Tesla has announced a new variant of its home battery, the Powerwall 3P, which features a native three-phase inverter built into a single unit. This innovation eliminates the need for European homeowners to install up to three separate Powerwalls to achieve whole-home backup on the continent's standard three-phase residential grids. The product is now available for sign-up on Tesla's website.
["The Powerwall 3P consolidates all of the previous workaround's complexity into a single box with a native three-phase inverter that connects to all three phases simultaneously and balances loads across them. This design simplifies the installation process and reduces costs for European homeowners, who can now achieve whole-home backup without the need for multiple units.", ['The company has not released detailed specifications or pricing for the 3P, but it maintains the same capacity as the standard Powerwall 3. The standard Powerwall 3 offers 13.5 kWh of usable capacity, 11.5 kW of continuous power output, up to 20 kW of DC solar input, and uses LFP battery chemistry with a 10-year warranty.', ["The Powerwall 3P's core advantage is simplification: one box, one installation, native three-phase. This design could undercut multi-component setups from rivals on total installed cost if Tesla prices the 3P competitively. The company's energy division has been growing rapidly, with a record 46.7 GWh of energy storage deployed in 2025.", ["Energy storage now accounts for 13% of Tesla's total revenue and 23% of its gross profit. While vehicle deliveries declined globally in 2025, the energy business powered ahead, with Powerwall installations surpassing 1 million units worldwide last fall. The Powerwall 3 has been disrupting the solar inverter market thanks to its integrated inverter.", ["However, there are headwinds for Tesla's energy division. The company recently recalled over 10,000 Powerwall units due to fire safety concerns, and brand toxicity is affecting vehicle sales. More installers are recommending alternative products like the Villara VillaGrid+, Sigenergy, and EcoFlow's DELTA Pro Ultra X.", ['The One Big Beautiful Bill Act has phased out federal tax credits for residential energy storage systems in the US, making international markets like Germany more strategically important for the Powerwall product line. Tesla is not launching the 3P into a vacuum, however, as several rivals already offer native three-phase solutions.', ['Enphase has been expanding across Europe with its IQ Battery 5P with FlexPhase technology, which delivers up to 70 kWh in a modular configuration and comes in both single-phase and three-phase versions. BYD offers three-phase compatibility through its Battery-Box HVE paired with the Power-Box hybrid inverter, while Sonnen provides virtual power plant integration.', ["The Powerwall 3P's native three-phase inverter simplifies the installation process and reduces costs for European homeowners. If Tesla prices the 3P competitively, it could undercut multi-component setups from rivals on total installed cost. The company's execution of this product is exactly the kind of industry-leading power electronics integration that excels at.", ["The timing of the Powerwall 3P launch is great, as Tesla is expecting a slowdown in Powerwall demand in the US. The EU market will need to pick up the slack, and the Powerwall 3P's native three-phase design makes it an attractive option for European homeowners."]]]]]]]]]
