Tesla Launches Powerwall 3P — A Three-Phase Battery Built for European Homes
4 min read read
Tesla launched a three-phase version of the Powerwall 3 on April 23, 2026, called the Powerwall 3P. It's the first Tesla home battery designed specifically for the three-phase electrical grids common in Europe and Australia, and it folds the battery, hybrid inverter, and home energy management system into one outdoor enclosure.
The Specs That Matter
| Spec | Powerwall 3P |
|---|---|
| Storage capacity | 13.4 kWh |
| AC output (continuous) | 15.4 kW |
| AC output (1s peak) | 21 kW |
| MPPT trackers | 4 |
| Max PV array input | 20.3 kW |
| PV input voltage range | 60–1,000 V |
| Enclosure rating | IP67 (outdoor) |
| Weight | 138 kg |
The system stacks. Four 3P units in parallel produce 61.6 kW continuous output and 94.5 kWh of total storage — enough to run a small commercial site or an off-grid rural home through several days of bad weather.
What's Different From the Standard Powerwall 3
The original Powerwall 3 was designed for split-phase 240V North American homes. Three-phase service is dominant in Europe and Australia, and previous Powerwall installations there required external inverters or extra hardware to bridge the phase difference.
The 3P bakes three-phase support into the unit itself. It also adds SG-Ready interfaces for heat pumps, meaning the battery can directly modulate a heat pump's behavior to soak up surplus solar — a feature European homeowners have been asking for since Powerwall 2.
What Tesla Didn't Disclose
Two things are missing from the launch material:
- Price. Tesla hasn't published a regional price. Industry analysts expect parity with the existing Powerwall 3 plus a modest premium for the three-phase electronics.
- Markets and timing. The release doesn't specify country availability or shipping timelines. Installer-only certification is required for setup, which suggests a phased rollout through Tesla's certified partner network.
"The system is delivered pre-assembled and pre-wired. Installation is limited to certified partners."
The Bottom Line
If you live in a market with three-phase service and have been holding off on Powerwall because the existing hardware needed clunky workarounds, the 3P is the unit you've been waiting for. Get a quote from a certified installer before the first batch of stock is gone — Tesla home energy products tend to have a long backlog after launch.
