How to Calculate Your Home’s Power Needs and Choose the Perfect Generator

Home Power Needs

When it comes to choosing the perfect generator for your home, understanding your power needs is crucial. In this guide, we will walk you through the process of calculating your home’s power requirements and selecting the ideal generator. With examples and benefits in mind, let’s dive in!

Calculate Your Home’s Power Needs

To start, create a list of the essential appliances and devices in your home that you need to power during an outage. Examples include refrigerators, lights, computers, and air conditioners. Next, find the wattage of each item, typically listed on the device or in the owner’s manual. Add up the wattage to get your total power requirement.

Starting and Running Watts

Keep in mind that some appliances, such as refrigerators and air conditioners, require more power to start than to run. Therefore, consider both starting and running watts when calculating your home power needs. For example, if your refrigerator needs 2000 watts to start and 800 watts to run, ensure the generator can handle the higher starting wattage.

Choosing the Perfect Generator

With your home’s power needs calculated, you can now focus on selecting the right generator. Consider the following factors:

Generator Type

There are two main types of generators: portable and standby. Portable generators are mobile and can be used for various purposes, while standby generators are permanently installed and provide automatic backup power during outages. Assess your specific needs and budget to determine the best option for your home.

Fuel Type

Generators run on different fuel types, such as gasoline, diesel, propane, and natural gas. Each fuel has its advantages and disadvantages. For example, gasoline is widely available but has a shorter shelf life, whereas propane lasts longer and burns cleaner but may be more expensive. Choose the fuel type that best suits your requirements and availability in your area.

Power Output

Ensure the generator you choose can handle your home’s power needs. For example, if your home requires 7500 watts, a 5000-watt generator will not suffice. Consider a generator with a slightly higher output than your calculated needs to avoid overloading and accommodate potential future needs.

Benefits of Choosing the Right Generator

Selecting the perfect generator for your home comes with numerous benefits. Here are a few:

Uninterrupted Power Supply

By choosing the right generator, you can enjoy continuous power during outages, keeping your essential appliances running and your family comfortable.

Cost Savings

A properly-sized generator ensures you’re not wasting fuel or overloading your generator, leading to potential damages. Consequently, you’ll save on repair costs and fuel expenses.

Peace of Mind

Knowing your home is prepared for power outages gives you peace of mind, especially during extreme weather or natural disasters.


In summary, determining your home power needs and selecting the perfect generator is a crucial step towards ensuring uninterrupted power supply and peace of mind. By considering the type, fuel, and power output of generators, you can choose the best option for your needs and enjoy the numerous benefits that come with it. So, take the time to calculate your power requirements and invest in the right generator today!
