How to choose a generator for giving and home

Regardless of the purpose for which you use your own summer cottage, at least the minimum degree of comfort is a mandatory requirement in the modern world. And if you can put up with other conveniences, then electricity is a fundamental factor by which you can organize all without exception work processes - starting with the banal charging of a mobile phone and ending with connecting the power tool and the electric heating of the room. However, not every site has a constant source of alternating current. In such a situation, an electric generator is the perfect solution to all your problems!

The best manufacturers of generators to give - which company to choose

Practically all manufacturers of modern domestic and industrial equipment have mastered the production of compact electric power generators. When choosing a model for domestic use, preference should be given to proven brands whose products are widely known. These include the following brands:

1. Bosch

2. Makita

3. Hitachi

4. Hyundai

5. Caterpillar

6. Champion

Studying the range of these brands, it is not necessary to choose industrial, powerful devices. Small, compact generators for dacha operation is enough for the eyes.

The design and principle of operation of electric power generators

The principle of operation of all devices of this class, without exception, is the possibility of obtaining electrical energy from any other kind of it. For this purpose, a generator is used (or, as it is otherwise called, an alternator) - a device that converts mechanical energy into electricity. This device includes two main nodes:

1. The stator is stationary during operation of the device. Consists of a steel core and a winding in which induction current occurs;

2. The rotor is a rotating device that generates an electromagnetic field and, as a result, induction current;

The electrical energy generated by the generator is a consequence of the transformation of mechanical energy. It is produced by rotation of the motor shaft - another key element of devices of this class. Depending on what source of fuel is used, all generators are divided into several general groups.

Diesel generators

The devices checked by time which perfectly will be suitable for power supply of your seasonal dacha on constant conditions. They have a long battery life, unpretentious maintenance and high environmental friendliness.

Gasoline generators

The complete opposite of the above devices in general. As a source of electricity is used gasoline with all its intrinsic pluses and minuses.

Virtues

• Ease of operation and maintenance;

• Trouble-free operation at a temperature of -15 and below;

• Small dimensions and weight;

• Relatively quiet operation;

• Unpretentiousness in a grade of used gasoline. Easily "digests" and 95, and even 92 gasoline;

disadvantages

• The impossibility of long-term work without stopping (on average 4-6 hours);

• Due to the peculiarities of the construction, it is afraid of moisture and demanding protection from it;

• Significantly lower lifespan;

• "Voracity". These devices consume 55-60% more fuel than their diesel counterparts;

Gas generators

Quite economical devices that are widely used in suburban areas connected to the main gas pipeline. Due to the high fire risk, their installation and operation is possible only after coordination with local gas services.

Virtues

• Low cost of electricity generated due to the low cost of raw materials;

• The possibility of using the device not only as a source of electricity, but also a source of heating;

• Excellent energy efficiency. Devices of this class are 1.5-2 times higher in this parameter than their petrol and diesel counterparts;

• Unpretentious service;

• High reliability and increased resource;

disadvantages

• High fire risk and the need for a responsible approach to the operation and maintenance of such devices;

• High price;

• Expensive repairs, requiring high qualifications of the master who carries it out;

In addition to the above devices, commercially available generators of the combined type, providing the possibility of working on two or more sources of fuel. The pros and cons of these devices entirely depend on what sources of energy are allowed to use.

Which generator to choose depending on the type of alterator installed

The suitability of using one or another generator depends not only on the type of fuel used, but also on the principle of operation of the device that generates electrical energy - the alterator. It is on the uniformity and stability of its work that the quality of the electricity produced depends, and with it the life cycle of particularly sensitive electrical appliances.

Synchronous generator

The principle of operation of a synchronous generator involves the simultaneous increase in the magnitude of induction and the magnetic field and the direct dependence of one parameter on another. A key element of the design are miniature graphite brushes - an element made of graphite, mounted on the stator and used to transmit electricity. A synchronous generator is the perfect solution for use with equipment that is particularly sensitive to voltage surges — TVs, computers, laptops.

Virtues

• High quality of electricity produced, without pronounced peaks and dips;

• High reliability and maintainability;

• Due to the design features it is able to withstand significant overloads, reaching 2-3 times;

disadvantages

• The need for regular maintenance, maintenance and replacement of worn brushes;

• Due to the lack of shielding, such devices create so-called "pickups" - interference that affects the radio signal;

Asynchronous generator

As the name implies, this generator implies a slightly different principle of operation - the growth of the induction field follows the increasing value of the magnetic field. Unlike synchronous generators, these models have a brushless design and are not capable of producing high quality electric power. However, it is not required: if during the construction process you need a source of electrical energy for a perforator, a concrete mixer and other similar devices, an asynchronous generator is an ideal choice.

Virtues

• Unpretentious operation;

• Low cost;

• Ability to work in conditions of short circuit (important when connecting welding);

• Compact dimensions and weight;

• High degree of protection against dirt and overheating;

• Relatively simple design;

disadvantages

• Mediocre quality and stability of the generated electricity;

• Weak resistance to peak loads - connecting powerful equipment is fraught with a drawdown in the operation of the device;

What device power choose?

One of the key characteristics is generated power. It reflects the total load that a generator is able to “pull”. Depending on it, the situation is as follows:

1. If the operation is planned on a summer cottage with a small amount of electrical equipment that does not imply its simultaneous operation, a device capable of delivering 2.5-3 kW of power is sufficient;

2. If it is necessary to perform construction work and connect a concrete mixer, several perforators or a welding machine, the use of more powerful devices, of the order of 5–10 kW, will be required;

3. If you plan to use the generator as a full-fledged source of electricity, you should look in the direction of diesel generators with a capacity of 5-7.5 kW. The specificity of the operation of the diesel device lies in the possibility of long-term operation without interruption, and the power of 7.5 kW is enough to ensure the stable operation of a large amount of equipment at the same time;

4. In the case when the generator will be simultaneously used both for power supply and for heating, one should pay attention to models with a power of 5-7.5 kW, working on gas or combined devices, one of the power sources of which is gas.

Inverter type generator

A device that makes sense to use to power especially sensitive to the quality of the voltage electrical equipment. Unlike the above models, in which the voltage is transmitted directly to consumers, the inverter generator has a radically different principle of operation. As the name implies, it converts the generated alternating current into direct current and stabilizes it. Then the current is accumulated in a special device - either a battery or a supercapacitor, after which it is again converted to an alternating one and in this form is fed to consumers. The output is electrical energy of near-perfect quality;

Virtues

• Maximum quality electricity with uniform characteristics, devoid of dips and peaks;

• Small dimensions and weight;

• Quiet, virtually silent operation;

• The possibility of flexible settings for a specific consumer and significant fuel savings as a result;

disadvantages

• High price;

• In the event of failure of the cumulative element, it will be necessary to replace it at an authorized service center - independent repair is not possible;

• Complex construction requires regular and qualified service;

How much does a generator cost to give?

The cost of a generator for a dacha is a very multifaceted concept that can vary significantly depending on the type of specific device and its technical characteristics:

1. A compact diesel generator capable of delivering 2.5-3 kW of power in peak mode costs between 20 and 80 thousand rubles;

2. A device with similar parameters, working on gas, is somewhat cheaper: depending on the manufacturer, the buyer will have to "lay out" from 15 to 40 thousand rubles;

4. The petrol generator is the most affordable solution among the devices presented. The cost of a good model from a famous manufacturer will be from 10 to 45 thousand rubles;
