Will a battery keep my home running?
Start with what must stay on.
STEP 1 / 3
Pick your must-haves.
Start with lights, a fridge, phone charging and other key needs. Ask which circuits a proposed battery will power.
Do not rely on a general home battery plan for life-support needs. Make a separate emergency plan.

Treat AC as a separate question.
Air conditioning, ovens and EV charging can draw much more power. Whole-home backup needs a design sized for your actual loads.
Runtime depends on battery capacity, what is running, charge level and weather. There is no one-size-fits-all runtime.
Plan for the outage, too.
Solar alone generally shuts off in a power outage. Backup needs compatible equipment and safe isolation from the grid. Ask how the battery recharges.
Follow local evacuation and safety orders. A battery does not make a home safe during every storm.
