There are quite a number of options for the home owner and business operator when the time comes to choose a generator: so many, in fact, that it can be quite confusing to those who do not have the knowledge. What source of fuel do you prefer - diesel or petrol? Do you need a small "emergency" generator for the home, or one with a great amount of power to act as a back up when the mains electricity fails in your business? If you don't have much of an understanding of how generators work, you will find it difficult to select one.

How then, do you make a selection? To begin with, you should decide for what precise purpose you will require the generator, as this will assist you in determining the capacity. If you require a generator for home use, it would not make sense to choose a heavy duty industrial generator, as it would supply more power than you actually need. Similarly, if you need to run machinery, a small generator will not be sufficient as it is likely to fail when you need it most.

Both diesel and petrol generators are similar in how they deliver power. Diesel electrical generators are quite often found in agricultural environments, on construction sites and in factories and warehouses: in fact, anywhere there is a need for a portable and reliable source of energy. This is usually because there is no mains power (as with construction sites) or the power supply is unreliable (agricultural areas and factories).



In determining your generator requirements, you should choose the most efficient model. The size of the petrol generator is indicated by the output and speed given by the manufacturer: generally speaking, a more powerful generator has a higher output and speed. Most generators range between an output of 5KVA (kilovolt-ampere units) and 2500KVA. The lower KVA generators are suitable for home use, whereas the higher ones are more than ample for most industrial applications.

The efficiency of the model is the first step: however, you will also have to calculate the load you have to supply. To do this, you simply have to calculate the power demand, either for the home or the business, during normal operating conditions. The amount of power that the generator is able to provide will indicate to you whether it is sufficient to meet the demands of your home or business: the amount of fuel in the tank just determines how long the generator will operate between refueling.It is always sensible to choose a generator that provides a little more power than you absolutely need, thus reducing the chance of overloading.

Another factor you may have to consider is the decibel level of the new portable generators. Will you be required to run the generator during the night in the home? If so, you should choose a silent diesel generator as the noise output of these is much lower than traditional diesel generators. It is also sensible to choose a silent diesel generator with a decent sized fuel tank, to ensure that it runs overnight, thereby avoiding refueling in the middle of the night. The decibel output is not such a problem if it is used in an industrial situation, or during the day.

If you only need to use the generator occasionally, it makes sense to buy a good quality second hand generator, as this will cost far less.

Having a generator available for emergency situations, such as natural disasters or power outages, or perhaps those times when there is no mains electricity (camping is one such example) is an excellent idea. However, you should conduct some research and carefully choose a generator that best suits your individual requirements.
