The Tesla Powerwall 3 is a next-generation home battery system with a fully integrated solar inverter. It stores solar energy produced during the day and powers your home when you need it most — during peak rate hours, grid outages, or at night.
Unlike previous models, a single Powerwall 3 unit can back up your entire home thanks to the new Tesla Smart Meter, which intelligently manages your home's electrical panel for whole-home backup protection.
Powerwall 3 is designed for simple installation, maximum efficiency, and long-term durability — even in extreme weather conditions.
Already have solar? Powerwall 3 can be tied into any existing solar system for battery backup and peak-hour savings. Planning a new system? Its integrated inverter works seamlessly with new solar installations — giving you one streamlined, efficient setup.
Monitor everything from your phone. The Tesla app gives you real-time visibility into your solar production, battery storage, home energy usage, and grid status — all from the palm of your hand.
Why Tesla Powerwall 3?
Whole-Home Backup
A single Powerwall 3 can back up your entire home — lights, fridge, AC, Wi-Fi, garage door, and EV charger. Automatic switchover in milliseconds.
Built-In Solar Inverter
The Powerwall 3 includes an integrated solar inverter, eliminating the need for a separate string inverter. Simpler installation, fewer components, lower cost.
13.5 kWh Storage
Each Powerwall 3 stores 13.5 kWh of usable energy. Stack up to 4 units for 54 kWh of total storage — enough to power most homes for 24+ hours.
Peak Hour Savings
Store solar energy during the day and discharge during expensive peak hours (4–9 PM). Essential for maximizing savings under NEM 3.0 and time-of-use rates.
Storm Watch
When the National Weather Service issues a severe weather alert, Powerwall automatically charges to 100% from the grid to prepare for potential outages.
25-Year Warranty
Tesla backs the Powerwall 3 with a 25-year warranty — one of the longest in the industry. That's decades of reliable backup protection.

How Powerwall Works With Solar
Daytime
Solar panels generate electricity. Powerwall charges first, then your home uses the rest. Any surplus goes to the grid.
Peak Hours (4–9 PM)
Powerwall discharges stored energy to power your home during the most expensive rate period. You avoid paying Edison's peak prices.
Outage
Grid goes down? Powerwall instantly takes over. Your lights stay on, your fridge keeps running, and your Wi-Fi stays connected.
