Tesla Powerwall 3
The most powerful home battery Tesla has ever made. 13.5 kWh of storage, 11.5 kW of continuous power, and whole-home backup — installed by Solergy's certified team.
Power Everything. Even When the Grid Can't.
Powerwall 3 is Tesla's most capable home battery — integrating solar, storage, and backup into one sleek unit designed for whole-home energy independence.
Whole-Home Backup Power
Seamlessly detects grid outages and switches to backup mode in milliseconds — keeping your AC, fridge, lights, and essentials running without interruption.
Fully Integrated with Solar
Supports up to 20 kW DC of solar input with 6 built-in MPPTs. Excess solar charges your Powerwall automatically throughout the day.
Tesla App Control
Monitor energy production, battery charge level, and home consumption in real time from anywhere using the Tesla app on your phone.
High Load Start Capability
Starts heavy loads up to 185A LRA — meaning a single Powerwall 3 can handle the demands of most homes, including AC units and appliances.
Grid Services & Self-Sufficiency
Participate in grid services programs or optimize for self-consumption and time-based control to maximize savings on your electricity bill.
Revenue-Grade Metering
Built-in revenue-grade AC metering (±0.5%) gives you precise visibility into your home's energy flow and solar production.
