Autonomous power supply: 5 gas generators with synchronous alternator

The motto of the Ukrainian brand Intertool is “A tool for every home!”. And she relentlessly follows him, offering functionally "charged" products at a tasty price. As an example, let's "break the bones" of the DT-1155 gas generator from the category of "five kilowatts".

The model is assembled on a high-strength metal frame with overall dimensions of 617x485x458 mm. The weight of the unit in running order came close to one centner (96 kg, to be exact). Wheels come to the rescue in transporting the device. The four-stroke generator motor is started manually or with an electric starter by turning the key in the ignition. At the peak, the power of the device reaches 5.5 kW, in the nominal mode it produces “honest” 5 kW.

At full load, Intertool DT-1155 works without a break for more than 11 hours in a row - that's how much fuel is enough in the 25-liter tank of the model. The fuel for the generator will be unleaded gasoline with an octane rating of at least 86. Also, the manufacturer has equipped its brainchild with an automatic voltage regulator (AVR), which maintains stable parameters of the generated electricity, thereby preventing voltage and current surges.

The gas generator provides the user with three 230 V AC outlets and a 12 V DC output at once (most often used for charging car batteries). The model withstands many hours of electrical energy generation cycles without the risk of serious breakdowns. In the event of a manufacturing defect, the manufacturer provides a one-year warranty on the product.

The history of the Swedish company Husqvarna goes back three centuries ago. The manufacturer entered the equipment market with a pronounced household orientation in 1959. This is what made the brand famous worldwide. One of the products in this category is the G5500P synchronous alternator gas generator.

The model is intended for "registration" in the territory of private households or small construction sites. The rated power of the station is 5 kW, at the peak of its capabilities, it produces 5.5 kW of power with short-term current surges several times higher than the nominal level for reactive loads. The generator is able to easily generate energy to power power tools, welding machines and other equipment with high starting currents.

"Make friends" with the unit will not be a problem even for those users who are dealing with generators for the first time. The main thing is to pour lubricants into the oil filler neck with a volume of 1.1 liters and do not forget to fill the tank of the device with gasoline. The model is started with a key or manually. In order to take advantage of electric start, you will need to buy a battery separately, since it is often not included in the standard package of the Husqvarna G5500P.

On the device control panel there are two 230 V sockets, one of which is power (32 A), as well as a 12 V DC output. hours worked. Not in the best way, the situation with the model is only with the level of noise - despite the damper supports, the generator makes a very noticeable noise (97 dB), which is explained by the open design of the "body".

The once powerful Hyundai conglomerate was fragmented at the turn of the second and third millennia into many independent divisions. One of them focused on the production of tools and related equipment, in particular, generators for deploying backup power systems.

The HHY7020FGE model is notable for its omnivorous nature of the type of fuel used: the unit “eats” A-92 gasoline, as well as bottled and natural gas. Gasoline consumption per hour of continuous operation of the device is about 1.5 l / h (at a load of 50%), bottled gas for the same period of time the generator "eats" from 1.7 liters. Switching between fuel types is carried out by shifting a special damper with the generator engine turned off.

The heart of the device is the Hyundai IC390 four-stroke engine with top valve seating. Such a design has a beneficial effect on ensuring complete combustion of the fuel mixture in the working chamber. The generator motor is able to boast of an increased motor resource (with timely maintenance), along with it, “under the hood” of the model, you can see a synchronous alternator with a copper winding. The device can easily cope with both active and reactive loads, which provides for the possibility of working with power toolshaving high starting currents.

The power plant controls are concentrated on the front console. There are an ignition switch, two 230 V sockets (one standard for 16 A and one power for 32 A), power connectors for low-voltage devices (12 V), an emergency switch and a mini-display for displaying the generated voltage along with the "mileage" of the motor. The generator lacks only transport wheels. If it were not for their absence, it would be absolutely useless to present Hyundai HHY7020FGE claims.

When it comes to high-end cleaning technology, products under the Karcher brand name immediately come to mind. At the same time, the assembly of related equipment has been set up at the manufacturer's facilities. For example, recently the company's portfolio has been replenished with gasoline generators.

The middle model in the newly minted range of mobile power plants generates electricity at a rated power level of 5 kW. This will be quite enough to organize backup power for lighting fixtures, household appliances and power tools. Also, the unit will serve as an autonomous source of energy for high-pressure washers Karcher.

According to the "passport", the model consumes 2.08 liters of fuel per hour. However, in fact, this indicator can “float” within wide limits - the “voracity” of the unit directly depends on the level of power consumption of the connected consumers. At maximum engine speed, the gasoline reserves in the 25-liter tank of the device are enough for a 6.5-hour duration of electricity generation. In half power mode - for 10-12 hours in a row.

In terms of electrical outlets , the model is equipped with three 230 V sockets and 12 V DC outlets. A stable voltage level is maintained by the AVR auto-regulator, and the built-in voltmeter helps to monitor the current voltage value. The voltage value is displayed on the information mini-display. It also shows the "mileage" of the motor, i.e. number of hours worked. Convenience when transporting the unit is added by tubeless wheels in combination with a folding push handle. The work of the German Karcher engineers is difficult to overestimate - the brand's gas generators turned out to be strong on all fronts and have practically no drawbacks. With a stretch, only increased noise during operation (95 dB) can be classified as such.

A couple of months after the celebration of the centenary since its founding, the Japanese company Makita “rolled out” the EG6050A gas generator into the arena of power equipment. It happened in 2015 and after several years after the announcement, the model has not lost its relevance.

At the heart of the mobile power plant is a four-stroke Loncin 190F engine with a volume of 420 cm³. The engine is started by the forces of both electric and manual starters. The design of the unit provides 2 outputs for 230 V and connectors for connecting 12 V DC consumers. The AVR system on board the device prevents surges by automatically adjusting the output voltage.

The gas generator weighs almost 100 kg. And this is “dry”, i.e. without oil and fuel. To avoid premature wear of key components, the manufacturer equipped the device with an oil level sensor, and you can visually assess the amount of fuel in the gas tank through the viewing window. Despite its solid weight, Makita EG6050A is easy to transport. Fortunately , for ease of transportation, the unit was armed with inflatable wheels and folding handles.

In the reviews of the model, in separate lines, the high quality of the assembly of the gas generator and its long service life are noted. True, you will have to pay a considerable amount for the model. In the segment of "five-thousanders", the device occupies the top lines of the podium, perfectly fitting into suburban households or small construction sites as a backup or temporary source of power supply.
