There are many options for the homeowner and business operator when the time comes to choose a generator: so many, in fact, 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 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 generators work, you will find it difficult to select one.
How then, do you make a choice? As a first step, you should decide for what precise role you will need the generator, as this is a good method of determining the capacity.
If you require a generator to use in the home environment, it would not make sense to choose a heavy duty industrial generator, as it would provide much more power than you need.
Similarly, if you need to run machinery, a small generator will not be powerful enough as it is likely 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, anywhere there is a need for a portable and reliable source of energy.
This can be because there is no mains power (for example construction sites) or the power supply cannot always be relied upon (agricultural areas and factories).
When you are working out your generator requirements, you need to opt for the most efficient model. The size of the silent generator is indicated by the output and speed provided 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 can be used in the home, whereas the more powerful ones provide more than enough power for most industrial applications.
The model’s efficiency is the initial step: however, it is also necessary 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 is able to provide will tell you whether it is adequate enough to meet the needs of your home or business: the capacity of the fuel tank only determines how long the generator will operate between refueling.It is always sensible to choose a generator that provides a little more power than you require, thus reducing the possibility of overloading.
Generators Noise level
Another factor you may have to consider is the noise level of the portable generators. Does the generator need to be run during the night in the home? If this is the case, it is a good idea to choose a silent diesel generator as the noise level of these is much lower than traditional diesel generators.
It is also sensible to choose a silent diesel generator with a decent sized fuel tank, to ensure that it runs overnight, thereby avoiding refueling in the middle of the night. The decibel output is not such a 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 purchase a good quality used generator, as this will save you a significant amount of money.
Having a generator available 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 good idea.
