generators often have varying watt ratings, so which one would be best?

Well, this is easy because the running watts will determine the size of the generator that will be suitable for your needs. If you know you will be maxing out your power supply unit, consider a bigger version.
