There are many options for the home owner and business operator when the time comes to choose a generator: so many, in fact, that it can be quite problematic to the uninitiated. What type of fuel would you rather use - diesel or petrol? Is your requirement for 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 is not working in your business? If you don't have much of an understanding of how generators work, it could be very hard for you to choose the best one for your needs.

How then, do you make a selection? Firstly, you should investigate for what exact purpose you will need the generator, as this will help you to determine the capacity. If you require a generator for around the home, it would not be wise to choose a heavy duty industrial generator, as it would supply more power than you actually 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.

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 fact, anywhere there is a need for a portable and reliable source of energy. This can be because there is no mains power (as with building sites) or the mains power cannot be relied upon (agricultural areas and factories).

In determining your generator requirements, you need to choose the most efficient model. The size of the portable generators is specified by the output and speed provided by the manufacturer: usually, a more powerful generator has a higher output and speed. Most generators range between an output of 5KVA (kilovolt-ampere units) and 2500KVA. The lower KVA generators can be used in the home, whereas the higher ones are more than ample for most industrial applications.

Choosing the efficiency of the model is the first step: however, it is also necessary to calculate the load you need 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 is able to provide will indicate to you whether it is sufficient to meet the demands of your home or business: the amount of fuel in the tank only determines the length of time the generator will operate between refueling.It is always a good idea to opt for a generator that can provide you with a slightly higher level of power than you require, thus reducing the chance of overloading.

Another important aspect you will have to consider is the noise level of the buy silent generators. Does the generator need to be run during the night in the home? If so, you should select a silent diesel generator as the noise level of these is considerably lower than traditional diesel generators. It is also sensible 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 level is not such an important aspect 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 cost far less.

Having a generator available for emergency situations, such as natural disasters or power outages, or even when there is no actual mains electricity (camping is one such example) is good idea. However, it pays to do your research and carefully choose a generator that will work best when considering your individual needs.
