What Is a Power Inverter Generator

Before defining what a power inverter generator is, you should be aware of the inverter and its function.

There are basically two types of current – alternating and direct. The Alternating current (AC) is in the form of sine waves and operates at a frequency, whereas direct current (DC) is represented by a straight line. When we have to switch from DC current to AC, an inverter is used.

This concept has also been used in the constructions of power generators, and the result is a form of generator which has higher efficiency than the normal one, which converts mechanical energy into AC. There are many advantages that a power inverter generator has over a traditional generator.

    Lightweight and compact

    The greater efficiency means that a compromise can be struck on the weight of the generator. This adds to the portability and compactness of the generator, making it more user friendly. The weight reduction can be as much as 1/3rd of the total weight.

    High quality electrical output

    The quality of the electrical output can be significantly enhanced in the inverter power generator by using a Pulse Width Modulator. This modulator removes the distortion from the electrical output by smoothening out the sine wave. The resultant increase in efficiency can be up to 2.5 to 5 percent.

    High fuel efficiency

    The power inverter generators have the ability to adjust the engine rpm’s (rotation per minute) according to the load requirement. This is done in such a way that the engine frequency and power are not altered. Thus there are no load variations, reducing vibrations and this increasing the life of the engine blades and assembly.

    Low noise output

    As the power inverter generators are not running at maximum load all the time, they don’t produce maximum operational noise. The noise can further be dampened by the use of sound mufflers. Different companies use different versions of this equipment.

    Function in parallel

    These inverters can also be used in parallel, provided the specifications of two or more than two generators are the same. This procedure is done when smaller generators are used to achieve higher net power, which in other case could have been produced by a generator of higher rating.
