What is a Genset?

what is a genset

So you’ve been reading up on generators lately. Maybe trying to find one for your home or business. And you keep coming across this word: genset. What is a genset? What do people mean when they say genset? The word “genset” is short for generator set, and the word is often used interchangeably with just generator. Today, we’ll define genset more precisely, how it works, and the benefits.

What is a Genset?

First, like mentioned above, a genset is short for generator set. Specifically, it consists of a motor and alternator set in a base frame. Although, other parts include:

  • Batteries
  • Fuel tank
  • Control panel
  • Automatic transfer switch
  • And more…

Therefore, using the term “genset” is really a way of emphasizing or expressing the individual parts as a whole. Furthermore, you can see how the terms “generator” and “genset” find interchangeable use.

How It Works

Second, how does a genset work? Here’s a brief synopsis.

  • Initially, the engine converts chemical energy (fuel) into mechanical energy.
  • Then, that mechanical energy spins the alternator rotor to create electrical energy.
  • Next, spinning the alternator rotor through a magnetic field between the rotor and alternator’s stator creates a voltage on the alternator stator (electromagnetic induction).
  • Last, when the voltage on the stator connects to a load, electrical current flows, and the generator produces power.

So, this all describes how generators power data centers, hospitals, construction sites, office buildings, and even homes. Hopefully this clarifies what is a genset.


Third, the benefits of a genset should be fairly self-explanatory. In fact, there’s probably not too many places you go or experiences you have where generators are not involved! From your workplace to your smartphone to your favorite places to eat. In the modern world, all of these things and places require gensets to function. In addition, without generators, none of them would be possible!

However, not all gensets are created equal. Poorly-made and maintained ones can come with heavy financial and environmental costs. Yet, if you use a quality, well-maintained unit, you can expect the following benefits.

  • Reliability
  • Fuel efficiency
  • Scalable design
  • Robust construction
  • Automatic or manual paralleling
  • Automatic loading control
  • Local or remote operation
  • Low emissions
