If you need to choose a generator, whether it is for home or industrial use, there are many possibilities: so many, in fact, that it can be quite confusing to the uninitiated. What type of fuel are you going to use – diesel or petrol? Is your requirement for a small “emergency” generator for the home, or do you need one with an abundance of power to act as a back up when the mains electricity is not reliable in your business? If you don’t have much of an understanding of how generators work, it will be a difficult decision.
