Home Battery Storage FAQ

How much does a home battery cost installed?

Partial backup starts near $8,250. One full-size 13.5 kWh unit typically runs $11,000–$16,500. Whole-home coverage with two units can reach $33,000.

Can I add a battery to my existing solar panels?

Usually yes. AC-coupled batteries retrofit onto most existing systems without touching the panels. The installer confirms your inverter setup and panel capacity, then quotes the retrofit as its own job.

How long will a battery run my house?

A 13.5 kWh unit typically carries a home's essentials, refrigerator, lights, internet, and outlets, through an evening or overnight outage. Whole-home coverage or longer runtimes need more capacity, which is why we price by kWh.
