How to choose a generator for villas and houses

Regardless of how you use your own garden, a minimum degree of comfort is a must in today’s world. And if you can put up with other amenities, the electricity is a fundamental factor with which you can organize all work processes without exception – starting with the banal charging of cell phones and finishing with the connection of power tools and 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 ideal solution to all your problems!

The best manufacturers of generators for country houses – what company to choose

Almost all manufacturers of modern household and industrial equipment have mastered the production of compact generators of electricity. Choosing a model for home use, you should give preference to proven brands, whose products are in everyone’s ears. The following brands can be attributed to such:

1. Bosch
2. Makita
3. Hitachi
4. Hyundai
5. Caterpillar
6. Champion

Examining the range of these brands, you do not necessarily need to choose the industrial, powerful devices. Small, compact generators are enough for countryside use by the eye.

The design and principle of operation of generators of electrical energy

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

1. The stator, which is in a stationary state during the operation of the device. Consists of a steel core and a winding in which the induction current occurs;
2. The rotor is a rotating device that generates an electromagnetic field and, consequently, an induction current;

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

Diesel generators

Proven devices, which are excellent for power supply of your summer cottage on a permanent basis. They are characterized by long autonomous operating time, low maintenance requirements and high environmental friendliness.

Advantages

• Long time (8 to 12 hours) on one filling;
• High fire safety. Diesel fumes are not flammable, which eliminates the possibility of unintentional ignition in abnormal situations;
• Eco-friendliness. Due to the principle of operation, the diesel engine emits much less CO2 compared to the gasoline version;
• Economy. The diesel generator is more economical than its gasoline analogue by 55-60% on average;
• Significant resource and high reliability of the diesel engine;

Disadvantages

• High noise level of the device. The diesel rattle can be heard from afar;
• Regular and very expensive maintenance;
• High price;
• Difficult starting and unstable operation in sub-zero temperatures;

Gasoline generators

Complete contrast to the above devices in general. Gasoline, with all its inherent advantages and disadvantages, is used as a source of electricity.

Advantages

• Easy operation and maintenance;
• Problem-free operation at temperatures of -15 and below;
• Small dimensions and weight;
• Relatively quiet operation;
• Discretion in the kind of gasoline used. Easily “digests” both 95 and even 92 gasoline;

Disadvantages

• Impossibility of protracted work without stopping (4-6 hours on average);
• Due to its construction, it is exposed to moisture and requires protection against it;
• Considerably low service life;
• “Voraciousness”. Such devices consume 55-60% more fuel than their diesel counterparts;

Gas generators

Rather economical devices, which have found widespread use in dacha areas connected to the main gas pipeline. Because of high fire hazard their installation and operation is possible only after agreement with local gas service.

Advantages

• Cheapness of produced electricity due to the low cost of raw materials;
• The possibility of using the device not only as a source of electricity, but also as a source of heating;
• Excellent energy efficiency. Devices of a similar class in 1.Gasoline generators for summer cottages are 5-2 times superior in this parameter to their gasoline and diesel analogues;
• Unpretentiousness to service;
• High reliability and long service life;

Disadvantages

• High fire hazard and the need for responsible approach to the operation and maintenance of such devices;
• High price;
• Expensive repair, requiring high qualification of the master who performs it;

In addition to the above devices, you can find on sale combined type generators that provide the ability to work on two or more fuel sources. Pluses and minuses of these devices depend entirely on what energy sources are allowed to use.

What generator for dacha to choose depending on the type of installed alternator

The suitability of using a particular 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 the uniformity and stability of its operation that determines the quality of the generated electricity, and with it, the life cycle of especially sensitive appliances.

Synchronous generator

The principle of operation of the synchronous generator implies a simultaneous increase in induction and magnetic field and a direct dependence of one on the other. The key element of the construction are miniature graphite brushes – an element made of graphite that is mounted on the stator and is used to transmit electricity. The synchronous generator is an excellent solution for use with equipment that is particularly sensitive to surges – televisions, computers, laptops.

Advantages of

• High quality of the generated electricity, without pronounced peaks and dips;
• High reliability and maintainability;
• Due to the special design can withstand considerable overloads of up to 2-3 times;

Disadvantages

• Necessity of regular maintenance, preventive maintenance and replacement of worn brushes;
• Due to the lack of shielding, such devices create so-called “noise interference” – interference that affects the radio signal;

Asynchronous alternator

As the name suggests this generator has a slightly different operating principle – the induction field increases as the magnetic field increases. In contrast to synchronous generators, these models have a brushless design and are not able to produce high quality electricity. However, it is not required: if during construction work you need a power source for a hammer drill, concrete mixer and other similar devices, the asynchronous alternator is the ideal choice.

Advantages

• Unpretentiousness in operation;
• Low cost;
• The ability to work in short-circuit conditions (important when connecting welding);
• Compact size and weight;
• High degree of protection against dirt and overheating;
• Relatively simple design;

Disadvantages

• Average quality and stability of the generated electricity;
• Weak resistance to peak loads – the connection of powerful equipment is fraught with a drawdown in the work of the device;

What capacity gensets are best for your needs??

One of the key characteristics is the generated power. It represents the total load that can “pull” a particular generator. Depending on it the situation is as follows:

1. If the operation is planned on a country site with a small amount of electrical equipment that does not involve its simultaneous operation, it is enough to have a device that can deliver a power of 2.5-3 kW;
2. If it is necessary to perform construction works and connect a concrete mixer, several rotary hammers or a welding machine, more powerful devices, of the order of 5-10 kW, should be used;
3. If you plan to use a generator as a full-fledged power source, you should look towards diesel generators with a capacity of 5-7.5 kW. The specifics of the diesel device is the ability to work for a long time without interruption, and the power of 7.5 kW is quite enough to ensure stable operation of a large number of equipment simultaneously;
4. In the case when the generator will be used at the same time for power and heating, you should pay attention to models with a capacity of 5-7.5 kW, working on gas or combined devices, one of the power sources of which is gas.

Generator of inverter type

A device that makes sense to use to power particularly sensitive to voltage quality of electrical equipment. Unlike the models described above, in which the voltage is transmitted directly to consumers, the inverter generator has a fundamentally different principle of operation. As the name implies, it converts the generated alternating current into direct current and stabilizes it. Then the current is stored in a special device, either a battery or a supercapacitor, and then converted back to alternating current and in this form served to consumers. At the output we get electrical energy of almost perfect quality;

Advantages

• Maximum quality of electrical power with uniform characteristics, devoid of dips and peaks;
• Small size and weight;
• Quiet, almost noiseless operation;
• The possibility of flexible adjustment for a particular consumer and significant fuel savings as a consequence;

Disadvantages

• High cost;
• In the case of failure of the storage element will require its replacement at an authorized service center – self-repair is not possible;
• Complex design requires regular and qualified maintenance;

How much does a generator for villas cost?

The cost of the generator for country houses – a very multifaceted concept, which can vary significantly depending on the type of a particular device and its technical characteristics:

1. Compact diesel generator with a power output of 2 kW at a time; – Compact diesel generator with a power output of 2 kW at a time; – Compact diesel generator with a power output of 2 kW at a time.5-3 kW capacity in peak mode, costs from 20 to 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;
3. A gasoline generator is the most budget-friendly solution among the presented devices. The cost of a good model from a well-known manufacturer will be from 10 to 45 thousand rubles;
