Benefits of your Tesla Powerwall 3P
Powerwall 3P is a fully integrated solar and battery system built for homes with a three-phase electrical connection. Customers get whole-home backup, cost savings and energy independence by producing and consuming their own energy, and can manage their system in the Tesla app to meet their energy goals.
Powerwall 3P supports up to 20.4 kWp of solar across four MPPTs and delivers up to 15 kW of continuous AC power with solar, or up to 11.5 kW from the battery alone, with 21 kW of peak power for three-phase loads. A single unit can meet the power needs of most three-phase homes, and the system scales to four Powerwall 3P units and three Expansion units.
Powerwall is compact, safe and includes a built-in battery inverter, which provides easier integration and over-the-air updates for new features and functions

F.A.Q
Frequently Asked Questions
-
Why does the Tesla mobile app show power flows or values that appear inaccurate?
Power flow on the monitoring Tesla mobile app shows the instantaneous flow of power of your home energy system. On a typical day a combination of solar, grid, and Powerwall may be powering your home. Solar energy may flow to the grid when your home does not need it and Powerwall is full. When charging your Powerwall to its backup reserve level or in Backup-only mode, solar power will flow directly from solar to Powerwall while grid energy is drawn for the home.

Environmental Requirements
Powerwall 3P is capable of charging and discharging within the operating temperature range specified below. At the extremes of the temperature range, Powerwall 3P may limit charge or discharge power to improve battery lifespan.
For best performance, the average ambient temperature over the system’s lifetime should fall within the optimum temperature range specified below.
Operating Temperature | -20°C to 50°C* |
*Powerwall 3P is designed to operate in all climates and in direct sunlight, from temperatures of -20°C to 50°C. Performance may be de-rated at operating temperatures above 40°C.
Care and Cleaning
Keep the immediate area around Powerwall 3P clear of foreign objects and debris to maintain optimal airflow.
! CAUTION
Do not lean on, stack anything on top of, or hang anything from Powerwall 3P or from wires or conduit leading to Powerwall 3P.
! CAUTION
To clean Powerwall 3P, use a soft, lint-free cloth. If needed, the cloth can be dampened with mild soap and water only.
! CAUTION
Do not use cleaning solvents to clean Powerwall 3P or expose Powerwall 3P to flammable or harsh chemicals or vapors.
Maintenance
Powerwall 3P does not require pre-scheduled preventative maintenance. The only maintenance required by an owner is to keep the Powerwall unit free and clear of debris, especially around the air intake and exhaust.
The owner is responsible for ensuring the Powerwall system is operational; this can be confirmed by the white LED on the front of Powerwall 3P, or in the Tesla mobile app.
Note
If the Powerwall system is not operational for an extended period of time, this may result in damage to your system and void your Powerwall warranty.
