What is a Generator?

A generator is a piece of equipment that converts chemical energy into electrical energy. Their purpose is to generate electricity when grid power can't be accessed. There are many types of generators; some used as a backup supply in case there is a power outage, and others are used in places where the grid power doesn't reach. 

Generators come in all different variations, including:

  • Diesel Generators
  • Petrol Generators
  • Natural Gas Generators
  • Propane Generators
  • Bi-Fuel Generators

How does a Generator work?

A generator converts mechanical or chemical energy into electric energy by forcing the movement and motion of electric charges through the circuit. Older models of generators work by using the large volume of energy that has been powered by turbines. The modernised generators use fuel to work, such as diesel and gas.

There are many parts of an electrical generator, such as the engine, battery charger, fuel system, alternator, voltage regulator, cooling and exhaust systems, lubrication system, control panel and the main assembly. 

What types of Generators are there?

There are three main types of generators, which, although different, also share similarities. The type of generator you need will depend on the reasons for use. Here is more information about the generators:

Inverter Generators

Inverter generators produce AC power, which reverses the direction of the electrical current. The AC power is produced by converting AC power into DC power, by the rectifier, which then reverses it back into AC. This process implements a steady current for all appliances, such as refrigerators and vehicles, to run better. Inverter generators are lightweight, making the installation process easy, and are also compact for straightforward moving abilities.

Standby Generators

Standby generators have the ability to switch on automatically whenever the power fails, like a backup system. When the power comes back on, the standby generator will automatically switch itself, via signals from the electrical supply. These generators are usually used in large places holding a lot of people, such as hospitals, hotels, apartment blocks and restaurants and also for safety systems that must always be able to work.

Portable Generators

Portable generators come in handy for many different reasons and are suitable for a number of uses. For incidents such as natural disasters or other catastrophes, causing the grid power to break down, portable generators can still provide a power supply. These generators are suitable for purposes such as residential and smaller business properties such as shops and construction sites as a power supply for small equipment and tools.
