Although diesel generator sets have lower power, they are widely used in mining, railways, field construction sites, road traffic maintenance, as well as factories, enterprises, hospitals and other departments due to their small size, flexibility, lightness, complete supporting facilities, and ease of operation and maintenance. Diesel generator sets are used in places where there is no connection to the grid, or as emergency power sources in the event of grid failures, as well as for more complex applications such as peak tripping, grid support, and grid output.

Diesel generators have many advantages, such as multiple capacity levels per unit, compact supporting equipment structure, flexible installation location, high thermal efficiency of the generator, low fuel consumption, fast starting, simple maintenance and operation, and low comprehensive cost. Therefore, they are widely used in various fields such as mines, marine ports, outdoor construction sites, municipal machinery, building construction, and aquaculture.
