ICH,q � `omsb I C V.VYO 'ichael K Dunn, RA E a TESLR Powerwall 2 AC & Backup Gateway: Permitting & Inspection Support for Tesla Home Energy Storage System Summary Description Powerwall 2 AC (Powerwall) and the Backup Gateway (Gateway) comprise a state-of-the-art battery system for residential and light commercial applications. Together, they enable energy stored from the grid (or renewable sources, like solar), to be used at night or to provide backup power in a grid outage. Powerwall arrives at the job site as a factory assembly that includes: Lithium-ion battery cells o Isolated DC/DC converter (to step up the battery's voltage) Integrated AC inverter (to convert low voltage DC from the battery to AC for the home or business) Liquid thermal management system (to maximize battery performance) The battery cells inside Powerwall are the components closest to a conventional battery. No one is ever exposed to these cells because they are electrically and physically isolated from contact at all times. All Powerwall installations require the Gateway, which serves severa"I functions: • Monitors the grid for outage a Instantly isolates Powerwall from the grid (during grid outage, or when providing backup.power) • Communicates with the Powerwall (via communication cables) Monitors & manages how energy is used (including self-consumption, load-shifting & backup) Functions as both service entrance and disconnect(when installed with a breaker) When a grid outage is detected, the Gateway instantly isolates Powerwall from the grid using a microprocessor-controlled power contactor. �f n= Powerwall Installation Example for Whole-Home Backup (Gateway as Service Entrance and Disconnect) Key NEC References Applicable NEC references may vary with the adopted edition of the NEC and site-specific configurations. Generally, Chapters 1 through 4 as modified by the following NEC sections will apply to Powerwall and the Gateway: Articie or section Description NEC Edition 705 Interconnected Electric Power Production Sources 2014,2017 690.10 Stand Alone Systems 2014 690.71 Storage Batteries 2014 710 Stand Alone Systems 2017 706 Energy Storage Systems 2017 Most .. _.. .. ._—._.._.__ • �� L=_j Sac'+uP uat?`Nay Ma^r �..

Yes. Powerwall and the Gateway are listed to the applicable product standards by Intertek/ETL, an OSHA- approved Natibnally Recognized Testing Latroratory (NRT-t)-See-the-t-abie-abeve-for--a-partial-list-of certifications. If physical certificates are required, please email rowerwall a tesla.com. What safety features does Powerwall include to avoid thermal runaway? To resist single cell thermal runaway, Powerwall complies with requirements in UL 1973 and IEC 62619. For example, UL 1973 includes an internal fire test that ensures a runaway in one cell can't'propagate to neighboring cells. Onboard sensors and the battery management system (BMS) provide multiple layers of protection to detect and stop precursors to thermal runaway. How. much does the AC Powerwall weigh, and will it comply with seismic requirements when wail-mounted? Powerwall weighs 276 lbs. and complies with seismic raryiiimments when wall-mounted according to manufacturer's instructions. It has been evaluated to [CC Acceptance Criteria AC156 for seismic requirements. Installation methods also comply with IEEE Standard 693-2005 for seismic design. Is guidance available for emergency personnel working around a Powerwall that has been physically damaged? - - - - Yes An Emergency Response Guide is available on request. Emergency and maintenance personnel can work safely around Powerwall after opening the system's AC disconnect anti/or breaker on the grid side. A_v_o Iin t i i- =A on batt�Yy — exacerbate a fire involving lithium-ion cells. Does Powerwal require additional vedti-mg-t-o p-r-event- he-accumuiation-of flamr-able=ar•exlslosiue--gases' - -_-- No. Unlike conventional lead-acid batteries, which produce hydrogen gas, the individual cells in the Powerwall are hermetically sealed and do not require additional verililation. NEC [480.9(A)], NFPA 1 Chapter 52, and the 2018 IFC, all make clear venting is not required for lithium-ion batteries. How much electrolyte is in Powerwall? Tesla lithium-ion battery packs do not contain free Liquid electrolyte and do not pose a liquid release hazard. If an enclosure is punctured, there are no electrolytes to "spill" onto the floor. Secondary containment measures are not needed. NOTE: IFC Section 608 does not require spill control or neutralization for lithium-ion battery systems. Secondary containment is not applicable or required for Lhis leuliiiulugy. Is Powerwall's battery path low voltage? Yes. The internal battery pack operates at less than 50 VDC nominal. Unlike legacy battery systems, Powerwall is a fully enclosed. factorv-listed assembly with no accessible battery terminals or live parts. Powerwall's output is AC and matches that of the serving utility. Powerwall's onboard inverter functions exactly like a solar PV inverter. Are the working clearances outlined in the NEC 110.26 applicable to Powerwall? No. Because Powerwall will never require examination, adjustment, servicing, or maintenance while energized, working clearances in Article 110.26 do not apply. Does Powerwall require a separate disconnect? No. Powerwall's onboard switch disconnects all ungrounded conductors and complies with Article 690.71 (2014) and 706.7 (2017). NOTE: These articles require a second disconnecting means at the connected equipment when: • Separated by a wall or partition, or © Input and output terminals are more than 5ft away. This second disconnect will typically be the 2P/30A breaker installed at the point of connection. Can Powerwall be installed outdoors? Yes. Powerwall is a NEMA Type 3R enclosure and can be installed outdoors. What prevents Powerwall from back-feeding the utility grid during a power outage? During a power outage, the Gateway automatically isolates the home from the grid per IEEE 1547. Powerwall and Gateway are both listed to UL 1741 because they are subject to the same anti-islanding rules as a typical grid-interactive PV system. Gateway reconnects to the grid once it is stable for at least 5 minutes. What is the maximum number of circuits that can be backed up for a single Powerwall? The number of circuits that a single Powerwall can back up isn't specified. The duration of backup power is a function of Power' Time, stated in Watt-hours. The maximum continuous output at any given time is limited to 5000W, with a peak output capacity of 7000W for 10 seconds. The number of loads and circuits the customer wants backed up will determine the overall system size, including total number of Powerwalls required. Is Powerwall required to be capable of backing up all the home's loads simultaneously? No. When Powerwall is operating as a stand-alone system, as permitted in 705.40, available current must be "equal to or greater than the load posed by the largest single utilization equipment connected to the system" (not including general lighting loads). Guidance on system sizing may be found in NEC Articles 690.10 [2014] and 710.15(A) [2017]. When in backup mode, what happens if the load exceeds Powerwall's rated output current? Powerwall automatically shuts down. Powerwall's inverter is an inherently power- and current-limited device. If Powerwall is operating at full rated output current and more load is applied, it simply cannot produce more current. The inverter will sense the corresponding voltage change and immediately shut off. There is no risk for over-discharging above the rated nameplate of Powerwall. Inspection Guide In addition to a simpler installation process, Powerwall and Gateway systems are easier to review for safety and code compliance. Primary code references are from the 2014 NEC.

SUNation Solar Systems SUNation 171 Remington Blvd. Solar as it should be Ronkonkoma,NY 11779 To whom it may concern, Since 2018, SUNation Solar Systems has been installing the Tesla Powerwall 2 using means and methods that ensure the safety of our customers,first responders, and other members of the public. During this time, local governments and other authorities having jurisdiction (AHJ) have been working to find the best ways to ensure the safe installation and application of energy storage systems(ESS). Understandably,AHJs have been paying close attention to the fire safety aspects of these systems and installation methods. Some heavily publicized battery-related fires, largely involving cheap, unlisted consumer products of foreign origin have caused some AHJs and fire officials to view ESS with an overabundance of caution.The common flaw among these products is a lack of measures preventing the dangerous phenomenon known as thermal runaway. .Modern ESS such as the Tesla Powerwall 2, by contrast, contain numerous safeguards to prevent thermal runaway and the propagation of fire from one unit to another. Intensive scrutiny and testing are required for modern ESS to be granted the equipment listings that are required by state codes.These systems,when properly installed, can be considered safer than many other existing technologies found within the modern home. Recently, the.Powerwall 2 has surpassed 200,000 installations in the U.S.with no known instances of thermal runaway. The attached UL9540A Fire Test Results and Supplemental Guide are provided herewith to provide AHJs the necessary information to allow Tesla Certified Installers to install the Powerwall 2 in accordance with the manufacturer's spacing requirements (as allowed in the 2020 New York State Residential Code), as opposed to the default 3-foot requirement. The following excerpts from the 2020 New York State Residential Code specify the installation requirements for energy storage systems(ESS): R327.3 Installation Energy storage systems shall be installed in accordance with the manufacturer's instructions and their listing. R327.3.1 Spacing Individual units shall be separated from each other by at least 3 feet(914 mm) of spacing unless smaller separation distances are documented to be adequate based on large-scale fire testing complying with Section 1206.6 of the Fire Code of New York State. The following excerpt from the 2020 Fire Code of New York State describes the large-scale fire testing referenced in R327.3.1: 1206.6 Large-Scale Fire Test Where required elsewhere in Section 1206, large-scale fire testing shall be conducted on a representative energy storage system in accordance with UL 9540A or approved equivalent. The testing shall be conducted or witnessed and reported by an approved testing laboratory and show that a fire involving one energy storage system will not propagate to an adjacent energy storage system. In addition, the testing shall demonstrate that, where the energy storage system is installed within a room, enclosed area or walk-in energy storage system unit, a fire will be contained within the room, enclosed area or walk-in energy storage system unit for a duration equal to the fire-resistance rating of the room assemblies as specked in Section 1206.14.4. The test report shall be provided to the fire code official for review and approval. 1 SUNation Solar Systems i � SUNation 171 Remington Blvd. Solar as it should be Ronkonkoma, NY 11779 The Tesla Powerwall 2 has met the unit level performance criteria outlined in ANSI/CAN/UL 9640A when installed as follows: •The Powerwall must be installed in accordance with accompanying Powerwall 2 mounting bracket as detailed in the installation instructions.

The scope of the report includes the performance criteria outlined in Section 9- Unit Level Testing of ANSI/CAN/UL 9540A:2019 Fourth Edition.The report also includes a summary-of data acquired at the cell and module levels during prior testing. All Section numbers in the report are references to ANSI/CAN/UL 9540A:2019 Fourth Edition, Dated November 12, 2019. PRODUCT DETAILS The device under test(DUT) in the attached report is the Tesla Powerwall 2, model 3012170-XX-Y, which is also the ESS included as part of the Powerwall+all-in-one Solar PU and Storage solution (1850000-XX-Y). Full product specifications and certifications are available on request from all Tesla authorized installers. General product details are outlined on Page 2 of the CSA Group Checklist and Test Result document.

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 confonnance to the performance criteria for each installation configuration. In the unit level test it was demonstrated that; The Powerwall 2 mounting bracket provides adequate clearance horn the wall surface on whirl-I 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 FrP r_.nndiflnn iS t-MM s'ned in an initiatina 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. 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. S - ^ ;.G;\v-I i ES RE:P0RT SUPF'_Ei4Ef I UNIT LEVEL TEST - INDOOR FLOOR MOUNTED Section 9.2 begins on page 99 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.

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 9 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 Compati,biiity 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' ('Home') side of the Backup Gateway's relay. _J #A i 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 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. fj\ CAUTION: Before installing, disconnecting, and/or adjusting current transformers for metering, r 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. JN CAUTION: The Manual Override switch inside the product may,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. 9NOTE: 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.

Mounting Powerwall must follow the guidance outlined in this document. Mounting requirements based on wall type are provided in Appendix A:Powerwall Mounting Details on page 51. Powerwall requires adequate clearance for installation, cabling, and airflow. Do not install anything above Powerwall that limits access to the unit or that might fall and damage the unit. Do not mount Powerwall horizontally or upside down. NOTE: Powerwall has a pump and fan that produce a gentle hum during operation, comparable to a typical refrigerator. The noise level depends on the ambient temperature and the power level of operation. Consider these noise levels when choosing where to install Powerwall. i Powerwall 2 AC Installation Manual 11 TSITE REQUIREMENTS AND PRE-INSTALLATION GUIDANCE Powerwall Identification Newer Powerwalls have slightly different dimensions for mounting-bracket height. Powerwalls may be easily identified by part number and by comparing the back of the Powerwall (see figure below). 'Figure 2.

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 WNII 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 i 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 Powerwall in a warm location prior to installation to help efficiently commission and test the system. 1 Powerwall 2 AC Installation Manual 12 T PREPARING FOR INSTALLATION In the Powerwall Box In the Powerwall Accessory Bag Powerwall Accessory Bag: Tesla P/N 1104517-00-x 1.

NOTE: Maximum PCS Controlled Current setting: 200 A. Panel Limit Feature 11 Site Controller Software UL 1741 Power Control System requirements and the "Panel Limits" feature are implemented in the Tesla Site Controller software. Tesla's Site Controller software is used across all Tesla Powerwall sites. Site Controller software controls the entire energy storage site and communicates over CAN and Wi-fi. The Backup Gateway or Neurio (WI/W2) meter are part'of a Powerwall system and contain two current sensors, one per phase, to act as a site and/or solar meter, which measure the grid and uncontrolled power production sources. Feature Introduction As per requirement from NFPA 70: 2020, 705.13, Tesla Site controller software has implemented a Panel Limit feature that monitors the amperage flowing into an electric panel / busbar from all controlled and uncontrolled sources (Grid, Solar Inverter, and Powerwall). As the measured current approaches the configured panel limit, the Site Controller first reduces the current contribution of batteries, then limits the output of solar. If the measured current of all sources combined exceeds the configured Panel Limit for the site, the output of all PCS-controlled power production sources will be curtailed to 0. Solar Meter Site Meter i Uncontrolled Source(s) 01 E--- --- Grid Controlled Source(s) "Virtual Panel" or Busbar Notes • The "Virtual Panel" may include several panels and conductors, and is considered as one single panel with respect to the Panel Limit feature. • Grid is measured by one or more physical site meters to measure the full current flowing into the virtual panel from the grid. • Uncontrolled Sources include external Solar Inverters or similar sources to the virtual panel • Controlled Sources include Tesla ACPW and Tesla Powerwall+ in any quantity and combination (e.g. two ACPW and one Powerwall+) Powerwall 2 AC Installation Manual 37 STEP 5: MAKE COMMUNICATIONS CONNECTIONS Example Single Line Diagrams for Common Installation Configurations • ACPW and Uncontrolled Solar Inverter and Gateway 2 North America for Whole Home Backup Virtual Panel 5'ite 1.leter Solar Meter Solar inverter Backup panel Backup Gateway 2.

Powerwall 2 AC Installation Manual 38 STEP 5: MAKE COMMUNICATIONS CONNECTIONS Settings (2020 NEC, 705.13(B)) • The panel site limit setting is restricted to Tesla personnel only and can be set in the config file with "panel_max_current" option. • As there may be more than one physical panel and conductors included, the panel limit is set to the rating of the smallest busbar within the "Virtual Panel". • By default, all Backup Switch installs are automatically configured with a 100A Panel Limit. As 100A is the minimum allowable size for a single family dwelling per NEC 230.79 (C), this protects any main panel busbar for a single family dwelling with any quantity of Tesla Powerwall Overcurrent Protection (2020 NEC, 705.13(C)) • The Tesla Site Controller software is certified under UL 1741 PCS as secondary overcurrent protection. • Overcurrent devices are still required for each circuit as required by the National Electrical Code. • Software curtails the output of the battery and solar as load approaches the Panel Limit. Once battery and solar have been curtailed, loads would be fed exclusively from the grid. Thus the busbar is protected by the main breaker, or the breaker in an upstream panel, as intended prior to the addition of secondary power sources. Single Power Source Rating(2020 NEC, 705.13(D)) • Each Powerwall connection to the electrical panel requires an independent 30 A circuit breaker. • This breaker serves as the disconnect for the unit, and must be wired in accordance with local wiring codes and regulations. • This breaker is by design smaller than the smallest panel used within the system, and smaller than the panel limit. • The service disconnect overcurrent rating is unchanged based on the Panel Limit. Access to Settings (2020 NEC, 705.13(E)) • The Panel Limit feature is only adjustable by a Tesla personnel. • The PCS controlled current setting will be auto enabled and the only method to change it will be to call Tesla, and for a tier 2 support person to adjust the setting via Tesla software programs, that are locked behind Tesla username and password. Install Optional Remote Disable Switch L&Qf NOTE: This section provides guidelines on a system functionality. Please consult your local AHJ or Utility before use. The Backup Gateway 2 can be wired to include an external Remote Disable switch that simultaneously commands all Powerwalls to become idle and enter a safe mode. Installation Instructions The Remote Disable switch is wired through a low voltage, 12 V DC, control circuit connected to the Gateway AUX port.

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, Tesla 100 A CTs connected to the Internal Auxiliary Meter can be used to measure loads less than 100 A, or a Remote Meter can 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 68 for further guidance on metering. • See Appendix E:Installing a Neurio Energy Meter on page 69for Remote Neurio Meter installation instructions. Powerwall 2 AC Installation Manual 43 T STEP S: INSTALL ENERGY METERING 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 0-7-1 r P�;y.

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 85 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 82 for more information. Powerwall 2 AC Installation Manual 44 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 56 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.

Beginning with Powerwall firmware 21.13, Tesla supports both the Neurio W1 (Tesla P/N 1112484-02-x) and Neurio W2 (Tesla P/N 1112484-04-x) meters and their accessories. While the meters serve the same applications, there are some differences between them which will be called out in the following sections. It is very important to note that Neurio W1 accessories are not compatible with the Neurio W2 meter, and Neurio W2 accessories are not compatible with the Neurio W1 meter. Important Notes Powerwall Software Version Neurio W2 is supported in Powerwall version 21.13 and later. When commissioning systems with the Neurio W2 meter,ensure the software has been updated to at least this version to allow pairing and reading from the meter. Neurio W2 Currently Only Supports Wi-Fi Connections Neurio W2 currently only supports Wi-Fi connections; no wired (RS-485) connections are supported at this time. No 800 A CTs Currently there are no 800 A CTs available for the Neurio W2 meter. For sites requiring 800 A CTs, a Neurio W1 meter with Neurio W1 800 A CTs is available for purchase. CTs are not Backwards Compatible The Neurio W2 meter uses a new 4-wire CT which is not compatible with Neurio W1 meters (nor are Neurio W1 CTs compatible with Neurio W2 meters). Powerwall 2 AC Installation Manual 69 T APPENDIX E: INSTALLING A NEURI® ENERGY METER Figure 26. Neurio W1 Meter Kit with 200 A CTs ;j �-- Figure 27. Neurio W2 Meter Kit with 200 A CTs o NOTE: When replacing a Gateway,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's internal site meter is deselected in Commissioning. Powerwall 2 AC Installation Manual 70 APPENDIX E: INSTALLING A NEURI® ENERGY DIETER Wireless Communication to the Backup Gateway The Neurio Energy Meter (Tesla P/N 1112484-00-x) is 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 with the Neurio Wl meter, 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. FD,�'�NOTE: The Neurio W2 meter only supports Wi-Fi connections; there is no RS-485 harness available for the Neurio W2 meter. If the meter is located outside the Gateway, the harness leads can be extended by splicing additional wire to the harness. See Maximum Tesla CT Extension on page 21. 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.

FW N TE: CT extensions cannot be combined unless the connection point between extensions remains ccTs ible (for instance, inside a panel). 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 Povverwa|| 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, inoonfigunationsvvheraitisnotAossib|eto |ooateCls 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 82 for more information. See Appendix C on page 61 for system wiring diagrams depicting CT placement for various wiring configurations. powenwa||2 AC Installation Manual 74 APPENDIX E: INSTALLING A NEURIO ENERGY METER 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.

Multiple Conductors Passing Through Single Neurio W1 CTs e e lJ.11 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 (for Neurio W1 meters: Tesla P/N 1129625-00-x, for Neurio W2 meters: Tesla P/N 1622286-xx-y) can be used to connect two CTs on the same phase to a single meter port. Figure 35.Y Cables Connecting Neurlo W2 CTs on the Same Phase 1 M el aLgel - M] L11 El Powerwall 2 AC Installation Manual 76 APPENDIX E: INSTALLING A NEURI® ENERGY METER For the Neurio W1 meter, 800 A CTs are also available for larger service sizes (Testa P/N 1447689-00-x). The 800 A CTs can only be used with the Neurio W1 meter, and 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 input channel can measure up to 400 A. When 800 A CTs are used in parallel, each input channel can measure up to 1100 A. 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 screws provided in the meter kit, attach the mounting plate 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. Wire the Voltage Taps 1. Plug the voltage line harness into the meter. 2.

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. Powerwall 2 AC Installation Manual 82 APPENDIX F: FEATURE NOTES 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. When the system is wired for load shedding, the controlled load breaker can remain on the backup loads panel.

If issues still persist after rebooting the Gateway, reset the Backup Switch using the 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 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 steps to ensure it is in the correct location and orientation: • Adjust the Amps/kW slider to see what the CTs are reading. • Verify the on-screen values for the CT against the applicable meter(such as the solar inverter meter or utility meter). • Ensure that: o Site CTs are positive for import, negative for export. o Solar CTs are positive when the PV array is producing power (Solar is NEVER negative during daytime). Powerwall 2 AC Installation Manual 85 APPENDIX G: INSTALLATION TROUBLESHOOTING ' 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. -------------- Solar CTs should only meter generation sources. It is never recommended to meter both generation and r 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. — Reset the Backup Gateway If experiencing issues with the Backup Gateway, reboot the Gateway using the RESET button (1 below). I Power Cycle the System If resetting the Backup Gateway does not resolve issues, power cycle the system as follows. To power the system off : 1. Turn off solar equipment. 2. Turn off all Powerwalls. 3. Open breakers feeding Powerwall and solar. 4. Open breaker feeding Gateway. 5. Disconnect communication wiring. Reverse steps to power the system on. Powerwall 2 AC Installation Manual 86 T APPENDIX H: MULTI®PO ERWALL 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. Powerwall 2 AC Installation Manual 87 APPENDIX Ho MULTI—POWERWALL INSTALLATIONS 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. 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 90for 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 r Powerwall 2 AC Installation Manual 88 APPENDIX H: MULTI-POWERWALL INSTALLATIONS 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 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. S. 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 90. 6. Record the impedance measurements. 7. Repeat steps 3-6 for L2.
