Top 7 Diesel Generator Manufacturers in India [2023]

Published on 21st June 2023

An uninterrupted power supply is essential for homes, businesses, and industries.


Also known as a “diesel genset” and “diesel generator set,” a diesel generator (DG) provides backup power to help keep day-to-day operations running smoothly in the event of a power outage or during power fluctuations. 


A diesel generator (DG) uses a combination of an electric generator (also known as a “power generator”) and a diesel engine to generate electricity from diesel fuel.


A diesel generator control panel is the user interface that enables operators to control the generator and review the current status, system diagnostics, and overall functions of the generator.


Furthermore, a silent diesel generator (also known as a “silent diesel genset”) has the same engine as a traditional generator. However, it operates inside a generator enclosure or a sound-proof container, which dampens the sound.
