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.
