Power outages are inevitable, especially during natural disasters or extreme weather conditions. Having a home generator can keep your family safe, comfortable, and provide peace of mind. However, choosing the right size generator for your home can be overwhelming. In this article, we will guide you on how to size a home generator in 2023.
Step 1: Calculate Your Wattage Needs
The first step in sizing a home generator is to calculate your wattage needs. This is the amount of power that your home appliances and electronics will require during an outage. Make a list of all the essential items that you want to power, such as lights, refrigerator, heating and cooling systems, and medical equipment.
Next, determine the running wattage and starting wattage of each item on your list. Running wattage is the amount of power needed to keep an appliance running, while starting wattage is the amount of power needed to start the appliance. Add up the running and starting wattage of all your items to get your total wattage needs.
Example:
Refrigerator (running wattage): 700W
Refrigerator (starting wattage): 2200W
Lights (running wattage): 60W
Heating system (running wattage): 5000W
Total wattage needs: 7960W
Step 2: Choose the Generator Size
Once you have calculated your wattage needs, you can choose the generator size that can handle your power requirements. Generators are available in different sizes, ranging from 1000W to 10,000W or more. A generator's size is determined by its output capacity, which is measured in watts.
It's essential to choose a generator that can handle your wattage needs without overloading or underloading. Overloading can damage your generator and appliances, while underloading can lead to inefficiency and higher fuel consumption.
Example:
If your total wattage needs are 7960W, a generator size of 8000W or higher would be suitable. This would provide enough power to run all your essential items without overloading or underloading the generator.
Step 3: Consider Fuel Type and Runtime
When choosing a home generator, you should also consider the fuel type and runtime. Home generators are available in three fuel types: gasoline, propane, and diesel. Each fuel type has its advantages and disadvantages, such as cost, availability, and shelf life.
The runtime of a generator refers to how long it can provide power on a single tank of fuel. Generators with larger fuel tanks can run for longer periods without refueling, while smaller tanks may require more frequent refueling.
Example:
If you live in an area with frequent power outages, a generator with a larger fuel tank and longer runtime would be suitable. A propane generator may be a better option if you have a propane tank on your property, while a gasoline generator may be more convenient if you have easy access to gasoline.
Overall, sizing a home generator requires careful consideration of your wattage needs, generator size, fuel type, and runtime. Choosing the right generator can provide reliable backup power during outages and protect your home and family.
