We immediately point out that this solution is for private homes, as it requires the generator to be placed outdoors due to its emissions. In addition, such a device produces noticeable noise, which will certainly not please your neighbors.

We choose a generator

When choosing a generator for a private house, first of all, you need to understand which features of this equipment are most important in your particular conditions:

• strength,
• mass,
• dimensions,
• working time,
• noise level,
• ease of starting
• the possibility of automatically entering the reservation,
• cost.

The power of the generator is the first thing to consider. Calculating the required power is simple: add up the power consumption of the electrical appliances to be powered. This information can be found on the information labels of your equipment. These are various heating devices, household appliances, lamps, etc.

But don’t get carried away because too much power and too little consumption will not be beneficial either. If you buy a generator with a large power reserve, but do not plan to give it a full load, it is important to understand that such an economical mode of operation leads to incomplete combustion of fuel, candles not burning. it becomes coated with soot more quickly and the engine oil needs to be changed much more often. For the same reason, only 30 minutes of “idling” no-load operation of a gasoline generator is allowed.

The result is as follows: you do not need to buy a 6 kilowatt generator to power the electric kettle and the light bulb.

To significantly extend its service life, you should take into account the required minimum load of the device – this is 20% of power in a gasoline engine and 25% in a diesel engine.

If you plan to operate the equipment only when a backup power supply is needed, and the consumers will only be household appliances, then a small 2.5 – 3.5 kilowatt power unit is suitable for this application. Consider that their nominal power will be equal to 2 – 2.5 kilowatts.

Gasoline or diesel

The engine is the central part of your future generator and its service life will depend on it. According to the type of fuel, engines can be divided into gasoline and diesel.

• Benefits diesel — More resources and lower fuel consumption compared to gasoline. But diesel generators are twice as expensive on average. A diesel power plant is suitable when a constant source of energy and long-term operation (from 8 hours a day) is required, or when a power of 10 kilowatts is required. Diesel power plants are characterized by durability and a large engine resource.
• Gasoline variants differ in lightness of the engine and lower cost. If the generator will be used as an emergency power source, it is better to choose a car with a gasoline engine. Gasoline generators require less time and simpler maintenance.

nuances

• Medical equipment and computers have special sensitive requirements for power supply: their operation requires a smooth sine current that only inverter-type generators can provide. They will provide the ideal quality of the current and allow you to connect the equipment directly (without a stabilizer).
• It is better if the units of the power plant such as rotor and stator have copper windings instead of aluminum. Copper conducts current better and has low thermal conductivity, as a result, the device heats up less during operation.
• Equipping the station with a voltage stabilizer at the output will be a plus. Its essence is reduced to voltage equalization when the engine revolutions change, which provides an equal power supply to heating appliances, lighting devices and conventional household appliances (TVs, washing machines and refrigerators).

automatics

In the presence of automation, the generator is started and stopped without human intervention. The device monitors the central network and starts working by itself when the voltage is cut off for more than 10 seconds. If voltage appears in the mains, the automation turns off the generator and goes into sleep mode.

So, which generator to choose for the home

Minimum power is sufficient with a standard set of electrical appliances 2 kilowatts. If you want all appliances in a 3-4 person house to work perfectly, choose an electric generator of at least 5 kilowatts. With it, you will close the need to provide energy to standard consumers.
