A Homeowner’s Guide: What Size Generator Do You Need to Cover Your Home?

When the power goes out, it's important to be prepared. A generator can be a lifesaver in those situations, but you need to make sure you have the right size generator for your needs.

In this blog post, we will discuss what size generator you need to cover your home. We will also talk about some of the factors you need to consider when choosing a generator.

What is a generator?

A generator is a device that produces electrical energy from mechanical sources such as an internal combustion engine or solar panels. Generators are used to provide backup power for homes and businesses in case of a power outage, to supply power to remote or off-grid locations, and for other applications requiring electrical energy.

Generators can be powered by a variety of fuel sources, including gasoline, diesel, natural gas and propane. Generators produce electricity by combining the mechanical energy from their power source with an alternator or electrical generator. The alternator converts this mechanical energy into alternating current (AC) electricity that can be used to power tools and appliances.

Generators come in a range of sizes, from small portable units up to large industrial-sized models. Some generators are used to provide backup power for homes in case of a power outage, while others are used to generate electricity for businesses and other applications requiring electrical energy. Generators can also be used in recreational activities such as camping and RVing.

Factors to Consider When Choosing a Generator

Type of Fuel

The type of fuel you choose for your generator will depend on your needs and budget. Gasoline generators are generally more affordable, but they require regular refueling and maintenance. Diesel generators are typically more expensive but can provide longer run times. Natural gas and propane generators are also available, though they may not be suitable for all applications.

Generator Capacity (Wattage)

The wattage rating of the generator will determine how much power it can produce. A higher wattage rating means that the generator is capable of producing more electricity, but it also means that more fuel is needed to operate it.

When choosing a generator, make sure you select one with enough capacity (wattage) to power all the tools and appliances you will need during a power outage.


Portable generators are great for homeowners who need to move their generators from place to place or for those who do not require a large amount of electricity. Portable generators are typically lighter in weight and can be easily transported, though they may not be suitable for large-scale applications.

Noise Level

Generators can produce a significant amount of noise, so it's important to consider the noise level of the generator you buy. Some generators are designed to be quiet, while others may be too loud for some applications. Make sure you check the decibel (dB) rating of the generator before you buy.


The price of a generator will vary depending on its size, type, and features. Make sure to check reviews and compare prices before buying a generator to ensure you are getting the best value for your money.

What size generator to run a house

The wattage rating of your generator will determine how much power it can provide. Generally, a 5,000 to the 10,000-watt generator is sufficient to handle the average home’s electrical needs during a power outage. However, this can vary depending on the type and number of appliances you need to power.

Safety Tips for Operating a Generator

1. Always keep your generator in a well-ventilated area outside, away from open windows or doors.

2. Never operate your generator inside any enclosed space, including your garage.

3. Make sure your generator is properly grounded and connected to an approved transfer switch or outlet.

4. Ensure that all fuel lines and connections are firmly secured and free from leaks before operating the generator.

5. Always keep a fire extinguisher close by in case of emergency.

6. When refueling, ensure the generator is turned off and cool before adding fuel.

7. Keep all cords and cables away from high-traffic areas to avoid tripping hazards.


Generators are a great way to provide backup power for homes and businesses in case of a power outage. When choosing a generator, it is important to consider the type of fuel it uses, its wattage rating and portability, how loud it is, and how much you are willing to spend. A properly sized generator can ensure that you have the power you need when you need it.

Making a decision on which generator to purchase can be intimidating, but by considering your needs and researching the different options available, you can find the best generator for your circumstances. With so many options available, there is sure to be a generator that fits your needs perfectly.
