However,.for best performance Tesla recommends installing Powerwall in locations-with ambient temperature between 32°F to 86°F (0°C to 30°C) year round. When outside this optimum temperature range, charge/discharge power may be reduced and Powerwall will utilize its thermal control system more frequently to maintain battery cell temperature which will reduce the energy efficiency of the system. Systems operating off-grid for long periods (>4 hours) in cold weather may need to curtail PV, and reduce energy used for pre-conditioning. • For cold climates Tesla strongly recommends installing Powerwall indoors when possible (particularly when long outages are expected). • For hot climates Tesla recommends keeping Powerwall out of direct sunlight. Installation in full sun raises the temperature inside the enclosure above ambient temperature. This temperature rise is not a safety risk, but may impact battery performance. Additionally, if stored in a cold environment (e.g. below 0°C) before installation, it may take several hours for Powerwall to raise its internal temperature using pre-conditioning..Tesia recommends storing Powerwalls in a warm location prior to installation to help efficiently commission and test the system. - Powerwall 2 AC Installation Manual 11 PREPARING FOR INSTALLATION In the Powerwall Box I T 9 L 1 I ' I a i In the Powerwall Accessory Bag - Powerwall Accessory Bag: Tesla P/N 1104517-00-x --i'l-=t'm i 0 0 0 1 2 3 4 5��� Wiring compartment (1) AC power (3) Wago 2- (1) 4-pin terminal (1) 4-pin terminal cover with (4) screws harness position lever nuts block connector block,connector with 120-Ohm terminating resistor 6 7 8 9 (1) 32-mm reducing (2) 25-mm (1) 35-mm rubber (1) drillable washer reducing grommet threaded cable washers gland Powerwall 2 AC Installation Manual 12 PREPARING FOR INSTALLATION In the Backup Gateway 2 Box T S L n V N 5 In the Backup Gateway 2 Accessory Bag I ' 0, .�. . . i iSCONNECT iMAIN + ISCONNECT 6— cr - G01N[kM'Atl2AC -CIL i-, 1 2 3 (1) Main circuit breaker adhesive label (1) Tesla 100 A CT (4) Sealing washers 4 ; 5 (1) Tesla CT extension cable harness [10 ft/3 m] (1) Owner's Guide ^� Powerwall 2 AC Installation Manual 13 PREPARING FOR INSTALLATION Required Tools • Personal protective equipment (safety glasses, gloves, protective footwear) • Drill and drill bit for drilling pilot holes in mounting surface • Torque screwdriver with 1/4-inch bit holder and Torx T20 bit • Large (5 mm) flathead driver bit (for Powerwall Earth terminal) • Small (2 mm) flathead screwdriver(for wiring connector spring terminals) • Torque wrench with 1/4-, 3/8-, and 5/16-inch Allen bit (for Backup Gateway power connections) i • Socket wrench with 8 mm hex socket • Wire strippers/cutters for 24 AWG to 250 kcmil (0.2 mm2 to 120 mm2) wires • Installation tools (level, stud.sensor, tape measure, pencil, painter's tape, flashlight) • Multimeter and Loop Impedance Tester • Lift equipment capable of lifting and supporting 125 kg up to 1.5 m • Ratcheting strap to secure Powerwall to lift equipment • Digital camera or smartphone for documenting the installation A WARNING: Powerwall is heavy.

An energy meter accomplishes this by measuring voltage'(by voltage tap) and current (by Current Transformer, CT) at certain points in the system. There are many possible configurations for installing metering depending on system design. However, there are two goals: • Metering the Site- Site meters show the overall power flow to/from a site from the Grid's perspective. Thus, Site meter(s) must be installed upstream of all solar production, Powerwalls, and loads. Multiple physical Site meters can be installed together where needed, but their sum should capture all of the power flows from load, solar, and Powerwall(s). • Metering all Solar- Solar meters capture-production from PV inverter(s). There must not be any loads or Powerwalls behind the Solar CTs. This would result in under- or over-estimation of solar production. Site and Solar Metering for Backup Gateway 2 Backup Gateway 2 makes metering simple with built-in options for Site and Solar metering: • Internal Primary Meter(Meter X) - This Site meter may be used when the Grid connection is at the Supply terminals. No additional steps are needed during install. If there are any loads or solar upstream of the Supply terminals, a Remote Meter must be used to meter the Grid connection point. • Internal Auxiliary Meter (Meter Y) - Metering solar circuits inside the Gateway or in adjacent switchboards is simple with the three (3) internal CT connections for use with Tesla 100 A CTs (one included in the Accessory Kit). Additional Tesla 100 A CTs (Testa P/N 1467316-00-x) may be ordered individually. The Tesla 100 A CTs may be extended a max distance of 330 ft (100 m) by splicing twisted pair or using the Tesla 100A CT Extension (10 ft/3 m) (Tesla P/N 1467274-00-x). Use 20 AWG (0.5 mm2) conductors or larger to extend CTs up to 330 ft (100 m). Voltage rating of the extension wire must be equal to or greater than all other adjacent circuits. Depending on site layout it may not be possible to use internal Gateway 2 meters, and Remote Energy Meters will be required. • See Appendix D: Configure Energy Metering on page 56 for further guidance-on metering. • See Appendix E.-Installing a Neurio Energy Meter on page 57 for Remote Neurio Meter installation instructions. Powerwall 2 AC Installation Manual '34 1 - STEP 6: INSTALL ENERGY METERING FOR THE SYSTEM Install Tesla 100 A CTs J A WARNING: Before installing, disconnecting, and/or adjusting CTs, ensure the circuits being measured are not energized and the system is completely powered down. Failure to de-energize the system may compromise operator and equipment safety. 1. Plug the Tesla 100 A CT into the terminal in the Backup Gateway.

The CT3 terminal has a default voltage reference to Ll but can be configured as L2 in the Commissioning Wizard. • Ensure CTs are facing the proper direction as indicated on the label. A CT will show negative current if installed backwards. • When upgrading a Gateway 1 system, the existing Remote(Neurio) Energy Meter(s) may be left in place and re-paired with the new Gateway. The Remote Meter must be power cycled within one minute prior to re-pairing. If metering Site power with the Remote Meter, ensure the Backup Gateway 2 internal site meter is de-selected in Commissioning. • See Appendix G.Installation Troubleshooting on page 65,for CT configuration troubleshooting tips. • The Powerwall installer has the option to set a Conductor Export Limit, or a Site Charge Limit. When used, the Powerwall will dynamically curtail to meet these site-specific programmed thresholds. See Appendix F.- Feature Notes on page 63 for more information. Powerwall 2 AC Installation Manual 35 STEP 7: COMPLETE THE INSTALLATION Plan Internet Connection for the Backup Gateway 2 Internet connectivity is required to receive the full 10-year Powerwall warranty, and for the customer to see their system in the Tesla App. For best performance, ensure Ethernet and Wi-Fi connections are both configured during commissioning. The Gateway will automatically select the network option with best connection. I Cellular is available only as a backup connection when Wi-Fi and Ethernet connections are lost. Cellular should not be relied•on as the default connection method. Install Ethernet Connection • Ethernet cable must be CAT5 (24 AWG) cable at minimum. • If not possible to run an Ethernet cable directly to the customer's network router, Powerline Ethernet socket adapters may be used. • See Appendix B: Wiring Reference on page 45 for the position of the Ethernet port. Close the Wiring Compartments and Turn the System On 1. Before closing any installed hardware, take photos of the completed wiring in the Powerwall, Backup Gateway, and main distribution board. 2. Ensure that all conduit junctions and cable entry points are secure and properly sealed. 3. Arrange the communication and AC power wires neatly inside the Powerwall wiring compartment. 4.

The Neurio Energy Meter(s) connect to Backup Gateway 2 by wireless connection, or wired communication between the meter and the Backup Gateway using an optional 2-conductor RS485 meter communication harness (Testa P/N 1133339-00-x). The Backup Gateway can support wired communication for up to two meters. NOTE: When upgrading a Gateway 1 system with Gateway 2, the existing Neurio Energy.Meter(s) may be left in place in.the main distribution board and re-paired. The Neurio Meter must be power cycled within one minute prior to re-pairing. If metering,Site power with the Neurio Meter, ensure the Gateway 2's internal site meter is deselected in Commissioning. Wireless Communication to the Backup Gateway The Neurio Energy Meter (Testa P/N 1112484-00-x) may be wirelessly paired with Backup Gateway as part of the normal Powerwall commissioning process within the Commissioning Wizard. Wired Communication to the Backup Gateway As an alternative to wireless communication, it is possible to establish wired communication between the meter and the Gateway using an optional 2-conductor meter communication harness (Testa P/N 1133339-00- x). Up to two meters can be wired directly to the Gateway. If the meter is located outside the Gateway, the harness leads can be extended by splicing additional wire to the harness. See Maximum CT Extension on page 17. The meter antenna is always required, even if the-meter is located inside the Backup Gateway enclosure or connected to the Gateway using the optional wired communication harness. NOTE: Tesla recommends connecting the meter via wireless Wi-Fi rather than using a wired connection. This is because the meter receives firmware updates with new features and improvements, but only if the meter is communicating to the Gateway via Wi-Fi. Firmware updates are not possible when the meter is using wired communication. If you must_use wired communication, connect the meter to the gateway wirelessly first to update the meter firmware, then transition to wired communication. 1. Plug the 2-conductor harness into the port on the top of the meter. 2.

Figure 26. Voltage Line Harness with Combined Leads Current Transformer Placement CT placement locations include the following: Site(Grid): A CT is placed between the utility meter and main switch to measure both load and generation. See Appendix F for information on implementing a Site Limit to curtail Powerwall charging from the grid. Solar: If the site includes solar equipment, a CT is placed after the solar inverter to measure the solar output. Load: Site and solar metering are preferred. However, in configurations where it is not possible to locate CTs between the utility meter and the main switch, load metering can substitute for site metering. Conductor: Where desired to curtail Powerwall discharge on a conductor, a dedicated Conductor Limit CT can be installed. This feature is optional for installations. See Appendix F. Feature Notes on page 63 for more information. See Appendix C on page 49 for system wiring diagrams depicting CT placement for various wiring configurations.

When the meter is relocated into the main distribution board, use the antenna extension to place the antenna on the outside of the distribution'board. Current Transformer Orientation CTs must be installed with the label on the CT housing pointing toward the power source, according to the following table and diagram. Always verify CTs are in the correct orientation by observing power flow in the Commissioning Wizard. Figure 28.

If the wiring configuration allows, it is possible to pass multiple conductors of the same type through a single CT, provided the sum of the conductor's current ratings does not exceed the CT current handling capacity. This is especially useful for systems with multiple solar inverters. NOTE: Multiple conductors through a single CT is only possible if all conductors are on the same phase. i l Powerwall 2 AC Installation Manual 60 c APPENDIX E: INSTALLING A NEURIO ENERGY METER Figure 29. Multiple Conductors Passing Through Single CTs 00 Ma e e e e 1 e If a site has multiple solar inverters spaced far apart, or if a main panel has two main breakers (for example, 400 A service with two 200 A breakers), a Y-splitter cable(Testa P/N 1129625-00-x) can be used to connect two CTs on the same phase to a single meter port. Figure 30.Y Cables Connecting CTs on the Same Phase e e e e 1 800 A CTs are also available for larger service sizes (Tesla P/N 1447689-00-x). The 800 A CTs can be used with the standard Neurio Energy meter, but the 800 A CT option must be selected in the Commissioning Wizard drop down menu on the CT page. If using a Y splitter with 800 A CTs, total current should not exceed 800 A. Powerwall 2 AC Installation Manual 61 APPENDIX E: INSTALLING A NEURIO ENERGY METER Metering Split-phase Solar with a Single CT Metering a split-phase solar inverter with one Current Transformer(CT) is supported with firmware version 1.37 and later. In this configuration, connecting a single CT to one of the two PV inverter output phases allows total power output to be calculated by software. The single CT must be installed on the phase that corresponds to the same CT port on the meter (phase A or B). It is possible to meter multiple split-phase solar inverters with one CT, if the solar inverter circuits are physically near each other: 1 1. Install both solar inverters with the same phasing 2. Group all conductors of the same phase together to pass through a single CT i 3. As with a single inverter, it is important that the phase of this CT matches the phase of the voltage reference on the meter Installing the Meter Using the self-drilling screws provided in-the meter kit, attach the meter to the inside of the main distribution board or to another surface. Choose a location that takes into account the voltage line harness and CT cable lengths. To wire the voltage taps: 1. Plug the voltage line harness into the meter in its new location. 2. Connect-, he voltage line harness leads to a dedicated circuit breaker (not exceeding 16 A) of corresponding phase inside the distribution board: Voltage Harness Port/Wire Color Distribution Board Connection A/ Black Ll breaker terminal B/Red L2 breaker terminal C/Blue L3 breaker terminal or spliced with the Red B wire N/White` Neutral bus bar To locate the CTs: • Place a CT on the corresponding power wire in the main distribution board, after the utility meter and ahead of any loads. • If the site includes solar equipment, place an additional CT on the solar wire in the main distribution board. l Powerwall 2 AC Installation Manual 62 APPENDIX F: FEATURE NOTES Configuring Site Limits The Backup Gateway can be configured to limit Powerwall charge power from the grid. When Site Limits are programmed by the installer during commissioning, the Powerwall charge power is dynamically adjusted based on the net measured site power and the programmed site limit threshold. 1 Site Limits are configured in the Commissioning Wizard; select Site Import Limit from the Settings page. At the conclusion of the commissioning process, a summary of the settings will be displayed. The net site power measurement can be a virtual aggregated meter; therefore, abide by all prior guidance on meters and CTs. ` Configuring Conductor Export Limits Overview J The Powerwall system can be configured to limit Powerwall discharge power. When Conductor Export Limits are programmed, the Powerwall discharge power is dynamically adjusted based on the amperage measured by designated current transformers (CTs) and the programmed Conductor Limit amperage threshold. Set Conductor Export Limits Install CTs _ • Conductor CTs must be installed on conductors that are: o Between the grid connection and the Powerwalls. • At a location where the Powerwalls have control over current. • CTs should\be oriented such that the label faces toward the grid. Complete Commissioning 1. In the Commissioning Wizard, assign the correct CTs to Conductor. NOTE: CTs can only be assigned one designation, meaning a CT cannot be both a Site and a Conductor CT. _ 2. Enter the amperage for the Conductor Limit on the Settings page. At the conclusion of the commissioning process, a summary of the settings will be displayed. Load Shedding Overview The Backup Gateway allows for load shedding, meaning a low voltage control circuit can be wired to control a specific load. For instance, an air conditioning load controlled by a thermostat can be wired to the low voltage control circuit in the Backup Gateway,so that the load can be shed when Powerwall is off-grid. .When commissioned for load shedding and the Powerwall system is on-grid, the low voltage control circuit is closed and the load is powered. When commissioned for load shedding and the system is operating off- grid, the low voltage control circuit is open and the load is OFF. Powerwall 2 AC Installation Manual 63 APPENDIX F: FEATURE NOTES When the system is wired for load shedding, the controlled load breaker can remain on the backup loads panel.

Kl .Powerwall 2 AC Installation Manual 67 APPENDIX H: MULTI-POWERWALL INSTALLATIONS� Electrical Equipment Sizing and Overcurrent-Protection; Overview This section describes the requirements for installation of multiple Powerwall units with a Backup Gateway in North America. l Pre-Requisites for Design Before designing a Powerwall system with more than four Powerwall units: • AC line impedance must be measured at the installation site to ensure the utility grid connection is able to support the desired quantity of Powerwalls. If the required grid impedance is too high, the Powerwalls may not connect to the grid, resulting in undesirable operation. See Table 1 in this app note for required minimum impedance values. • Minimize Impedance: o Install the Powerwalls as close as possible to the point of interconnection with the grid. The recommended maximum wire length is 33 ft (10 m). o Install wires larger than required by code between the Powerwall generation panel and the point of interconnection with the grid. Example, if the design requires 3/0 AWG wire, use 4/0 AWG wire. • Tesla Certified Installers should submit their multiple Powerwall system designs and measured impedance values to Tesla for review by sending design documents to powerwalldesignreview@tesla.com. Copy your Tesla account manager on all submissions. • Designers must properly size overcurrent protection and loads to account for the full power potential of multiple Powerwalls. For example, a 10-Powerwall system is capable of discharging up to 50 kW of power. See design examples in Panel Configuration and Breaker Sizing. • Multi-Powerwall installations may require larger Powerwall communication wire between the Backup Gateway and the Powerwall units. Please refer to the Powerwall 2 AC/Gateway Communication Wiring application note on communication cable requirements, as your install may require up to #16 AWG or 1.3 mm2 wire. • For systems between 11 to 20 Powerwalls, multiple Backup Gateways are required, as each Gateway can only control up to 10 Powerwall units. Please refer to the Multiple Gateways on a Single Site application note on the Partner Portal. • Grid impedance does not need to be measured for off-grid systems as there is no grid impedance to measure. Pre-Requisites for Installation Before installing and commissioning a multi-Powerwall system: • Plan for the commissioning process to take longer than a typical installation. It can take up to 3 minutes to complete the commissioning scan and verify process for each Powerwall, so a 10-Powerwall system can take up to 45 minutes during this stage of commissioning. NOTE: Do not interrupt a commissioning step, turn off the system, or unplug the communication wiring at any time during the,commissioning process. J Powerwall 2 AC Installation Manual 68 APPENDIX H: MULTI-POWERWALL INSTALLATIONS Service Type and Capacity Requirements The Backup Gateway supports systems of up to 10 Powerwall units, but the maximum number of Powerwalls may be limited by the site electrical service, utility grid infrastructure, or local requirements; therefore an impedance test is required to confirm. . Line Impedance Requirements The sensitivity of the system to line impedance increases with the number of Powerwalls in the system. (See Impedance Requirements for Multi-Powerwa//Systems on page 70 for the maximum allowable impedance as it relates to number of Powerwalls.) If grid impedance at a site exceeds the maximum allowable value, do either of the following: J • Decrease the impedance of the site grid connection. This may require coordinating with-the local electrical utility. See "Minimize Impedance" in the Pre-Requisites for Design for suggestions. • Reduce the quantity of Powerwalls installed at the site to meet the maximum allowable impedance value. If impedance values exceed the requirement for the installed number of Powerwalls, the system may not function properly. Measuring Line Impedance To.determine the line impedance at a site, measure between Line and Neutral where the Powerwalls will be interconnected to the site electrical system with testing equipment such as the following: • Fluke,1660 Series Installation Tester (1662, 1663, or 1664) • Metrel-M13000 Multifunction Tester • Megger LTW315 Loop Impedance Tester Example Line Impedance Test Instructions For details on line impedance testing, refer to the test equipment manufacturer's instructions. The steps below are.general guidelines only. WARNING: Impedance tests must be performed on an energized electrical system. Impedance tests should be carried out only by trained electricians using appropriate safety equipment and safety practices. 1. Follow manufacturer instructions to calibrate and zero the impedance tester before taking measurements. 2. Complete the test on Ll first, then move to L2. 3. Connect all three voltage test leads - Line, Neutral, and Ground 4. Follow manufacturer instructions to verify that the correct voltage is present. Switch the tester to a voltage measurement mode and check Line-to-Neutral and Line-to-Ground voltages. 5. Follow manufacturer instructions and take an impedance measurement where the Powerwalls will be interconnected to the site electrical system. Switch the tester to the appropriate impedance measurement mode and take the following readings: o Line-Neutral o Line-Ground NOTE: The Line-Neutral impedance measurement is the value referenced in Impedance Requirements for Multi-Powerwall Systems on page 70.

In systems with 7 or more Powerwall units, to ensure sufficient ampacity while keeping total charge/discharge current within the 200 A capacity of the Backup Gateway, a separate generation panel (400 A minimum) with a 200 A main breaker is recommended. The example below shows the following: • 400 A main panel with a 200 A main breaker in the panel or in the Backup Gateway • 400 A generation panel with 200 A main breaker • Load panel w/200 A main breaker Example 400 A Service with Separate Generation and Load Panels 11 400 A Service 0 12 200 A Breaker in Backup Gateway ~ 3 200 A Breaker (max) in-200 A Panel Q 4 Loads © 5 200 A Breaker (max) in 400 A Panel 6 Solar 7 7 or more Powerwalls f © © i 0 When wiring the load panel, ensure that combined loads do not exceed main breaker continuous or peak current ratings, whether the system is on-grid or off-grid.

Connect each AC Powerwall to the main or sub electrical panel of the installation (depending on the system configuration) according to the electrical service type. 3. On the Powerwall side, strip the ends of the wires and attach them to the corresponding leads on the 3- pin AC power harness. 4. Plug the AC power harness into the AC connector in the Powerwall wiring compartment. Ensure that the connector clicks into place. NOTE: Each Powerwall connection to the main electrical panel requires an independent 30 A circuit breaker. This breaker serves as the disconnect for the Powerwall, and must be wired in accordance with local wiring codes and regulations. 5. Reconnect the power and communications leads that were disconnected from the first Powerwall at the beginning of the installation'. 1 Step 6; Close the Wiring Compartments and Replace the Covers 1. Arrange the communication and AC power wires inside the Powerwall wiring compartments. 2. Ensure that all conduit junctions and cable entry points are secure and properly sealed. 3. Replace the wiring compartment cover on each Powerwall. Ensure that the cover seats properly on the gasket so that the compartment is sealed. Tighten the fasteners using a Torx T20 bit: Torque to 1.5 Nm. 4. Replace each of the side covers on the Powerwalls by pushing the top.into place and working toward' the bottom to reattach it to the clips along the length of the unit.
