What Are The Components Of A Genset?

A genset, also known as a generator set, is a portable power supply source that consists of an engine and a generator. Gensets offer a convenient and efficient means of providing electricity without requiring access to the power grid, and you can choose to use a diesel generator or gas generator.

Gensets also serve as backup power sources anywhere from worksites to homes to businesses and schools, generating electricity to provide power to run equipment such as household appliances and construction equipment or to keep critical systems in operation in case of power outages.

A genset differs from a generator, although the terms generator, genset, and electric generator are often used interchangeably. A generator is actually a component of a genset—more specifically, a generator is the mechanism that converts energy into electrical power, while a genset is the engine that drives the generator to power the equipment.


To operate correctly, a genset has a set of components, each with a crucial function. Here’s a breakdown of the essential components of a genset, and what role they play in delivering electrical power to your site:

Frame: The frame—or base frame—supports the generator and holds the components together.

Fuel system: The fuel system consists of fuel tanks and hoses that send fuel to the engine. You can use diesel fuel or gas depending on whether you’re using a diesel genset or one that runs on gas.

Engine/motor: Running on fuel, the combustion engine or motor is the primary component of a genset.

Exhaust system: The exhaust system collects gases from engine cylinders and releases them as quickly and silently as possible.

Voltage regulator: A voltage regulator is used to ensure a generator’s voltage levels remain constant, rather than fluctuate.

Alternator: Another key component—without it, you have no power generation—the alternator converts mechanical energy into electricity.

Battery charger: Perhaps self-explanatory, the battery charger “trickle charges” your generator’s battery to ensure it is always full.

Control panel: Consider the control panel the brains of the operation because it controls and regulates all the other components.
