An Inverter Generator is a more sophisticated electrical tool compared to those regular generators.

The conventional generator produces one block wave of AC power per each engine rotation. For the conventional generator to produce standard US electricity of 120-volt and 60-Hz, the engine should operate at a constant speed of 3,600 rpm.

It can keep your whole house running if there is no electricity for several hours without damaging your TV or a Fridge. As you might be knowing, the inverter generators provide more efficiency and run smoothly and more quietly while providing the cleanest power than any non-inverter generator. So, you can charge or power your sensitive electrical equipment without reducing its lifespan or causing electrical-heating in it.

Now, let’s see how this inverter generator works. Before we tell how an inverter generator works, first let us understand how conventional or non-inverter generators work.

The inverter generator, as well as conventional generators, both use gasoline or diesel engines to generate a rotary motion.

The mechanical energy of this rotary motion is converted into electrical energy by a principle called electromagnetic induction. This induction process produces a voltage and frequency of 120 V and 60 Hz; this is a standard rating that is available at every electrical outlet of any house in the US.

Almost all domestic appliances and equipment are designed to work satisfactorily with this voltage and frequency value. So to keep them working, the same power needs to be supplied. The conventional generator must run at a constant speed (3600 RPM) to constantly supply the power of 120 volts and 60 Hz frequency, which means it consumes the same fuel even if the load is less.

So, Which is The Best Inverter Generator?

This is because the induced voltage and frequency obey the formula given below. Here, N is the engine’s speed that it needs to maintain, f is the frequency of the generated voltage, and P is the number of poles in the rotating mechanism. The number of poles is 2 for household generators. Here our main concern is the frequency and the speed.

As mentioned, all equipment works satisfactorily at 60 Hz-120V, and to generate 60 Hz frequency, the speed must be constant. Let’s take the number of poles to be 4, now; to continuously supply the frequency of 60 Hz, the speed of the generator needs to be 1,800 RPM regardless of the load. That’s where the inverter generators differ from the conventional generators in the mechanism to supply this needed power. The inverter generator produces the electricity in the same way, but it has some extra mechanism that gives it an edge over conventional generators.

Wattage Demands of Inverter Generators

In an inverter generator, the AC electricity is generated due to the induction phenomenon, which is then converted to DC, and then again it is converted back to AC. This process is accomplished by high voltage electronics components, which are arranged in a certain manner. These electronic components are controlled by the microcontroller, which you can refer to as a brain of a generator, for simplicity. The topology of those high voltage electronic components that are used make happen those AC-DC-AC conversion processes are known as converters and inverters; that’s why these generators are called inverter generators.

This conversion of AC power to DC and back again to AC eliminates problems like power spikes, high THD, and high noise, which couldn’t be resolved in those regular generators; In an inverter generator, the engine doesn’t need to run at a constant speed. This is because the engine runs or uses fuel or changes its speed based on the power used from the generator’s terminals. Regardless of the engine’s speed, the inverter generator is capable of producing power with a 60-Hz frequency.

The Working Of An Inverter Generator

This control of output voltage and frequency is performed and monitored by the brain of the generator, and If you haven’t forgotten, it’s a microprocessor. It also gives commands to that high voltage circuitry and changes the speed of the engine accordingly. Again, this is a very complex machine, and It was just a basic understanding to explain how it is advantageous over the regular generator. You will be surprised to know that this same power conversion technology is used in a solar generator for maximum clean power and low noise.

The inverter generators have many benefits over the conventional generators. First, they are fuel-efficient. In the case of conventional generators, it doesn’t matter if you are supplying a tiny night bulb or the whole house; the fuel consumption will be the same. On the other hand, the inverter generators will change their speed and use less fuel according to load demand. That being said, the speed of both the generators will be different; the inverter generators run at a slower speed compared to conventional ones to supply the same load.

How Inverter Generator Differs from The Conventional Generator in Terms of Working

It means the inverter generators offer quieter operation. Besides, they are packed in cases (known as close-frame generators) to reduce the noise even further. Inverter generators use less fuel to supply the same load, which means less fuel consumption and smaller tanks. That’s why they are lightweight and heavily portable. And the main benefit is they produce clean electricity (less than 3% THD), which is not harmful to sensitive electronics like laptops, mobiles, etc.

What is an inverter generator?

The inverter generators have so many advantages over conventional generators, but they aren’t ideal equipment; they have some drawbacks as well. First and foremost, it’s their price point. A decent inverter generator with a few good features is going to cost you more than conventional generators. The high cost means more sophisticated features, and this may increase the complexity for some users. Plus, if it stops working, then a regular generator repairer might not be able to repair it.

How does an inverter generator work?

You will need to take it to an experienced technician. But it is less likely to have a problem with the inverter generators. The inverter generators are less powerful in their output capabilities than those of conventional generators, and it won’t be able to run your larger equipment. Still, if you want more power, then you can connect another inverter generator in parallel, but again you will have to purchase that other generator.

What are The Benefits of Having an Inverter Generator?

Also, the inverter generators are more efficient when used on less load, and if you are looking for a generator to keep running at maximum load, then this may turn out to be a costly deal because the operating cost is more for inverter generators when used at a maximum load.

How to Buy the Best Inverter Generator

The technology has reached far beyond what we can imagine and as a result, there are so many great machines are being developed, which makes life a whole lot easier and the generator is no exception. Generators are around for quite a while now, and they are very useful when the light goes out or when you go camping. In this article, we will explain what the inverter generator is, and how does it work.

What is an Inverter Generator?

Both conventional generator and inverter generator uses fossil fuel to run an internal combustion engine which drives the rotor of the generator. This rotor cuts the electric flux, and voltage is induced through the movement of the conductor. This whole phenomenon is known as electromagnetic induction. The inverter generator is the same as the conventional generator except for some extra circuitry which makes it superior in every aspect.

The conventional generator produces AC power directly but the inverter generator produces AC power, then converts it to DC power, and then again converts it to AC power for clean power and maximum fuel efficiency.

Let’s understand this in detail. As I said earlier, the inverter generator produces the AC power then the rectifier converts it to DC power, and then the inverter circuitry converts it back to AC power. This process has a lot of advantages which are following. First of all, take a look at the below equation. It’s not too hard, just simple math and by understanding this, you will understand all the things.

Here p is the number of poles used in the generator. Poles consist of winding of coils, and they are responsible for producing electricity. All the generators and alternators have two poles. F is the frequency of current and countries like the USA and Canada have 60Hz frequency.

  1. And the frequency of power must be 60Hz otherwise, it will damage your electric appliances.
  2. N is the speed of the rotor. By varying the speed of the rotor you can get the power of different frequencies.
  3. So in order to produce the 60Hz of power supply, the generator speed must always be 3600 RPM (rotation per minute) no matter what.

Now because of the inverting circuitry of the inverter generator, it does not need to run at a constant 3600 RPM to produce 60Hz of supply.
