Rating of the best inverter generators in 2020: review, reviews

Typically, inverter generators are used as back-up power supplies during power outages or power outages. This is an indispensable equipment for the periodic maintenance of country houses; they can be taken to a construction site, on a picnic, on a fishing trip, or on a hike. Among the advantages of inverter power plants are efficiency, low weight and compact dimensions, low noise level during operation, stable functionality. Let's talk about how to choose the right generator, and at the same time take a closer look at the 4 best inverter generators of 2019.

What to look for when buying an inverter generator

An inverter generator is a mini-power plant equipped with a pulse-width modulator that converts current twice: from AC to DC and vice versa. During operation, they are smoothed by capacitive filters and wave oscillations are stabilized. The resulting electricity is of high quality. Let's look at the basic parameters for choosing an inverter generator.

Generator engine type

The engine in the generator can be two-stroke or four-stroke. Push-pull is used in low power devices. It is more economical, simpler to operate, easy to start in the cold. The output voltage floats from 210V to 240V. These generators are not expensive, but they are noisier and less environmentally friendly.

The four-stroke engine is installed on more powerful units with a longer working life. They work quieter, pollute the environment less, but are more difficult to start in cold weather. The output voltage is more even, in contrast to two-stroke engines due to the use of a higher quality homogeneous fuel. Prices for such units are higher.

A generator with a 2-stroke engine is used for trips to nature, for carrying out small-scale work in the absence of a source power supply, for connecting a medium-power tool during repair / construction work, for backup power supply of a small country house. A unit with a 4-stroke engine is suitable for regular use and connecting several devices to it.

Phase

Gasoline generators are single and three phase. To understand what phase is preferable when buying, you should figure out which devices will be connected to the generator. Household appliances are single-phase appliances, so a single-phase generator is preferable for household use.

Three-phase units are welding machines, multi-burner furnaces, pumps. To connect them, you will need a three-phase power plant. But it will be possible to connect household single-phase appliances to it. There is a subtlety with a permissible load on each of the phases, which should not be more than 30%. A converter can be connected to fulfill this requirement.

Power

By power, generators are divided into several groups:

• mobile - 0.35–1.5 kW;
• 2–4 kW - sufficient for power supply of country houses;
• 5-15 kW for cottages;
• more - for intensive use in the field of construction or industry.

To calculate the required power of the generator, you should know at least approximately the number of devices that will be connected to it, their power and the starting current coefficient (in the product passport).

For example, in a house with a power outage, you will have to connect the refrigerator and turn on the light at night. You can also calculate the TV plus. The power of the refrigerator and TV with a pair of 100W lamps will be 0.3 kW × 3.3 (starting current) + 0.08 kW × 1 + 0.2 kW × 1 = 1.27 kW. You need to add a power reserve of 20%. For these purposes, an aggregate with a capacity of 1.5-2kW will be sufficient.

Continuity of work

The duration of continuous operation of the generator depends on many factors, the main of which are the type of engine and the intensity of the load. Low-power mobile inverter power plants operate for up to three hours, which is quite enough in case of a power outage in the country. More powerful units with a 4-stroke engine can work without interruption for up to 10-12 hours.

Cooling

Air cooled units are generally cheaper than water cooled units. However, the continuous operation of an air-cooled generator is not particularly long. This is because the engine heats up faster than the air cools it. However, this is a good cooling option for mobile devices. Water cooled generators can run almost continuously as long as there is fuel. They are more complex, more expensive and require more control.

FAQ

Why are inverter generators better than others?
The inverter motor, which is installed in such generators, has very high performance characteristics. It tolerates peak loads well, works quietly and stably, but most importantly, it produces current with very flat characteristics and constant voltage, which is necessary to supply an accurate equipment.
