Tesla Powerwall is a rechargeable lithium-ion battery designed to store energy at a residential level for backup power and self-consumption of solar power generation. Powerwall 2.0 can store up to 13.5 kWh of clean energy that with or without Solar can provide power to your home even when the grid is down. The unit mounts seamlessly on a wall and is integrated with the local grid to harness excess power and give customers the flexibility to draw energy from their own reserve.
The Tesla Powerwall is sized for day-to-day use at your home and is often paired with a solar panel system. When your solar panels produce more electricity than you can use in your home, you can store the excess electricity in the battery system instead of sending it back into the grid.
When the grid goes down, solar energy will continue to power your home and charge your Powerwall, with 2 power walls you can have up to 7+ days of continuous power during an outage.
Powerwall can detect an outage, disconnect from the grid, and automatically restore power to your home in a fraction of a second. You will not even notice that the power went out. Your lights and appliances will continue to run without interruption.
