There are quite a number of options for the home owner and business operator when you need to choose a generator: so many, actually, that it can be quite confusing to the uninitiated. What type of fuel do you prefer – diesel or petrol? Do you require 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 is not available to your business? If you don’t have much of an understanding of how generators work, you will find it difficult to choose.
What is the best way to choose? To begin with, you should decide for what precise purpose you will need the generator, as this will help you to determine 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 provide more power than you require. Similarly, if your requirement is to run machinery, a generator with a low output of power will not be sufficient as it is bound to fail when you need it most.
Both diesel and petrol generators provide power in similar ways. Diesel electrical generators are usually found in agricultural environments, on building sites and in factories and warehouses: in fact, anywhere there is a requirement for a portable and reliable source of energy. This can be because there is no existing mains power (as with construction sites) or the mains power is unreliable (agricultural areas and factories).
When you are figuring out your generator requirements, you need to choose the most efficient model. The size of the buy silent generators can be worked out by the output and speed provided by the manufacturer: generally speaking, a more powerful generator has a higher output and speed. Most generators fall between an output of 5KVA (kilovolt-ampere units) and 2500KVA. The lower KVA generators can be used in the home, whereas the higher ones are more than ample for most industrial situations.
The model’s efficiency rating is the initial step: however, you will also have to calculate the load you have to supply. To do this, you just have to figure out the power demand, whether this is for home or business use, during normal operating conditions. The amount of power that the generator is able to provide will tell you whether it is powerful enough to meet the needs of your home or business: the capacity of the fuel tank only determines how long the generator will operate between refueling.You should always choose a generator that provides a little more power than you require, thus minimising the eventuality of overloading.
Another important aspect you will have to consider is the noise output of the new petrol generator. Does the generator need to be run during the night in the home? If so, you should choose a silent diesel generator as the noise output of these is much less than traditional diesel generators. It is also a good idea to choose a silent diesel generator with a large fuel tank, to ensure that it runs overnight, thereby avoiding refueling in the wee small hours. The noise output is not such an important factor if it is used in an industrial situation, or during the day.
If the generator is to be used infrequently, it makes sense to choose a good quality used generator, as this will save you a good deal of money.
Having a generator available for emergency situations, such as natural disasters or power outages, or perhaps when there is no existing mains electricity (camping is one such example) is an excellent idea. However, it pays to do your research and carefully choose a generator that best suits your individual requirements.
