More-and-more firms within the UK are beginning to browse for diesel generators for sale; this is not necessarily a reflection on the capabilities of the National Grid, but more an appreciation of the need to be able to resist the effects of power failures. Electricity is the lifeforce of modern operations, and without it, many companies would struggle to be able to fulfil their various duties. Understandably, many of these new investors do not have a comprehensive understanding of how these generators operate, or what they consist of. It is for this reason that the team here at Generators Online are more than happy to provide you with a beginners guide.

Control Panel

In times gone by, control panels adorning generators were incredibly simple – often consisting of a couple of switches, this was a feature which solely controlled the switching on-and-off of the generator. However, thanks to the advancements in available technology, this has undergone a sizable redesign. Now, you can expect a control panel to be able to, for example, monitor the power output, as well as check on the temperature of the diesel engine. This not only helps users to optimise the way in which their unit is operating; it also allows for a far-more rigorous check of the various internal mechanisms.


If you were to take a survey, using generator owners as the participants, and asked what they thought is the most important element within a generator, the likelihood is that they would respond with the engine. This answer is not only to be expected, but also not totally wrong. The engine, hooked up to the fuel tank, ensures that all moving mechanisms have the energy necessary to conduct their assigned functions. Within any power application, the necessity of the engine cannot be underestimated.


For those of you that are not familiar with the way in which a generator actually creates a viable power supply, allow us to offer you some insight into the matter. The alternator’s primary function is to use the accelerated rotation of the shaft to create electricity. With a series of magnets rigged to create a field that can subsequently forge an electrical field through the machine, the alternator effectively is the conductor which transfers the electrons across a series of wires. There are some that consider this to be the most integral piece of a diesel or electric generator.

Exhaust System

As is to be expected, a combustion engine produces a number of harmful toxic gasses – most notably is carbon monoxide which, if directly inhaled by humans, can be deadly. It is for this reason that modern diesel power generators are fitted with a simple-yet-effective exhaust system. In essence, these are a series of pipes which ventilate the gases away from people, and into the atmosphere where they can do no harm. Should you have your generator set-up inside a building, the need for an adequate exhaust is even more important.
