Gasoline generators are used during construction until electricity is supplied; and even after it has appeared, they will not be superfluous on the farm - especially if power outages occur quite often. How to choose a gasoline generator and which 12 generators of this type are worthy of the title of the best in 2019, read below.

What characteristics to look for when buying a gasoline generator?
Before buying a generator, you should decide on the desired parameters. They depend on several conditions:
- whether the gasoline generator will be used as a primary or backup source of energy;
- where it is supposed to be installed - indoors or outdoors;
- whether you need to move it often;
- whether it is necessary for it to be able to start in automatic mode.
Based on this, it will be possible to determine the main characteristics that a gasoline generator should have.
Types
There are three main types: synchronous, asynchronous and inverter generators. The first two can be considered together. Synchronous ones are also called brushless, and asynchronous ones are brushless. The latter are generally used quite rarely, they are simpler in structure, but the current they provide is of low quality, which makes the scope of their application rather narrow. At home, it is more advisable to use synchronous generators.
However, inverter generators provide an even more stable current than synchronous ones, therefore they are usually used to power expensive high-tech devices. However, they are also more expensive. Both synchronous and inverter gas generators are used as home gas generators.
engine's type
Two-stroke and four-stroke are used. The former are cheaper and simpler, and therefore weigh less and more compact. At the same time, two-stroke engines are characterized by increased fuel consumption, loudness, exhaust toxicity and rapid wear. Therefore, their use is a priority only if the generator acts as an additional power source, and it is desirable to be able to place it in a separate room.
If it is used as the main one, that is, it works much more, it is preferable to use a four-stroke engine. It is equipped with its own lubrication and gas distribution system, as a result of which it is easier and cheaper to maintain, it produces much less noise and harmful emissions, and it will work longer.
Phase
Single-phase generators can only supply power to appliances that require 220 V. Three-phase are designed for both 220 V and 380 V. Accordingly, if all the appliances in the house are single-phase (most often this is the case), then the generator should be bought the same. And only if there are three-phase devices, it will be necessary to acquire an appropriate generator.
Power
By this parameter, devices are distinguished:
- Low power - up to 5 kW. This is almost always enough for giving. As a rule, they have modest dimensions, so you can even go on various trips with them.
- Medium - up to 10 kW. Often a low-power generator is not enough for construction work, as well as for cottages. They are larger than the previous type and are often equipped with wheels for transportation.
- High power - over 10 kW. They are rarely required, for especially large houses or construction projects.
To determine which generator group you need from, you should calculate the total power of all devices that will work from it. If the generator is of a synchronous type. You need to add another 20% to the result, if it belongs to inductive, then it will need a lot of power when starting, so the result needs to be multiplied by 2.5 times.
Continuity of work
The generator will be able to maintain the operation of the instruments until the fuel runs out, and then it will have to be interrupted to refuel it. Accordingly, the time for which there is enough stock is called the time of continuous operation. It depends on the ratio of fuel consumption per unit of time and the volume of the tank. Low power generators are often equipped with small ones that allow them to work for 2-3 hours, large ones - for 20 liters, which is enough for 10 hours. But if necessary, you can also find a small generator with a large tank that can work without interruption for a long time.
Cooling
It happens air and water. The second is more expensive and larger, but also more efficient. For devices of low and medium power, most often the first is sufficient.

8. Kolner KGEG 5500EM
In most cases, overly powerful generators are not needed, and 5 kW is sufficient. Kolner offers just such a device: the company tried to make it so that it could work continuously as long as possible. Thanks to a rather economical engine with a tank volume of 25 liters, it can not stop for 13 hours, so that most of even long power outages will pass without any inconvenience. It has quite large dimensions and weighs 70 kg, the device costs 35,000.

9. DDE GG3300Zi
If 5 kW is not required, do not overpay for too powerful generators. You can take this model, designed for 3.2 kW of active power (but the real one is lower than declared by the manufacturer) and costs 23,000 rubles. It also weighs less - 35 kg, which allows you to move the device alone without any problems. But the lower power did not affect the noise level - it is 91 dB, which is quite a lot. The engine is equipped with a relatively small fuel tank, only 9 liters, as a result of which the continuous operation time of this generator is average - 7 hours. For most situations, this is sufficient.

10. Carver PPG-3600A
The generator is even less powerful: it is designed to power devices that consume up to 2.5 kW in total. The volume of the tank is larger here - 15 liters, which allows the four-stroke engine to work on one refueling for up to 12 hours. But it also weighs, despite not less power, more than the previous one - 40 kg. But it makes much less noise - 67 dB, which is already quite acceptable. And its main advantage is its low cost, it can be purchased for only 11,500 rubles. Of course, the capacity will not be enough for many things, but it will be quite enough for basic needs.

11. Eurolux G1200A (8500r)
If a generator of only 1 kW is enough, you should pay attention to this one. Weighing only 28 kg, it is able to provide energy to devices for 10 hours: a very good option for both going out into nature, and for installation in the country, if you need to ensure the functioning of just a few devices. It consumes little fuel - only 600 ml per hour, produces little noise during operation - 65 dB, and produces almost no emissions. Provides a stable voltage, and at the same time is inexpensive - 8,500 rubles. Of the shortcomings, it is worth noting that the tap on the gas tank often leaks.

12. ELITECH BES 950 R (650 W) (6 000 R)
If efficiency and a long resource from the generator are not needed, you can get by with a two-stroke engine. Usually the generators equipped with it cost less, like this one - you can get it for 6,000. But it does not impress with its parameters either: the power is only 650 W, so many devices cannot be supplied with energy from it. The volume of the tank is 4 liters, which is enough for 8 hours. The generator is very compact and easy to carry, weighs 21 kg, has little noise (56 dB). All this makes it a good choice for trips, but it is not suitable as a stationary one.

FAQ
Why does the generator stall after turning on the load?
The most common cause is overload. It is worth trying to turn off some of the devices and start it again. If there is clearly no overload, the reasons may vary. First of all, check the oil level in the engine, then change the dirty filters, check the spark plug, the fuel system.
The generator is outputting a low voltage - what could be the problem?
Check the voltage at the output terminals from the terminal box to the outlet. Most likely, the wires have oxidized or burnt somewhere - this is often seen immediately. Even if not, the multimeter will determine where the voltage loss is occurring. If no problems were found with the power circuits, the voltage generator regulator should be checked, and then the windings for an interturn short circuit.
