What is the difference between an inverter generator and a conventional generator?

 Today, I would like to introduce the difference between "inverter generator" and "generator in general". The power waveform has a lot to do with this difference.

There is a waveform in electricity. This is also affected by fluctuations in frequency, voltage, etc.

Generators that can provide high-quality electrical power with a power waveform close to the sine wave are called "inverter generators".

A sine wave is a waveform represented by a sine curve. In other words, it is a smooth waveform and there is no distortion in the curve.

The electrical waveform from the power company supplied to ordinary households is a sine waveform.

This inverter generator is suitable for use with electrical equipment with built-in computers such as general personal computers and rechargeable power tools.

However, there are exceptions, so you should check with the manufacturer of the product you want to use before using.

On the other hand, a communal generator is usually located next to a festival pavilion.

Because there is no inverter, the waveform distortion during power generation will be large.

Is it a bit easier to understand if you look at the picture above? The waveform produced by the inverter generator on the right is a nice sine waveform.

Since it is a generator then of course some waveform distortion will occur, but if it is an inverter equipped generator the distortion rate is low,

There is no problem in using electrical equipment.

On the other hand, the waveform produced by the common generator on the left side is highly aliased and distorted.

If you use this generator to power electrical devices with built-in microcomputer such as personal computers, rechargeable power tools and air conditioners,

Never use it as it will damage the electrical appliances you already use!

So if a generator is generally completely useless compared to an inverter generator, that is not the case.

There are also advantages.

It is "hard to break" and "cheap".

Compared with inverter generators, the structure is simple, so there is less damage that requires high repair costs.

In addition, the sales quantity will be much cheaper.

In my experience, when it comes to power generation, a typical generator is “over 12 years of good performance”.

The inverter generator gives the impression that "the inverter controller of the generator usually fails in about 6-7 years."

Of course, depending on the model, frequency of use, and electrical equipment used, there will be differences, so it cannot be said to be unconditional.

In addition, generators generally operate without problems even with slight overcurrents,

In an inverter generator, the use of electrical equipment in an overcurrent state will lead to failure of the inverter controller, etc.

It is a slightly more delicate structure than an ordinary generator.
