Which generator is best to choose for a private house, villa and building?

As the statistics show, the sales of generators in Ukraine are constantly increasing. The media claim that this is caused by permanent interruptions with electricity, because water is used for heating water, and for heating - electric heaters. Today, we need a larger supply of electricity while coal reserves are running low. The most practical and economical way out is to buy a generator.

Buying a generator as an emergency power source is a reasonable solution, because turning off the light forces us to postpone the necessary business, creates a lot of inconvenience. And what to say about the enterprises, where the shutdown of electricity stops all production.

To choose the most suitable generator, you need to consider some of the nuances, which we will tell you about.

Calculate the total power of electrical appliances

Let's forget for a while about brand awareness and additional functions. So, we get that the cost of the generator directly depends on its power. However, you need to be careful and do not take the price as the main criterion. It is better to look at the power and to determine for yourself the desired indicator for yourself.

If you save and do not waste time on miscalculation, then the capabilities of the chosen model may not be enough for your premises. But too powerful a device you need little than it is useful: fuel will be wasted.

Therefore, to begin with, we write out all electrical appliances and, on the contrary, write power. This indicator is looked at in the instructions, technical data sheet, and tag. Now we divide all the units into very important ones and those without which we can safely do without. For example, in the first category gets a refrigerator, heater, and the second - a vacuum cleaner or iron.

As a result, we can allocate all the equipment that will work continuously. We consider the total power and obtain the necessary index. Here, consider interchangeable devices, for example, you can abandon the TV in favor of the computer.

Remember the power reserve, because for the normal operation of the generator, you need even a small margin. To the amount received, we recommend adding 20%. So, you prevent possible breakdowns and can in case of emergency even connect additional equipment that is not taken into account.

Generator power rating

If you make calculations very difficult for you or if you doubt the results, you can make a choice based on the power class:

• — Up to 3 kW - suitable for lighting dacha or connecting household appliances. For example, you can simultaneously use a refrigerator and a compact water pump.
• — Up to 5 kW - you can additionally connect a TV, computer. Such indicators are enough to cook dinner on the electrolyte.
• — Up to 7 kW - suitable for large houses, where there is electric heating, boiler, air conditioning. Such models can also be used for commercial enterprises.
• — From 10 kW - professional units, designed for large enterprises, production workshops.

220, 380 or 220/380 W - what to choose?

Single-phase devices are ideal for home use, because three-phase devices are very rare in everyday life. Three-phase structures are equipped with two sockets: 220 V and 380 V. Thus, they are suitable for providing electricity to any equipment.

Universal stations belong to the class of professional. Combine everything you need to work on one and the three phases. It is not recommended to take a three-phase model for home use, because it involves a lot of difficulties.

Fuel: gasoline, diesel or gas

Gasoline generators are suitable for domestic use, backup power. Such models differ in compactness, low noise and affordable for most at a price. For the home choose devices with a power of 3-5 kW, and for professional operation - from 7 kW.

Diesel generators are effective for increased loads. Equipped with a reliable engine with a resource that exceeds by several times the index of gasoline designs. Calculated for regular and long-term use. Suitable for operation in environments where there is no electricity. Continuous operation time is 10 hours.

Two-fuel generators can function both on gas and on gasoline. Such models are more versatile, safe to operate. Are capable to work till 20 o'clock without refueling. Often, gas is used as the main source of fuel, and gasoline - as a constant.

Inverter generators are devices developed using modern technologies. Their advantage lies in the issuance of "pure" voltage without changes and jumps. It features compact dimensions, economical fuel consumption, low noise operation, environmental friendliness. Manufacturers provide for such devices protection from dust and moisture. The structures are operated in offices, farms, medical institutions.

Generator start: manual, electric, remote, automatic

A manual starter is a standard option, which is suitable only for household appliances. To work with more powerful generators, you will have to make great efforts, especially since at low temperatures the situation is aggravated even more.

Electrostarter is an easier way, it works on the built-in battery. The main advantage in the ability to work even in frost.

Remote launch is a very comfortable solution. You can turn on the generator at an acceptable distance, without leaving home.

The automation is suitable for commercial premises. Such models are connected to the network, the electronic unit in case of its disconnection delivers the corresponding signal, and the system starts independently. The most economical are the models with automatic triggering on the switching on and off of the fixed network. These devices are able to save fuel and your time.

An open frame or noise-proof casing - what to choose?

An open frame involves placing the engine inside a solid frame. The latter protects the structure from mechanical damage, ensures convenient transportation of the unit, dampens vibrations. The advantage of such models is rapid cooling, better cope with heavy loads.

The noise-proof casing also protects internal mechanisms from damage, dust and moisture. Equipped with a strengthened cooling system, which is especially important for cases where the generator runs from 10 hours.

Which alternator to choose

Asynchronous - a simple option without winding on the rotor and carbon brushes. Has a light weight, affordable price, but it can not guarantee a stable voltage. We recommend to abandon it if you use sensitive technology. However, it is ideal for welding, because it is resistant to short circuits.

Synchronous - more complex construction, equipped with copper winding and carbon brushes. The cost of such models is higher and the weight is greater, but it ensures the supply of stable voltage and high-quality current.

Additional functions

The AVR function is responsible for the voltage stability. It is irreplaceable for modern technology, because for it the voltage surges can be disastrous.

Power socket with a current of 32A is designed to remove all power from one outlet. This is very important if you need to connect a very powerful unit.

Display. Choose a model in which all the necessary indicators are displayed. For example, due to the availability of an hour meter, you can timely conduct those. maintenance of the device.

Generator buy can be on 130.com.ua with delivery to Kharkov, Odessa, Kiev and Ukraine.

Heating the engine provides a stable temperature for the idle motor. So, any problems with the launch are excluded. Often found in diesel models, because they are badly turned into frost.
