What Size Generator Do I Need? Ultimate Sizing Guide

Choosing the right size generator is crucial for ensuring your home or business stays powered during outages or for specific needs. But how do you know which size is right for you? This comprehensive guide will help you navigate the process of selecting the best generator size. We will explore different types of generators and teach you how to calculate the power you need.

Understanding Generator Sizes

What Size Generator Do I Need

Generators come in various sizes, measured in watts. The wattage indicates how much power the generator can supply. Here’s a quick overview of different types of generators and their typical uses:

Type of GeneratorTypical WattageUses
Portable Generator1,000 - 10,000 wattsCamping, small appliances
Inverter Generator1,000 - 5,000 wattsElectronics, RVs
Standby Generator7,000 - 20,000 wattsWhole house, business

Each type of generator is suited for different tasks. Portable generators are ideal for small-scale use, while standby generators can power an entire house or business.

How to Calculate Your Power Needs

To choose the right generator, you need to know your power requirements. Here are the steps to calculate the power you need:

  • List Your Essential Appliances

List all the appliances you want to power during an outage or for your use. This might include your refrigerator, lights, air conditioner, and other essential devices.

  • Find The Wattage Of Each Appliance

Check the labels on your appliances to find their wattage. This information is usually listed on the back or bottom of the appliance. Write down the wattage for each item.

  • Add Up The Wattage

Add the wattage of all your appliances to get a total. This total represents the minimum power your generator needs to provide.

  • Consider Starting Watts

Some appliances require extra power to start, known as starting watts. Ensure your generator can handle these additional watts. For example, a refrigerator might need 2,000 watts to start but only 500 watts to run continuously.

  • Choose A Generator With A Little Extra Power

Choosing a generator with slightly more power than your total requirement is wise. This extra power ensures you have a buffer for any additional needs.

Examples of Common Power Needs

Here are some typical power requirements to help you understand how much power you might need:

  • Basic Home Needs: 3,000 to 5,000 watts
  • Home with Air Conditioning: 5,000 to 7,500 watts
  • Small Business: 7,500 to 10,000 watts
  • Whole House: 10,000 to 20,000 watts

Portable Generators

Portable generators are small and mobile, perfect for camping or small tasks. They typically provide up to 10,000 watts of power.

Inverter Generators

Inverter generators are known for being quiet and efficient, making them ideal for sensitive electronics and RVs. They usually provide up to 5,000 watts of power.

Standby Generators

Standby generators are large and powerful, capable of powering an entire house or business. They typically provide up to 20,000 watts of power.

Tips for Choosing the Right Generator

Here are some helpful tips for selecting the right generator:

  • Think About Your Needs: Ensure the generator can power all your essential appliances.
  • Consider the Size: Choose a generator that fits your space and meets your power requirements.
  • Check the Fuel Type: Different generators use various fuels. Make sure you have easy access to the fuel type your generator uses.
