how to size a portable generator for a house ?

Sizing a portable generator for your home can seem daunting, but it doesn’t have to be. By understanding the basics of portable generator power, you can easily determine the right size generator for your power needs.

First, it’s important to understand the differences between watts and volt-amps (VA). Watts measure the actual power used by an appliance or device, while VA measures the amount of power necessary to start an appliance or device. Generally, most appliances will use more VA when starting than when running.

To size a portable generator for your home, start by listing the appliances you plan to power, along with their wattage or VA ratings. Then, add up the wattage or VA ratings for each appliance. This will give you the total wattage or VA you need from your generator.

It’s important to remember to add an additional 25-50% to your total wattage or VA when selecting a generator size. This will ensure you have enough power to start and run all of your appliances without overloading the generator.

Finally, when you’re ready to purchase a generator, look for one with a surge rating that is higher than the total wattage or VA of your appliances. This will ensure the generator can handle the surge of power needed when starting your appliances.

By following these simple steps, you can easily size a portable generator for your home and be sure you have the right amount of power when you need it.
