Choosing a diesel generator for a summer residence

Diesel generators for summer cottages are chosen in cases where it is necessary to provide heating of the room in the absence of power supply or other alternative sources of heat. About which one is better suited, what you should pay attention to when buying such equipment, you should learn more in detail before visiting the store. Indeed, today on sale there are household models on a diesel engine of 5, 8 kW and other power with low fuel consumption, as well as options suitable for short-term or permanent use.

A diesel generator for a summer residence is a compact source of energy that receives it from the combustion of liquid fuel... Its installation in a country house allows you to easily survive periods of power outages. Unit design consists from a supporting element - a frame, an engine powered by a diesel engine, an alternator needed to convert energy.

The choice of diesel fuel as a fuel is much more rational than the use of gasoline. It costs less, provides opportunities for operation in different modes, does not require complex maintenance. Household models usually have a power of 5 to 15 kW, are lightweight and compact. They generate a voltage of 210-230 V, sufficient for the stable operation of most electrical appliances.

All diesel generators are divided into household and industrial. The first ones generate single-phase current, they can provide long and stable operation without interruptions. Industrial models are much more powerful, provide a voltage of 380 V. They are really powerful, suitable for a constant supply of electricity to private homes.

Most three-phase diesel generators are rated at 5 kW or more. If the energy consumption is high, you can select options from 8 kW, with which you can work in the workshop, using powerful machines. All diesel generators can be called equipment with low fuel consumption - they spend 1.5-2 times less than gasoline counterparts, about 200 ml per 1 kW.

Compact low-power models are allocated in a separate category. ASU - autonomous generating sets. They have a power of no more than 5 kW, air-cooled engine. Such models are equipped with motors with a frequency of 1500 to 3000 rpm. Variants with the lowest rates are suitable for continuous and continuous operation. High-speed diesel engines for 3000 rpm / min are designed for intermittent use.

In addition, the equipment is divided into 2 categories according to the type of engine.

1. Asynchronous... It implies a faster rotation of the rotor relative to the stator, while it is directed in the same direction. This design of the motor implies less voltage leakage, requires a capacitor. Under extreme overload conditions, this technique is less reliable.
2. Synchronous... The rotation of the rotor and stator in such diesel engines occurs at the same frequency. Synchronous generators are more stable in operation, ensure the preservation of optimal parameters of the output voltage. Powerful machines, welding inverters can be connected to them.Synchronous models withstand overload better, are suitable for continuous operation.

The best diesel generators for a country house are produced by the world's leading manufacturers. Such equipment is reliable, there are no problems with its service. Among the current models in different power categories, you should pay attention to such.

• DDE DDG3300E. A compact model of a diesel generator, with which short-term power outages will not create problems. Power of 3.3 kW will be enough to maintain the operation of an electric stove, TV, refrigeration unit. The engine start is electronic, any person can cope with the control. The model is very economical, consumes a little more than 1 liter of fuel per hour, and is capable of operating up to 10 hours at 1 refueling.

• Hyundai DHY-6000 SE... Diesel generator from a well-known Korean manufacturer - "the golden mean" in terms of price and quality. Its power of 5.5 kW is enough for successful seasonal living in a country house. With a full tank of 17 liters, the model can work up to 9 hours non-stop. The model has a wheelbase, modern design, convenient control panel, soundproofed casing, but it cannot be called compact.

• Mitsu Power Eco ZM7000-DE... The Japanese-made air-cooled unit with an output power of up to 6 kW is suitable for summer cottages with permanent residence of people. The model has a solid frame, large transport wheels. The equipment is equipped with a copper alternator, capable of providing stable, uninterrupted operation without peak overloads.

• Daewoo Power Products DDAE 10000DSE-3. A powerful diesel generator to fully meet all the electricity needs of the country house and workshop. The built-in selector allows switching between single-phase and three-phase current supply, the equipment is capable of delivering up to 7.2 kW, while it operates almost silently.

To understand which diesel generator is best suited for a summer residence, a detailed consideration of all the most important criteria helps. These include the following.

1. Power consumption. On average, a diesel generator will operate at 40-75% of the specified rated power. For example, a 5 kW model will generate no more than 3 kW. If the load is too low, the equipment consumes fuel "idle", and if the load is too high, the efficiency drops. Before buying, it is worth calculating the approximate amount of upcoming energy consumption, determining the optimal power.
2. Fuel consumption... Indicators up to 200 ml for the generation of 1 kW are considered the norm.
3. Ergonomics and compactness of the case. The device should be easy to install and transport.
4. Noise isolation... Without it, the diesel generator in the country will work, making too loud sounds - over 75 dB.
5. Eco-safety. The less harmful the emissions into the atmosphere, the better.
6. Engine cooling method... For short-term use, models with an air system are suitable. For a constant supply of electricity, options with a liquid-cooled engine are better suited.
7. Availability of automation. It is mandatory for three-phase technology and models used for continuous continuous operation. Even the simplest diesel generator must have overheating protection sensors to avoid a fire.
8. Duration of continuous work. There will be enough equipment for the dacha, designed for 12 hours of non-stop operation.
9. Fuel tank volume... For continuous use, models with indicators from 8-10 liters are suitable. A small tank volume will require regular refueling.

Considering all these points, you can find an inexpensive and reliable diesel generator that can provide periodic or constant power supply in a country house.
