With the many choices of standby generators on the market, it is tough to know which one to purchase. That’s why we decided to prepare this comprehensive guide so your home never runs out of power.

1. What is A Generator?

Generators are the backup solution to power your home and business owners. They can be used when the primary source of the power line is down.

In the event of an unexpected power outage, standby generators can last for around 3000 hours, which means 100 hours annually. They operate automatically and can be used as a standalone unit or as your property’s electrical system.

What we love the most about standby generators is their ability to run constantly during power disruptions without much effort. You can buy a generator for the house depending on the amount of supply you need.

2. Should I Buy A Generator for My Home in the UK?

Imagine cooking some dish at your home during the night and a sudden power outage happens, what will you do when no other light source is there?

Unfortunately, you will have to stop cooking. But this situation can still be handled. The worst comes when stormy weather hits your region and the power goes off for several days. Nothing is better than a standby generator in that case.

If there is urgent work to do or you are staying with a family member with an illness, electricity is necessary. Not only that but living in an area with frequent power outages and prolonged power supply disruptions increases the need for generators.

3. Types of Generators for House

When it comes to your home, there are different types of generators to choose and you must know about common ones from them.

Portable Generators

Portable generators for hours are operated using propane, gasoline, and solar batteries as they are easily available. As their size is small, you can carry it anywhere you go. However, it’s best to use them while going camping or in an emergency situation during a power outage.

Although portable generators can be a great choice but not enough to power up your entire home, they can supply power from 1-15 KW which is sufficient enough to run basic electrical tools.

So, you can use them for meeting the construction need of your home. Some prefer petrol generators while many still use diesel generators but none of them are good for the environment.

Inverter Generators

They are known for providing electricity in three phases while maintaining a high-frequency inversion process from AC to DC and back to a constant AC output.

Standby Generators

Standby generators are of permanent type or you can say semi-permanent. And yes, it’s going to take up a lot of space even more than a standard AC. Such type of generators is packed with great fuel efficiency so that it can empower the entire problem with no issues in unexpected situations. You also need to provide proper maintenance from time to time to keep them last for around 30 years.

4. How to Choose Standby Generator for Home Use?

Before buying any standby generator, you have to take into account various factors:

Power Consumption of Various Equipment in your Home:

The very first factor is the Power Consumption of your equipment. Buying a generator after knowing how much power you need it to generate is a smart move. Here, we have listed all major home equipment that one may need and their power consumption requirements.

  • Toaster: 1050 – 1500 W
  • Vacuum Cleaner: 1000 – 3000 W + Starting watts (multiply individual watts by 3)
  • 2 HP Motor : 6000W (starting watts) and 2000W (operational watts)\
  • 1 HP Moto : 3000W (starting watts) and 1000W (operational watts)
  • Water Heater: 3000W
  • Iron: 1000W
  • Fridge: 700 – 1000W (starting watts)

Now that you know the basic necessary consumption requirements of electrical appliances. All you need is to add up the consumption watts of each appliance that you need to run altogether. Once you get that value, say if 6000W of consumption is required by electrical appliances running at the same time, then you should only consider buying a 6 KW generator or higher.


What amount of load are you expecting the generator to carry? It just depends on the requirements of your home or factory. In case you end up putting extra load then the electrical appliances may get damaged. Thus, your generator needs to have a high capacity depending on the amount of load you want to put.

Fuel Type

This is pretty important to consider because our environment is already going through a lot of changes. Go with an environment-friendly fuel like solar energy. Solar energy not just eliminates your fuel cost but also is eco-friendly and therefore, a solar generator will be worth having.
