How To Calculate The Right Generator Size For Your Home

Choosing the right generator for your home can be a daunting task. With various factors to consider, from power requirements to fuel types, making an informed decision is crucial. Working with an industry expert, like Canter Power, is the easiest way to navigate the details and ensure that you have chosen the ideal generator model for your home.  If you’re interested in learning how to properly calculate the right generator size for your home, you will find this guide to be resourceful.

What Size Generator Do You Need?

Ensuring you have a reliable power supply during an outage starts with understanding your power needs. This involves identifying which appliances are essential and calculating their wattage requirements. By accurately determining your power needs, you can select a generator that provides sufficient power to keep your home running smoothly during an emergency.

List Your Essential Appliances
The first step in determining the right generator size is to list the essential appliances you need to power during an outage. These typically include:

• Refrigerator and freezer
• Heating and cooling systems
• Lights
• Water heater
• Sump pump
• Medical equipment
• Cooking appliances (microwave, stove)

Calculate the Size of the Generator
Once you have your list, calculate the wattage requirement for each appliance. You can usually find this information on the appliance label or user manual. Add up the wattages to get a total wattage requirement. This total will help you determine the standby generator sizing you need to keep your home running smoothly during a power outage.

Types of Generators

Portable vs. Standby Generators
When choosing a generator, it’s important to understand the differences between the two main types: portable and standby generators. Each type offers distinct advantages and is suited for different power needs and situations. Let’s explore these options to help you make an informed decision.

• Portable Generators: These are movable and can be used for a variety of purposes, from powering a few essential appliances to providing electricity for outdoor events. They are typically less expensive but require manual setup and refueling.
• Standby Generators: These are permanently installed outside your home and automatically kick on when there is a power outage. They are more expensive but offer convenience and higher power capacity, making them ideal for long-term outages.

Fuel Types
Portable generators can run on various fuel types, including gasoline, propane, natural gas, and diesel. Depending on the generator model, Generac standby generators may run on liquid propane vapor (LP), Pipeline Natural Gas (NG), or Diesel fuel.

Calculating Generator Size

Accurately calculating the size of the generator you need is essential to ensure it can handle the power demands of your home. This involves understanding the differences between starting and running watts, as well as using tools like sizing calculators to simplify the process. By accounting for these factors, you can confidently select a generator that meets your needs and provides reliable power during outages.

Determining Starting vs. Running Watts
When sizing a generator for a house, it’s important to understand the difference between starting watts and running watts:

• Starting Watts: The initial surge of power needed to start an appliance
• Running Watts: The continuous power required to keep the appliance running

Using a Generator Sizing Calculator
A sizing calculator can simplify the process. A helpful tool such as the Generac load calculator can help you input your appliances and their wattage requirements to get an accurate estimate of the generator size you need. This can be particularly useful for those unfamiliar with electrical calculations.

Additional Considerations

Noise Levels
Some generators can be noisy, which may create a disturbance, especially in residential areas. Check the decibel ratings of potential generators to ensure you choose one with acceptable noise levels. With an operational level below 60 dB, the Generac Guardian series of generators offers some of the quietest models available on the market.

Energy Efficiency
Energy efficiency is another crucial factor. Efficient generators consume less fuel, reducing operational costs and environmental impact. Talk to your Canter Power Customer Experience Coordinator about energy-saving features and and models which offer high efficiency ratings.

Local Regulations and Safety
Before purchasing a generator, familiarize yourself with local regulations and safety guidelines. Some areas have specific requirements for generator installation, including permits and noise restrictions. Always follow manufacturer guidelines for safe operation and maintenance to prevent hazards such as carbon monoxide poisoning.

Selecting the right generator size for your home is essential to ensure you have reliable power during outages. By understanding your power needs, knowing the types of generators available and using tools such as sizing calculators, you can make an informed decision. Consider additional factors, for example, noise levels, energy efficiency, and local regulations to find the best generator for your situation. With the right generator, you can keep your home running smoothly, no matter the circumstances.

Remember, calculating the size of a generator involves more than just adding up wattages. It requires careful consideration of starting and running watts, efficiency, and safety regulations. Utilize resources like the sizing calculator to simplify the process and ensure you select the best generator for your home.
