The best diesel generators with a power of 6 - 7 kW

The QUBE QFED8500S3 diesel generator is designed taking into account the characteristics of operation in public places and is capable of withstanding a peak load of up to 6.5 kW. The protective casing significantly reduces noise from the engine (74 dB), providing comfortable conditions when creating an integrated backup power supply for a private home, store, cafe, and government agencies. The weighty unit is easy to move thanks to its wheelbase, and anti-vibration cushions reduce noise and load on the chassis. The fuel tank holds 15 liters, so even at maximum load (consumption 2.38 liters), autonomous operation will be at least 6 hours. Starting is done using an electric starter by simply turning the key.

The alternator has a copper winding, which is not subject to excessive heating and oxidation. The generated energy eliminates interference, and the device can operate around the clock without failures throughout its entire service life. It is also worth noting the presence of voltage stabilization (AVR). The generator is equipped with sockets with output voltages of 230 V and 400 V, as well as terminals for 12 V equipment. There is an indication of the oil level in the crankcase and automatic shutdown at critical values, which prevents wear of moving engine parts.

The EnerSol SKDS-7EBAU diesel generator is suitable for organizing comprehensive backup power for commercial and household consumers. The reliable motor and copper alternator cope with loads of up to 6.5 kW at peak and produce a stable output voltage thanks to the automatic stabilization system (AVR). Energy generation occurs in two modes - 230 V or 400 V, and switching is carried out by a toggle switch on the panel. The user can connect both powerful equipment (jackhammer, heat gun, freezers, electric heating) and home appliances (PC, router, refrigerator, TV, vacuum cleaner). There is one 32A outlet for each power system, and the 12V line is implemented using terminals.

The generator is equipped with everything necessary for ease of use. The design includes a powerful metal frame and wheels for movement. The casing is supplemented with acoustic panels from the inside, so the noise level does not exceed 72 dB. The manufacturer has provided the connection of an automation unit (ATS) for automatic start when the main power supply is turned off. The backlit display makes it easy to control parameters at any time of the day, and built-in automation prevents failure due to overload. It is worth noting that the exhaust pipe is not located very well directly next to the transport handle, which increases the likelihood of burns.

The Konner&Sohnen KS 9100HDE-1/3 ATSR electric generator belongs to the Heavy Duty series, which is known for its high quality. The equipment is designed for long-term continuous loads and has a long life cycle (about 3000 operating hours). The model boasts a low weight (122 kg) as for diesel engines, but even with this indicator it is more suitable for stationary use, since there are no wheels for transportation. Use outdoors is allowed, including during rain, but only under a canopy and subject to reliable protection from direct water ingress. The generator is equipped with a 30 Ah battery, which provides easy starting with an electric starter, as well as automatic activation when installing an additional ATS unit. There is a function for warming up the engine in winter. It is important to note that the Konner&Sohnen KS 9100HDE-1/3 ATSR complies with the EURO V environmental standard.

The model operates in different modes, so it is suitable for home, commercial activities, and government agencies. The system successfully operates with three-phase (400 V) and single-phase (230 V) networks, car equipment (12 V), guaranteeing sufficient power for household, construction, medical, office and other equipment. The rated load is 6 kW for 230 V and 7 kW for 400 V. Stable output indicators are ensured by the built-in auto voltage regulator (AVR). The open, shroudless design improves heat dissipation but increases noise levels (96 dB).

The Konner&Sohnen Heavy Duty KS 9200HDES-1/3 ATSR diesel generator offers a number of thoughtful technical solutions that help with regular power outages in a private home and maintain the functionality of equipment in a store, office, or warehouse. The advantage of the device is the metal anti-vandal casing, which protects against splashes of water, dust, foreign objects, injuries and can significantly reduce the noise level (69 dB). The electric generator can be used both indoors (if there is good ventilation) and outdoors under a canopy. Ease of movement is guaranteed by rubberized wheels and handles on both sides. The exhaust is mounted vertically, so it can heat up the carrying handle and also increases the likelihood of getting burned.

Konner&Sohnen KS 9200HDES-1/3 ATSR Heavy Duty series is optimally suited for operation in conditions of frequent power outages. The branded engine and alternator are balanced in power, have an extended service life and are capable of powering equipment for various purposes. A 400 V line will be appropriate for the most “gluttonous” devices and objects with a three-phase system (up to 7 kW), and a 230 V socket ensures the normal functioning of any household appliance (up to 6 kW) with minimal fuel consumption. Output current is automatically adjusted (AVR) to prevent voltage surges. The kit includes a set of tools, filters and a battery. The standard connector for the optional ATS does not limit the user in the choice of automation. Konner&Sohnen KS 9200HDES-1/3 ATSR complies with the EURO V standard and guarantees a minimum amount of harmful emissions.

The EnerSol SKDS-8EBAU diesel generator has good autonomy due to the enlarged tank (27 l). Despite the large engine volume (633 cm³), fuel consumption is about 2.45 l/h, which is enough for 11 hours of operation without refueling. Thanks to the metal casing with sound-absorbing pads, it was possible to reduce noise to a comfortable 72 dB, so the model creates a minimum of discomfort in public places. The design features ensure the protection of critical components, but also result in increased weight (221 kg), which makes the generator much more difficult to move, despite the presence of wheels.

The EnerSol SKDS-8EBAU electric generator is capable of ensuring the operation of almost any equipment. The motor and copper alternator are rated for loads up to 7.5 kW (8 kW peak), and the power supply includes a separate 400 V and 230 V outlet. An additional 12 V output is designed for charging car batteries. The control panel is intuitive and functional. There is an output for automation (ATS), a pre-heating button at low temperatures and overload protection systems. The generator has a built-in automatic output current regulation (AVR), which protects equipment from voltage surges. EnerSol SKDS-8EBAU is well suited for data centers and Internet providers where quick implementation of a backup supply plan is required.
