Integrated solar + battery. Whole-home backup. Everyday savings.
Powerwall 3 combines a high-capacity battery with an integrated solar inverter, so one unit can accept DC solar directly and deliver whole-home backup with fast, seamless transitions. Manage everything in the Tesla app—optimize for bill savings, backup, or self-consumption.
Each unit provides up to 11.5 kW AC continuous power and supports up to 20 kW DC solar with six MPPTs, making it a compact, scalable backbone for most homes.
Up to 11.5 kW continuous AC output keeps more of your home running during outages.
Directly connects up to 20 kW of DC solar without needing a separate inverter.
Add expansion units or stack multiple Powerwall 3s for greater storage and higher power output.
Control, monitor, and optimize your system in real time using the Tesla app.
