If you want to enjoy the luxury of dual-fuel capability in your inverter generator, then you should check out the Westinghouse iGen4500DF dual fuel inverter generator.

There are barely 3-4 inverter generators are on the market that comes with dual fuel capabilities. As you know, there is no generator that comes with only a propane fuel setup, but instead, it comes with a gasoline setup too, so that is why it is called the dual fuel generator.

It’s true that the initial cost of this generator is very high, but as you know, propane is very cheap and fuel-efficient compared to gasoline. So by using propane in your generator, you will save a great deal of money on fuel costs.

If we talk about the power output, then on gasoline, you will get 3600 running watts and 4650 starting watts, and you will get 3240 running watts and 4180 peak watts using the propane. I really like its digital display using which you can keep close tabs on fuel level, power output, remaining runtime, and so on.

This generator is extremely quiet, and in fact, it barely produces any noise up to 52 dBA, which is equal to the noise of a vacuum cleaner. It has a 3.4 gallons fuel tank, and the generator will give you about 18 hours of runtime on a fuel gas tank.

And you can increase this runtime by using 20 pounds of the propane tank and this also eliminates the need for frequent refueling.

Some people may find this generator to be expensive, but it has so much to offer, and trust me, it’s worth your money.

  1. It features three starting methods; remote start with an included key fob, electric start and recoil start, and let’s not forget its pure sine wave power output.
  2. Inverter generators are new in the market, and they are very complicated.
  3. The inverter generator is the same as the conventional generator, but the only difference is how it produces power.

First, it produces the AC power as all the normal generators do, but then this power is converted to DC and then it is inverted to AC power to create pure sine wave power.

The inverter generator has many advantages as well as disadvantages too, but in the end, it is worth every penny. The terms like generator, power inverter, and inverter generator are common, but there are big differences between those machines and their functionalities and design are entirely different.

Well, to know why inverter generators are so special, first, we need to understand the difference between an inverter generator and a normal generator and then we will discuss its advantages and other features. The fuel is ignited in the chamber and with the help of mechanical gears, the engine drives the alternator, which in turn produces electricity.

1. Best-Rated Inverter Generator—Champion

The generator has to run at a constant speed to produce the 60Hz frequency current. And due to load fluctuations, the speed of the generator also fluctuates; thus, its power output contains some harmonics, and it is a modified sine wave.

The inverter draws the power from a DC source, such as a battery or solar power, and converts this power into AC with the help of MOSFETs (Metal Oxide Semiconductor Field Effect Transistors) and to make the output current pure sine wave the bank of capacitor and inductor is used.

The Inverter generators are new generation machines that are equipped with advanced technology and some mind-boggling features. The inverter generator produces AC current, and then with the help of a rectifier, it is converted to DC, and then the inverting circuit again converts this DC power back to AC power.

The final AC power is a pure sine wave and it contains fewer harmonics, and thus inverter generators are safe to run sensitive electronic device which uses a microprocessor and other delicate circuits.

The inverter generators have made life a whole lot easier. It is a handy machine for those who like clean and stable power output (which contains less THD) and using this generator; you can easily run sensitive electronic devices such as modern TVs, smartphones, laptops, tablets, gimbal, and much more.

This generator is also useful for people who don’t like noise, such as when they host a party, or camping, or living in a neighborhood where noise is restricted.

4. Best Inverter Generator with Electric Start—WEN

Other than that, RVers also love the inverter generator because of its convenience and high-end features. Not sure why you should choose the inverter generator over a conventional generator; read this and know what is best for you.

As you know, almost all the inverter generators are compact and portable because they are designed to be that way; however, there are some exceptions. As the wattage rating increases, be it a conventional generator or inverter generator, the size of the generator is definitely going to increase.

Inverter Generator—Buying Guide

But still, the inverter generators are substantially portable and lightweight than any normal generator on the market. Any typical inverter generator rated below 4000 watts will max out at 80 pounds and but most of them are still lighter.

In all of them, the open frame style inverter generators are heavy, but on the other hand, they deliver great power output, so it is a great trade-off.

The inverter generator uses a combination of the advanced load monitoring system and inverter technology that adjusts the power output according to your power requirement, which makes it very fuel-efficient.

You will not get these features in a conventional or non-inverter generator.

Noise output is the biggest difference between the inverter generator and a conventional generator. Any inverter generator will produce about 50 to 60 decibels of noise at max, whereas the conventional generator will produce 62-70 decibels of noise, which is considered to be loud.

If you are not familiar with levels of noise, then first you need to know how many decibels can be loud for you. As the load increases, the rotor tries to keep up with the load, and in the process, the speed of the rotor fluctuates, which results in lots of dips and surges in power output.

Thus the power produced by any non-inverter generator consists of modified sine waves. But in the case of an inverter generator, it produces clean and stable power, and the reason is its inner workings.

Parallel capability is a pretty common feature in all inverter generators.

Suppose you want a portable generator for outdoor activities, but sometimes if you need more power, then buying a big generator is not an option. At that time, you can connect another same generator in parallel with this inverter generator and double the power output.

So it is a very convenient feature which you will never see in other generators. It goes without saying that you should be equipped with all the necessary information and factors you need to take into account before choosing any inverter generator.

Consider the following factors, and you will be good to go. The selection of the generator solely depends on where you want to use it and on your power requirements.

And depending on these factors, the size of your generator and power output can be decided.

Home Back-up System: If you want to use the inverter generator for powering the appliances of the whole house, then you need a generator with high power output.

You can consider a generator above 5000 watts and as a matter of fact, we have included one such generator in this guide so don’t forget to check it out.

RVs and Tailgating: RVs do have many onboard electronic devices such as AC, refrigerator, sump pump, TV, and so on. And to power all these devices at once, you would need a generator of at least 4000 watts of power capacity, and you can increase power by connecting two or more inverter generators together.

3. Best Inverter Generator Dual Fuel—Champion

Camping: For camping, you don’t need a big generator because in the middle of the jungle you don’t need much electricity.

So any generator between 1000 to 3000 running watts is sufficient for you. And also the generator for camping needs to be very quiet as you don’t want to disturb fellow campers and animals.

Most of the inverter generators have a small fuel tank and that is why their runtime is relatively lower. So if you don’t like frequent refueling of the generator, then I would suggest you choose the dual fuel inverter generator which we have added in this guide.

6. Best Inverter Generator 2000 Watt—Westinghouse

By using a high-capacity propane tank, you can increase the runtime, and also it eliminates the need for refueling again and again. In the case of inverter generators, the portability and power output seem to be opposite of each other, here’s how.

Inverter generators are indeed portable, compact, and lightweight, but as their power output increases the size and weight of the generator also increases. So it depends on what you want; a portable and lightweight generator with low power output or a bulky and heavyweight generator with high power output.

There is no denying that the inverter generators are the quietest generators among all the generators; however, the noise output of one generator can differ from one machine to another machine.

Meaning that the generator from one manufacturer can be loud but the generator from another manufacturer can be quiet.

Better safe than sorry; so that is why you should check the noise output of your selected generator.

It is not a game-changing factor, but still, you should keep this in mind.
