Impressive Specifications:

According to an interview with a Tesla applications engineer at All-Energy 2023 in Melbourne, Australia, the Powerwall 3 is set to feature 6 x MPPTs and can be coupled with a maximum of 20kW of solar power. This makes it a power-packed system, surpassing its predecessor, the Powerwall 2. Moreover, the Powerwall 3 is expandable, allowing for the addition of up to 3 smaller battery modules, reaching a combined total of 54kWh of energy storage.

Hybrid Design and Efficiency:

Unlike the Powerwall 2, the Powerwall 3 is an all-in-one (hybrid) system that includes a solar inverter. This means it can directly charge the battery from connected solar panels, making it more efficient. The Powerwall 3 boasts a charging efficiency of 96-97%, compared to the AC-coupled Powerwall 2’s efficiency of 92-93%. The increased efficiency of the Powerwall 3 translates to more power available for your home’s energy needs.

Unleashing Power and Performance:

One of the standout features of the Powerwall 3 is its impressive power rating. With a continuous power output of 11.5kW (on-grid), it offers 60% more power than its predecessor. This significant increase makes it an ideal choice for high-demand households equipped with solar EV charging and other energy-intensive appliances. The backup power rating is estimated to be the same as the continuous power output.

Peak Power Output and Surge Capacity:

Although the peak power rating is not officially listed, it is speculated that the Powerwall 3 offers around 10kW of peak off-grid power for 10 seconds. Additionally, the Powerwall 3 boasts a remarkable locked rotor amps (LRA) rating of 150A, which allows it to start motors or power large appliances with ease. With its substantial power output and surge capacity, the Powerwall 3 is designed to meet the demands of modern households.

Compact Design and Enhanced Cooling:

Tesla has engineered the Powerwall 3 to be more compact, with dimensions that are smaller than the previous Powerwall 2. Despite its smaller size, it still manages to incorporate a solar inverter and impressive power capabilities. The Powerwall 3 utilizes an improved cooling system, featuring an exposed cast aluminum housing that acts as a heat sink. This design enables efficient heat dissipation and helps regulate internal temperature, ensuring optimal performance.
