Are you wondering how much generator power you need for your home? There’s nothing worse than losing power when you need it the most. If you’ve ever gone without power for an extended period, you know what we mean. Not only does it throw off your schedule, but it can be inconvenient and unorganized. One way to prevent this is by investing in a home generator. Home generators are easy to install, and you can keep them behind the scenes, only to use them when you need them. But what if you don’t know how much power to add? We’re here to help. Here’s our complete guide on home generator sizing.

Understand Your Power Needs

Before you start shopping for a generator, it’s crucial to understand your power needs. What appliances and devices do you want to keep running during an outage? Make a list of essential items like lights, refrigerators, heating or cooling systems, and important electronics. Understanding your power needs will help you determine the generator size required to meet your requirements.

Calculate Starting and Running Watts

There are many different generator sizes, and their capacity is measured in watts. Two essential factors to consider when calculating your generator size are starting watts and running watts. Starting watts are the extra power needed to kickstart appliances with motors, like refrigerators and air conditioners. Running watts, on the other hand, represent the continuous power required to keep those appliances running.

To calculate your starting and running watts, check the labels on your appliances or refer to their manuals. Sum up the starting watts of all appliances you want to power simultaneously, and then do the same for the running watts. This will give you a clear idea of the generator size you’ll need.

Choose the Right Generator Type

Now that you’ve determined your power needs, it’s time to choose the right type of generator. There are two main types of generators: portable generators and standby generators.

Portable Generators

These generators are versatile and come in various sizes. They are an excellent choice for providing temporary power during outages. Portable generators are usually less expensive and can be moved around your property as needed. However, they need manual startup and may not provide power automatically when the grid goes down.

Standby Generators

Standby generators are permanent fixtures installed outside your home. They are connected directly to your electrical system and can automatically provide power during an outage. Standby generators are capable of handling larger power loads and are the preferred choice for those seeking a seamless backup power solution. They come in various sizes to meet different power needs.

Generator Size Matters

The generator size you choose should match or exceed your calculated starting and running watts. For example, if your total starting watts add up to 5,000 and your running watts total 3,000, you should opt for a generator with a capacity of around 5,500 watts or higher. It’s better to have a larger generator than one that’s too small, as an undersized generator may overload and cause damage to your appliances.

Fuel Source Options

Next, you need to decide on the fuel source for your generator. There are three main options to choose from.

Gasoline Generators

These are common and readily available, but they can be noisy and require regular refueling. They’re typically used for smaller power needs.

Propane Generators

Propane generators are more fuel-efficient and produce cleaner emissions than gasoline. They are suitable for medium-sized power requirements and have a longer shelf life.

Diesel Generators

Diesel generators are known for their durability and reliability. They are ideal for larger power needs and are often used in industrial settings.

Noise Levels and Location

Generators can be noisy, which is something to keep in mind, especially if you live in a residential area. The noise level of a generator is measured in decibels (dB). Smaller portable generators tend to be louder, while larger standby generators are quieter. The location of your generator is also crucial. You’ll want to place it in an area where the noise won’t disturb you or your neighbors. A professional installation service can help determine the best location and even install sound barriers to reduce noise.

Budget and Warranty

Your budget is another critical factor when choosing a generator. Generators can vary greatly in price, so it’s essential to find one that fits your financial capabilities. Keep in mind that a generator is an investment in your home’s safety and comfort during outages, so don’t compromise quality for a lower price. Additionally, consider the warranty that comes with your generator. Warranties can range from a few years to a lifetime, and a longer warranty often reflects the manufacturer’s confidence in their product. Investing in a generator with a solid warranty can save you money on repairs in the long run. If you’re on a tight budget, don’t forget to explore financing options or look for discounts on generators. Some install service providers may offer financing plans to make your generator purchase more manageable.

Installation and Maintenance

Once you’ve selected the right generator for your needs, it’s time to think about installation and maintenance. Proper installation is crucial for the generator to function efficiently and safely. This is where an install service comes in handy. They have the expertise and experience to set up your generator correctly. Regular maintenance is also essential to ensure your generator runs when you need it most. This includes oil changes, filter replacements, and periodic testing.
