Battery backup
Added energy resilience for your home.
A standalone battery backup system can keep important parts of your home running when the power goes out — with or without solar.
What to know
How battery backup works for homeowners.
What a battery backup system does
It stores electricity and supplies it to your home when grid power is unavailable.
Which loads may be supported
Typically essentials like lighting, refrigeration, internet, and certain outlets or systems. Larger loads depend on capacity and configuration.
Capacity and backup duration
How long a battery lasts depends on its capacity and what's running. More batteries or fewer connected loads extend backup time.
