Understanding Your Power Needs

Before diving into specific calculations, it is important to understand your home’s power needs. Consider the essential appliances and devices you want to keep running during a power outage. 

This could include:

  • Refrigerator: This is vital for food preservation, especially in warmer climates.
  • Freezer: Similar to the refrigerator, the freezer helps prevent food spoilage.
  • Heating and cooling systems: Maintaining comfortable temperatures is crucial, particularly during extreme weather conditions.
  • Lighting: Having basic lighting during an outage ensures safety and provides a sense of normalcy.
  • Medical equipment: If you rely on any life-sustaining medical devices, ensure the generator can support their power needs.

Once you have identified your essential appliances, it is time to determine their wattage requirements. This information can usually be found on the appliance label or owner’s manual.

How to Correctly Size Your Generator

To understand the correct generator size your home needs, start by adding the wattages of all the essential appliances you want to run simultaneously. This will give you your total running wattage.

Some appliances, like refrigerators and air conditioners, require a temporary burst of power to start up. This is called surge wattage and can be 2-3 times higher than the running wattage. To account for this, multiply the starting wattage of your largest appliance by 1.25 and add it to your total running wattage.

Just to be safe, it is wise to factor in a 20 percent margin to accommodate future needs or unexpected power demands. This ensures your generator can handle unforeseen situations without overloading.
