Types of Mini Diesel Generators
Mini diesel generators are available in various types which are suitable for operation in different conditions, efficiency levels, output capacity, and mobile characteristics. The following are the main types of mini-diesel generators based mainly on their construction, design, and functionality.
Portable Mini Diesel Generators
The small, portable-sized diesel generators are, to be more specific, inherently portable. They are compact in size, light in weight, and very easy to carry, with almost all portable equipment. These generators are used for construction, camping, and remote work where it is in power requirement as needed. Despite being small in size, portable mini generators can produce a considerable amount of electrical power, though auxillary it is not as high as stationary ones.
Inverter Diesel Generators
Inverter mini diesel generators utilize a process known as the phase sequence reversal process, whereby the generated currents are changed from direct currents to alternating currents. These generators provide a stabilized output of power, which can be variable, but only within very narrow limits. Therefore, in this case, the generators are appropriate for using equipment that requires relatively stable power supply, such as computers and medical equipment. The advantage of the inverter diesel generators is the compact size and fuel economy and the reduction of output waveform, which may affect the equipment.
Stationary Mini Diesel Generators
Stationary generators are normally fixed in one place, but they can also be mini diesel generators. They come in larger sizes compared to portable models, but in provision of power, they are less powerful than bulk generators. Such generators are applied in areas where power supply is required constantly but cannot provide grid power, such as remote work stations or rural houses. They are also designed for continuous use, so they can offer reliability and efficiency, more than just intermittent use machines.
Brushless Mini Diesel Generators
Brushless mini diesel generators do not have brushes in their power generation system. This construction facilitates a longer life span, more reduced maintenance compared to brush-type generators. Brushless generators also provide a constant power supply. It is applicable in cases where the generators have to be running for long hours, such as at a construction site or providing back-up power in an emergency situation.
Industrial Applications of the Mini Diesel Generator
Small diesel generators are applied in industry as such because they are reliable and efficient in generating power, especially in remote areas where there are no main power sources. The following are some typical industrial applications of mini-diesel generators.
Construction Sites
Mini diesel generators are very common on the construction site because the construction sites are often located in remote areas that do not have any electricity from the mains. The generators provide power to operate tools, lighting, and equipment and make working at construction sites possible even without connection to the electric power grid.
Oil and Gas Industry
Mini diesel generators are used extensively in the oil and gas industry to power extraction and processing equipment in remote areas where other types of power may not be available. For example, they may power pumps, compressors, and other machinery used for drilling and extraction.
Agricultural Operations
Mini diesel generators are used in agriculture to power equipment such as irrigation systems, pumps, and other machinery used in farming. They are particularly useful for farming operations located in rural areas without access to electricity from the mains.
Telecommunications
Mini diesel generators are used by telecommunications companies to power cell towers and other equipment in remote areas where there is no electricity from the mains. They ensure that communication services are not interrupted, even in areas that are not connected to electricity from the mains.
Mining
In the mining industry, mini diesel generators power equipment and machinery used in mining operations. They are particularly useful for mining operations located in remote areas without access to electricity from the mains. For example, they may power drills, trucks, and processing equipment used to extract and process minerals.
Emergency Backup Power
Diesel generators mini can be used to provide an emergency backup power supply in industrial situations where electricity from the mains is crucial for running processes and equipment. They are particularly useful in situations where power outages can cause serious damage or losses, such as critical manufacturing processes or operating life-support medical equipment.

How to Install
- The installation of a diesel generator set is the same process as the steps one has to follow when installing a stand-by power systems.
- The first thing one needs to do is put the generator within a reasonable distance from the mains supply conductors and the nearest electrical switchboard.
- Then, the generator needs to be connected to a changeover switch with the switched consumed circuits.
- Next, the changeover switch is connected to the generator and mains supply through the open terminals.
- After that, the diesel generator should be connected to the electrical switchboard with the main power input.
- Finally, the changeover switch should be installed at the switchboard to ensure the mains supply and generator are prevented from concurrent connecting.
How to Use
- Check the oil level: Before using the generator, one should check the oil level to ensure the generator is well lubricated so that it does not damage the engine for lack of oil.
- Fill the fuel tank: After checking the oil level, fill the fuel tank with diesel fuel. Ensure to use the right type of fuel for the generator because the generators are meant to use either high or low cetane number diesel.
- Connect the battery: If the generator has an electric start, one should connect the battery to ensure the generator will start. If it is a pull start or manual start, there is no need to connect the battery.
- Set theCircuit Breakers: Before starting, turn off all the circuit breakers on the generator and the equipment that is to be powered by it.
- Prime the pump: Some generators require the fuel pump to be primed to remove any air from the fuel lines. Refer to the manual to see if this step is necessary for the generator.
- Start the generator: For electric start generators, turn the key or press the start button to start the generator. For pull start generators, follow the instructions for starting the generator.
- Let it warm up: After starting the generator, let it run for a few minutes at no load to warm up the engine. This will help increase the generator's lifespan.
