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 seem quite confusing to those without the necessary knowledge. What source of fuel do you prefer - diesel or petrol? Do you need a small "emergency" generator for the home, or do you need one with plenty of power to act as a back up when the mains electricity fails in your business? If you don't have sufficient understanding of how generators work, you will find it difficult to choose.
How then, do you make a choice? To begin with, you should investigate for what precise purpose you will need the generator, as this will help you to determine the capacity. If you need a generator for around the home, it would not make sense to choose a heavy duty industrial generator, as it would provide 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 most often found in agricultural environments, on construction sites and in factories and warehouses: in reality, just about any place there is a requirement 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 is unreliable (agricultural areas and factories).
When you are deciding upon your generator needs, you need to choose the most efficient model. The size of the new petrol generator is determined by the output and speed provided by the manufacturer: generally speaking, 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 are suitable for home use, whereas the higher ones are more than ample for most industrial applications.
The efficiency of the model is the initial step: however, you will also have to calculate the load you need to supply. To do this, you just 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 tell you whether it is adequate enough 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.It is always wise to choose a generator that provides a little more power than you require, thus minimising the chances of overloading.
Another factor you will have to think about 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 output of these is considerably less than traditional diesel generators. It is also a good idea to opt for 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 noise output is not such an important factor if it is used in an industrial situation, or during the day.
For generators that will be used infrequently, it makes sense to purchase a good quality used generator, as this will save you a good deal of money.
Ensuring that you have a generator at hand for emergency situations, such as natural disasters or power outages, or perhaps those times when there is no electricity supply available (camping is one such example) is a great idea. However, you should do your homework and carefully choose a generator that best suits your individual needs. |
