Choose Your Backup Level
What Do You Want to Keep Running During an Outage?
Essential Loads
Keep the most important things running during an outage, such as your refrigerator, lights, internet, medical equipment, and selected outlets. We'll help you estimate how much backup power those essentials require.
Whole-Home Backup
Keep most or all of your home powered during an outage, including larger loads such as air conditioning, well pumps, electric appliances, and other household systems. We'll help you estimate the power and battery or generator capacity you may need.
Decide whether you want backup power for just the essentials or enough capacity to keep most or all of your home running. We'll help you understand the difference and estimate how much power each approach requires.
