A genset, short for generator set, is a combination of an engine and an electrical generator used to produce electricity. It is typically powered by diesel, gasoline, or natural gas and is used as a primary or backup power source for various applications, including residential, commercial, and industrial settings.

Gensets are commonly utilized in situations where electricity from the grid is unavailable or unreliable, such as during power outages or in remote locations. They are essential for providing continuous power to critical systems like hospitals, data centers, construction sites, and emergency operations.

Gensets come in various sizes, from small portable units for personal use to large industrial systems capable of powering factories or entire buildings.
