Now, let’s explore the hardware of the Powerwall 3 to understand what technical improvements it brings compared to previous generations:

Integrated Solar Inverter

  • The most noteworthy upgrade is an integrated solar inverter within the Powerwall itself
  • This allows the Powerwall 3 to directly connect to solar panels without any additional equipment
  • Compatible with all major solar inverter standards for alternative solar connectivity

Increased Solar Input Capacity

  • Can utilize power from up to six solar arrays simultaneously
  • Each solar input features independent Maximum Peak Power Tracking for optimal solar harvesting
  • Substantially increases household solar energy capture vs Powerwall 2

Larger Inverter

  • 12.6 kW continuous power inverter allows full utilization of battery capacity
  • More than 2x larger than the 5 kW inverter included with Powerwall 2
  • Provides 11.5 kW of backup power, 9 kW off-grid output

Modular and Scalable

  • Designed so multiple Powerwall units can easily link together
  • Allows tweaking energy capacity to match household needs by adding Powerwalls
  • Requires only a single integrated gateway for any number of connected Powerwalls

Refined Industrial Design

  • Sleek new compact look at only 6 inches thick to seamlessly fit on garage walls
  • Easy to maintain with a simple snap-open exterior for quick access to components
  • Integrated handle and weighting make the unit easier to transport and install

With major hardware improvements across the board, the Powerwall 3 represents a huge technological leap over previous generations.

How Does The Powerwall 3 Compare To The Powerwall 2?

To fully appreciate the Powerwall 3’s upgrades, it’s useful to contrast how it stacks up against Tesla’s previous home battery model:

  • Independent Solar Inverter – By far the most significant change is the integrated solar inverter, removing the need for any additional equipment to connect the Powerwall to solar panels.
  • Higher Peak Solar Input – 6 solar inputs instead of just 2 allows the Powerwall 3 to take advantage of more on-site solar production.
  • Bigger Inverter – The upgraded 12.6 kW inverter offers ample power for utilizing the full battery capacity as well as substantial backup and off-grid outputs.
  • Redesigned Enclosures – A refreshed exterior improves aesthetics while making the new Powerwall easier to handle and access internally.
  • Firmware Upgrades – Under the hood software enhancements are not detailed but are likely to provide performance optimizations.
  • Larger Usable Capacity – While rated capacity remains the same, usability improves from 13.5 kWh on Powerwall 2 to 14 kWh on Powerwall 2 thanks to other system upgrades.

With major hardware and software improvements across the board, the Powerwall 3 is more than just an incremental upgrade over previous versions.

What’s The Tesla Powerwall 3 Price Per kWh And Estimated Cost?

Pricing details on the Powerwall 3 are limited for the moment. We know that historically, Tesla has aimed to achieve ~$100 per kWh cost targets for its home battery solutions.

Extrapolating from the Powerwall 2’s ~$7,500 price for a 13.5 kWh usable capacity, we could expect the Powerwall 3 to retail somewhere around $10,000 to $11,000 per unit.

However, no definitive Powerwall 3 pricing has been shared by Tesla yet. The cost will also vary considerably depending on your location and installer.

We should learn more details as we get closer to the 2024 consumer launch. However, expect the Powerwall 3 to command at least a moderate premium over previous generations given the major hardware additions.

For homeowners weighing Powerwall 2 vs 3, the newer model likely justifies spending extra for most. The integrated solar connectivity alone is a potential $2,000+ value-add that pays long-term ownership dividends.

Still, for more budget-focused buyers, purchasing previous-gen Powerwalls could become an attractive option as inventories clear in 2023. This especially applies if you already have adequate solar infrastructure in place.
