Low power diesel generators. Low-power diesel generator - your own home power station The smallest gasoline generator

Low power generators in everyday life are sometimes an irreplaceable thing. And the point here is not only that the network voltage is not the most stable electrical unit, but also the need to produce electricity in places where centralized power lines have not yet reached. And then the only solution may be the purchase of equipment such as low-power diesel autonomous generators.

Application area

Often, an independent power source is used to solve such main problems as:

• Organization of backup power supply in parallel with existing centralized power supply lines;
• Installation of autonomous equipment as the only, that is, the main power source.

Sometimes it is necessary to use compact low-power diesel generators to replace non-ideal mains voltage to power particularly sensitive equipment. In this case, we are talking about connecting a single consumer. In a word, the use of such a unit allows you to create more independent external factors(including from unstable centralized power supply) conditions.

Design features and types of devices

The mini diesel generator operates on the basis of energy conversion. The fuel is burned in the engine cylinders, as a result, the expansion energy of the resulting gases turns into mechanical energy.

And the movement of the alternator, which is also the generator in the generator, promotes excitation electromagnetic field, which in turn creates an EMF. The final link of this chain is the formation of an output voltage by the electromotive force, which, after stabilization, is transmitted directly to the consumer.

Watch the video, the scope of use of portable power generators:

A portable low-power diesel generator consists of two main components and a number of systems: an engine, an alternator, a cooling system, a fuel and air supply system for the engine, as well as an automation unit. Depending on the design, the structural elements may be contained in a closed or open housing. But most often, a low-power portable diesel generator is equipped with a rigid frame, to which all elements are directly attached.

Devices are distinguished according to the design differences of the main components, in particular, according to the type of generator:

1. Synchronous;
2. Asynchronous.

Diesel model design

Moreover, the former, due to their increased reliability, gained wider popularity. Additionally, devices are distinguished by the type of current:

• Single-phase;
• Three-phase.

Among low-power equipment there are also three-phase versions, however, a portable single-phase diesel generator is much more common.

It is generally accepted that equipment can be considered low-power with values ​​of this parameter not exceeding 10 kW. To obtain higher quality voltage, which is especially important for sensitive automation of consumer devices, it is recommended to use a diesel inverter generator. The basis of its functioning lies in the ability to transform alternating current to constant and constant to variable.

Criterias of choice

Low-power devices are usually used in domestic settings. It is often accepted as a fact that the assumption that a small power value determines a low level of device performance, but in the case of diesel generators this assumption is not true, since devices of this type have a fairly long engine life. To choose a successful model, you need to decide on a number of parameters:

• Type of current of the device. Most often, low-power equipment is found in a single-phase version, but there are also autonomous three-phase diesel generators of low power. Moreover, this type is more productive.
• Load capacity or power. The range of values ​​for this parameter is from 1 to 10 kW. If you need to choose a more powerful device, then you should not look for such a model in the category of low-power equipment. The permissible load is determined by adding up the powers of all consumers that are planned to be connected to the generator.
• Fuel consumption of a diesel autonomous generator. This parameter directly depends on the volume of the fuel tank and the performance level of the device. Before deciding on a model, you should plan how long the device will be used without shutdowns.
• Starter type. In versions up to 10 kW, there is a separate manual pull or electric starter, as well as a combined version, when the generator can be set in motion in two ways.
• Dimensions and weight are important parameters if the user plans to move the device. For example, the smallest standalone Honda diesel generator weighs only 13 kg.

Review of models and manufacturers

Model AD6-T400

Among domestic equipment, you can choose the right model, since the range of low-power equipment is quite wide. One of the fully functional devices is a Russian-made diesel backup generator AD6-T400.

Its power is 6 kW, the type of current is three-phase, and accordingly the output voltage is 380 V. The device is equipped with an electric starter and a volumetric tank of 18 liters. The cooling system is air.

Such characteristics are quite enough to organize an autonomous power supply in a country house or in a house. The average cost of this model is 140,000 rubles.

Vepr ADP 2.2

The production of low-power diesel generators in Russia is quite widespread. Another option among the rich assortment is Vepr ADP 2.2-230 VYa-B. Its average cost is 100,000 rubles.

Moreover, the design is almost half the weight of the previous model. Characteristics include low power - 2 kW, manual starter, fuel tank volume - 12.5 liters, as well as single-phase current.

Among the foreign brands, the Kipor diesel backup generator is popular, in particular, the KDE12EA model worth 190,000 rubles. This is high-performance equipment, designed for a power of 9.5 kW.

The cooling system in it is liquid, there is a fairly spacious fuel tank - 23 liters, thanks to which the device will function without shutdowns for quite a long time. As you can see, Russian-made diesel generators do not lag behind imported devices. Both are presented in various designs and are designed for different categories buyers.

Before installing the generator, you need to make sure that the surface where it will be located is sufficiently flat. If the device body is open, it is important to protect the main components of the mechanism from moisture and large debris getting into the system. Outside the premises, such equipment must be operated in a protective casing.

It is advisable to organize a supply of cool and purified air to the engine. The removal of exhaust gases outside the premises is a mandatory part of the installation process of such equipment.

Watch a video about the KDE12EA model:

Thus, if you take into account all the main parameters when choosing a generator, you can get a device that is sufficiently productive to supply power to a consumer with certain characteristics. This is one component of successful operation of the device.

Sometimes it happens that without your own small power plant it's impossible to get by. Especially in everyday life. And this applies not only to cases where there is no centralized power supply system. The network may be unstable or even shut down periodically. The problem is solved by purchasing an ASU - autonomous generator set.

The main parameter by which we evaluate this or that product is the ratio of price and quality. If we talk about generators, this is also safety.

The modern ASU market satisfies any request. Today you can easily buy both a cheap and an expensive model from a well-known manufacturer. However, most optimal household option is a low-power diesel unit.

How is a low-power diesel generator better than its gasoline counterpart?

The first question that arises in the reader’s mind is: why not a gasoline generator? After all, it is cheaper. It's simple. Gasoline installations are only relevant for short periods of time. Due to their technical characteristics they are not capable of becoming full-fledged alternative source of electricity. A diesel generator, on the other hand, can operate uninterruptedly for a long time. Moreover, the fuel and maintenance costs of diesel units are an order of magnitude lower than those of gasoline units.

Diesel generators, in addition efficiency, are highly reliable and fire safety. Unlike gasoline units, diesel engines can be equipped with additional fuel tanks, placed in a room made of materials that support combustion, and even used in areas with insufficient ventilation.

Low power diesel generators are distinguished by their portability. They are easy to install in a special container for transportation. It will be needed if there is no separate room for the installation.

Low power diesel generators as a backup power source

Low-power diesel generators are ideally suited as backup source of electricity. This category includes installations with productivity up to 12 kW with a frequency of 1500-3000 rpm. If you plan to operate the generator for approximately 400-500 hours per year, then a high-speed diesel engine (3000 rpm) is suitable. For more intensive use, experts recommend a low-speed installation (1500 rpm). Such generators, with the same output power, are more expensive, but have an increased service life and a reduced noise level.

An important factor is cooling method diesel generator. A low-power air-cooled generator would be optimal as a backup energy source. True, it is quite noisy. Selecting installation with liquid cooled(water or antifreeze) is ideal for constant work with high power consumption. Its disadvantage is a higher price and lower fuel economy.

Low-power diesel generators Yammar and Lombardini

To date the best manufacturer low-power diesel ASU (air-cooled) is a Japanese company Yanmar. For example, the Yanmar ADP 2.2-230 VYa-B diesel generator is unique in its kind and can become an indispensable assistant for those who need a compact and reliable source of electricity. The installation combines all the advantages of professional diesel power plants: long service life and high efficiency.

Yanmar diesel generators are among the leading ones on the world market diesel engines in terms of reliability and performance. In combination with a synchronous brushless self-regulating diesel generator SINCRO, the electric unit allows you to continuously provide electricity to the consumer with one refueling for 12-15 hours. At the same time, the installation maintains excellent performance power quality. The presence of 12 V DC output terminals on the generator makes it possible to recharge the battery.

Among the low-power AGUs, interesting models are based on an unpretentious diesel generator. Lombardini. High power at low specific consumption fuel, air cooling, operation in a wide temperature range (-35 °C...+45 °C).

Other companies that produce the highest quality diesel generators include: Acme, Hatz, Iveco, Honda, Yamaha, Kubota, Robin. Domestic units are produced in Chelyabinsk, Vyatka, Rybinsk, Yaroslavl, Tula, and Vladimir.

Low power amateur diesel generators

Amateur low-power generators differ from professional ones in a number of ways. Household diesel engines are often made with side valves, while professional ones are made with overhead valves. Change of oil the latter require at least every 100 hours of operation. For household ones, you can work longer on one oil. The cylinder walls of amateur models are usually made of aluminum, while those of professional models are made of cast iron.

Certainly, important parameter- price. Diesel generators, the prices of which are below average, can hardly boast professional class. The cost of a good low-power diesel ASU should be at least 140 thousand rubles. By the way, diesel units are divided into synchronous and asynchronous. Synchronous ones provide the generated voltage in the network with the slightest fluctuations, within 5%. It is safe to connect sensitive equipment, such as a computer, to a network powered by a synchronous generator. True, such models are naturally more expensive.

The portable generators presented in the store's website catalog operate using air-cooled engine technology. The advantages of such devices are:

• compactness;
• mobility;
• ease of maintenance.

Kinds

Diesel portable generators. They are the most economical option and can operate smoothly for quite a long time. However, air cooling of the engine does not allow such devices to be used as the main sources of energy supply even for not very powerful consumers. But as backup power plants, they are often used and demonstrate exceptional efficiency when operating in emergency mode, as well as a more affordable operating cost due to lower consumption and low fuel prices.

Gasoline generators. Such installations ensure the operation of such consumers as: local lighting, electronics, communications, heating elements, tools, household electrical appliances, chargers etc. It is worth buying a portable generator that runs on gasoline if you have a limited budget, availability high requirements to the noise level, as well as the convenience and speed of starting when low temperatures(a low-power diesel engine is usually more difficult to start compared to a gasoline station). Our company’s assortment also includes specialized equipment - unified complexes that include a gasoline power unit and welding machine. Possessing versatility and adaptability to welding work, such options are very popular among consumers, although their cost is higher than that of conventional stations without welding stations.

All generators can be divided into two groups – light and heavy. Heavy generators are used in industry and construction. Modern stores have a wide range of portable gas generators. Such devices do not require special storage space. They are easy to transport, and the generator power is quite enough for domestic needs.

Advantages of light generators.

The main factor influencing the weight of the generator is the engine. A four-stroke engine is more metal-intensive, therefore it is approximately twice as heavy as a two-stroke engine.

Another factor is the power of the gas generator. As the power of the unit increases, the power of the engine that drives the entire system increases. As a result, the weight of the structure also increases.

A low-power unit will be much lighter. Gasoline generator, active power which does not exceed 1 kW, will weigh up to 20 kg. The weight of a unit with a power of 2 kW and above starts from 50 kg.

Mobility is the main advantage of light gas generators. Given their size, they are reliable and economical. Thanks to its low noise level, the unit can be installed in a country house, in an apartment, or taken on a long journey.

The lightest gasoline generators

We will spend more detailed review some models of small portable gas generators.

Svarog YK950I-M3.

The smallest gasoline generator, the weight of which does not exceed 12 kg. The kilowatt power is enough to power a light bulb, TV or even a small refrigerator. The portable generator is very light and compact; you can take it with you on hikes or leave it at the dacha as an emergency power source.

Herz IG-1000.

A portable single-phase gas generator designed for six hours of battery life. Weight – 13 kg. The power is less than the previous model - 720W. It will not be possible to power the refrigerator, but it is enough for a light bulb or low-power tool.

Patriot Garen&Power SRGE950.

Low-power generator for primary needs. Active operating power – 650W. The weight of the device is 17 kg. The unit lasts for four hours of continuous use. Limited characteristics are compensated by a low price - about 4,000 rubles.

Champion IGG1000.

One-kilowatt gas generator equipped with a soundproof casing. Thanks to built-in overload protection, such a mobile power generator is best option for everyday needs. The power of the unit is sufficient for the needs of the average consumer.

The lightest gasoline generator is an eight-kilogram inverter station with a very original design in the form of a ball.

All other things being equal, the weight of an inverter electric generator is about a third less than that of a conventional analogue. The disadvantages of such devices include high cost and optimal performance at very light loads. The advantages include reduced fuel consumption, environmental friendliness, and mobility.

An inverter gas generator is an ideal choice if you plan to charge a phone or tablet, connect a TV, electric stove or computer.

Connecting a hammer drill or grinder can cause damage.

Only the necessary devices need to be connected to light generators. If the refrigerator is not needed, there is no point in powering it. In addition, at the moment of startup it will need several times more energy than during normal operation, which can negatively affect the generator.

For hiking trips and other trips, a mobile generator with a power of 0.7-0.8 kW is suitable. The unit will fit in the trunk of any car.

Thanks to a special noise-insulating casing, the noise level is quite low. The power of such a gasoline electric generator is enough to charge mobile device, connections lighting fixture or tape recorder.
