What To Know Before Purchasing A Diesel Generator Set?

July 06, 2022

What does a diesel generator set or simply diesel generator mean? The combination of a diesel engine and an electric generator constitutes a diesel generator, which is used to create electrical power. If there is a disruption in the regular supply of electricity or locations that do not have a link to the power grid, an emergency power source such as a diesel generator set might be used.

Accordingly, here we are going to shed some light on different aspects of diesel generators, including various types of diesel generators, specifications to focus on when purchasing a diesel generator set, and a bit of friendly advice in the end. So, let's get started without any delay.

Types of a Diesel Generator Set

Numerous companies manufacture diesel generators in various sizes, configurations, and models, which may be purchased from many different suppliers around the globe. Therefore, before you go out and get a diesel generator, you should familiarize yourself with the following several types:

Industrial or Residential Diesel Generators

Industrial diesel generator sets are often massively sized and can provide significant amounts of electricity over extended periods. As their name indicates, they are often deployed in settings with substantial electrical power demand. On the other hand, residential generators are usually compactly sized and have power outputs that are limited to a particular range. As far as their applications are concerned, they are well suited for usage in workplaces, small stores, and homes.

Classification Based On Power Output

The range of power output that diesel generators may achieve is quite broad and can be categorized appropriately. For instance, a diesel generator with a capacity of 3kVA may be used to power electrical equipment and appliances, such as air conditioners, computers, numerous ceiling fans, and so on. They are suited for usage in residential settings, retail stores, and even small workplaces. On the other hand, a diesel generator set with a capacity of 2000kVA would be appropriate for use in large enterprises or other locations with significant electricity demand.

Air-Cooled or Water-Cooled Diesel Generators

Generators that are cooled by air are dependent on air to provide the cooling function necessary for the generator. There is just one component that is used, and that is an air intake system. In contrast, water-cooled diesel generator sets have a different system responsible for the cooling function since they depend on water as their primary cooling medium. Generators that are cooled by water need more maintenance than generators that are cooled by air.

Factors to Consider While Purchasing a Diesel Generator Set

So, here we discuss several factors to keep in mind when purchasing a diesel generator:

When buying a diesel generator set, there is a choice between single-phase and three-phase connectors. Determine if the electrical connection to your house or business is single-phase or three-phase. Then, choose an appropriate generator based on that information.


Before purchasing a diesel generator, it is essential to have a solid understanding of the needs of the house or business. It is possible to employ generators ranging from 2.5 kVA to even more than 2000 kVA at a location, depending on what is required there.

Fuel Consumption

When buying a diesel generator set, one of the most vital considerations that one should give attention to is fuel consumption. Please find out the generator's fuel consumption per hour and per kVA (or kW) and the fuel efficiency it provides concerning the load.

Control and Power Management Systems

Generators, which can automatically transfer electricity from the grid to the generator throughout a power loss and vice versa, display warnings (low fuel and different performance concerns) and offer a comprehensive range of analytical data. Eventually, it assists in boosting the efficiency of the diesel generator set. The power management system contributes to optimizing the generator's performance concerning the load demand to achieve the best possible fuel efficiency.


If the generator is maintained nearby, there may be an issue with the amount of noise it emits. Some diesel generator sets are equipped with noise absorption technology, which drastically reduces the amount of noise produced by the generator.

Mobility and a Manageable Size

The amount of effort involved in transporting a diesel generator set may be minimized by purchasing one equipped with wheels or slots that facilitate lifting. Additionally, bear in mind the dimensions of the generator with the storage area that is accessible for it.

Find an Experienced and Competent Supplier

The moment has finally come to investigate the advice that we made at the beginning of this piece of writing. Along these lines, finding a seasoned and dependable provider of diesel generators, together with their engines and components, is the single most crucial step in the process of buying a diesel generator set. Suppose you have already exerted much effort but have come up empty-handed in your search for a reliable provider. Then, please allow us to assist you in this matter.
