Home Backup & Resilience

Battery systems that keep the fridge, sump pump and key circuits running through an outage.

Home backup power keeps your fridge, sump pump, and a few key circuits running through a grid outage without the fumes, noise, or fuel runs of a gas generator. This collection covers hybrid battery systems built to sit in a garage or utility closet and take a charge from solar, grid, or a portable generator, so you are covered whether the outage lasts an hour or several days. Choose based on how much of your house you need to power and for how long: check the continuous output against your panel's critical circuits, and the battery capacity against how many hours of runtime you actually need.
