What is the Tesla Powerwall 2?

The Tesla Powerwall is a built-in solar battery system that has the capacity to store energy produced by solar panels or a solar roof on a residence. Since its debut in April 2015, Tesla has made the Powerwall available in several versions. The first Powerwall, sometimes known as the Powerwall 1 retrospectively, had a 6.4 kWh capacity and could provide 3.3 kW of electricity. In this series, the second-generation home battery storage device from Tesla is the Powerwall 2. It features a 13.5 kWh storage capacity and a 7 kW peak / 5 kW continuous power output.

Advantages of Tesla Powerwall 2

  • The system uses an extremely efficient battery and inverter and a battery management system that regulates the temperature, voltage, and other factors.
  • Due to their extensive experience in car battery technology, the firm has a strong command over quality control and safety. Every system undergoes rigorous testing and inspection at their Gigafactory in the United States, and the management system has a built-in multi-layered safety mechanism.
  • The Tesla Powerwall 2 is one of the best home backup batteries with a 10-year warranty. Additionally, it provides an infinite number of charge cycles, which keeps Tesla ahead of its rivals.
  • Powerwall 2 lets you keep running your house or company when there are power outages.
  • It also offers simple control from any location. You may use your mobile device to control your batteries from anywhere using the Tesla smartphone app, available for iOS and Android.
  • Every Powerwall installation comes with a full home energy monitoring system. You can always observe the energy flow in and out of your house.

Disadvantages of Tesla Powerwall 2

  • The cost of Powerwall is quite high. Tesla’s website lists three Powerwalls at $23,700, which amounts to $7,900 per unit. Additionally, the installation cost by an authorized technician will increase the total cost to approximately $10,000 per unit.
  • It is important to note that installing a Tesla Powerwall requires professional expertise, which adds an extra expense to the purchase cost.
  • The Tesla Powerwall battery is approximately two times larger than an average battery and necessitates a certain amount of space on your property for storage.
  • The battery has a finite lifespan of 10 years and will ultimately require replacement due to the degradation of battery cells over time.


The Tesla powerwall is a worthwhile investment for homeowners seeking to reduce their energy bills further. However, ensuring sufficient energy is generated is imperative to make the investment worthwhile. The Tesla powerwall is widely regarded as one of the best solar batteries currently available and represents a highly secure investment with a strong potential for return. Those seeking complete energy independence may wish to explore alternative, more affordable options. It should be noted that although the Tesla powerwall boasts the highest capacity solar battery presently available, a single unit may not be sufficient for continuous, 24/7 off-grid operation.

    La version 3 est en cours d’homologation pour la France et devrait être disponible en 2025 (peut-être fin 2024). La batterie powerwall v2 est déjà en vente au Portugal et en Italie (il suffit d’aller sur la version italienne du site tesla pour voir le prix de 6500 euros pour cette v2).
