Complete Guide to Buying a Generator and Powering Your Home

Generators provide an essential service during a power outage or natural disaster. They can also be used to power certain appliances in your home on a daily basis. If you are considering purchasing a generator, there are several things you need to know in order to make the best decision for your needs. In this guide, we will discuss the different types of generators available, as well as the factors you need to consider when purchasing one. We will also provide tips on how to care for and maintain your generator.

What are the different types of generators?

There are several different types of generators available on the market, each with its own set of benefits and drawbacks. The most common type of generator is a portable gas generator. These generators are typically small and lightweight, making them easy to transport. They are also relatively affordable and can be used to power a variety of small appliances. However, portable gas generators can be noisy and produce harmful emissions.

Another type of generator is a standby generator which is bigger and more expensive than portable generators. But they offer many advantages. First, standby generators are permanently installed and connected to your home’s electrical system. This means they will automatically turn on in the event of a power outage. They are also much quieter than portable generators and produce fewer emissions. 

It's worth noting the most popular generators used in Ireland would be Petrol and Diesel operated units. The Petrol usually will only generate to a maximum of 7-8KVA and if your power requirements are larger than that then a Diesel Silenced unit is usually the only way to go.

What size generator to power a house in Ireland?

You can run the most critical household equipment, including things such as a refrigerator, freezer, well pump, and lighting circuit with a generator rated at 5,000 to 7,500 watts. A 7500 running watt generator can run all these appliances at once and would be enough to power a house in Ireland. It's also worth noting this will depend on a lot of factors at the same time, including the size of the good pump; some can be high wattage for deeper wells. It will run standard gas heating and oil heating, however, if there are additional heating pumps installed the wattage of these needs to be calculated too

What factors should I consider when purchasing a generator?

There are several factors you need to consider when purchasing a generator. First, you need to decide what type of generator is best for your needs. Portable generators are typically less expensive and can be used to power a variety of small appliances. However, they are not as powerful as standby generators and can be noisy. Standby generators are more expensive, but they offer several advantages, including being permanently installed and automatically turning on in the event of a power outage.

You also need to consider the size of the generator you need. The size of the generator you need will depend on the number of appliances you want to power and the amount of power they require. Be sure to select a generator that is large enough to handle the electrical needs of your home. What needs to be thought about and considered is, if your generator has an output of 6KW, that means 6000 watts. 

You would need to add the Wattage of everything you need to run, to know how much power you actually need.

Also, bear in mind that not everything will be used at the same time. Ie, the cooker will be used short term, the heating won't be used long term. There is an element of trading some units' power for others. 

Some people are happy to run the Fridge, TV, and a few lights. In this instance, a 3.5kw generator would suffice

Here are some tips to help you find the right generator:

• Understand Your Power Needs: The first step is to calculate the wattage of the appliances and devices you want to run during a power outage.
• Choose the Right Fuel Type: Portable generators typically run on petrol while standby generators can run on diesel.
• Consider Run Time: When selecting a generator, be sure to consider the amount of time you need it to run. Some generators can run for hours, while others have a limited run time .
• Maintenance Requirements: Be sure to read the manufacturer’s instructions for the maintenance and care of your generator. Most generators require regular oil changes and must be stored in a dry, ventilated area.

Features That Make a Difference
 

• When choosing a generator, there are several features that can make a difference in the quality and convenience of use. Here are a few to consider:
• Electric start: An electric start button makes it easy to start your generator, even if you're not familiar with how to operate one. This is a convenient feature, especially if you need to use your generator in an emergency situation.
• Remote start: A remote start button allows you to start your generator from a distance, which can be helpful if the unit is stored in a difficult-to-reach location.
• Portability: If you need to move your generator around frequently, look for one with wheels and a handle. This will make it easier to transport, especially if the unit is heavy.
• Runtime: The runtime of a generator is the amount of time it can run before needing to be refuelled. If you'll be using your generator for long periods of time, look for one with a longer runtime.
• Fuel type: Generators typically run on either petrol or diesel. Be sure to choose the fuel type that is most convenient for you.
• Engine: OHV (Overhead Valve) engines provide longer life, longer run times, greater fuel efficiency and quieter running.
• Muffler: Helps reduce engine noise.
• Wheels: Look for pneumatic wheels for easier transportation over rugged terrain like construction sites.

How to calculate what size of a generator is best for my needs?

The size of the generator you need will depend on the number of appliances you want to power and the amount of power they require. Be sure to select a generator that is large enough to handle the electrical needs of your home. To calculate the wattage of the appliances and devices you want to run during a power outage, use this formula: (watts required x hours of use) / 1000 = generator size in kilowatts (kW). For example, if you want to run a fridge and a TV for six hours, you would need a generator that is at least ((700 watts x six hours) + (120 watts x six hours)) / 1000, or about four kW.

Caring for and maintaining my generator

Here are some tips to help you care for and maintain your generator:

• Read the manufacturer’s instructions for maintenance and care of your generator. Most generators require regular oil changes and must be stored in a dry, ventilated area.
• Be sure to use the correct fuel type for your generator. Portable generators typically run on petrol while standby generators can run on diesel.
• Run your generator for a few hours each month to keep it in good working order.
• Be sure to keep your generator clean and free of debris.
• Follow the manufacturer’s instructions for the safe operation of your generator.

If you have any questions about caring for or maintaining your generator, be sure to contact a professional.
