Understanding Your Power Needs
Before purchasing a generator, it's crucial to understand your power requirements. Calculate the wattage of essential appliances you wish to power during an outage. These might include refrigerators, sump pumps, furnaces, lighting, and more.
Calculating Total Wattage
List each appliance's starting and running wattage. Keep in mind that starting wattage is usually higher, especially for motor-driven appliances. Once you have your list, add up the total to determine the desired generator capacity. Use the following table as a rough guide:
| Appliance | Running Watts | Starting Watts |
|---|---|---|
| Refrigerator | 700 | 1,200 |
| Sump Pump | 800 | 1,300 |
| Furnace Fan | 750 | 1,500 |
| Lights (10 bulbs) | 600 | 600 |
For home backup scenarios, look for generators in the 5,000W–13,000W range.
Fuel Generators: Powerful and Reliable
Fuel generators, often powered by gasoline or propane, are favored for their powerful output. They are well-suited for home backup situations and extended outages. However, remember that they must be operated outdoors, far from windows and doors, due to carbon monoxide risks.

FAQs
What is a home backup generator and why do I need one?
A home backup generator is a power source that automatically provides electricity to your home during a power outage. It ensures that your essential appliances and systems, such as refrigerators, heating, and lighting, continue to operate, providing peace of mind during emergencies.
How do I determine the right size of generator for my home?
To determine the right size of generator, first calculate the total wattage of the appliances and systems you wish to power during an outage. Add the starting wattage (the amount needed when the appliance first turns on) and the running wattage (the amount needed during operation) for each. Consider using a generator sizing calculator or consult a professional for accurate assessment.
What appliances can I power with a backup generator?
Common appliances that can be powered with a backup generator include refrigerators, freezers, sump pumps, heaters, air conditioners, and essential electronics like laptops and televisions. Always prioritize critical items based on your household needs.
Should I choose a portable or whole-house generator?
Your choice between a portable and a whole-house generator will depend on your power needs. Portable generators are more affordable and can power basic appliances, while whole-house generators provide a permanent solution that can power your entire home, even during long outages.
What fuel types do backup generators use?
Backup generators commonly run on gasoline, propane, natural gas, or diesel. Each fuel type has its advantages; for example, natural gas is convenient and clean, while propane can be stored easily for extended use. Consider the availability of fuel type in your area when making a choice.
How often should I run and maintain my backup generator?
It's recommended to run your backup generator for at least 30 minutes every month to keep it in good working condition. Regular maintenance, including oil changes and checking filters, should follow the manufacturer's guidelines, typically every 100 to 200 hours of use or annually.
What is the average cost of a backup generator?
The cost of a backup generator can vary significantly based on its size, type, and features. Portable generators can start around a few hundred dollars, while whole-house generators can sell for several thousand dollars, including installation costs. Assess your budget and power needs when considering options.
Can I install a backup generator myself?
While some portable generators can be set up easily without professional help, whole-house generators usually require specialized installation due to electrical wiring and local code compliance. It’s best to hire a licensed electrician for whole-house systems to ensure safety and proper operation.
What is the noise level of backup generators?
Noise levels can vary depending on the generator’s size and type. Portable generators tend to be louder, while whole-house generators are designed to operate more quietly. When selecting a generator, check the decibel rating and consider noise restrictions in your area.
How long can a backup generator run on a single tank of fuel?
The runtime of a backup generator depends on the fuel type and load. Generally, portable generators may run for about 5-12 hours on a full tank, while whole-house generators can run longer if connected to a stable fuel source, such as natural gas. Always check the manufacturer’s specifications for accurate information.
