What Is a Generator Used For?

A generator is an extremely useful appliance that will supply electrical power if and when you may experience a power outage. In certain critical businesses these are used as a standby power supply should the main grid experience an outage.

They ensure that during any power outage, that the generator will allow the business daily activities and business operations to keep going. That is because they can then supply the power required to help keep the business up and running.

These are becoming very popular in homes throughout the UK, and especially those that are prone to having regular outages. They are also popular in more remote areas and in areas where bad weather can put the power down for days at a time.

In the most simple of terms, a generator is therefore a machine that can generate electricity from a different type of power source. For example you can use a gas powered generator to create electricity to run a number of appliances.

Top 5 Standby Generators for Home Use

Böhmer-AG 6500W Petrol Generator 2.8Kw

88% customer satisfaction based on 200+ online buyer reviews

This is the best, reasonably priced model we could find. I have this model myself and I cant recommend it highly enough, especially at this price

It is driven by a powerful 4 stroke, 210cc, 8 horsepower engine that's actually pretty quiet when it is running and you could easily use it in the house if you rigged up a bit of an exhaust. Its about the sound level of two people talking to each other ( 66Db )

You get two 240V 3 pin UK plug outputs and a 12V DC output to suit a variety of power supply needs. You could have your heating on, your lights and your TV no problem and even make your dinner

This unit will run for around 10 hours on a single tank of fuel and put out a constant 2600w. Its definitely well worth the money.

You could easily run several appliances with this generator in an emergency or even for sustained periods.

This unit will run for around 6 hours on a single tank of fuel and will put out a constant 1700w. So as far as I am concerned, compared to the model above, it's not as good in peformance or value. 

It is a bit neater looking and very slightly quieter but the 6500 model would be my choice.

Who Would Buy An Electric Generator?

There are quite a number of people who are willing to invest in buying some type of generator. Below we have listed the most popular uses for a generator:

  • Used as back up power for your house
  • Used as standby power for a business
  • Used in RVs, Caravans and for Camping
  • Used to provide temporary power on a building or construction site
  • Used to provide power on farms
  • Used to provide power at pop concerts, events, markets and exhibitions
  • Used for outdoor catering facilities
  • Used in Sport’s stadium

This is not an exhaustive list but hopefully it demonstrates the general and widespread uses of owning a generator, and just how useful a machine they can be.

What Types of Generators Exist?

There are three different types of generators:

  1. Standby Generator
  2. Portable Generator
  3. Inverter Generator

Let’s have a closer look at each of those so as you can clearly understand the difference.

What Is a Standby Generator?

A standby generator, as the name would suggest, is a generator that comes on when the main power from the grid fails. This grid failure is referred to as an outage. These are prone to happen in remote areas, areas affected by bad weather and in some cities where the main power grids are simply over loaded.

Critical building such as hospitals, telephone exchanges and emergency services will have highly complex standby generators. Many of those will also have a standby battery system in case the generator fails. The reasons for this are obvious in that there is usually a risk to life.

Some homeowners will also invest in a high quality standby generator. This is especially true if they live in a remote area, or in an area prone to long and regular power outages.

There are a few different ways of installing this type of standby generator and I have created a separate buying guide on that.

What Is a Portable Generator?

This is by quite a distance the most popular choice for homeowners and for small businesses. Again as the name would suggest, these are smaller machines, usually with wheels that can be moved around to supply electricity.

You will see these at fairs, events, outside catering venues and on construction sites. Many homeowners also use these to provide some form of electricity supply, should their power supply fail.
