What are diesel generators up to 10 kW and what are their advantages

Interruptions in electricity can cause significant losses on construction sites, in industrial buildings. Its absence will make it impossible to perform standard processes. To solve the problems of primary and backup energy supply, you can use special equipment - diesel generator stations at 10 kW. In this article we will briefly describe how they are arranged and what are.

Varieties of diesel generators

Diesel generators rated at 10 kW are small in size. They are conditionally classified into two types according to the format of execution: frame and bonnet. The first have an open design. They are used indoors or outdoors in fine weather.

Frame diesel generator

The second is protected by a metal box. It resembles a cabinet with hinged doors providing easy access for station maintenance. The presence of special insulation in the structure helps to reduce noise. This design is relevant in places where significant noise load is not allowed, there is a risk of dust, moisture, etc. entering the unit. The stations differ in the rated current strength and in the number of phases. There are single-phase and three-phase modifications. The choice depends on the type of connected consumers.

Bonnet version

In addition, diesel generators can differ in power, cooling method (air, radiator (air-water) and dual-circuit (another name water-water), as well as mobility (stationary or mobile).

The benefits of diesel generators

Among summer residents, owners of country houses, construction crews, owners of small production facilities, 10 kW diesel power plants are in great demand. Their important advantages:

  • the possibility of use as a backup and permanent source;
  • high reliability, resistance to external interference;
  • relatively low cost of maintenance and refueling;
  • operational launch;
  • high level of efficiency;
  • operational safety.

All modifications of diesel generators have a similar structure. Their design includes an alternator, a diesel engine, a tank for filling with fuel, controls, a frame or a “cabinet”. Single-phase models provide one or two 220 V sockets. Three-phase stations are equipped with 220 V and 380 V outputs. They can have 12 V DC terminals. They can be recommended for connecting welding equipment and other powerful equipment.


One of the main components of 10 kW diesel generators is an electric starter. Thanks to it, it is possible to automatically or remotely start. The unit consumes significantly less fuel compared to gasoline counterparts.

Principle of operation

Well, briefly consider how a diesel generator works.The ignition of compressed diesel fuel produces the so-called gas expansion energy. With its help, as well as due to the crank mechanism, the crankshaft comes into action. It begins to rotate, creating mechanical energy and thereby rotate the rotor of the diesel generator. Excitation of the electromagnetic field occurs and, as a result, an emf arises.

The occurrence of an electromotive force, in turn, creates an output voltage that is necessary for the end user.

So we examined what diesel generators are, what is their operating principle and variety. Most often, this embodiment is used in country houses for backup power supply, as well as on farms, on construction sites, in service stations and production workshops.
