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
That means instead of 11 kW on just one phase, the system can distribute that total output across all three phases (for example ~3.7 kW per phase if evenly loaded).
