Buying a generator is an investment that can guarantee energy independence in the event of a power failure or unstable power supply. These devices are extremely useful both at home and in the company, but choosing the right model requires considering several key issues. Today you will learn which generator to choose, what parameters are most important and what to look for when buying.
One of the most important factors to consider is the power of the generator. Choosing the right power depends on the total energy demand of the devices you intend to power. Before purchasing, you should add up the power of all the devices that will be connected to the generator. The power value given on the nameplate of each device will help you make precise calculations.
However, it should be remembered that some devices, especially those with electric motors, may require more power when starting. Therefore, it is recommended to add about 20-30% of power reserve to the total. Thanks to this, the generator will not be overloaded. It is also worth considering whether you plan to power only basic devices, such as a refrigerator and lighting, or more demanding receivers, such as heat pumps or industrial equipment in the company.
Another important parameter is the type of generator – single-phase or three-phase. Single-phase generators operate at 230V and are suitable for powering basic household appliances, such as lighting, refrigerators, or smaller electrical tools. This is a good solution for people who need to protect basic household equipment.
In turn, a three-phase generator operates at a voltage of 400V and is necessary for larger facilities, such as large homes or companies. Three-phase generators are capable of powering devices with higher power, such as electric furnaces, induction hobs, or industrial machines. When deciding on a generator, it is worth checking what receivers you plan to connect and what voltage will be needed.
Generators are available in several power options: petrol, diesel and liquefied petroleum gas (LPG). Each type has its advantages that are worth considering.
Gasoline generators – are most often chosen due to their versatility and relatively low purchase price. They are an excellent solution for home applications where long-term power supply is not required. The advantage is the ease of starting and fuel availability, but gasoline consumption is higher than in the case of diesel.
Diesel generators – are more fuel efficient and therefore cost effective in the long run. They burn less fuel than their petrol counterparts, making them ideal for use in companies where power must be long-lasting and reliable. However, they are more expensive to purchase and generate more noise.
LPG gas generators – they are the cheapest option in operation. LPG fuel is cheaper than petrol and diesel, but the purchase of such a generator can be higher. They are also ecological, which can be a significant factor in places where low emissions are important.
Another important aspect is the fuel tank capacity. Generators with a larger fuel tank can operate for longer without having to refuel. This is important if the generator is to power a home or business for a longer period of time, such as during a long power outage. Smaller tanks, on the other hand, are better if the generator is to be transported frequently or used sporadically, such as in summer cottages.
For those who plan to power devices sensitive to voltage fluctuations, such as televisions, computers or medical equipment, an AVR voltage regulator is an essential element of the generator. Thanks to the AVR, the generator provides a stable output voltage, which protects delicate devices from damage caused by voltage surges. This is especially important in homes where advanced electronics are used.
If you want your generator to operate quietly, it is worth considering buying a model with a built-in soundproof housing or anti-vibration system. These solutions significantly reduce noise, which is important, especially if the generator is to be installed close to the house. Models such as the Pramac generator, available in our offer, combine high efficiency with relatively quiet operation, making them an ideal choice for homes and businesses.
In order to choose the right generator, it is worth considering what devices will be powered and how long the generator will work. If you are looking for a device for temporary power failures, a smaller single-phase generator will be sufficient. In the case of companies or larger facilities, it may be necessary to buy a three-phase generator with higher power, but due to its parameters, it will also require a special offer. Check out our offer of generators and see if it is worth buying a generator for your home or company.
