How To Choose A Power Generator

A power generator is a machine capable of converting a certain source of energy, mechanical, chemical, light or thermal, into electrical energy. These tools are very useful for those who frequent places where there is no electricity. Going on a camping holiday, organizing a fair, working in places where the electricity arrives badly, or simply providing an itinerant service, are activities that would be difficult, if not impossible, without using this device.

Power outages aren't famous for their good timing. This is a terrible feeling if you have only hauled up your fridge and also the power moves out, knowing that you've probably wasted money and lost meals for weekly. An emergency generator may avoid this stressful circumstance from occurring place, retaining your freezer and fridge functioning effortlessly.

There are different types of generators, different for: the fuel used to produce energy, the power delivered, the rotation speed, the frequency stability and the noise levels. So, how to choose the best electric generator 2020? First of all, you need to know the power required for use and select the type of fuel you prefer.

How To Calculate The Power Needed

Before orienting yourself on a specific choice, it is good to learn how to calculate the type of power that the current generator must deliver to power the instrument to be connected.

The power is measured in Watts and is given by the product of the consumption of the object and the inrush coefficient. The "consumption of the object" indicates the amount of energy in Watts consumed by the electronic instrument. The "starting coefficient" is the amount of energy in Watts necessary for the electronic device in the starting phase, ie in practice the power needed to start it, which is also the maximum current peak that the device can absorb. Once the calculation has been made, it is necessary to choose the generator with a wattage greater than or equal to the result obtained. For greater clarity of the concept here is a practical example:

Fuels Used

There are mainly three types of generators , based on the fuel used: petrol, diesel or LPG.

Petrol model

Ideal for occasional use, they are generally the cheapest generators. However, the initial expense is offset by the cost of fuel which is not too convenient. The petrol engine is able to work at very high levels, and is more complex than diesel engines, but this factor could lead to a breakdown of the appliance, subjected to greater effort. This type of fuel has the advantage of being easily available, but it must not be underestimated, it is an explosive and flammable material and storing it in cans can be dangerous.

Diesel model

Suitable for more intensive use thanks to the affordable fuel cost. The initial investment is certainly more demanding than gasoline generators, but in the long term the costs are greatly reduced. Diesel engines are more reliable and do not require too much maintenance, but they manage to perform a lower working regime. Diesel is a flammable material, but not explosive, which is why it is safer to keep in the tank even for medium-long periods. The only flaw is that devices of this type are noisier than those that use petrol.

Gas model

Less common, but undoubtedly with numerous advantages. Power costs are the lowest and at the same time the device is able to consume less fuel. This type of generating sets is also more ecological, with almost non-existent exhaust gases and not too unpleasant fumes emitted.

Rotational Speed And Frequency Stability

Depending on the use that must be made of the generator, it is good to choose it carefully also based on two other parameters: the rotation speed and frequency stability. The speed of rotation, or simply the revolutions that the engine can complete in one minute, is measured in RPM. Generators at 60 Hz typically operate at rotational speeds between 1800 and 3600 RPM, while those at 50 Hz work at speeds between 1500 and 3500 RPM. The 1800 RPM devices are more complex and structurally larger, four-pole machines suitable for more intensive and continuous use over time. The 3600 RPM generators, on the other hand, are two-pole, simpler appliances that require less maintenance. If you want to use the current generator is occasional and not very intense, these machines are the most suitable.

If there is the need to power a computer, a stereo, or any instrument with an electronic board, be careful, because they could be damaged. The current that is supplied by a generator is not as stable as the domestic one. Choosing a device with Inverter technology is advisable in these cases. The inverter is able to control and quantify the energy delivered, in order to accelerate or minimize the power required. It also optimizes the operation of the generator and reduces its consumption.
