There are quite a number of options for the home owner and business operator when you need to choose a generator: so many, in fact, that it can be very confusing to the uninitiated. What source of fuel do you prefer – diesel or petrol? Do you need a small “emergency” generator for use in the home, or one with plenty of power to act as a back up when the mains electricity fails in your business? If you don’t have much knowledge as to how portable generators work, you will find it difficult to choose.
How then, do you make a selection? To begin with, you should investigate for what exact purpose you will need the generator, as this will help you to determine the capacity. If you need a honda generator for home use, it would not be a good idea to choose a heavy duty industrial generator, as it would supply more power than you really need. Similarly, if your requirement is to run machinery, a small generator will not be sufficient as it is guaranteed 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, wherever you may need a portable and reliable source of energy. This can be because there is no mains power (as with construction sites) or the mains power cannot always be relied upon (agricultural areas and factories).
When you are working out your generator needs, you should opt for the most efficient model. The size of the new diesel generators is indicated by the output and speed given by the manufacturer: usually, a more powerful generator has a higher output and speed. Most generators can be categorised between an output of 5KVA (kilovolt-ampere units) and 2500KVA. The generators with lower KVAs can be used in the home, whereas the more powerful 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 calculate the load you need to supply. To do this, you just have to work out the power demand, whether this be for home or business use, during normal operating conditions. The amount of power that the generator is capable of providing will tell you whether it is powerful enough to meet the requirements of your home or business: the amount of fuel the tank carries only indicates how long the generator will operate between refueling.It is always a good idea to choose a generator that can provide a little more power than you really need, thus reducing the chances of overloading.
Another factor you will have to consider 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 select a silent diesel generator as the decibel level of these is considerably less than traditional diesel generators. It is also sensible to opt for 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 wee small hours. The decibel output is not such an important 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 purchase a good quality used generator, as this will cost far less.
Having a new diesel generator at hand 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 a brilliant idea. However, it pays to to do your research and carefully choose a generator that best suits your individual requirements.
