How then, do you make a selection? To begin with, you should decide for what exact purpose you will need the generator, as this will help you to determine the capacity. If you need a generator for home use, it would not be a good idea to choose a heavy duty industrial generator, as it would give out more power than you really need. Similarly, if you need to run machinery, a small generator will not be enough as it is likely to fail when you need it most.
Diesel and petrol generators operate in a similar way. Diesel electrical generators are quite often found in agricultural environments, on construction sites and in factories and warehouses: in fact, anywhere there is a requirement for a portable and reliable source of energy. This can be due to the absence of mains power (for example construction sites) or the mains power cannot always be relied upon (agricultural areas and factories).
When you are working out your generator needs, you have to by necessity select the most efficient model. The size of the silent generator is indicated by the output and speed provided by the manufacturer: it is usually the case that, a more powerful generator has a higher output and speed. Most generators fall between an output of 5KVA (kilovolt-ampere units) and 2500KVA. The generators with lower KVAs can be used in the home, whereas the higher ones are more than ample for the majority of industrial applications.
The efficiency of the model is the initial step: however, you will also have to calculate the load you need to supply. To do this, you just have to calculate 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 needs of your home or business: the capacity of the fuel tank only indicates the number of hours the generator will operate between refueling.You should always choose a generator that provides a little more power than you really need, thus reducing the possibility of overloading.
Something else you may need to give some thought to is the noise output of the portable generator. 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 decibel level of these is considerably lower than than traditional diesel generators. It is also sensible to choose a silent diesel generator with a large fuel tank, to ensure that it runs overnight, thereby avoiding refueling in the middle of the night. The decibel level is not such a critical factor if it is used in an industrial situation, or in daylight hours.
If you only need to use the generator occasionally, it makes sense to buy a good quality used generator, as this will cost far less.
Having a honda generator at hand 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 a brilliant idea. However, it pays to to do your homework and carefully choose a generator that best suits your individual needs.
