TOP 5 diesel generators with a power of 5 – 7 kW

Until relatively recently, there was no power equipment in the range of the Ukrainian brand Ergo. But full-scale Russian aggression changed everything. The company began to order generators from proven, trustworthy Turkish and Chinese manufacturers and supply them to the Ukrainian market. Thus, in 2023, the Ergo EDW6000E diesel generator appeared in online stores, which has an affordable price (by the standards of diesel power plants of this power class), decent quality and good technical characteristics. It has a rated power of 5.5 kW - quite enough to provide a small private house with the amount of electricity necessary for lighting, operation of several computers, a refrigerator and a water pump in the absence of mains voltage. Since the device is equipped with an automatic regulator (AVR), which maintains a stable voltage at 230 V (with slight deviations), connected household appliances will be protected from voltage surges and sags (but particularly sensitive devices may need a stabilizer). On the front panel of the generator there are several connectors for connecting different types of consumers. A 32 A socket is designed to power powerful equipment or connect to the home electrical network. The 16 A socket can accommodate plugs from extension cords, power tools or household appliances. And the 12 V terminals are intended for recharging batteries or powering devices operating on direct current.

By inserting the key into the ignition switch on the front panel, you can use an electric starter to start the “heart” of the generator - a diesel engine with a working volume of 455 cm³ and a power of 11 hp. Operating at full power, it consumes a little more than 2 liters of diesel fuel per hour of operation (in this mode, a fully filled tank with a volume of 12.5 liters lasts for 6 hours). The device is equipped with a multi-function display that can display the frequency and voltage of the output current or the hour meter readings necessary for the user to promptly change the oil, clean the filter and perform other engine maintenance operations. Wheels and handles attached to the frame allow the user to roll the generator from place to place without strain - very convenient if the equipment is stored in a garage or shed and is pulled out only in the event of a power outage.

The Gucbir GJD7000H diesel generator belongs to those units that are quite capable of maintaining the almost normal functioning of a private home during a lack of electricity. Having a rated power of 6 kW, it can provide power not only to lighting fixtures and computer equipment, but also to more “gluttonous” consumers, including refrigerators and freezers, pumping stations for autonomous water supply or circulation pumps that pump coolant through the heating system. And when working on a construction site, a generator can serve as a power source for power tools and a variety of equipment, such as concrete mixers, welding machines or heat guns. To perform all of the above functions, you can use two sockets that are located on the panel of the device. One of them is a regular one ( 16 A), for a standard plug. The second is power ( 32 A), for connecting to an electrical panel or supplying power to powerful consumers. The current to each of them is supplied through an automatic regulator (AVR), which maintains a stable 230 V (with slight fluctuations that do not affect the operation of the equipment). Next to the outlets there are also terminals that supply 12 V DC. These can be used to recharge car batteries.

The key component of the device, which makes the Gucbir GJD7000H so attractive for those who want to buy a good generator, is the 418 cc diesel engine. It has a power of 12 hp. and is equipped with an electric starter, which allows you to start the engine not manually, but by simply turning the key in the ignition. When operating at full power, the engine consumes about 280 grams of diesel fuel for every kilowatt-hour of electricity produced. The fuel tank has a volume of 15 liters. In order to timely perform engine maintenance work (that is, change the engine oil in the engine crankcase and clean the filter elements), the user is given the opportunity to control the operating hours using a multifunction display (in addition to the hour meter readings, it can also display the current voltage or frequency of the output current). All components and assemblies of the generator are mounted on a powerful steel frame. A handle and four large wheels are attached to it, allowing you to easily move the equipment over uneven ground on a construction site or effortlessly roll it out to your garden plot in the event of a power outage.

The line of generators of different types and power classes, which are produced under the Hyundai brand, has a good reputation due to the fact that they are all equipped with high-quality branded engines. For the Hyundai DHY6500L electric generator, for example, the functions of the power plant are performed by a 474 cc 4-stroke diesel engine Hyundai D480 with a power of 10 hp. It has a reliable and time-tested design, which ensures the “survivability” of the motor and its long service life. The manufacturer claims that the service life of this engine (that is, the operating time before major repairs) exceeds 3,500 operating hours - a very respectable figure by the standards of small generators. When servicing a load equal to 50% of the rated power, this diesel engine consumes 1.29 liters of fuel per hour of operation (thus, the fuel reserve in a 12.5-liter fuel tank is enough for almost 10 hours). Although the generator does not have an electric starter, manual starting of the engine does not require much effort from the user due to the fact that the engine is equipped with an Easy Start system - a decompression valve that makes it easy to crank the crankshaft using a pull-out cable.

Electricity is generated by a synchronous alternator with a copper winding, high-quality “armor” of wires and protection against overloads and short circuits. The parameters of the output current are controlled by the AVR module - an automatic regulator with high-capacity capacitors and an intelligent control system that maintains the output voltage at a level as close as possible to 230 V. This generator is designed to serve a load with a total power of up to 5 kW. That is, it can be used to power equipment with power tools at a construction site, and to ensure the life of a small private house during power outages. To provide power to users, the device is equipped with two sockets(both designed for standard plugs) and a 12 V DC output in the form of terminals to which you can “attach” wires for charging car batteries (cables with “crocodile clips” are included). Although the Hyundai DHY6500L generator is designed for stationary operation, transport kits (wheels and handles) are sold separately for it, allowing you to move the 95-kg unit with minimal effort.

Designed to serve loads up to 6kW, the ITC Power DG7800SE diesel generator has enough power to power lights and computers, essential appliances (such as the refrigerator and freezer) and pumps that draw and pump water from wells. coolant through pipes and batteries. It is equipped with an electric starter to start the engine and has a connector for connecting an ATS unit. Thanks to the presence of this connector, power equipment can be connected to the house in such a way that the generator automatically turns on if the electricity disappears and turns off when it appears (to install such a system, you must additionally buy an automation unit).

The installation has a completely closed housing, which serves as a soundproof casing and provides partial protection from precipitation (however, it is not recommended to keep the equipment outdoors all the time). Underneath it are hidden all the components and assemblies that provide the ability to generate electricity: a 498 cc diesel engine with a power of 12 hp, a synchronous alternator with an automatic voltage regulator (AVR) and a 13-liter tank for storing diesel fuel. The engine has good (by the standards of an internal combustion engine of this volume) fuel efficiency - 1.3 l/h (at a load of 50% of the rated power). It is equipped with a pre-heater, which guarantees easy, quick and reliable starting of the diesel engine in cold weather. The set of outputs for connecting electricity consumers is represented by two sockets. One has a standard shape (like ordinary household sockets) and can pass current up to 16 A. The second socket is a power socket (32 A). Through it you should connect the generator to the distribution panel of the house or supply power to equipment with high energy consumption. In addition to the connectors, there is a multifunctional display on the front panel that can show the current values of output voltage, current and load, as well as hour meter readings (users need them for timely maintenance of the device). Wheels are attached to the frame, thanks to which the generator can be easily moved on flat surfaces, such as concrete areas or paths lined with paving stones.

The Matari MDA8000SE-ATS diesel generator (like other models of power equipment from the same MDA series, which includes equipment of different power classes) is designed to work as a backup source of power supply for small objects: private houses, shops, offices, workshops, etc. “Heart” The installation is a diesel engine with a power of 10 hp. with a working volume of 455 cm³. Operating at half its power (this mode is the most typical for a backup generator), the engine consumes about 1.4 liters of fuel per hour - the supply of diesel fuel in a fully filled 16-liter tank is enough for almost 11 hours of autonomous power supply. To save users from having to start the diesel engine manually, the manufacturer equipped the generator with an electric starter powered by a battery.

This generator can serve a load with a total power of up to 5.5 kW. Thanks to the presence of an automatic voltage regulator (AVR), it holds 230 V well, allowing only minor (not affecting the operation of the connected equipment) deviations when the load changes. Regular electrical consumers (power tools or household appliances) can be plugged into the 16 A socket on the front panel of the device. The second outlet is a power outlet (32 A), it is used to supply power to a household electrical network or to powerful consumers (such as construction equipment or machine tools). Near the outlets are 12V output terminals. These can be used to charge car batteries or power some DC appliances. The device comes with an ATS unit - a “box” with automation that continuously monitors the presence of voltage in the network and turns the generator on and off when needed. To ensure automatic start-up of the equipment, you just need to integrate the ATS unit into the power supply network between the meter and the distribution board.

Thanks to the presence of an autostart system, the Matari MDA8000SE-ATS generator can become a real “lifesaver” for a private home or small store during periods when frequent power outages occur. Among its advantages, it is also necessary to mention very quiet operation (due to the presence of sound insulation), good protection from weather factors (the metal case completely covers all components and assemblies from moisture and dust) and ease of movement (the device has wheels for transportation).
