Powerwall

Tesla Powerwall

Imagine a minimalist, futuristic panel mounted seamlessly on the wall of a garage or the side of a house. About the size of a small refrigerator door, the Powerwall boasts a smooth, glossy white or black finish with subtle curves that give it a polished, high-tech aesthetic. The front is marked simply with the “TESLA” logo — understated, yet unmistakably bold.

Inside, it houses 13.5 kWh of lithium-ion battery capacity, capable of powering your entire home through the night or during a grid outage. It silently charges from solar panels during the day or draws electricity from the grid when rates are low, then powers your home when rates are high or the grid goes down.

The system is intelligent — through the Tesla mobile app, you can track energy usage in real time, see how much solar you’re generating, and even isolate your house from the grid during blackouts with a feature called Backup Gateway.

Use Cases:

• Power your home at night using solar energy collected during the day.

• Keep essential appliances running during a blackout (lights, fridge, Wi-Fi).

• Avoid high electricity bills by using stored energy during peak rate hours.

• Go completely off-grid when paired with enough solar and multiple Powerwalls.

Key Specs (as of latest model):

• Usable Capacity: 13.5 kWh

• Power Output: 5 kW continuous / 7 kW peak

• Scalable: Up to 10 units can be stacked together

• Installation: Indoor or outdoor

• Warranty: 10 years

When Paired with Solar:

Together with Tesla Solar Panels or Solar Roof, Powerwall transforms a home into a self-sustaining energy ecosystem — quiet, clean, and largely independent from utility companies
