Tesla is expanding its home energy lineup in Europe with a new product designed specifically for the region’s electrical infrastructure.
According to a report from Not a Tesla App, Tesla has officially confirmed the launch of the Powerwall 3P in Germany — a new three-phase version of its popular home battery backup system. The company has already launched a sign-up page, with the product expected to roll out soon.
The key difference comes down to how homes are wired. In North America, most houses run on single-phase power, making it relatively simple for a standard Powerwall 3 to back up an entire home. In Germany and much of Europe, however, residential properties commonly use three-phase power. This setup is more efficient for running heavy appliances like induction cooktops, heat pumps, and EV chargers — but it has historically complicated Powerwall installations.
Until now, European homeowners often had to install three separate Powerwall units — one for each phase — to achieve true whole-home backup. That solution was both expensive and complex. A single-phase Powerwall could only connect to one phase (L1, L2, or L3), leading to phase imbalance issues and limiting which circuits would remain powered during an outage.
The new Powerwall 3P addresses this by integrating a native three-phase inverter. Instead of stacking three units, a single Powerwall 3P can connect to all three phases simultaneously, balance loads evenly, and power three-phase equipment directly. In short, it’s a far cleaner, one-box solution tailored to Europe’s grid standards.
While the Powerwall 3P can charge from the grid, it also pairs seamlessly with Tesla’s solar panels, allowing homeowners to store excess sunshine during the day for use at night or during an outage. The launch comes as Tesla Energy continues to scale globally. Powerwall installations surpassed 1 million units worldwide last fall, highlighting strong demand for home energy storage.
Interestingly, while the Powerwall 3P is aimed at Europe, it could also find use cases in North America, particularly for small businesses operating on three-phase commercial power that want backup capability without stepping up to Tesla’s utility-grade Megapack system.
With the Powerwall 3P, Tesla is clearly signaling that its energy ambitions extend well beyond EVs — and that localization matters.
