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 • 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 several functions: • Monitors the grid for outage • 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.

Generally, Chapters 1 through 4 as modified by the following NEC sections will apply to Powerwall and the Gateway: Article 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 s Key Specifications & Certifications (Full datasheets provided separately) Powerwall Electrical Energy 13.5 kWh AC Voltage (Nominal) and 120/240 V: 24 A Maximum Continuous Current Frequency (Nominal) 60 Hz Power, max continuous 5 kW(charge and discharge) Power, peak(10 seconds) 7 kW (charge and discharge) Overvoltage Category Category III Max Supply Fault Current 10 kA Max Output Fault Current 32 A Powerwall Environmental & Certifications Operating Temperature -20°C to 50°C (-4°F to 122°F) Enclosure Type NEMA 3R Ingress Rating IP67(battery and power electronics) IP56 (wiring) Wet Location Rating Yes Seismic Rating AC156, IEEE 693-2005 (high) Safety Certifications (partial list) UL 1642, UL 1741SA, UL 1973, UL 9540 NRTL Intertek/ETL Powerwall Mechanical Height 45.3 in Width 29.7 in Depth 6.1 in Weight 276 lbs Gateway Electrical Disconnect Current 200 A Overcurrent Protection Breaker 100-200 A(Service Entrance configuration) Overvoltage Category Category IV Fault Current Withstand Rating 10 kAIC(Configurable to 22 kAIC) AC Meter Revenue grade Service Rating Suitable for Use as Service Equipment Gateway Environmental & Certifications Operating Temperature -20°C to 50°C (-4°F to 122°F) Enclosure Type NEMA 3R Ingress Rating IP44 Safety Certifications (partial list) UL 1642, UL 1741, IEC 61000-6-3, IEC 62109-1 NRTL Intertek/ETL Gateway Mechanical Height 29.1 in Width 14.9 in Depth 5.1 in Weight 36 lbs 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). (VOTE: 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. Additional references [in brackets] are from the 2017 NEC. General Requirements Listing verification - Equipment bears the mark of a Nationally Recognized Testing Laboratory. 90.7, [706.5] © Manufacturer's installation instructions followed. 110.3(8) The completed installation appears to be neat and of good workmanship. 110.12 Working clearances are in accordance with 110.26 for any components that are "likely to require examination, adjustment, servicing, or maintenance while energized." o Note that Powerwall has no accessible DC battery interconnections within the unit, and does not require maintenance while energized. o The ventilation clearance requirements found in 480.9 do not apply to this technology. Tesla Powerwall complies with [706.10(A)] using a pre-engineered ventilation solution.

The purpose of testing was multifold, with the main intents being to demonstrate 10"as adequate distance for spacing to prevent fire propagation unit to unit, to show that light masonry material is sufficient to prevent fire from the unit from compromising the structure and adjacent exposures, and to show that gases and fire from the battery do not pose a significant risk to adjacent pathways of egress. To demonstrate this, DNV GL built seven "wall samples."These samples were approximately 10ft wide, 8ft tall walls, as they would be built in a structure, from several different building materials including brick, concrete, Stucco, CMU or cinder block, hardie board, and vinyl siding. All but the concrete and CMU wall also had an accompanying soffit and 3'section of shingled roof built with them as well. Two Powerwalls were then placed, as they would be installed, on the walls. Internal heaters in one unit would then be activated to drive one unit to failure. Six tests were then run, with the seventh, being similar to the sixth but with worst results expected, cancelled following the sixth test. To answer the questions posed, DNV GL collected temperature and off gas data from the adjacent unit as well as from numerous points around the unit as well as on and above the wall samples. DNV GL also collected offgas data from the units as well as flammability data. DNV GL believes testing demonstrated that 10"is sufficient for spacing against non-flammable walls, with the one test involving a flammable wall allowing propagation after the wall itself caught fire. DNV GL also believes that the units pose minimal risk to the structure even when fully consumed by fire when the units are installed against non-flammable or flame retardant walls; this includes light engineered masonry materials such as hardie board. Finally, DNV GL believes the units do not pose considerable risk to open egress pathways based on gas emissions as well as flame direction from the unit. For First Responders: Gas monitoring, performed during both this testing project and other projects, has demonstrated that in an open environment, either outdoors or in a covered but open-sided structure, there is no major toxicity risk from Tesla battery fires beyond what would be encountered in a typical class A fire. However, Carbon Monoxide (CO) levels in and around the unit will be elevated and may remain so long after the fire is extinguished, as hot batteries continue to generate gas. For this reason, DNV GL recommends that personal protective equipment (PPE), including self-contained breathing apparatus (SCBA), be worn until CO levels are shown to reach safe levels, even during overhaul and in exterior environments. In addition, DNV GL and their fire service partner, Rescue Methods, do not recommend first responders pierce or cut the units during any fire or emergency event. Such procedures run the risk of triggering further failure and thermal runaway even after the systems have stabilized post-fire. For all energy storage installations, DNV GL and Rescue Methods recommend that an emergency management plan or standard operating procedure (SOP) is developed, that owner/operator contact information is available at the site, and that subject matter experts (SMEs) are contractually obligated to be available in a timely manner in case of emergency. DNV GL- Document No.: 10075610-HOU-R-01-D, Issue: D, Status: Release Page viii www.dnvgl.com I INTRODUCTION KEMA-Powertest, LLC (DNV GL) was contracted by Tesla, Inc. (Tesla) to perform a live burn of their 13.5 kWh Powerwall product. Tesla's purposes for testing were to provide the large-scale testing data to satisfy exemption requirements in New York City and for states following the International Fire Code and NFPA 1 and to generate data with which to inform code development for the same codes. DNV GL was tasked with burning seven pairs (fourteen units in total) of Powerwalls mounted on seven different common building materials and with five different soffit materials. The Powerwalls were spaced per installation requirements in each test to verify no propagation as a result of installed spacing. Ultimately, testing demonstrated positive results with regard to a lack of fire propagation when installed on several common building materials. DNV GL is of the opinion that this testing data can provide confidence to AHJs and code officials regarding placement of the units in the manner Tesla has proposed. 2 TEST SETUP Tesla shipped fourteen Powerwall 2 units from its Sparks, Nevada facility in January 2018 to the testing facility in Piqua, Ohio via ground freight. The units were shipped at approximately full charge and were received by members of Rescue Methods and Piqua Fire Department. Because of the cold weather in January, the units were stored in a climate controlled room at approximately 55°F. Prior to testing, the units were photographed and all relevant product descriptions, serial numbers, and dimensions were recorded. Each test entailed a pair of Powerwalls mounted to a section of wall constructed of one of seven common building materials with insulation, soffit, and shingles. Further description of the wall sections may be found below in 2.3. In each pair, one unit was fitted with thermocouples to measure temperature impact while the other unit was fitted with cartridge heaters to force a number of cells into thermal runaway. Per Tesla's direction, all Powerwalls were placed such that the edge to edge distance was 10". This is demonstrated below in Figure 2-1 and was verified for every test after installation.

Four tests were conducted on the first day, with two additional tests on the second day. The seventh test was cancelled at the request of Tesla, with the expectation that the results would not differ from those of Test 6. DNV GL agreed with this assessment. After testing, the burned units were cooled via fire hose with several tens of gallons being flowed directly into the exhaust ports. In five of the six tests, the adjacent units showed no sign of propagation and no water was directly applied to the units. After testing, the units were dismounted from the wall, photographed, and placed horizontally on pallets for disposal. Disposal was handled by Retriev Technologies of Lancaster, Ohio. DNV GL— Document No.: 10075610-HOU-R-01-D, Issue: D, Status: Release Page -2 www.dnvgl.com 2.1 Data Acquisition and Video Unlike testing conducted for standards certification where test set-up must comply with pre- determined requirements, DNV GL and Tesla were able to work flexibly to collect data as needed to support research and potential code exemption. As such, DNV GL moved thermocouples during testing as needed to collect better data or highlight points of interest during certain tests. In addition to data acquisition, which will be discussed in later sections of this report, DNV GL and Rescue Methods also placed three thermal cameras, three regular cameras, and three Firecams around the setup as illustrated in Figure 2-2. Two thermal cameras were placed to record the front side of the wall section, with one pointed at the center of each Powerwall. A third thermal camera was placed behind the wall, recording the center of the wall section. Two Firecams were placed to the side, with lateral views of the wall section facing toward the unit under test, one at the Powerwalls'vent level and one at roof level. Directly opposite, a third Firecam was placed between the top of the Powerwalls and the bottom of the roof. Finally, three regular cameras were used, with one placed in the front, one recording from the rear, and a third installed to capture impact on the soffit.

Behind unit Figure 2-2 Camera and thermal measurement device placement 2.2 Gas analysis DNV GL utilized a Fourier transform infrared (FTIR) gas analyzer, a Gasmet DX4000, to sample off-gas composition and concentration. This unit sampled the air inside the test space at 5 second intervals to monitor the typical off-gases from batteries, based on DNV GL's experience. The Gasmet unit was placed approximately 5 feet above the test specimens with the probe tip sometimes directly above the DNV GL— Document No.: 10075610-HOU-R-01-D, Issue: D, Status: Release Page -3 www.dnvgl.com unit and sometimes aligned more into the soffit (when present). The gases sampled and their units of measure are shown below: Water Vapor (H2O, %) Carbon Dioxide (CO2, %) Carbon Monoxide (CO, ppm) Nitrogen Monoxide (NO, ppm) Nitrogen Dioxide (NO2, ppm) Sulfur Dioxide (SO2, ppm) Methane (CH4, ppm) Ethane (ppm) Ethylene (C2H4) Hydrogen Chloride (HCl, ppm) Hydrogen Fluoride (HF, ppm) Hydrogen Cyanide (HCN, ppm) Benzene (ppm) Toluene (ppm) Ethanol (ppm) Methanol (ppm) Propane (ppm) Oxygen (02, %) In addition to the FTIR analyzer, Rescue Methods personnel near the test were equipped with MSA- brand four-gas analyzers that can detect Oxygen (02), Carbon Monoxide (CO), Hydrogen Cyanide (HCN), and the lower explosive limit (LEL, combustible) of the gas mixture. For the purposes of this test, the primary use was to monitor CO, as DNV GL's experience suggests that batteries continue to off-gas CO at high levels long after being extinguished. Measurements from these sensors were monitored and recorded periodically, based on events observed visually and approaches to the unit. 2.3 Wall sections Seven wall sections were built from common building types for installations per Tesla's specifications. The walls were constructed prior to testing and transported to the site the week of testing. They were constructed to spec, per Figure 2-3 and Figure 2-4 on the following page, from materials outlined in Table 2-1. No defects were observed in any of the walls. The brick, concrete masonry unit (CMU), and concrete wall were unable to cure sufficiently due to low temperatures, and displayed some spalling during testing. This had no effect on the tests. Wall 1, with vinyl siding and poly foam insulation, was not used. The test order was not based on the wall number provided in the table below as well.

In each test, Tesla provided five thermocouples in each adjacent module, with one in the center and one in each of the four corners of the Powerwall. In addition, DNV GL provided three to four wall mounted thermocouples around the burned unit, as well as three to five thermocouples on a mast mounted over the roof, depending on the test. One thermocouple was always placed directly behind the center of the unit under test while a second thermocouple was placed on the back side of the wall behind the unit under test. During some tests, a third thermocouple was placed either inside the wall behind the unit under test (and centered of the unit under test), in the flame path (approximately three feet above and to the right of the unit, as shown in Figure 2-2), or high on the backside of the wall to determine temperature through the wall (identical to flame on backside). DNV GL also recorded ambient temperature in the burn area with a thermocouple. DNV GL also utilized two water-cooled heat flux gauges. During the first test, one was placed directly in front of the unit under test while the second was placed 5 feet to the side. Following the first test, the unit to the side was left in place, while the unit to the front, which did not provide reliable results, was relocated to the other side view of the units. 2.5 Ignition methods Module ignition was initiated by conductive heat exposure. Cartridge heaters were placed into the module"potting"around the cells. For all tests, DNV GL implemented an approximately ten minute "pre-heat"to uniformly heat the cells between the heaters at which point the power supply to the heaters was increased to maximum current. Tesla's observational experience from prior tests indicated approximately 5-10 minutes of directed heat exposure would lead to failure. In all six tests, DNV GL— Document No.: 10075610-HOU-R-01-D, Issue: D, Status: Release Page -6 www.dnvgl.com the ignition method was successful in igniting cells within this expected time frame and in ensuring consistent propagation. 3 TEST RESULTS AND DATA 3.1 Test 1: Brick surface Test 1 was performed on the brick wall, which was built in situ to prevent potential structural issues that could have been caused during transportation. DNV GL utilized the greatest number of data acquisition devices on this test. From this test, however, it was demonstrated that the higher number of devices did not contribute to higher resolution output, and so redundant devices were removed. Further, the thermocouples housed in the Powerwall adjacent to the device under test failed to provide information as fire from the device under test destroyed the cables for these thermocouples. Data from the unit before damage to the cables showed no appreciable temperature gain in the minutes prior to the destruction. Temperature data from the thermal camera trained on this module showed no adverse skin temperatures on the unit during or following testing. As such, in DNV GL's opinion, these changes in test set up still allow for valid results.

The vinyl soffit was quickly compromised, dropping burning plastic down in the adjacent area, which led to damage of numerous thermocouples. The roughly 3.5' spacing between the top of the Powerwall unit and the soffit was likely insufficient and in cases where flammable soffit or other materials exist, additional space may be required to minimize propagation.

A .I w,.. +..e...._ Figure 3-3 Peak flame output from device under test during Test 1 DNV GL allowed the unit to burn freely, allowing for higher mast temperatures than were seen during other tests where the roof and soffit were more protected, as will be discussed in later sections. DNV GL also observed discrepancies during testing in the temperatures behind the device under test and inside the wall behind the device under test, which were considerably higher than in all following tests. It is possible these thermocouples were also damaged during testing, as the rear thermal cameras do not show that back wall temperatures rose appreciably. Spalling of the mortar, which was not fully set, may have allowed fire in and around the inside of the wall, though damage to the thermocouples is more likely since their measured temperatures were inconsistent with all other testing. 3.2 Test 2: Concrete surface Following the destruction of numerous thermocouple cables in Test 1, several changes were made to temperature measurements to improve the testing set up. Two thermocouples were removed from the mast above the wall section, with placements of the remaining thermocouples instead at 1', 3', and 5' above the roof line. For Test 2 there was no roof or soffit, and flame temperatures could be measured more directly from the mast, as opposed to Test 1, where ignition of the soffit and roof trusses became the main source of mast temperature increase. Three thermocouples recorded wall temperatures, reduced from four in Test 1. The heat flux gauge directly in front of the unit was also moved to the far left side, 5'from the wall's edge. Finally, the device under test was moved from the left Powerwall unit to the right Powerwall unit. This aligned the device under test under the FTIR DNV GL— Document No.: 10075610-HOU-R-01-D, Issue: D, Status: Release Page -9 www.dnvgl.com probe. In this test, the lack of roof also allowed the FTIR probe to be placed directly above the device under test, as opposed to tucked into the soffit. Unlike temperature data, which is best displayed on a per test basis, gas data is better displayed relative to other tests, and as such is shown and discussed in Section 3.7 in aggregate. With data acquisition improved, much more clear temperature data emerged, a trend which was consistent for the remainder of the tests. A temperature of roughly 200-250°C was observed directly behind the device under test. Temperatures inside the wall and on the back of the wall, in contrast, showed only negligible increases, as shown in Figure 3-4. Temperatures in the adjacent unit on the fire side rose to between 30 °C and 50 °C, as shown in Figure 3-6. As ambient temperatures were roughly 0°C during testing, a higher ambient temperature could potentially raise an adjacent unit temperature to a less favorable range. However, the thermal management system was disabled for the test, so under normal operations, such a system could mitigate such concerns.

This material showed a high level of resilience to fire relative to other engineered building materials and in line with more traditional masonry materials; protecting the roof trusses well and preventing significant conduction of heat through the wall, as shown in Figure 3-9. As fire did not propagate into the roof, with the exception of briefly whipping around the open sides, mast temperatures were minimal as flame simply did not reach beyond the roof, as shown in Figure 3-10. As will be discussed further in Section 4.1, the material in this test demonstrated that fire-rated materials are capable of effectively protecting against fire spread from Powerwall systems undergoing catastrophic forced failure. In Test 3, as shown in Figure 3-11, direct heat exposure in the adjacent Powerwall again lead to an internal temperature increase of roughly 40°C. 400 Wall Temperatures During Test 3 350Back of Wall Inside Wall Behind DUT 300 III 0 250 i 200 CU a E 150 H 100 50 0 0 500 1000 1500 2000 2500 time (s) Figure 3-9 Wall temperature during Test 3 DNV GL— Document No.: 10075610-HOU-R-01-D, Issue: D, Status: Release Page -13 www.dnvgl.com Mast Temperatures In Test 3 50 5ft 3ft 40 1ft Ambient U 30 0 N L 20 L Q 10 0 -10 0 500 1000 1500 2000 2500 time (s) Figure 3-10 Mast temperatures during Test 3 Tesla Thermocouples 50 Tesla TC1 Tesla TC2 40 Tesla TC3 Tesla TC4 Tesla TC5 U 30 0 N L 20 L CD Q- 10 10 0 -10 0 500 1000 1500 2000 2500 3000 time (s) Figure 3-11 Adjacent Powerwall temperatures during Test 3 DNV GL— Document No.: 10075610-HOU-R-01-D, Issue: D, Status: Release Page -14 www.dnvgl.com QjF SQ�Iyo 1802 54375 Main Road Fax (631)765-9502 P.O.

Unlike previous tests, where a thermocouple was placed inside the wall, in Test 4, the third thermocouple was instead placed in the expected flame path on the front side of the wall. The device under test's thermocouple shows slow warming, in Figure 3-14, when ignition occurs, while the flame path thermocouple quickly rises to 800°C, which is the commonly observed temperature for smaller battery fires and combustion.

As it was established in Test 1 that the vinyl soffit would melt and catch fire quickly, DNV GL tested the hypothesis that a piece of masonry board would offer sufficient protection from fire exposure. Leftover 5/8"gypsum board from the construction of Test 3's wall was roughly installed over the vinyl soffit, with ends left open and no sealant used. It is expected that more rigorously installed 5/8"gypsum board, with sealed ends, would offer greater protection. The result showed that this simple material may effectively protect exposures from fire, as posited. Additionally, in Test 5, a fourth wall thermocouple was placed in the soffit above the device under test. As can be seen in Figure 3-18, temperature in the soffit increases minimally relative to past tests. This result is further supported in Figure 3-21, which shows the roof trusses nearly 35 minutes after initial combustion with no apparent heat damage at all.

Based on previous tests, it was expected that the siding would quickly melt and ultimately burn, compromising the entire roof and wall structure and likely resulting in propagation to the neighboring unit. Great care was thus taken to protect the roof at least with the intent of preserving structural integrity.

As such, the seventh test was cancelled. 3.7 Gas Data As previously noted, display of gas data in the context of other tests allows for a more comprehensive understanding of the potential risks. As such, multiple figures are shown below that highlight the trends with respect to gas levels during testing. Immediately apparent, and a positive finding, is the low levels of HCl, HF, and other toxic gases detected. Across all tests, high levels of CO are seen, though Tests 3 and 5 (Figure 3-28) showed levels approximately an order of magnitude lower than Tests 1, 2, 4, and 6 (Figure 3-27). DNV GL has theorized that reduced CO levels in Tests 3 and 5 can be correlated with Hardie board soffits or soffit covers, which preserved the roof and kept direct flame and smoke away from the FTIR probe.

Although these off-gases were expected in Test 6, as the entire wall was completely consumed and these gases are known to be released from the wall surface, it is not clear immediately what the source of HF was in Test 3. As with Tests 1, 5 and 6, the FTIR probe in Test 3 was tucked into the soffit, thereby limiting its ability to detect offgas unadulterated. Further, in Test 3, the soffit was comprised of hardie board as opposed to vinyl.

Again it is unclear what trend is leading to this result, as the conditions varied across the tests (FTIR in the soffit, FTIR in the smoke plume, and observed completely consumed wall, respectively) Test 4 saw multiple single points of benzene, but could also be attributed to noise, as none was greater than a single data point. Given that Test 2 was most directly sampling the smoke plume, it is assumed that greater concentrations of benzene were present directly in the smoke plume and did not permeate through the soffits in other cases. In Test 1 as well the soffit was destroyed quickly once exposed to fire. Of note as well is that benzene IDLH is 500 ppm and in all cases the measured value was well below that.

As expected, masonry and masonry products did not show signs of flammability or risk from failing units and even loose masonry board over flammable exposures proved sufficient to stop propagation to flammable materials such as vinyl siding. Vinyl siding did exhibit less than positive, albeit expected, results in regards to heat and flame exposure, and it is not clear that this material makes for a suitable backing for the Powerwall, though the types of failures induced for this testing are themselves highly unlikely. Flame temperatures from the failing units were in line with typical Li-ion battery fires, with temperatures in the direct flame pathways in the 750-800°C range. For extinguishing purposes, the vents on the upper sides of each Powerwall serves as useful entry points for diligent fire fighters to dump water into once the initial flames have died down and the fuel load is diminished or completely exhausted. In the case of internal failures, the consumption of the cells inside is indicated by the heat damage and loss of paint on the front of the unit, with the entire bottom two thirds being lost as indicative of total loss of all cells.

Though Test 3 showed that a hardie board wall with hardie board soffit are completely resistant to fire and protect the internal structure, Test 5 demonstrated that hardie board placed, even loosely, over flammable exposures can protect them from propagation. As regulations in New York City currently under development suggest that heavy, fire rated masonry needs to be placed over a large perimeter adjacent to the installation, these tests suggest that even lighter masonry board placed over flammable exposures should sufficiently limit risk of fire spread from failing units. While it remains unclear what distance is required to protect flammable exposures where distance alone serves as the barrier, hardie board has demonstrated that it may effectively block direct fire impingement from very short ranges. 4.2 Discussion of gas data Though high levels of CO are generated in all tests, HCI and HF possess IDLH levels of 50 ppm each, much lower than CO. These levels were observed in tests 3, 4 and 6. The presence of HCI is attributed to the presence of Chlorine (CI) in many plastics, including frequently the plastics comprising lithium ion batteries typically found in the wrapper or the separator. During combustion, it easily forms HCI. HCI is common, in many plastics fires as DNV GL discovered during Consolidated Edison testing' and on a per mass basis relative to plastic is emitted in equal concentrations or greater from plastics than from batteries. HCN and Benzene are also commonly generated in all fires. The presence of HF has a more complicated explanation. The simplest explanation involves the consumption of fluoridated plastics. DNV GL has observed high levels of HF when fluoridated plastics are present, such as PVDF. Other materials may possess some quantity of fluorine as well which results in the emission of HF. In cases where fluoridated plastics are not present, the source of fluorine may come from within the cell itself, as the dissolved salt in Li-ion electrolytes is lithium hexofluorophosphate. Chemical kinetics show that water (H2O) and this dissolved salt may bond to form HF, though this reaction would occur deep in the cell, and the likelihood of this highly reactive molecule making it into the atmosphere are lower. In some previous testing, HF has appeared in inert atmospheres and in other cases where individual cells have vented but not combusted. From this, it is believed that the pure degradation of the electrolyte after it has been emitted from the cell without pyrolysis or combustion creates the conditions necessary for HF to be generated in the atmosphere. With that, an exact explanation for the presence of HF cannot be deduced, but given its absence in tests without plastic construction materials, one explanation for increased levels may be related to the construction, not the battery. Additionally, the events are short lived and only barely exceed IDLH. They also, in one case, occur when the FTIR probe is directly exposed to the smoke plume; this is also the case for the detection of HCI in all three cases. This suggests that limiting direct exposure to battery fire smoke would greatly limit the toxicity concerns, aside from short exposures to higher concentrations of CO, which again are greatly mitigated by the presence of an intact soffit.

The presence of any walls or barriers, let alone proper exhaust, s remove these gases and allow for unimpeded egress. BUILDING DEPARTMENT TOWN OF SOUTHOLD 5 CONCLUSION Testing was completed on six pairs of Powerwalls installed on six walls comprised of common building materials. Though vinyl siding yielded less than positive results in regard to fire propagation, and ultimately allowed for propagation to adjacent units, hardie board, and likely any similar lightweight masonry product, may prove highly useful in protecting flammable exposure. In all but the vinyl siding test case, fire from the Powerwalls failed to heat the interior of the walls to dangerous levels. Finally, toxic gases generated by the units during fire should not pose a risk to occupants inside structures and should also pose no risk to egress so long as smoke from the units have not filled a corridor.

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 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. WARNING: All Powerwalls in the system must be installed on the 'Backup' ('Home') side of the Backup Gateway's relay. WARNING:When Powerwall is installed in a dwelling unit, fire detection and protection equipment AL 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. 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. CAUTION: The Manual Override switch inside the product may not be used to simulate a grid outage ' 3 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. 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.

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. Powerwall 2 AC Installation Manual 11 SITE 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 (O°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 Powerwall in a warm location prior to installation to help efficiently commission and test the system.

Panel Limit Feature 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 (W1/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. 501ar Mettr. site,Met& Uricbrttrolled Sources) I-- 1 _.... ......................

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 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.

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 (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 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 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 111 a '7g 4 ; r „F Ta e..

The C73 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.

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 Powerwall 2 AC Installation Manual 88 APPENDIX : 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. !
