The Tesla Daily Powerwall system is a wall-mounted battery system for residential or commercial use. Its rechargeable lithium-ion battery pack provides energy storage for solar self-consumption, load shifting, backup power, or any high-throughput application. Powerwall’s electrical interface is provided by an internal isolated bi-directional DC/DC converter that controls the charge and discharge of the battery for integration with utility-interactive solar inverters.
Powerwall achieves unprecedented levels of safety in home energy storage. It is a factory-assembled, fully certified unit that contains no user-serviceable parts. The microprocessor controlled DC/DC converter is electrically isolated from the internal battery and eliminates any user access to voltage on the unit’s field wiring terminals for installation, service, or shutdown.
