More About the Powerwall 3
The Powerwall 3 has an integrated solar inverter, allowing up to 20 kW of solar to be connected to the system (more than twice the capacity of the Powerwall 2), capable of generating plenty of power for your home and battery. This combination of equipment offers savings on home solar and battery combo systems with fewer system components.
Tesla’s updated the battery chemistry with this new addition to their battery lineup as well. The Lithium-Ferro-Phosphate (LFP) battery cells is another upgrade from the Lithium-Nickel-Manganese-Cobalt (NMC) used in the Powerwall 2, offering a safer (improved thermal stability) and more sustainable (no Cobalt) home backup solution.
