Tesla Powerwall 3

Building on the success of its predecessors, the Powerwall 3 retains the same 13.5 kWh energy capacity in Powerwall 2. However, the noteworthy upgrade comes in the amount of power it can provide — an increase to 11.5 kW continuous power, instead of 10 kW peak on the Powerwall 2.

The Powerwall 3 also had its on-grid power increase substantially from 5.8 kVA (4.64 kW) to 11.5 kW, both continuously.

A major distinguishing feature is the fully integrated solar inverter with a capacity to handle up to six solar inputs, facilitating high-efficiency direct solar connections. This move showcases Tesla’s commitment to advancing clean energy solutions, setting a new benchmark in solar-to-grid energy conversion efficiency pegged at a staggering 97.5%.

Tesla has slightly redesigned the Powerwall 3, making it compact yet heavier compared to its predecessor. With dimensions of 43.25 in x 24 in x 7.6 in and a weight of 287 lbs, it seeks to blend power with aesthetics. Installation includes the promise of seamless backup transition and resilience against flood and dust, adhering to North American safety and EMI standards.
