The Tesla Powerwall is a rechargeable lithium-ion battery designed for residential energy storage and backup power. Installed as part of a home electrical system, it stores energy from the grid or on-site generation for use when required, including during outages.
The unit integrates an inverter and energy management software to control charging and discharging, allowing homeowners to optimise electricity use and increase resilience. When paired with renewable energy systems, the Powerwall can support reduced reliance on grid electricity and enable greater use of self-generated power.
Its compact wall-mounted design allows for flexible installation in residential settings.
