A diesel generator set, also known as a diesel genset or simply a genset, is a combination of a diesel engine and an electric generator that is used to generate electrical power. The diesel engine drives the generator, which converts mechanical energy into electrical energy.
Diesel generator sets are commonly used as a backup power source for buildings, hospitals, data centers, and other critical facilities that require uninterrupted power in case of a power outage or other emergency. They can also be used as a primary power source in remote areas where there is no access to the power grid or in areas where the power supply is unreliable.
