How to Select A Generator Which Will Suit Your Requirements?

There are many options for the home owner and business operator when the time comes to choose a generator: so many, actually, that it can be quite confusing to the uninitiated. What source of fuel do you prefer – diesel or petrol? Do you need a small “emergency” generator for the home, or one with sufficient power to act as a back up when the mains electricity is not working 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 choice? Firstly, you should investigate for what exact purpose you will require the generator, as this will assist you in determining the capacity. If you need a diesel generator for home use, it would not be wise to choose a heavy duty industrial generator, as it would provide more power than you really need. 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 have similar power delivery. 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 (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 portable generators is specified by the output and speed given by the manufacturer: usually, 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 can be used in the home, whereas the higher ones are more than ample for most industrial applications.

The model’s efficiency rating is the initial step: however, it is also necessary to determine the load you need to supply. To do this, you simply have to work out the power demand, whether this is in the home or the business, during normal operating conditions. The amount of power that the generator is capable of providing will tell you whether it is sufficient to meet the needs of your home or business: the the amount of fuel the tank holds 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 chances of overloading.

Something else you may need to give some thought to is the noise output of the new diesel generators. Will you be required to run the generator during the night in the home? If this is the case, it is a good idea to choose a silent diesel generator as the decibel level of these is considerably much reduced when compared to than traditional diesel generators. It is also a good idea to choose a silent diesel generator with a large fuel tank, to guarantee that it runs overnight, so you don’t have to be worried about refueling in the middle of the night. The decibel output 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 purchase a good quality used generator, as this will save you a significant amount of money.

Ensuring that you have a diesel 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 an excellent idea. However, it pays to to do your homework and carefully choose a generator that best suits your individual requirements.
