The Powerwall 3 part number and serial number can be found on the left side of the unit. Otherwise, Powerwall 3 has an IMP of 13 A. Powerwall 3 with mid-circuit interrupters is an RS2 system for PV Rapid Shutdown. 6When PV strings are combined on the roof and the DC input current exceeds the MPPT rating, a jumper can be used to combine two MPPTs into a single input to intake DC current up to 30 A IMP / 38 A ISC (or 26 A IMP / 30 A ISC if Powerwall 3 is labeled with 13 A IMP / 15 A ISC).

Round-trip efficiency improved from 90% to 97.5%. The unit is slightly larger but eliminates extra hardware, making the total installation footprint smaller. Usable capacity remained the same at 13.5 kWh. Tesla Powerwall 3 Official Product Page (specifications and ordering) A single Tesla Powerwall 3 costs between $9,200 and $12,000 fully installed, depending on your location and installer. The federal residential credit (IRC Section 25D) expired Dec 31, 2025 — a battery you own and install in 2026 gets $0 federal, so that installed range is what you pay. The Tesla Powerwall 3 is a 13.5 kWh home battery with a built-in solar inverter, 11.5 kW continuous power output, and 97.5% round-trip efficiency. It replaced the Powerwall 2 in 2024 with a complete redesign: one box instead of two, more than double the continuous power, and no separate Gateway required. Here are the full specs, what changed, how many you need, and what it actually costs installed. The 13.5 kWh figure is usable capacity, not total. The Powerwall 3 reaches 97.5%. That improvement comes largely from eliminating one conversion step, since the solar DC goes directly into the battery without an external inverter in the path. Same capacity. Usable capacity stayed at 13.5 kWh. Tesla focused the upgrade on power and integration rather than raw storage.
