If you need to choose a generator, whether it is for home or industrial use, there are many possibilities: so many, in fact, that it can be quite confusing to those without the necessary knowledge. What type of fuel are you going to use – diesel or petrol? Do you need a small “emergency” generator for the home, or do you need one with an abundance of power to act as a back up when the mains electricity is not reliable in your business? If you don’t have sufficient understanding of how generators work, you will find it difficult to choose.
How then, do you make this necessary choice? As a first step, you should work out for what actual role you will need the generator, as this will help you to determine the capacity. If you require a generator for home use, it is not necessary to choose a heavy duty industrial generator, as it would provide much more power than you require. Similarly, if you need to operate 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 most 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 can be due to the absence of mains power (as with construction sites) or the mains power cannot be relied upon (such as with agricultural areas and factories).
In determining your generator requirements, you need to opt for the most efficient model. The size of the petrol generators is specified by the output and speed provided by the manufacturer: usually, a more powerful generator has a higher output and speed. The majority of generators fall between an output of 5KVA (kilovolt-ampere units) and 2500KVA. The lower KVA generators are suitable for home use, whereas the higher ones provide more than enough power for most industrial applications.
The model’s efficiency is the first step: however, it is also necessary to calculate the load you need to supply. To do this, you simply have to calculate the power demand, whether this be in the home or the business, during normal operating conditions. The amount of power that the generator is able to provide will indicate whether it is adequate 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.It is always a good idea to choose a generator that provides a little more power than you require, thus reducing the chances of overloading.
Another factor you may have to give some thought to is the noise level of the diesel generators. Does the generator need to be run during the night in the home? If this is the case, you should choose a silent diesel generator as the decibel level of these is much much reduced when compared to traditional diesel generators. It is also sensible to choose a silent diesel generator with a large fuel tank, to make sure that it runs overnight, so you don’t have to be worried about refueling in the middle of the night. The noise level is not such a problem if it is used in an industrial situation, or during the day.
If the generator is to be operated only occasionally, it makes sense to look for a good quality used generator, as this will save you a significant amount of money.
Having a generator avaiable for emergency situations, such as natural disasters or power outages, or even 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.
