Powerwall
Tesla Powerwall is a home battery storage product that stores electrical energy from solar generation or the grid for later household use. It is a stationary battery product rather than an EV traction battery. Powerwall can be combined with home solar and backup-power functions depending on the installation. Tesla's current Powerwall 3 includes an integrated solar inverter. The term is a Tesla product name, so it should not be used as the generic name for all residential battery-energy-storage systems.
