Tesla announces Powerwall 3P with native three-phase inverter

Tesla has announced the Powerwall 3P, a new variant of its home battery with a native three-phase inverter built into a single unit. The product, announced for the German market first, eliminates the clunky workaround that previously required European homeowners to install up to three separate Powerwalls to achieve whole-home backup on the continent’s standard three-phase residential grids. Sign-ups are now live on Tesla’s website.


Tesla has positioned the 3-phase version to deliver roughly the same energy capacity as the regular Tesla Powerwall 3 (≈13.5 kWh), but with a native three-phase inverter.


Expected Power Output (based on Powerwall 3 platform)


Continuous power: ~11–11.5 kW


Peak power (short bursts): ~15–16 kW


Across phases: Power is balanced automatically over the 3 phases

Sodium-ion batteries are emerging

Sodium-ion batteries are emerging as a serious complement to lithium-ion technology, offering a cheaper, more abundant and geopolitically resilient solution for energy storage. Unlike lithium batteries, sodium batteries rely on sodium — one of the most abundant elements on Earth — and can be produced without rare or critical metals such as lithium, cobalt, nickel or graphite.


This material advantage is driving growing interest from governments and industry as supply-chain risks and costs rise. Typical sodium-ion chemistries use iron, manganese and hard carbon, dramatically reducing exposure to volatile commodity markets and environmentally sensitive mining operations.


In real-world applications, sodium batteries are already moving beyond the laboratory. They are being deployed in grid-scale energy storage, renewable energy buffering, industrial backup systems and low-speed electric mobility such as scooters, forklifts and entry-level electric vehicles. China currently leads commercialization, with companies like CATL, BYD and HiNa Battery rolling out sodium-based storage systems and…
