Question 1

How do I know if I need a backup generator for my home?

Accepted Answer

You likely need a backup generator if you experience more than 2-3 power outages per year, live in an area prone to severe weather, have medical equipment requiring electricity, work from home, or have food storage that could spoil during extended outages. Use a blackout risk assessor to evaluate your specific situation based on outage history, local grid reliability, and your household's critical power needs.

Question 2

How long can the average power grid last during a major blackout?

Accepted Answer

During major blackout events, power grid restoration typically takes between 1 to 7 days depending on the cause and severity. Weather-related outages average 3-5 days of restoration, while equipment failures may be resolved in 4-24 hours. Historic events like the Texas 2021 freeze showed some areas without power for over 5 days, with water systems failing within 24-48 hours of grid failure.

Question 3

What size battery backup do I need for a home during a power outage?

Accepted Answer

For essential home backup during a blackout, a 5-10 kWh battery system can power critical circuits (refrigerator, lights, phone charging, furnace fan) for 12-24 hours. A whole-home backup typically requires 15-20 kWh or more. The exact size depends on your household's daily consumption, the number of critical appliances, and how many days of autonomy you need. A blackout risk assessment helps determine the right capacity for your situation.
