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

If you are looking for relatively inexpensive equipment for autonomous power supply during periods of lack of electricity, then EnerSol EPG-5500S is one of the good options. The rated power of this generator is 5 kW (short-term operation with a load of up to 5.5 kW is allowed). This power is quite enough to ensure the life of a private home, small store or office (of course, if you do not turn on all the available household appliances at the same time). The device is equipped with a synchronous alternator with an automatic voltage regulation (AVR) unit - devices connected to the generator will receive an almost stable 230 V (with slight fluctuations within the permissible limits, but without significant “jumps” and “sags”). To connect the load, the generator has three sockets : two regular (for a standard plug, limited to 16 A) and one power (32 A). It is also possible to power devices operating on direct current or recharge car batteries - for these purposes there are 12 V output terminals on the panel.

A 390 cc engine with a power of 13 hp is used as the power plant that powers the generator. with manual start. Fuel is stored in a 26-liter gas tank (when operating at full power, the gasoline supply lasts approximately 13 hours). To make the massive 72-kg unit easy to move from place to place, the manufacturer has equipped it with a set of wheels and handles (they are in the box as a set of parts for self-assembly).

If manual starting is a “problem” for you (after all, pulling the cable can be a little tiring), then you can pay attention to other options for the same generator: EnerSol EPG-5500SE(with electric starter) or EnerSol EPG-5500SEA(with electric starter and a connector for connecting to the ATS unit, which ensures automatic start-up of the equipment in the event of a power outage). But, naturally, due to the presence of additional components and assemblies, these models cost more than the generator in question.

If long power outages are expected, or you have to work on a construction site that is not connected to the power grid, then it is reasonable and profitable to buy a generator that can operate for a long time without stopping or refueling breaks. Such devices include the ITC Power GG7000FE gasoline mini-power station. Thanks to the spacious gas tank (volume 25 l) and moderate fuel consumption (1.3 l/h at half load), this generator can operate autonomously for up to 20 hours in a row. By half load here we mean servicing electricity consumers, the total power of which is 50% of the rated power of the generator, equal to 5 kW.

The unit is equipped with a 4-stroke gasoline engine with a power of 13 hp. with a working volume of 389 cm³. Thanks to the presence of an electric starter and a rechargeable battery, the user is spared the need to pull the “shrink” to start the engine (however, a cable is present just in case). There is an ignition switch on the dashboard, so starting the generator by unauthorized persons without a key is completely impossible. There, on the front panel, there are two sockets for connecting household appliances, power tools or other consumers, as well as 12 V output terminals for recharging batteries or powering devices operating on DC. Since the device is equipped with an automatic voltage regulator (AVR), it produces a stable 230 V (with minor fluctuations when the load changes, which do not exceed the permissible limits). To visually monitor the output voltage, the generator is equipped with a voltmeter. Since the device is not at all light (72 kg without taking into account the weight of the fuel in the tank and engine oil in the crankcase), wheels and handles are attached to the frame, allowing the unit to be moved by one person.

The Konner&Sohnen KS 7000 gas generator is well suited to serve as a backup source of electricity for a private home, retail outlet or other small facility that requires electricity for operation or normal functioning. The device is capable of “pulling” a load of up to 5 kW (in short-term mode - up to 5.5 kW, but this should not be abused). Thus, it can easily ensure the operation of lighting fixtures, computer equipment, a fan heater, a refrigerator and a pump that pumps water from a well - everything that is required to wait out a temporary lack of electricity. And when working on a construction site, he is quite capable of servicing several units of power tools or a small welding machine.

Electricity is generated through the joint operation of a gasoline engine (working volume 389 cm³, power 13 hp) and a synchronous alternator. An automatic voltage regulator (AVR) is responsible for a stable 230 V (with a deviation of no more than ±5%). Current frequency, output voltage and motor operating hours can be monitored using the multi-function digital display. The device is equipped with a standard set of protective systems: a fuse that trips in case of overload, and an oil sensor that turns off the engine if the crankcase is “dry”. The set of outputs intended for connecting electricity consumers is represented by one 16 A socket for a standard plug, one 32 A power socket and terminals that supply direct current with a voltage of 12 V.

If you are embarrassed by the need to manually start power equipment every time the power goes out, you may want to consider slightly more expensive versions of the same generator. For example, the Konner&Sohnen KS 7000E version is equipped with an electric starter, and the Konner&Sohnen KS 7000E ATS has an automatic system that detects the presence or absence of voltage in the network and completely independently, without any human intervention, turns the gas generator on and off when necessary.

The Matari MX10000E generating set is designed to serve electricity consumers with a total power of up to 7 kW. It is equipped with a 4-stroke gasoline engine with a power of 16 hp. with a working volume of 439 cm³. The engine starts “from the key” thanks to the presence of an electric starter and a battery (but there is also the possibility of manual starting in case of a deep discharge or absence of a battery). To store a supply of gasoline, the device is equipped with a 25-liter capacity. Working with a load of 60% of the rated power, the generator consumes about 2 liters of gasoline per hour (that is, a fully filled tank is enough for 12.5 hours of uninterrupted power supply in this mode). Since the unit is quite massive (weight 85.4 kg excluding fuel and engine oil), it is immediately equipped with wheels and handles that allow the generator to be moved with relatively little effort.

Electricity is generated by a synchronous alternator with an all-copper winding. The automatic voltage regulator (AVR) is responsible for the quality of the current, which maintains the output voltage at 230 V (with a small error that does not affect the quality of operation of most electricity consumers and the safety of connected devices, except for particularly “sensitive ones”). To connect the load, the Matari MX10000E generator has one 32 A power socket (designed to supply power to the home electrical network or serve powerful consumers, such as a welding machine or other construction equipment) and one regular 16 A socket (to power household appliances or power tools with standard plugs ). The front panel also contains 12V DC output terminals (most commonly used for charging car batteries) and a digital display that can show voltmeter or hour meter readings.

If we take into account the power, moderate “appetite” for fuel and good quality, then the Matari MX10000E is quite suitable as a generator for the construction or maintenance of a private home in the absence of electricity. Note that the Matari MX10000E-ATS is also available for sale - a version with automatic start, which differs from the model under consideration only in that it has built-in automation to start the generator in the absence of mains voltage.

One of the key advantages of Hyundai generators is the fact that they are equipped with high-quality engines. The five-kilowatt Hyundai HHY7050FE ATS is no exception. This gas generator is equipped with a proprietary Hyundai IC420 engine with a displacement of 420 cm³ and a power of 15 hp. It starts confidently, operates stably in different modes (the manufacturer guarantees normal operation of the internal combustion engine at temperatures from -25°C to +30°C), has high reliability and consumes fuel with a moderate “appetite”. In half-load mode, gasoline consumption is about 1.6 l/h (thus, fuel in a fully filled 25-liter gas tank lasts for more than 15 hours - an impressive figure by the standards of equipment of this class). The motor is started by an electric starter, so users are spared the need to “exercise” every time they need to turn on the generator.

The mini-power plant produces a fairly “clean” current due to the fact that it is equipped with an automatic voltage regulator (AVR). But it should be noted that slight fluctuations in output voltage may be present (within normal ±10%). Therefore, if you plan to use this generator to power “capricious” consumers (such as, for example, many modern gas boilers equipped with very sensitive sensors), then you should also buy a good stabilizer. On the power station panel you can find a couple of connectors. One of them is a 32 A power outlet - the distribution panel of the house or equipment with high energy consumption (for example, powerful electrical equipment at a construction site) is connected to it. The adjacent connector is needed for the correct operation of the automatic transfer system. The fact is that this generator is equipped with an autostart module (ATS). Instantly reacting to the lack of voltage in the electrical network, it independently, in a fully automatic mode, starts the gas generator (or stops the engine when electricity appears). The panel also contains an ignition switch, a multi-function digital display and 12V output terminals from which the batteries can be charged. But there are no ordinary 230 V sockets for a standard plug at all.

If we take into account all of the above features and advantages (automatic start, reliable engine and long-term operation at one gas station), it becomes clear that the optimal “niche” for the Hyundai HHY7050FE ATS generator is to work as a backup power source for a private home, retail outlet or another object dependent on electricity.
