How then, do you make a selection? To begin with, you should investigate for what exact 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 your requirement is to run machinery, a small generator will not be sufficient as it is likely to fail when you need it most.
Diesel and petrol generators operate in a similar way. Diesel electrical generators are most often found in agricultural environments, on construction sites and in factories and warehouses: in fact, wherever you may need a portable and reliable source of energy. This is usually because there is no mains power (as with construction sites) or the mains power is unreliable (agricultural areas and factories).
In determining your generator requirements, you have to by necessity select the most efficient model. The size of thesilent generators is indicated by the output and speed provided by the manufacturer: it is usually the case that a more powerful generator has a greater output and speed. Most generators fall between an output of 5KVA (kilovolt-ampere units) and 2500KVA. The generators with lower KVAs are best for home use, whereas the higher ones are more than ample for the majority of industrial applications.
The model's efficiency rating is the initial step: however, it is also necessary to determine the load you have to supply. To do this, you just have to work 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 sufficient to meet the requirements of your home or business: the capacity of the fuel tank only indicates the number of hours the generator will operate between refueling.It is always a good idea to choose a generator that can supply a little more power than you really need, thus reducing the eventuality of overloading.
Another factor you may have to consider is the noise level of the portable generator. Will you need the generator to be run during the night in the home? If this is so, you should choose a silent diesel generator as the decibel level of these is significantly less than traditional diesel generators. It is also wise to choose a silent diesel generator with a large fuel tank, to guarantee that it runs overnight, thereby avoiding refueling in the middle of the night. The decibel output is not such important point if it is used in an industrial situation, or during the day.
If the generator is to be used only occasionally, it makes sense to purchase a good quality second hand 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 even when there is no existing mains electricity (camping is one such example) is good idea. However, you have to do your research and carefully choose a generator that best suits your individual requirements.
