TESLA POWERWALL 3
The Powerwall is a compact home battery that stores energy generated by solar or from the grid. You can use this energy to power the devices and appliances in your home day and night, during outages or when you want to go off-grid. With customizable power modes, you can optimize your stored energy for outage protection, electricity bill savings and more.
A Powerwall can power your entire home with one unit, making whole-home backup protection more affordable. Each unit is self-contained with an integrated solar inverter for added efficiency, resulting in fewer parts and faster installation. This helps make multi-unit systems more affordable and system expansions easier in the future.
Backup protection only works when your backup system is reliable. Powerwall is designed to withstand extreme weather conditions and harsh environments. It can maintain normal operation in cold temperatures, high humidity and flooding in two feet of water.
