An inverter generator (5 kW, diesel) is a combination of the appropriate type of motor with an electric transformer for automated power generation. Mostly devices are used where the local power grid is not available, for example, in summer houses and in country houses.
A 5 kW diesel generator with auto start can be made both in the form of a portable installation, and in a stationary casing, open and closed versions. Let us consider in more detail the device and its individual models.
Operating principle
In diesel generators, after filtration, clean air enters under high pressure. At the same time, fuel flows from the nozzle. Air is mixed with fuel, and the finished mixture is directed along the piston, compressing. With increasing temperature, the volume decreases, and ignition occurs. If this does not happen, then the motor is turned on through the operation of the air filter and the automatic transfer switch. When igniting diesel fuel, the mixture expands, which pushes the piston mechanism down.
Engine control is provided by mechanical and automatic (electronic) speed controllers. The latter have a closed loop and are equipped with sensors that determine the corresponding speed.
Fuel calculation
Before buying these devices, owners are often interested in diesel consumption. In the calculation, the manufacturer of the mechanism should be taken into account: the Honda diesel generator (5 kW), Hyundai, Kipor, North, Champion and so on will have different indicators. The body volume and oil consumption are also taken into account.
The operation of a low-power diesel generator is calculated in g / kW * h. Thus, in one hour of operation a certain amount of grams of fuel is consumed. The calculation of power is based on the characteristics of the device. But ready-made data can be obtained by looking at his passport.
Connection
A 4.5 kW diesel generator is connected in several ways. First, all household appliances in the house are checked.
A 5 kW “Foreman” diesel generator (reviews of the owners confirm this) is capable of serving both single-phase power household appliances and welding machines designed for construction work. When choosing a model, pay attention to those devices that can be connected to it. Having determined all household appliances, in the instruction manual they find information about what power is needed for the continuous operation of the mechanism.
Wires are selected (the Star scheme is most often used). In addition, all the necessary components are purchased:
- switch;
- flexible cable;
- plug-in to enter the socket;
- junction box ;
- warning lamp.
Connection is as follows:
- the generator is set up and connected to a home electricity system;
- a switch is mounted on the wall next to the distribution window;
- connect the switch and box;
- connect the power wires of the house to one end of the switch, and a flexible cable to the other;
- the cable is passed to the location of the generator;
- plug it into a socket;
- fix the flexible cable to the plug, and the other end to the connector connected to the generator.
The indicator should be connected. Then it will be seen that the energy of the local network is available.
When choosing a specific model, it is worth familiarizing yourself with the reviews that device owners leave. In addition, model updates are possible, which also brings with it a change in technology. An individual wiring diagram is selected for different devices. The conductor cross-section and voltage must be taken into account.
The SKAT devices have good characteristics. We will study them in more detail.
5 kW generator (diesel) "SKAT"
The models under consideration are based on a four-stroke engine. These are reliable compact and high-speed devices that are able to work in heavy conditions.
Thanks to the optimal volume of silencers and the use of sound insulation, they differ in their operation by low noise and vibration. Minimal harm from exhaust gases is achieved due to a special form of air flow in the combustion chamber, due to which the fuel is intensively mixed with oxygen.
The 5 kW generator (diesel) SKAT is equipped with a Boshc injection system, with which fuel economy reaches up to fifteen percent, and the best Japanese NSK bearings. A large sectional copper winding made of primary copper provides the plants with a long working life.
In addition, there is electrical protection against overload and from reduced oil levels. When these cases occur, the mechanism automatically turns off. If starting is carried out at low temperature, a heating system is provided.
Consider the differences between individual models of SKAT generators.
UGD-5300E, UGD-5300EK and UGD-5300ET - the main differences
UGD-5300E is a diesel generator with automatic start.
A metal casing is added to UGD-5300EK (indicated by the letter "K"). Due to this, the noise during operation of the device is reduced. Therefore, it is quite possible to install it near residential premises. The casing provides protection. With it, the device becomes more resistant to weather anomalies, physically more durable, and direct contact with a hot muffler is excluded.
UGD-5300ET is a three-phase generator, which makes it possible to connect powerful energy consumers to 380 V.
Do I need a three-phase generator or should I stop at a single-phase?
Three phase or single phase installation?
It often happens that equipment does not need standard 220 V, but 380 V. For example, in a construction site, such devices are machines, pumps, concrete mixers and others. Also, for example, in a car wash, the washer has an output of 380 V.
In such cases, of course, it is better to purchase a three-phase 5 kW generator - diesel. It is more universal, since it has an output of 220 V. Moreover, it should be borne in mind that when connecting single-phase devices to a three-phase generator, its power can be removed only by one third. And in all three phases, the load should be distributed equally, so that the phase imbalance does not turn out.
