INTRODUCTION Tesla Powerwall 2 was tested by Right Testing Lab, LLC, an ISO 17025 accredited laboratory, and witnessed by CSA Group, also ISO 17025 accredited and Nationally Recognized Testing Laboratory (NRTL). Testing was conducted in March 2021 in accordance with ANSI/CAN/UL 9540A:2019 Fourth Edition, Dated November 12, 2019 - Test Method for Evaluating Thermal Runaway Fire Propagation in Battery Energy Storage Systems. This supplemental guide is intended to aid Authorities Having Jurisdiction (AHJs) in the application of the test results to determine compliance with applicable codes. Specifically,where building and/or fire codes require large-scale fire test data to support deviations from the minimum requirements set forth in those codes. The Tesla Powerwall 2 has met the unit level performance criteria outlined in ANSI/CANWL 9540A when installed as follows: • The Powerwall must be installed in accordance with accompanying Powerwall 2 mounting bracket as detailed in the installation instructions. No additional non-combustible substrate is required. • For stacked installations,the Powerwall 2 stack kit accessory must be installed to provide adequate clearances for preventing unit to unit propagation. • Where applicable, a minimum clearance of 6"on the side(s) of the unit is required to prevent side-to-side propagation to adjacent units and walls. Page and Section numbers referenced from the test report are presented in bold type. For example, verification that the Tesla Powerwall 2 has met the performance criteria outlined in ANSI/CAN/UL 9540A can be found on pages 4 through 6 of the report.

Coolant System ElPower Electronics ; Battery Module i 7 Fig. 1 - Powerwall 2 Internal Component Layout T S L n ACPW2 1 TEST REPORT SUPPLEMENT 3 SUMMARY OF RESULTS A comprehensive summary of the test results for each installation layout and test configuration is provided beginning on page 3.This section provides important information needed to determine residential and fire code compliance where reduced minimum separation distances are permitted, and where the unit is intended to be installed on a combustible substrate. Final verification that the Tesla Powerwall 2 has met the performance criteria outlined in ANSI/CAN/UL 9540A can be found beginning on page 4 through 6 of the report. This portion of the report can be used as a checklist to aid in the verification of the unit's conformance to the performance criteria for each installation confiquration. In the unit level test it was demonstrated that: The Powerwall 2 mounting bracket provides adequate clearance from the wall surface on which it is mounted. Wall surface temperatures did not exceed 97°C (175°F) of temperature rise above ambient per Section 9.2.15. No additional substrate is needed. The Powerwall 2 stack kit provides adequate clearances to prevent unit-to-unit propagation when an internal fire condition is established in an initiating unit. The recommended clearance of 6"on the side of the Powerwall 2 unit, as specified in the installation manual, is also adequate to prevent side-to-side propagation to adjacent units. CELL AND MODULE LEVEL TESTS Pages 7 through 9 of the report provide background information and data collected during cell and module-level testing previously conducted. This data does not directly correlate to residential or fire code requirements, rather it is used to document and compare the characteristics of different cell chemistries and designs. One important value recorded is the temperature at which thermal runaway occurs. This temperature of 185.8°C is used to verify that an internal fire condition has been established during the Unit Level test. PERFORMANCE CRITERIA - CELL LEVEL Application of heat using film heater methodology did result in a thermal runaway condition, therefore module level testing was required, PERFORMANCE CRITERIA- MODULE LEVEL Application of heat using film heater methodology did result in a thermal runaway condition, and the resulting event was not contained by the module design, therefore unit level testing was required. The Powerwall is intentionally designed without a module-level enclosure. This allows vent gases to be routed in such a way that adds to the overall propagation resistance of the module, and prevents a dangerous buildup of gases that may lead to an explosion or deflagration hazard. T 5 L n ACPW2 I TEST REPORT SUPPLEMENT 4 UNIT LEVEL TEST - GENERAL Section 9 Unit Level Testing information begins on page 10 of the report. In additional to providing greater detail on the test setup and unit performance, this portion of the report can also be used as a checklist to aid in the verification of the testing laboratory's conformance to the test procedure. SAMPLE AND TEST CONFIGURATION ANSI/CAN/UL 9540A provides for several configurations: • Residential and non-residential use cases • Wall and floor mounting • Indoor and Outdoor locations The Tesla Powerwall 2 is intended to be installed in any of the configurations noted in Section 9.1, so testing is representative of each, and aligns with installation requirements established in the product installation manual. The unit level test begins with the application of heat at a specific site selected to present the greatest amount of thermal exposure to adjacent cells within the module. This application of heat must result in an internal fire condition in accordance with the module level test previously conducted. This was verified by laboratory staff using temperature data recorded during initiation of the event, compared against the cell surface temperature at thermal runaway during the cell level test. This temperature was determined to be 185.8°C. (See Section 5.1.1 and Section 9.1). Beginning with the indoor floor-mounted unit test, Section 9.2 on page 11 the report goes into more detail on each test setup and installation configuration. T = S L n ACPW2 1 TEST REPORT SUPPLEMENT S UNIT LEVEL TEST - INDOOR FLOOR MOUNTED Section 9.2 begins on page 11 by outlining conformance to the physical test layout and data captured during the test. An example test layout graphic has been reproduced from ANSI/CAN/UL 9540A on page 13 for cross reference with the actual layout represented in the 3D graphic provided.A summary of the recorded dimensions is included below for clarity, along with the corresponding dimension callouts from the table on page 14. The units in this test configuration were installed according to the installation instructions using the Tesla supplied support bracket and optional stack kit. The layout was chosen to represent a worst-case installation with the minimum recommended clearances specified in the installation instructions. Pages 11 through 17 demonstrate that the test layout,wall constructions, placement of the cheesecloth indicator and instrumentation fully conformed to the test standard methodology.

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 SITE REQUIREMENTS AND PRE-INSTALLATIONPRE-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. WARNING: All Powerwalls in the system must be installed on the 'Backup' side of the Backup Gateway's relay. WARNING: When Powerwall is installed in a dwelling unit, fire detection and protection equipment should be installed in accordance with local building and fire codes. WARNING: Do not connect the Backup Gateway in any way that bypasses or short-circuits its relay. WARNING: Do not connect the Backup Gateway to the source side only or to the load side only. The AL Backup Gateway must have both source and load connections, and must be wired in compliance with local codes. CAUTION: 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. A 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. CAUTION: 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 ULS14B requirements.

However, for best performance Tesla recommends installing Powerwall in locations with ambient temperature between 320F to 860F (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 ORC) 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.

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 (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 T a INSTALL NE Y METERBNG FOR THE SYSTEM Install Tesla 100 A CTs 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. 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 o - o 93 — _ ° i �-�i . _ o o ° - 0 ® ® ® o 0 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 CTI and CT2 terminals have voltage references to L1 and L2 respectively and cannot be reconfigured. 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 ST 7: COMPLETE THE INSTALLATON 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 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 (Tesla 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 11111111 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.

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.

Ene e EB e EH 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 (Tesla 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 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 o INSTALUNG A NEURIOMETER T 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 L1 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. 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. 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: • 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 Fo FEATURE NOTES 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. NOTE: The low voltage control circuit will be opened briefly during firmware updates and under abnormal fault conditions. NOTE: The load shed relay is rated up to 60 V (DC or AC) and 2 A.

If experiencing other issues in the Commissioning Wizard, refresh the web page. I If issues persist, reboot Gateway using RESET button. Updating Firmware CHECK INTERNET CONNECTION to verify Gateway network connection. Check for Update to verify you are on the latest firmware. Factory firmware ending in GF must be updated. Never power down or modify wiring during an update. ' During the update, the{Gateway will reboot which will cause the "TEG-xxx" Wi-Fi to disconnect. When ._..v,.. reconnected, refresh the web page. Configuring Energy Meters Conduct all CT tests with at least 1 kW of power flowing. Ensure all solar inverters are monitored with CTs. When using only 1 CT for solar, select Solar (1CT x2) on the Current Transformers screen in the Commissioning Wizard. For each CT, select the applicable function on the Current Transformers screen and perform the following i steps to ensure it is in the correct location and orientation: ' 4 • Adjust the Amps/kW slider to see what the CTs are reading. t • Verify the on-screen values for the CT against the applicable meter (such as the solar inverter meter or utility meter). • Ensure that: d o Site CTs are positive for import, negative for export. i o Solar CTs are positive when the PV array is producing power (Solar is NEVER negative during daytime). I i i Negative power flow may indicate CT is installed on the wrong phase! { • If the "toward source" CT label is correctly facing the solar inverter but power flow is negative, a voltage- current mismatch is likely. • Physically move the CT to the correct phase with the label facing the correct direction. Do not use the Flip checkbox in this case. i Powerwall 2 AC Installation Manual 65 A PEN➢ I m INSTALLATION TROUBLESHOOTING Solar CTs should only meter generation sources. It is never recommended to meter both generation and loads using the Solar (1 CT x2) option. If it is absolutely necessary to install solar and a small amount of loads together without independent metering, you must install the solar CT on the phase without any downstream loads. Use a handheld clamp or fork meter to verify CT readings. v Powerwall 2 AC Installation Manual 66 APPENDIX G: INSTALLATION TROUBLESHOOTING Reset the Backup Gateway If experiencing issues with the Backup Gateway, reboot the Gateway using the RESET button (1 below).

Powerwall 2 AC Installation Manual 67 APPEND( H: MULTI-P E L 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. 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. Powerwall 2 AC Installation Manual 68 PPEN®IX 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-PowerwaN 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. WARNING: Impedance tests must be performed on an energized electrical system. Impedance tests AL 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 L1 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. Powerwall 2 AC Installation Manual 69 APPENDIX Ha MULTI—POWERWALL INSTAL ATI NS 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 400 A Service ❑ ! 2 200 A Breaker in Backup Gatewayg 13 1200 A Breaker (max) in 200 A Panel ® t4 Loads 5 200 A Breaker (max) in 400 A Panel 6 Solar h7—t—7 or more Powerwalls f 0 i 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.
