Generators

Generators – for homes, farms and businesses

Given the current instability in Ukraine, the ability to maintain the operation of vital systems and businesses is becoming critical. Petrol generators, diesel generators and inverter generators are capable of providing uninterrupted power supply. Generators become particularly relevant in conditions of low temperatures.

A generator is a stand-alone device. It is designed to convert mechanical energy produced by an engine into electrical energy. Its main function is to create a backup or permanent power source that is independent of the centralised grid.

Modern generators perform a number of critically important functions. They power household appliances, lighting, heating boilers, pumps, refrigeration equipment, as well as office and industrial equipment. In conditions of complete absence or frequent power outages, a generator becomes the only way to maintain the functioning of a household and the continuity of business processes.

Types of generators

Choosing a specific model begins with understanding the differences between the main types of generators, each of which has its own operating characteristics.

Petrol generators are among the most popular on the market due to their affordability and ease of use. If you decide to buy a petrol generator, you will get compact equipment that is ideal for private use where short-term backup power is required:

• Advantages — low initial price, easy start-up even at low temperatures, compactness and mobility.
• Disadvantages: higher fuel consumption compared to diesel generators, shorter engine life, prone to overheating during prolonged continuous operation (requires regular breaks), needs to be protected from precipitation.
• Power and operating time: power ranges from 0.35 to 30 kW. The average continuous operating time is 4–10 hours.

The catalogue features a variety of petrol generators for all needs.

A diesel generator is the choice for those who need a long-lasting and powerful power supply. It is particularly suitable for businesses or large private homes:

• Advantages — high engine life (capable of operating for hundreds of thousands of hours), low fuel consumption (savings on operation). Ability to operate without stopping for 10-20 hours or more.
• Disadvantages — higher price, sensitivity to low temperatures (may require preheating to start).
• Power and operating time — power range is 5–50 kW and above. Operating time exceeds 10 hours on a single tank.

A diesel generator will provide energy to the most demanding facilities. If you need to buy a diesel generator for an industrial facility, pay attention to medium-power models. For example, buying a 5 kW diesel generator is the optimal solution for powering a house or small workshop.

An inverter generator is the pinnacle of technological excellence among compact power sources. They produce perfectly clean sinusoidal current, which is critical for sensitive electronics:

• Advantages — high current quality (stable voltage), low weight, economy (speed is regulated according to the load). Low noise level, built-in overload protection.
• Disadvantages: limited maximum power (rarely exceeding 7 kW), higher price compared to classic models.
• Power and operating time: 0.5–7 kW. Operating time: 3–10 hours, depending on the load.

A high-quality inverter generator is a must for powering sensitive equipment. Looking for a compact and efficient model? A 3 kW inverter generator provides power for most household appliances.

Generator comparison table

The table below contains comparative characteristics that will help you quickly assess the advantages and disadvantages of each type of generator.

Each type of generator offers a unique combination of characteristics that make it suitable for specific tasks. By paying attention to these parameters, you will be able to make an informed choice.

Types of generators by purpose

The choice of power and type of generator directly depends on the object it is to power. For an apartment, it is better to choose inverter generators (1-3 kW) because of their quiet operation and compact size. They are capable of powering lighting, a router and a boiler. For a private house of average size, the optimal solution would be to buy a 3-5 kW generator (petrol or inverter) for the home, which will be sufficient for basic comfort: refrigerator, light, pump, TV.

The business sector requires greater reliability and long operating times. For a small office or café, 5–10 kW models are suitable. If you need a powerful generator for a business (restaurant, manufacturing, supermarket) where continuous operation for many hours is critical, consider diesel generators or complete installations with a capacity of 10 kW and above.

Remember that appliances with electric motors (refrigerators, pumps, compressors, air conditioners) have high starting currents. Their peak power can be 2-3 times higher than the nominal power. Make a list of all the appliances that need to run simultaneously. Add up their rated power and increase the total by 20-30% for reserve and to compensate for starting currents.

How to choose a generator?

Which generator should you buy for your home? The selection process requires attention to many factors that will determine the efficiency and durability of the equipment:

1. Power (kW) is the most important parameter. For basic power supply to a house or flat, 2–4 kW is sufficient. For powering a poultry house, farm or small business with refrigeration equipment, you should aim for 5–15 kW. Always buy a generator with a power reserve of 20–30%.
2. Continuous operating time depends on the type of cooling (air or liquid) and the tank volume. Air-cooled petrol models require breaks every 4-8 hours. Liquid-cooled diesel models can run continuously for up to 20 hours or more.
3. Operating conditions — Single-phase/Three-phase. Single-phase (230 V) is the standard for most household appliances. Suitable for home, office, and café use. Three-phase (400 V) is necessary if you have powerful industrial motors, pumps or other equipment designed for 380 V. If a three-phase generator powers only single-phase appliances, it is important to ensure an even load on each phase.
4. Mobility — for temporary or mobile use (construction, recreation), choose lightweight petrol or inverter generators with wheels. Stationary (often diesel) models are suitable for permanent backup power.
5. Noise — its level is critical, especially in residential areas or premises. Inverter generators and diesel models in a noise-proof enclosure operate much more quietly (50–70 dB) compared to open petrol models (75–95 dB).

Diesel generators are the most economical in the long term. Inverter models regulate engine speed according to the actual load. Choose models with protection functions: low oil level, overload and short circuit.
