Selecting A Generator - Which Will Suit Your Needs?

E-mail Print PDF
There are quite a number of options for the home owner and business operator when you need to choose a generator: so many, actually, that it can be quite confusing to the uninitiated. What type of fuel do you prefer - diesel or petrol? Do you need a small "emergency" generator for 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 of an understanding of how generators work, you will find it difficult to select one.

There are quite a number of options for the home owner and business operator when you need to choose a generator: so many, actually, that it can be very confusing to those who do not have the knowledge. What type of fuel do you prefer - diesel or petrol? Do you need a small "emergency" generator for the home, or one with a great amount 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 generators work, you will find it difficult to select one.

How then, do you make a choice? To begin with, you should decide for what precise purpose you will need the generator, as this will help you to determine 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 enough 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 usually found in agricultural environments, on construction sites and in factories and warehouses: in reality, anywhere there is a requirement for a portable and reliable source of energy. This can be because there is no existing mains power (as with construction sites) or the mains power cannot be relied upon (agricultural areas and factories).

When you are figuring out your generator requirements, it is important to choose the most efficient model. The size of the portable generators is indicated by the output and speed provided by the manufacturer: in the majority of cases, a generator with more power has a higher output and speed. The majority of generators fall between an output of 5KVA (kilovolt-ampere units) and 2500KVA. Those generators with a lower KVA rating are suitable for home use, whereas the higher ones are more than powerful enough for most industrial applications.

The efficiency of the model is the first step: however, you will also have to calculate the load you have to supply. To do this, you simply have to work out the power demand, whether this be in the home or the business, during normal operating conditions. The amount of power that the generator can output will tell you whether it is sufficient to meet the requirements of your home or business: the capacity of the fuel tank only indicates how long the generator will operate between refueling.You should always choose a generator that can supply a little more power than you require, thus minimising the chances of overloading.

It may also be necessary to consider the decibel output of the new diesel generators. Does the generator need 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 purchase a silent diesel generator with a big enough fuel tank, to guarantee that it runs overnight, thereby avoiding refueling in the middle of the night. The decibel output is not such a critical aspect if it is used in an industrial situation, or during the day.

If the generator is to be used infrequently, it makes sense to choose a better quality used generator, as this will save you a good deal of money.

Having a generator at hand 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, you have to do your research and carefully choose a generator that will work best when considering your individual requirements.
