How Big of a Generator Do I Need for My Home?

Determining the right size generator for your home is crucial for ensuring reliable power during outages. Here’s a guide using a 2,000 SF home as an example, brought to you by Shockwave Generators & Electric, serving Houma, Morgan City, Thibodaux, Raceland, Lockport, and surrounding areas.

Understanding Generator Sizes

Whole home generators come in various sizes, typically measured in kilowatts (kW). For a 2,000 SF home, the average requirement ranges from 20kW to 24kW, depending on your power needs.

Key Appliances and Power Consumption

Certain appliances consume more power and should be prioritized when sizing your generator:

  • HVAC System: 3-5 kW
  • Refrigerator/Freezer: 1-2 kW
  • Electric Water Heater: 4-5 kW
  • Oven/Range: 5-6 kW
  • Lights and Outlets: 2-4 kW

Calculating Your Power Needs

To calculate your total power needs:

  1. List Essential Appliances: Identify critical appliances and their power requirements.
  2. Sum Power Consumption: Add the power requirements of all essential appliances.
  3. Factor in Surge Watts: Account for the initial surge when appliances start up, usually 1.5-2 times the running watts.

For a 2,000 SF home, a generator in the 20-24 kW range is typically sufficient to cover essential appliances and some additional circuits.

Transfer Switches

A transfer switch is essential for safely connecting a generator to your home’s electrical system. It ensures seamless transition of power during an outage and prevents backfeeding, which can be hazardous.
