Get a free solar savings estimate for your home — no commitment required.
The Tesla Powerwall 3 is a fully integrated home battery system that stores electricity generated by your solar panels — or from the grid during off-peak hours — and delivers it when you need it most.
When paired with a Universal Solar Direct solar installation, the Powerwall creates a complete energy ecosystem: your panels generate power, the Powerwall stores it, and your home runs on clean, free electricity around the clock.
Keep your lights, appliances, HVAC, and devices running during any grid outage — automatically.
The Powerwall detects approaching storms via the Tesla app and pre-charges to full capacity before they hit.
Charge during low-rate periods and discharge during peak hours to maximize your savings.
Enough stored energy to power an average home for a full day — or longer when combined with ongoing solar generation.
Delivers enough continuous power to run your entire home — including HVAC, EV charging, and major appliances simultaneously.
Monitor your energy production, storage, and usage in real time from anywhere. Set preferences and receive storm alerts automatically.
Tesla backs the Powerwall with a 10-year warranty, guaranteeing at least 70% capacity retention over the warranty period.
Rated for outdoor installation in temperatures from -4°F to 122°F. Works in any climate across our service area.
Add multiple Powerwall units to increase your storage capacity. Most homes start with one; larger homes often benefit from two or three.

Excess energy is stored in the Powerwall instead of being sent back to the grid.
After sunset or during grid outages, the Powerwall powers your home automatically.
The Tesla app shows your real-time energy flow, savings, and battery status.
Battery storage lets you save excess solar energy for the hours when utility power costs more, rather than sending all of it back to the grid.
During an outage, your storage system can automatically support selected loads or whole-home backup, depending on the system design.
