How to Choose A Generator That Is Right For Your Needs
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” silent generator for the home, or one with a great amount of power to act as a back up when the mains electricity is not available to your business? If you don’t have much knowledge as to how new diesel generators work, you will find it difficult to choose.
How then, do you make a choice? 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 require a generator for home use, it would not be wise to choose a heavy duty industrial generator, as it would give out more power than you actually need. Similarly, if your requirement is to run machinery, a small generator will not be enough as it is guaranteed to fail when you need it most.
Both diesel and petrol generators have similar power delivery. Diesel electrical generators are most often 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 construction sites) or the mains power cannot always 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 determined by the output and speed given by the manufacturer: it is usually the case that, a more powerful generator has a higher output and speed. The majority of 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 model’s efficiency rating is the first step: however, it is also necessary to calculate the load you have to supply. To do this, you simply have to calculate the power demand, whether this be for home or business use, during normal operating conditions. The degree of power that the generator is capable of providing will tell you whether it is sufficient to meet the requirements of your home or business: the amount of fuel the tank carries only determines how long the generator will operate between refueling.You should always choose a generator that can provide a little more power than you need, thus reducing the eventuality of overloading.
Another factor you may have to give some thought to is the decibel level of the new petrol generator. Will you be required to run the generator during the night in the home? If so, it is a good idea to select a silent diesel generator as the noise 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 decent sized 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 problem 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 buy a good quality used generator, as this will cost far less.
Ensuring that you have a diesel generator at hand for emergency situations, such as natural disasters or power outages, or perhaps those times when there is no existing mains electricity (camping is one such example) is a great idea. However, it pays to do your homework and carefully choose a generator that best suits your individual requirements.
