Tesla Powerwalls work in conjunction with solar PV panels, which harness the abundant power of the sun. Powerwalls store the excess energy generated by the panels (as well as the grid) in a rechargeable lithium-ion battery.

The stored energy is converted from direct current (DC) into alternating current (AC) by an integrated inverter, which allows it to be used for household appliances.
