What it costs, and what it costs after rebates
Before rebates, expect roughly $12,000 to $15,000 installed for a Powerwall 3. The exact figure depends on your switchboard, whether you want whole-home backup, and any inverter work. The federal Cheaper Home Batteries discount then takes around 30% off, and your state incentive stacks on top.
