How to choose the right diesel generator set?

In order to choose the right diesel generator set, you must first understand the total power required by the equipment to which the diesel generator is to be connected and the type of power supply. At the same time, it is also necessary to determine whether a mobile trailer diesel generator or a fixed-mount diesel generator set is required according to the specific situation. Finally, it is also necessary to determine whether a voltage regulation system is required, which generally smoothes the output voltage to avoid damage to some delicate electronic equipment that will be connected to the diesel generator set.

First, determine how much power your diesel generator set needs?

To determine how much power the required diesel generator set needs, you need to know not only the total power of the equipment that will be running at the same time, but also the peak power consumption, especially at startup. For example, an electric motor may consume up to three times its rated power at startup. Therefore, the diesel generator set must be able to provide the peak power consumed by all the equipment that needs to be started at the same time. For some resistive equipment such as lighting, televisions, small appliances, etc., a 30% safety factor must be added when determining the power of the diesel generator set. For inductive equipment, their power must be multiplied by 3 to take into account the peak consumption.

Second, determine what type of engine to choose for the generator set you are going to buy?

The generator set is equipped with an internal combustion engine. Depending on your needs and the type of fuel available, you can choose between gasoline, diesel or gas engines:

Gazette generator sets are usually compact, quiet and versatile. Typically, these generator sets have lower power, up to 6kW, and provide single-phase current.

Diesel generator sets are more suitable for commercial, industrial, construction and other scenarios that require high power and long or even continuous use. For example, in places such as construction sites and manufacturing plants, using diesel generator sets is more economical and reliable than gasoline or gas generator sets of the same power.How do diesel generator sets start?

Smaller generator sets, up to 3kW, can be equipped with a manual starting system. We do not recommend this type of system if you have to use the generator set frequently.

Most more powerful generator sets are equipped with an electric starter connected to the battery.

Determine whether you need a single-phase or three-phase generator set?

For general home use or small shop use, a single-phase generator set can meet the needs, but for professional use, such as construction sites, manufacturing plants, power stations, building complexes, industrial parks, large shopping malls, hospitals, schools and other scenes, a three-phase generator set may be required to power machines that require more power.

What other important features should be considered when choosing a diesel generator set?

Voltage regulation: The cheapest generator sets are not equipped with an output voltage regulation system. Without this regulation system, the equipment connected to the generator set may be damaged, especially if its electronic components are sensitive to overvoltage. Therefore, we recommend that you check whether your generator set is equipped with an automatic voltage regulator (AVR) to avoid damage to your equipment.

Cooling system: Small power generator sets are air-cooled and do not run all the time. The manufacturer may indicate full autonomy when the tank is full, or continuous autonomy time and the rest time required for cooling between two uses. For diesel generator sets for industrial or commercial use, they should be equipped with a liquid cooling system.

The noise level of the generator set may be a determining factor in the comfort of the user or the surrounding people. The noise generated by high-power generator sets can easily rise to 100 decibels (dBA). If the noise level is an important factor for you, you may want to consider a silent box-type diesel generator set. Silent box-type diesel generator sets can effectively reduce the noise generated by the operation of the generator and meet the use of some scenarios with strict requirements on noise.

In general, when choosing a diesel generator set, you should make the most correct choice based on your actual situation. Whether you want to choose a high-power diesel generator set or a small or medium-sized generator set, or need a silent diesel generator or a mobile trailer diesel generator set, we can provide you with the high-quality diesel generator set that suits you best.
