What is the Tesla Powerwall?
The Tesla Powerwall is a solar storage battery that allows you to maintain a sustained power supply during the day or night. This battery energy storage system allows you can to store the extra electricity generated by your panels to use as backup in the event of a power outage or when your panels aren’t actively converting the energy into electricity. With the ability to work with or without solar, the Powerwall allows you to store energy for later use.
How does it work with solar?
Powerwall integrates with solar to store any excess energy generated during the day and makes it available when you need it, minimizing your reliance on your utility. Each Powerwall system has at least one Powerwall and a Tesla Gateway, which monitors energy, metering, and management for the system. It’s also equipped with a Backup Gateway that receives over-the-air updates.
Solar panels convert the sun’s rays into electricity, supplying renewable energy to your home throughout the day and charging your Powerwall. Powerwall is charged by solar during the day, when the solar panels are producing more electricity than the home is using. Powerwall then stores that energy until it’s needed, like at night or when the utility grid is offline during a power outage. Each day, solar recharges the Powerwall, giving you a fresh cycle of clean, renewable energy.
How does it combat power outages?
Powerwall can provide days of continuous power during an outage when managed efficiently. When the grid goes offline, solar energy will continue to power your home and charge your Powerwall. Without Powerwall, solar will shut down during an outage. Powerwall is self-powered, meaning you can depend on Powerwall and solar to meet all your home’s energy needs, day or night.
Tesla’s Powerwall detects grid outages and automatically becomes your home’s main energy source. With Powerwall, you can protect your home from the next power outage and keep your lights on, phones charged, and refrigerators running without skipping a beat.
