Important Safety Instructions 4 Powerwall Installation and User's Manual THE FUTURE OF SUSTAINABLE ENERGY Powerwall is a lithium-ion battery system that turns solar panels into an all-day resource while offering backup power in the event of a grid outage. Powerwall enables storage of renewableenergy, allowing optimized home energy control and an increasing amount of total electricity production to come from renewable sources. Reliable renewable energy improves the resiliency ofthe grid, reduces energy costs, and increases the impact of electric vehicle ownership. POWER WHEN NEEDED Powerwall enables the storage of energy from solar panels during the day, or from the grid when energy rates are low; discharges energy for backup or use at night; and automatically optimizeshome energy. Powerall thereby maximizes solar consumption and reduces energy spending. A FLEXIBLE SOLUTION Powerwall is available in a weekly cycling version and a daily cycling version. Powerwall can becharged from solar or grid power and can provide backup power. If greater amounts of energy are needed, multiple Powerwalls can be installed together to work as a larger system. Note: To secure the full 10-year product warranty, be sure to register Powerwall online. What is Powerwall?

Speciflcations 6 Powerwall Installation and User's Manual PHYSICAL REQUIREMENTS Caution: Ensure that no water sources are above or near Powerwall, including downspouts,sprinklers, or faucets. Caution: Ensure that snow does not accumulate on top of or around Powerwall. Caution: When installing Powerwall in a garage or near vehicles, keep it out of the driving path. If possible, install the Powerwall on a side wall and/or above the height of vehicle bumpers. Caution: Powerwall has a pre-installed aesthetic front cover. To prevent damage, keep Powerwall fiat on its back until just before lifting Powerwall onto the wall mount bracket. Powerwall must be installed on an upright wall that can support 115 kg (254 lbs), the maximum weight of Powerwall and its installation packaging. The wall must be fiush and extend to all edgesof the system, allowing no access to the back of the unit once it is mounted. Do not mount Powerwall horizontally or upside down. Do not mount Powerwall on a wall that is tilted backward or forward more than 5 degrees. Powerwall requires adequate clearance for installation, cabling, and airfiow. Do not mount any other objects within the clearance space illustrated below, except those explicitly required by the installation (for example, conduit or DC disconnect depending on local installation codes). Do not install anything between Powerwall and the ceiling. TEMPERATURE REQUIREMENTS Powerwall is capable of charging and discharging within the full ambient temperature range listed in the Speciflcations section. At the high and low ends of the temperature range, Powerwall may limit charge or discharge power based on battery cell temperature to improve battery lifespan. Installation in full sun raises the temperature inside the enclosure above ambient temperature. This temperature rise is not a safety risk, but can impact the performance of the batteries. Installation in full sun is not recommended to optimize the use of Powerwall. Do not install Powerwall in a room with sustained elevated temperatures, such as a boiler room. The average ambient temperature over the system's life should be 30°C (86 °F) or less. INSTALLATION REQUIREMENTS Powerwall must be installed with a compatible inverter. Wiring and conduit (where necessary)must be provided by the installer. DC disconnect requirements between Powerwall and the inverter are subject to local codes.Ensure that the installation meets local DC disconnect requirements. Check the inverter installation manual to understand site connections and overcurrent protection. All U.S. and Canada electrical installations must be done in accordance with local codes and the National Electric Code (NEC) ANSI/NFPA 70 or the Canadian Electrical Code CSA C22.1. All installations must conform to the laws, regulations, codes, and standards applicable in the jurisdiction of installation.

Step-by-Step Installation Instructions Step-by-Step Installation Instructions 9 STEP 1 - REMOVE THE BOTTOM COVER Warning: Before beginning the wiring portion of the installation, verify that the inverter ispowered off. 1. Lay the box fiat on the ground with the pallet side down. 2. Use a T25 Torx to remove 2 screws from each of the 8 blocks on the box sides (shown in the next image). Do not remove the screws near the corners of the box. 3. Lift the box lid and set it aside. 4. Use a 10 mm hex socket to remove a 10 mm external hex M6 screw on each side of the bottomcover. 5. Carefully slide off the bottom cover, ensuring that nothing is caught or bent. 6. Set the bottom cover and the 2 screws aside for reassembly after the wiring is complete. Step-by-Step Installation Instructions 10 Powerwall Installation and User's Manual STEP 2 - REMOVE THE SPLASH COVER Note: When the splash cover is removed, an Enable circuit disables the internal electronics ofPowerwall. The Enable button is located at the bottom of the circuit board, near the HV power connectors. Warning: Ensure the Enable button is not pressed by any wiring. Warning: The Enable button only disables power from Powerwall. It does not disable power from the inverter. 1. Turn off power to the relevant areas of the building at the circuit breaker panel. 2. Turn off the inverter. 3. Open the DC disconnect switch (if applicable for the installation). 4. Use a multimeter to verify that the wires from the inverter to Powerwall are not live. 5. Use a T20 Torx driver to remove the two splash cover screws. 6. Carefully remove the splash cover. Ensure that nothing is caught or bent. Set the screws andcover aside for reassembly after the wiring is complete. Warning: Use a multimeter to ensure no voltage is present on the terminals of the Powerwallcircuit board. Step-by-Step Installation Instructions Step-by-Step Installation Instructions 11 STEP 3 - SET THE COMMUNICATION SWITCHES Communication switches are located on the lower right side of the board, next to thecommunication connectors. The switches are independent and are labeled on the board: 1. Refer to the inverter manual to determine whether to use CAN or Modbus communication. 2. Set the switches based on whether the installation is one unit or multi-unit. A single Powerwall, or the last Powerwall in a multi-unit chain, has one setting. All other Powerwalls ina multi-unit chain have a second setting.

This block has three white pinsnumbered “1”, “2”, and “3” from top to bottom with a value of ‘1’ to the left and ‘0’ to the right. These switches are used to offset the address from 0 through 7. • Over Modbus, the base address is 0x18 (24). This is added to the DIP switch settings for the overall Powerwall address, with values between 0x18 and 0x1F (24-31). • Over CAN, the base address is 0x50 (80). This is added to the DIP switch settings for the overall Powerwall address, with values between 0x50 and 0x57 (80-87). Set the switches according to Powerwall position. In a multi-Powerwall conflguration, use the DIP switches to select contiguous and discrete offsets from 0 through 7 (with 0 as the flrst Powerwall,1 as the second Powerwall, continuing to 7 as the last Powerwall). Set a single Powerwall using Powerwall 0 settings.

Cutthe ends of the wires to have clean, even ends. Strip the ends of the wires enough to make solid contact in the connector, while ensuring that no bare wire extends beyond the connector edge. Depending on the conflguration of the inverter, a single 12 V power connection to the 12V thermal connector can supply power to the logic, the pump, and the fan. If the inverter has two 12 V connections, be sure to match the connection correctly within the system. The Logic 12 V mightbe called "Logic," "Always On," "Communication," or similar. The Thermal 12 V might be called "Thermal," Switched," "Pump/Fan," "Cooling," or similar. Caution: Do not splice 12 V wiring inside Powerwall. Caution: Do not add extra wiring to the left of the conduit or gland entry. Additional wiring may interfere with water ingress and high voltage shielding to the pump. Note: Use shielded communication wire and ground the shielding at one end. This reduces the possibility of noise on the communication cable. Do not ground the shield at both ends, which would create a ground loop. The 450 VDC cable is run in close proximity to the communication cabling. Therefore, ensure that all cables to Powerwall are at least 600 V insulation class and are wet or oil rated.

Lightly tug on each wire to ensure it is seated properly. 4. If any wire must be removed, push down on the appropriate button, then pull the wire out. Note: A small screwdriver might be needed to push the release down far enough. Step-by-Step Installation Instructions 16 Powerwall Installation and User's Manual At this point, all wires should be connected, leaving the communication port (J6) on the leftunused. Ensure that all wires are routed around the existing cables and towards the top left of the circuit board (at the front of Powerwall). If installing multiple Powerwalls, communication wires can be daisy-chained as described in the next section. Verify that the polarities of all power and communication cables are correct. STEP 7 - ATTACH THE SPLASH COVER 1. Align the splash cover with the circuit board. 2. Route the wires upward (away from the wall) to keep them away from the Enable button. When the splash cover is removed, the Enable button disables power to the unit for service. Warning: Misrouted wiring that keeps the button pressed in when the cover is off can create a risk of electric shock. Ensure the Enable button is not pressed by any wiring. 3. Ensure that all wires route out of the splash cover through its opening, and that wires are notpinched or kinked. 4. Ensure that the Enable button is pressed when the cover is attached. Listen for the click of the button being pressed. 5. Use a T20 Torx driver to attach the splash cover with two M4 screws. Torque to 3 Nm (27 in- lbs). Step-by-Step Installation Instructions Step-by-Step Installation Instructions 17 STEP 8 - REMOVE THE PALLET Caution: Reinstall the front cover of the box for structural stability while lifting. Note: Two people are needed for this procedure. 1. Place the box lid carefully back over Powerwall and move it sideways until the top of the box touches Powerwall inside. This leaves room for the bottom of the box to fiex without damaging Powerwall's bottom cover. 2. Align the lower edge of the box between the upper and lower wood blocks on the sides of the Powerwall. 3. Use a T25 Torx to securely attach the same 2 screws into each of the 4 upper blocks attachedto the sides of the Powerwall. Now the Powerwall is secured to the sides of the box with the top blocks, and the bottom blocks remain with the pallet. 4. Tuck all wiring into the box lid to avoid pinching or pulling the wires. 5. With one hand on the front cover and one hand under the pallet towards the top corner, both installers carefully tilt the box up onto its bottom end so that the printed Powerwall image onthe package cover is standing right side up. Ensure the box is in a stable location, such as against a wall, where it will not be bumped or tip over. 6. Remove the pallet. The mounting cleat on the back of Powerwall should now be visible, andextend past the edge of the box for easy installation. Step-by-Step Installation Instructions 18 Powerwall Installation and User's Manual 7. Verify that the box contains the following items: • Powerwall • Wall mount bracket (wall mounting fasteners are not included) • Two side covers • Two M6, 10 mm external hex bolts for the wall mount bracket side tabs (plus one spare bolt for side tabs or bottom cover) • Spare M4, T20 bolt (if needed for splash cover) If any parts are damaged or missing, contact the Tesla Energy Authorized Reseller or Tesla Energy Certifled Installer. If any damage is detected, address high voltage and other safetyrisks immediately. Do not continue the installation procedure. 8. Remove the wall mount bracket from its foam padding on the inside face of the pallet. Step-by-Step Installation Instructions Step-by-Step Installation Instructions 19 STEP 9 - DETERMINE THE MOUNTING LOCATION FOR POWERWALL 1. Using the wall mount bracket as a guide, measure the proposed location for Powerwall. Thebracket must be bolted into studs or a load-bearing wall, and allow clearance on all sides as shown in Site Requirements. 2. If mounting into wood, use a stud flnder to locate and temporarily mark the center of the wooden studs. It is important to install each fastener as close to the middle of each stud aspossible. 3. Position the thicker part of the bracket at the top, so that the fiat side is fiush with the wall. Use the bracket as a guide to mark the location of the holes on the wall. Space the holes 200, 300, 400, 500, or 600 mm (8, 12, 16, 20, or 24 in) apart. Note: Use a level tool to ensure that the bracket is level. Step-by-Step Installation Instructions 20 Powerwall Installation and User's Manual STEP 10 - INSTALL THE WALL MOUNT BRACKET 1. Drill the pilot holes to attach the wall mount bracket to the wall. 2. Install at least four washers and fasteners into the top part of the bracket and two washers and fasteners into the bottom of the bracket. There must be at least one fastener in each of the six mounting hole rows. Install the fasteners in the order shown in the numbered image. 3. Verify that the bracket is flrmly attached to the wall. 4. For easier alignment while lifting, use tape or a pencil to mark the wall at the height of the bracket lip on the outside edges of the intended mount point. Step-by-Step Installation Instructions Step-by-Step Installation Instructions 21 STEP 11 - MOUNT POWERWALL 1. With Powerwall still in its box, keeping it as level as possible, lift it so that the mounting cleatis just above the lip on the wall mount bracket. Use the tape or pencil marks on the wall as visual guides. 2. Lower Powerwall so that the cleat on the back of Powerwall flts securely over the lip on the bracket. 3. Ensure that Powerwall is centered on the bracket. When properly centered, Powerwall sits between the two protruding tabs on the bottom part of the bracket. Step-by-Step Installation Instructions 22 Powerwall Installation and User's Manual STEP 12 - REMOVE THE PACKAGING Note: Two people are needed for this procedure. 1. First person: Hold the box in place from the bottom edge, to prevent the box from slipping and damaging Powerwall's front cover. 2. Second person: Use a T25 Torx to remove the 8 screws holding the box to the wooden blocks. 3. Being careful not to bump the box into the sides or edges of Powerwall's front cover, remove the box and carefully set it aside. Note: Leave the protective sticker on the Powerwall front cover until installation is complete. 4. Use a 17 mm socket to remove the 4 bolts that hold the wooden spacer blocks against the sides of Powerwall. Remove all 4 wooden blocks. 5. Use a T30 Torx driver to remove the screws from the metal L-brackets and discard. 6. Use a 10 mm socket tool and the 2 provided M6 external hex bolts to secure Powerwall to the lower tabs of the wall mount bracket. Torque to 7 Nm (62 in-lbs). Step-by-Step Installation Instructions Step-by-Step Installation Instructions 23 STEP 13 - FEED WIRES THROUGH THE CONDUIT PLATE OR CABLE GLAND Depending on regional requirements, Powerwall can be installed either through conduit orthrough a cable gland. Follow local codes to determine which is appropriate. The conduit plate hole has a 28.2 mm (1.11 in) diameter. It supports ¾” trade flttings, and PG-21 andM25 glands. The conduit plate has passed water ingress testing with individual cables squeezed together in a single gland. All flttings other than the conduit plate itself are provided by the installer. The access point on Powerwall is centered on the bottom of the device. 1. Use a T30 Torx driver to remove the conduit plate. 2. For conduit conflgurations, feed the wires through the conduit and conduit opening. Makesure that wires are not frayed. 3. For cable gland conflgurations, push out the protective coverings and feed the wires through the gland. Make sure that wires are not frayed. 4. Tighten the gland or conduit opening to the housing plate. 5. If the conduit plate was removed, reattach it to Powerwall and torque to 7 Nm (62 in-lbs). 6. Route the cables along the same path as the internal wiring harness (toward the front of Powerwall), then down to reach their destinations as shown in the circuit board image. Theplastic cover over the board has raised printing on it that names each terminal. Step-by-Step Installation Instructions 24 Powerwall Installation and User's Manual STEP 14 - CONNECT MULTIPLE POWERWALLS TOGETHER If the site is installing multiple Powerwalls, follow these instructions for wiring the units. If not, skipto the next step. Note: Ensure that the multi-Powerwall installation meets local requirements for DC disconnectsand correctly rated overcurrent protection. Note: Always check with the inverter partner for inverter abilities and instructions beforeconnecting multiple Powerwalls. 1. Remove the splash cover as described above. 2. Connect the wiring coming from the inverter (communications +/-, enable line, and 12V Logic +/- wires) to the J7 connector as the primary connector. 3. Connect the output communications, enable, and 12V logic wiring going toward the nextPowerwall to the J6 connector. 4. Run 12V thermal power independently to each Powerwall. Depending on the 12V power capability of the inverter, and the use case (running two Powerwalls simultaneously vs. in series), it may be necessary to add additional 12V power supplies. If the inverter’s 12V power supply can support multiple Powerwalls, it is possible to splice multiple 12V runs together. Caution: Do not splice 12V wiring inside Powerwall. 5. Run high voltage wiring independently to each Powerwall. 6. Reinstall the splash cover. STEP 15 - CONNECT POWERWALL TO THE INVERTER Run the wires between Powerwall and the inverter as described in the inverter manual. Follow local electrical installation codes for wire installation. Note: Ensure that the installation meets local requirements for DC disconnects and correctly rated overcurrent protection.

Line up the bottom cover with the bottom of Powerwall, between the side covers. 2. Tuck the back edge of the bottom cover (closest to the wall) under the metal edge of the Powerwall body. 3. Route the wires to run from the conduit plate or gland back (toward the wall) below theground lug, then forward again to match the internal wiring harness path under the splash cover into the circuit board. Verify that the wires are not pinched or kinked by the internaledge of the bottom cover. 4. Close the bottom cover carefully over the wiring. Verify that the edge of the bottom cover is tucked completely under the lip of the front cover. 5. Use a 10 mm hex socket to attach the bottom cover with an M6 screw on each side. Torque to 3 Nm (27 in-lbs). 6. Once installation is complete, gently peel the protective sticker from Powerwall's front cover. STEP 18 - REPACK THE SHIPPING BOX All Powerwall packing material is recyclable. To facilitate this process, place the packing materials into the shipping box in reverse order and return the shipping box to the Tesla Energy Authorized Reseller, or recycle onsite as appropriate. Step-by-Step Installation Instructions Step-by-Step Installation Instructions 27 NORMAL OPERATION During normal operation, Powerwall is completely controlled by the inverter. If Powerwall and theinverter are installed correctly, the inverter can turn on Powerwall, begin communications, then begin to process power commands. See the inverter manual for further conflguration instructions. 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 inverter. Caution: Do not lean on, stack anything on top of, or hang anything from Powerwall or the conduit. UNINTENDED OPERATION Powerwall is not user serviceable and must be repaired by a Tesla Energy Certifled Installer who has been trained by Tesla. If any problems arise, refer to Troubleshooting on page 29 beforecontacting the Tesla Energy Authorized Reseller who sold the Powerwall unit. POWERWALL CARE Keep the top edge of Powerwall clear of leaves and other debris if installed outside, to maintain optimal airfiow. To clean Powerwall, use a soft, lint-free cloth. The cloth can be dampened with only water if needed. It should not be dripping. Caution: Do not use cleaning solvents to clean Powerwall. Operation and Care 28 Powerwall Installation and User's Manual If Powerwall is not working correctly, perform the following steps. If the issue persists, contact theTesla Energy Authorized Reseller who originally sold the Powerwall. • If Powerwall refuses to operate: check the temperature in the room and increase ventilation ifneeded. • If the inverter and Powerwall are both unresponsive: switch off the breaker for the inverter, wait for at least one minute, and then turn it back on. • If a brownout or blackout is experienced during backup: reduce the loads and check the breakers. • If it is not possible to communicate with the inverter through its portal: ensure that the homeInternet connection is working. • Check the inverter manual to learn about diagnosing Powerwall. • Follow the troubleshooting steps outlined in the inverter manual. Troubleshooting Troubleshooting 29 In the event of any threat to health or safety, always begin with these two steps: 1. Immediately contact the flre department or other relevant emergency response team. 2. Notify all people who might be affected and ensure that they are able to evacuate the area. Then, and only if it is safe to do so, attempt to address the other suggestions below. • In case of a flre: • If it is safe to do so (and a disconnect exists), switch off the DC disconnect on the inverter. • If it is safe to do so, switch off the AC breaker to the inverter. • Acceptable flre extinguisher types are water, CO2, and ABC. Avoid type D (fiammable metal) extinguishers. • In case of fiooding: • Stay out of the water if any part of the battery, inverter, or wiring is submerged. • If it is safe to do so (and a disconnect exists), switch off the DC disconnect on the inverter. • If it is safe to do so, switch off the AC breaker to the inverter. • If possible and safe to do so, protect the system by flnding and stopping the source of the water, and pumping water away. • Let the area dry completely before use. • If there is an unusual smell or smoke: • If it is safe to do so (and a disconnect exists), switch off the DC disconnect on the inverter. • If it is safe to do so, switch off the AC breaker to the inverter. • Ensure nothing is in contact with Powerwall. • Ventilate the room. • Contact the Tesla Energy Authorized Reseller who sold the Powerwall. • If Powerwall is leaking coolant: Warning: According to the U.S. Environmental Protection Agency, coolant can be absorbed through the skin and cause damage to internal organs. Ensure that it does not touch or enter any part of the body including, but not limited to, skin, eyes, and mouth. • If it is safe to do so (and a disconnect exists), switch off the DC disconnect on the inverter. • If it is safe to do so, switch off the AC breaker to the inverter. • Ventilate the area. • Contact the Tesla Energy Authorized Reseller who sold the Powerwall. When cleaning up spilled coolant: • Wear safety goggles, rubber gloves, pants, a long sleeved shirt, and fully closed shoes. • Avoid further coolant spill by putting a bucket under the leak. Powerwall holds up to 1.6 L(1.69 qt) of coolant. • Pour cat litter, sawdust, or another absorbent material on the spill immediately. Allow the material to absorb as much of the coolant as possible. • Use paper towels to collect the material that was used and discard the soiled paper towels in a sealed plastic bag. Place the sealed plastic bag into the garbage. • Clean up anything that remains using soap and warm water. • If Powerwall is making unusual noises: • If it is safe to do so (and a disconnect exists), switch off the DC disconnect on the inverter. • If it is safe to do so, switch off the AC breaker to the inverter. • Ensure that nothing is in the vent on top of Powerwall or in the fan. • If nothing was found, contact the Tesla Energy Authorized Reseller who sold thePowerwall.
