How to Choose A Generator That Is Right For Your Needs
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 very confusing to the uninitiated. What type of fuel do you prefer – diesel or petrol? Do you need a small “emergency” portable 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 silent generators work, you will find it difficult to select one.
How then, do you make a choice? To begin with, you should investigate for what exact purpose you will require the generator, as this will help you to determine the capacity. If you need a generator for around the home, it would not be a good idea to choose a heavy duty industrial generator, as it would provide more power than you really need. Similarly, if you need 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 most 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 due to the absence of mains power (as with construction sites) or the mains power cannot always be relied upon (agricultural areas and factories).
In determining your generator requirements, you need to select the most efficient model. The size of the new diesel generators is specified by the output and speed as given by the manufacturer: usually, a more powerful generator has a higher output and speed. The majority of generators range between an output of 5KVA (kilovolt-ampere units) and 2500KVA. The lower KVA generators are suitable for home use, whereas the more powerful ones are more than ample for most industrial applications.
The model’s efficiency rating is the initial step: however, it is also necessary to calculate the load you have to supply. To do this, you just have to figure out the power demand, whether this is for home or business use, during normal operating conditions. The level of power that the generator can output will indicate 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.It is always sensible to choose a generator that provides a little more power than you really need, thus minimising the chances of overloading.
Another factor you may have to think about is the noise output of the portable generator. Will you need to run the generator during the night in the home? If so, you should select a silent diesel generator as the decibel level of these is much 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 ensure that it runs overnight, so you don’t have to be worried about refueling in the wee small hours. The noise output is not such a critical factor if it is used in an industrial situation, or during the day.
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.
Ensuring that you have a generator available 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 do your homework and carefully choose a generator that best suits your individual needs.
