For more information, refer to the Tesla Powerwall++ Warranty for your region at tesla.com/support/energy/

powerwall/documents. Powerwall++ Owner's Manual 5 CARE AND MAINTENANCE Environmental Requirements Powerwall++ is capable of charging and discharging within the operating temperature range specified below. At the extremes of the temperature range, Powerwall++ may limit charge or discharge power to improve battery lifespan. For best performance, the average ambient temperature over the systems lifetime should fall within the optimum temperature range specified below. Operating Temperature Optimum Temperature Care and Cleaning

-20C to 50C (-4F to 122F) 0C to 30C (32F to 86F) If it is installed outside, keep the front of Powerwall++ clear of leaves and other debris to maintain optimal airflow. CAUTION: Do not lean on, stack anything on top of, or hang anything from Powerwall++ or from wires or conduit leading to Powerwall++. CAUTION: To clean Powerwall++, 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++ or expose Powerwall++ to flammable or harsh chemicals or vapors. Maintenance Powerwall++ and the Gateway do 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. Powerwall++ Owner's Manual 6 ABOUT POWERWALL++

System Design Powerwall++ is a fully integrated AC battery and PV inverter system for residential or light commercial use. Its rechargeable lithium-ion battery pack provides energy storage for solar self-consumption, load shifting, or off-grid use. The Tesla Energy Gateway controls the operation of the system and allows remote monitoring of energy usage. Excess solar energy can be stored and used at night to reduce or eliminate dependence on utility power. Whole Home Backup System A Powerwall++ system for whole home backup is designed to store energy from the grid or solar, and power the entire home during a grid outage. Whole Home Backup with Backup Switch Powerwall++ Owner's Manual 7 ABOUT POWERWALL++

Whole Home Backup with Backup Gateway 2 Partial Home Backup System A Powerwall++ system for partial home backup is designed to store energy from the grid or solar, and can power some home loads during a grid outage. These loads are selected during the system design phase, and the installer configures the system at installation to exclude all other loads from backup. Powerwall++ Owner's Manual 8 ABOUT POWERWALL++

System Components Powerwall++

Component Description Powerwall++ is the rechargeable battery and solar inverter that stores energy for your home. Every system contains at least one Powerwall++, with additional Powerwall++

installed, depending on your homes energy consumption. Powerwall++ is installed with one of the following Tesla devices. Tesla Part Numbers 1707000-xx-y Tesla Energy Equipment Component Description Tesla Part Numbers The Tesla Backup Gateway 2 is installed in partial and whole home backup systems. 1232100-xx-y The Backup Gateway 2 controls the operation of the system, allows remote monitoring of energy usage, and manages the transition to and from backup operation. The Tesla Backup Switch is installed in whole home backup systems. When installed with the Tesla Backup Gateway 2, it detects grid outages and manages the transition to and from backup operation while the Backup Gateway controls the operation of the system. 1624171-xx-y Powerwall++ Owner's Manual 9 ABOUT POWERWALL++

Additional Equipment Component Description The Remote System Shutdown Switch, when installed, is a means of turning off Powerwall+

+ to disable charging and discharging. Push in on the switch to disable Powerwall++ and initiate rapid shutdown of solar production. To turn the system back on, twist the red handle clockwise, allowing it to return to the ON position. Powerwall++ Owner's Manual 10 ABOUT POWERWALL++

Powerwall++ Overview Powerwall++ includes the following components and features:

Component/Feature Name 1 2 3 4 Air Intake Air Exhaust On/Off Switch LED Indicator Powerwall++ Owner's Manual 11 SYSTEM OPERATION The Gateway provides control and monitoring capability through the Tesla app. During normal operation, Powerwall++ is controlled by the Gateway, and the Powerwall++ On/Off switch should remain in the ON position. When troubleshooting Powerwall++ operation, it may be necessary to turn off Powerwall++ or refer to its LED indicator to confirm that it is operating properly. WARNING: Do not operate Powerwall++ unless all covers are in place. WARNING: Do not disconnect anything from or add anything to Powerwall++. CAUTION: Do not try to communicate with Powerwall++ using third party tools or diagnostics between Powerwall++ and the Gateway. Monitoring Your System Using the Tesla app, you can monitor the system operation from your mobile device, including the following:

Real-time power usage Energy consumption history Relative amounts of energy used from solar, grid, and Powerwall storage To download the latest version of the Tesla app, visit tesla.com/support/tesla-app. Troubleshooting If the system is not working correctly, perform the following steps. CAUTION: Powerwall and the Gateway are not user-serviceable and must be repaired by a Tesla Certified Installer. WARNING: Do not open the deadfront cover inside the Gateway. Exposed wiring can present a risk of electrical shock. Check the LED on the front of Powerwall++ to determine its status:

LED State On (solid) On (fading) System idle, no faults System enabled and charging or discharging Indication On (flashing) Fault present Off System not enabled or switched off If it is not possible to communicate with the Gateway through the Tesla app, ensure that the home Internet connection is working. Powerwall++ Owner's Manual 12 SYSTEM OPERATION If the Gateway and Powerwall++ are both unresponsive, it may be necessary to turn off or power cycle the system. Note that power cycling the system must be done in the proper sequence as defined below. WARNING: On Powerwall++ systems with interconnected solar, always turn off the solar inverter or disconnect the solar source before turning off the Powerwall++ unit. 1. Turn off Powerwall++ by setting its On/Off switch to the OFF position. 2. Turn off the AC breaker to Powerwall++. 3. Turn off the AC breaker to the Gateway (for whole-home backup systems, this may be a breaker inside the Backup Gateway). 4. Wait for at least one minute. 5. Turn the AC breakers back on. 6. Turn on Powerwall++. Powerwall++ Owner's Manual 13 SYSTEM OPERATION Backup Troubleshooting If a brownout or blackout is experienced during backup operation, reduce the loads and check that the load breakers have not opened. NOTE: See https://www.tesla.com/support/energy/powerwall/own/best-practices-during-

power-outages for best practices to extend the backup duration of your system during an outage. If it is necessary to restart the Backup Gateway or Backup Switch, Tesla support may direct you to press the Reset button on the device. If it is necessary to manually reconnect to the grid, Tesla Support may direct you to operate the manual override switch on the Backup Gateway or the Backup Switch. Component Name 1 2 3 4 Backup Gateway / Backup Switch RESET button Backup Gateway / Backup Switch manual override switch Backup Gateway circuit breaker (in most whole-home backup systems) Backup Switch conduit hub1 1The Backup Switch conduit hub must be removed to access the Backup Switch Reset button or manual override switch. To remove the conduit hub, use a Phillips PH2 screwdriver to loosen the (3) captured fasteners holding it in place, then remove the hub. Once any service actions have been completed, replace the conduit hub and tighten the (3) fasteners. Powerwall++ Owner's Manual 14 SYSTEM OPERATION Operating the Backup Switch Manual Override WARNING: Improper operation of the manual override switch may damage the unit, and could void the product warranty. Do not remove the conduit hub or operate the manual override switch unless directed to do so by Tesla Support, or in the event that the grid is present but you are experiencing an outage. Contact Tesla Support if you are not sure whether you should operate the manual override switch. WARNING: Do not make any modifications or adjustments to the Utility Meter; only interact with the Backup Switch. To manually connect the system to the grid, push the Backup Switch manual override switch in. Backup Switch LED Status The Backup Switch LED is located near the Reset button under the conduit hub. To view the Backup Switch LED and determine its status, remove the conduit hub as described above. LED State Indication On (solid) Power is on, communication established with Powerwall+
