Tesla recently presented the third generation of Powerwall, the home system for storing photovoltaic electricity . The big news is that this time there is an integrated solar inverter, which makes it a more efficient system. complete compared to the Powerwall 2 which was in fact just a battery, it also improves energy throughput.
Aesthetically, the differences with the previous Powerwall are few: you are faced with a white wardrobe with a glossy front, always white. Instead of the writing “Tesla”, however, there is now only the now well recognizable "T" stylized. The internal battery remains a 13.5 kWh; Tesla promises the possibility to expand the capacity up to 40.5 kWh, and that up to 6 solar inputs can be accepted simultaneously.
