To secure the full 10-year warranty for Powerwall, it must be reliably connected to the Internet to allow remote firmware upgrades from Tesla. If an Internet connection is not established or is interrupted for an extended period, and Tesla is unable to contact the owner, the warranty may be limited to 4 years. To ensure that the owner can receive the full 10-year warranty, be sure to complete the commissioning process so that registration information is sent to Tesla. For more information, refer to the Powerwall Warranty for your region at www.tesla.com. Powerwall 2 AC Installation Manual 8 T SITE REQUIREMENTS AND PRE-INSTALLATION GUIDANCE Powerwall and Backup Gateway 2 Installation Requirements Powerwall comes with a separate Backup Gateway to enable integration with the electrical grid and generation like solar systems (refer to Compatibility Matrix for information on what can be connected with Powerwall). The Backup Gateway communicates with the system by means of wireless and wired connections. Wiring and conduit (where required) must be provided by the installer and installed to comply with local codes. AC isolation and interconnection requirements between the Powerwall system and the electrical panel are subject to local codes. Ensure that the installation meets local isolation and interconnection requirements. 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. A WARNING: All Powerwalls in the system must be installed on the 'Backup' side of the Backup Gateway's relay. AWARNING: When Powerwall is installed in a dwelling unit, fire detection and protection equipment should be installed in accordance with local building and fire codes. A WARNING: Do not connect the Backup Gateway in any way that bypasses or short-circuits its relay. A WARNING: Do not connect the Backup Gateway to the source side only or to the load side only. The Backup Gateway must have both source and load connections, and must be wired in compliance with local codes. ACAUTION: The Backup Gateway 2 is rated for 10 kA maximum supply fault current. Where local regulation requires a 10 kA rating, all breakers employed in circuit with the Backup Gateway 2 should also be rated to 10 kA. 1 CAUTION: The Manual Override switch inside of the product must not be used to simulate a grid outage or take home off-grid. A main isolation switch should be installed upstream of the Backup Gateway for testing the system and for service purposes. ACAUTION: Before installing, disconnecting, and/or adjusting current transformers for metering, 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. NOTE: All installations must conform to the laws, regulations, codes, and standards applicable in the jurisdiction of installation. The Backup Gateway must be wall-mounted and can be configured for cable entry at the top, bottom, rear, or sides of the enclosure. It requires adequate clearance for installation and cabling or conduit. Wiring and conduit (where required) must be provided by the installer and the installation must comply with local codes and UL514B requirements.

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. Tesla recommends storing Powerwalls in a warm location prior to installation to help efficiently commission and test the system.

Make sure the area is isolated from hazards that could damage Powerwall, such as vehicle traffic or flooding. Consider the spacing requirements for Powerwall (see Appendix A:Powerwall Mounting Details on page 41). Choose Powerwall Cable Entry Determine whether cables will be routed into Powerwall from the side or the back of the unit. • For side cable entry, a conduit fitting or cable gland must be used to seal the entry into the wiring compartment. • For back cable entry, a rubber grommet or cable gland is used to seal the entry into the wiring compartment. NOTE: If Powerwall is mounted on a wall with studs spaced 24 inches apart, cable entry from the back of Powerwall may be blocked. Choose Backup Gateway Cable Entry Determine whether cables will be routed into the Backup Gateway from the top, bottom, sides, or rear of the enclosure. NOTE: For cable entry at the top of the Backup Gateway enclosure, a Tesla Top Hub must be used in order to maintain enclosure ingress protection. Plan the Electrical Service Connection to Backup Gateway The Backup Gateway is service entrance rated. When installed at the service entrance, appropriate overcurrent protection must be installed in the Backup Gateway. The Backup Gateway can accommodate a main circuit breaker between 100 and 200 A. Breaker sizing and installation must comply with the National Electric Code. Plan Amount and Size of Conduit or Raceway Calculate the amount and size of conduit or raceway needed for the installation, based on fill limits and local code requirements. An adapter may be required between the entry into the Powerwall wiring compartment and the conduit.

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/fro.m 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 (Tesla 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 STEP 6: INSTALL ENERGY METERING FOR THE SYSTEM Install Tesla 100 A CTs AWARNING: 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. Ensure the connector is fully seated in the terminal. 2. Clamp the CT around the conductor to be measured. Figure 16. Embedded Site CTs and Solar CT Connectors 0 0 o Elm o- m m o 0 41 po o ® o ® o ,� w �a r-1 _ rani 4• Tips • See Appendix D: Configure Energy Metering on page 56 for additional diagrams on configuring energy metering. • When metering split-phase 240 V solar inverters, a single CT on L1 or L2 can be used to meter production. • The CTl and CT2 terminals have voltage references to Ll and L2 respectively and cannot be reconfigured. The CT3 terminal has a default voltage reference to L1 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 T 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. 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. Replace the cover on the Powerwall wiring compartment. Ensure that the cover seats properly on the - gasket so that the compartment is sealed. Using a Torx T20 bit, tighten the fasteners to 1.5 Nm. S. Replace the left side cover on Powerwall by pushing the top into place and working toward the bottom to reattach it to the clips along the length of the unit.

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 (Tesla 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 (Tesla 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. Connect the harness leads to the Backup Gateway Meter Communication ports by inserting them into the corresponding connector, according to the following table and diagram.

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. Voltage Tap and Current Transformer Connections Voltage taps and current transformers must be connected so they are measuring the same phase. They must correspond according to the following table and diagram: Figure 27.Voltage Tap Port (left) and Four CT Ports (right) on Bottom of Meter A B 0 (D Q LNLl C A B C A Phase Meter Voltage Tap Port Meter CT Port ' Site Ll A ! 1/A � Site L2 B/C---_.__ ---------__ __-- --;--___-------_------------ -------_—_ _� Solar Ll �------- ------- - -- 4/A Solar L2 I 3/C *With combined leads in voltage line harness, ports B and C are equivalent (correspond to L2). Powerwall 2 AC Installation Manual 59 APPENDIX E: INSTALLING A NEURIO ENERGY METER Meter Placement and CT Wire Lengths CT leads are 1.5 m long and can be extended to a maximum length of 50 ft (15 m), as follows: • For a total extended length of up to 15 ft (4.5 m): CT wiring can be extended with up to one Neurio CT Extension (10 ft/3 m) (Tesla P/N 1125547-03-x) • For a total extended length of up to 50 ft (15 m): CT wiring can be extended by using wire with the following properties: o Shielded, twisted pair with drain wire o Wire gauge of 24-18 AWG (0.2-1.5 mm2) o Voltage rating equal to or greater than all other circuits in shared enclosures or raceways • If the distance between the meter and the CT is greater than 50 ft (15 m), the meter can be relocated, or a second meter can be used. 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. CT Orientation in Relation to Power Flow 0 CT Usage CT Orientation Site CTs I CT label facing toward the service entrance/grid Solar CTs CT label facing toward the solar inverter Load CTs CT label facing away from the loads Current Transformer Capacity Standard Neurio CTs have a capacity of 200 A. 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. Powerwall 2 AC Installation Manual 60 APPENDIX E: INSTALLING A NEURIO ENERGY METER Figure 29. Multiple Conductors Passing Through Single CTs 6 e e e e 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 Jel Ie 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. NOTE: When 200 A CTs are used in parallel, each CT can measure current on an input channel up to 400 A. When 800 A CTs are used in parallel, each CT can measure current on an input channel up to 1100 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. Install both solar inverters with the same phasing 2. Group all conductors of the same phase together to pass through a single CT 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 the 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 i L7 breaker terminal j 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. Powerwall 2 AC Installation Manual 62 T 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. 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 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. o 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. Powerwall 2 AC Installation Manual 63 APPENDIX F: FEATURE NOTES 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. When the system is wired for load shedding, the controlled load breaker can remain on the backup loads panel.

Permanently off-grid systems use the Backup Gateway Aux terminals for generator control rather than for load shedding. NOTE: To activate this feature in the Commissioning Wizard, check the Open Relay when Off-Grid box under "Gateway Low Voltage Relay" on the Installation page. This feature can be activated in firmware version 1.47 or later. NOTE: See the Load Shedding with the Backup Gateway application note for an example installation which uses the load shedding feature to control a condenser for a central air conditioning system.

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: • 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). • 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@tesia.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. 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-Powerwall 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: • 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. AWARNING: 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 Powerwall 2 AC Installation Manual 69 T APPENDIX H: MULTI-POWERWALL INSTALLATIONS NOTE: The Line-Neutral impedance measurement is the value referenced in Impedance Requirements for Multi-Powerwall Systems on page 70. 6. Record the impedance measurements. 7. Repeat steps 3-6 for L2.

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 1 400 A Service i 2 200 A Breaker in Backup Gateway 3 200 A Breaker (max) in 200 A Panel ® 4 ' Loads 5 {200 A Breaker (max) in 400 A Panel 6 Solar 7 7 or more Powerwalls f 0 0 © 0 a 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.

Using a T20 Torx bit, remove the wiring compartment covers from the previously installed Powerwall. 0 • o Step 2: Choose a Wiring Option In multi-Powerwall systems, communication wiring is daisy-chained between Powerwall units. Power wiring is direct (home run) from each Powerwall to a dedicated circuit breaker in the electrical panel. Wiring between Powerwalls can be concealed, or run externally. Concealed Wiring For concealed wiring, a hole is drilled from the front of the first Powerwall into its wiring compartment and wires are run directly into it from the back port of the second Powerwall. To use this wiring method, proceed to Step 3, "Prepare for Concealed Wiring." External Wiring For external wiring, wires are run through conduit or raceway that spans the wiring compartment ports on the side of each Powerwall. To use this wiring method, skip to Step 4, "Join the Powerwall Units." Step 3:Prepare for Concealed Wiring 1. Disconnect all wiring from the wiring compartment of the first Powerwall. Powerwall 2 AC Installation Manual 76 APPENDIX H: MULTI-POWERWALL INSTALLATIONS 2. Locate the wiring interface cover and peel back the film to expose the adhesive on the cover gasket. With the gasket facing inward, place the cover over the interface board at the back of the wiring compartment. The cover is intended to protect the circuit board and its components from metal shavings while drilling into the wiring compartment. o 3.

Slide the side clip into the gap between the two Powerwalls so that its flanges engage the side hem of each enclosure. i F l qa o, NOTE: The Powerwall enclosure hems have cutouts that mate with tabs in the clip. Powerwall 2 AC Installation Manual 80 APPENDIX H: MULTI-POWERWALL INSTALLATIONS 0 5. Press the clip until it is flush with the sides of the Powerwalls. 6. Using the provided 6 mm Allen hex wrench, do the following: o Turn the top cam 90 degrees clockwise until it clicks into place and stops rotating. o Turn the bottom cam toward the wall (toward the first Powerwall) so that the cam indicator notch on the hex camshaft head points toward the wall, until the cam clicks into place. Powerwall 2 AC Installation Manual 81 APPENDIX H: MULTI-POWERWALL INSTALLATIONS NOTE: The top cam is symmetrical and can be rotated in either direction to secure the side clip. The bottom cam must be rotated toward the first Powerwall so that its stepped side (indicated by the notch on the hex camshaft head) engages the housing of one of the Powerwalls. 7. Repeat steps 3-6 to install a side clip on the other side of the Powerwalls. NOTE: If necessary, use a small rubber mallet or a hammer and wood block to gently tap the side clips so that they are fully seated in the hem of the Powerwall. 8. Position the top cover across the gap between the Powerwalls so that its flanges engage the tops of each side clip. The cover is held in place by the magnets on the tops of the side clips. O O 0 0 9. (Concealed wiring installations only) Tighten the insulation bushing on each side of the conduit nipple to secure the bridge between the two Powerwall wiring compartments. Powerwall 2 AC Installation Manual 82 APPENDIX H: MULTI-POWERWALL INSTALLATIONS 10. Use the provided shims to ensure that the Powerwalls are level. NOTE: When joined, the units should be level within +/- 2 degrees side-to-side and within +/- 5 degrees front-to-back. Step 5: Wire the Powerwall Units 1. Connect the communication ports of the two Powerwalls by doing the following: • Run the 4-conductor communication cable between the Powerwall wiring compartments. At the first Powerwall, cut back the drain wire; the drain wire should be terminated only at the second Powerwall. o Attach the provided Phoenix connector to one end of the cable, and attach the extra Phoenix connector that came with the Powerwall to the other end of the cable. See Appendix B: Wiring Reference on page 45 for additional wiring information. Powerwall 2 AC Installation Manual 83 APPENDIX H: MULTI-POWERWALL INSTALLATIONS • Connect the communication OUT connector of the first Powerwall to the communication IN connector of the second Powerwall. ■ To ground the drain wire: ■ Strip the end of the equipment grounding conductor and wrap the communication drain wire around the grounding conductor lead. ■ Insert the drain wire and grounding conductor lead into the second Powerwall chassis ground lug. The ground lug is identified with the following symbol:Q ■ Tighten the screw in the ground lug to 4.5 Nm (40 lb-in). NOTE: There will be a drain wire grounded in each Powerwall in the chain.
