The TESLA general warnings and info state "Do Not install near heating equipment". Where you are proposing it is in close proximity to the air handlers.. and while it may be on the non service side of the equipment,there is still a return in the air handler,as shown in your pictures,which means the existing mechanicals draw air from the basement as needed to function properly. Now if we install this powerwall and it ignites,there is the potential for the air handier to pull it in and circulate it thru the house, and why we are suggesting to build a separate and rated mechanical room for just the proposed new units. Additionally, NYS residential code R327.8 states that rooms and areas containing the storage systems must be protected (walls&ceilings)on the system side of the room or area which contains the system. While I see the 8x12 area of the fire rated drywall on the ceiling,this is not sufficient. It must be the ENTIRE ceiling of the area containing the system,so if this is one large unfinished basement, we are requiring the.entire basement to be fire rated. Again, its 1 A our suggestion to build a separate, rated mechanical room for these units, as it will eliminate the need for you to rate the entire basement space. If you have any questions,you are more then welcome to call myself, or the building inspector who has been reviewing this application as well. ✓Na'ncy Dwyer Building Permits Examiner Town of Southold Building Department Annex Building 54375 Main Road Southold,NY 11971 (631) 765-1802 From:Gina Marie Cicero<gcicero@sunation.com> Sent:Wednesday,June 16, 202112:52 PM To: Dwyer, Nancy<nancvd@southoldtownny.eov> Subject: Fwd:SUNation permit application for 590 Arrowhead Lane, Peconic Hello Nancy, I am just reaching out to see if we have any updates on the status of the permit for this project from when Tammy Lea sent you the revised plans and code information.

Architectural Design•Residential•Light Commercial Additions•Extensions•Conversions Construction Estimates/Oversight•Expediting•Inspections TSSLR Powerwall 2 AC & Backup Gateway: Permitting & Inspection Support for Tesla Home Energy Storage System Summary Description Powerwall 2 AC (Powerwaii) 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 • 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.

Yes. Powerwall and the Gateway are listed to the applicable product standards by Intertek/ETL, an OSHA- approved Nationally Recognized Testing Laboratory (NRTL). See the table above for a partial list of certifications. If physical certificates are required, please email nowerwallCa-0tesla.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, UI 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 wall-mounted? Powerwall weighs 276 lbs. and complies with seismic requirements when wall-mounted according to manufacturer's instructions. It has been evaluated to ICC Acceptance Criteria AC156 for seismic requirements. Installation methods also comply with IEEE Standard 693-2005 for seismic design. Is_auidatice-available for emerrency personnel working around a Powerwall that has been physically damaged? Yes. An Emergency Response Guide is available on request. Lmergency and maintenance personnel can work safely around Powerwall after opening the system's AC disconnect and/or breaker on the grid side. Water is the recommended suppressant in case of a fire involving a lithium-ion battery and will not exacerbate a fire involving lithium-ion cells. Does Powerwall require additional venting to prevent the accumulation of flammable or explosive 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 ventilation. NEC: L480.9(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 mPasures 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 this technology. Is Powerwall's battery pack low voltage? Yes. The internal battery pack operates at less than 50 VDC nominal. Unlike legacy battery systems, Powerwall is a fully enclosed, factory-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. 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(B) • 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. Wiring Methods • All conduit and fittings properly installed per the respective article in Chapter 3 of the NEC. • Conduit is adequately secured and supported. 3xx.30 • Raceways containing insulated circuit conductors 4 AWG and larger are protected from abrasion by an identified fitting providing a smoothly rounded insulating surface. 300.4(G) • Residential Energy Storage equipment grounding conductor is identified as either bare, green, or green with continuous yellow stripe(s). 250.119 • Grounded conductor identified properly. 200.6(A), (B) Overcurrent Protection and Wire Sizing Conductors and OCPDs are adequately sized per Articles 240 and 310 unless modified by 690.9(A), 690.10(B), or L106.20J and L/06.211. Disconnecting Means • Disconnecting means are provided to disconnect the energy storage device from all ungrounded conductors of all sources. 690.15 and/or [706.7]. This requirement is met by the integrated disconnect switch. • Where the energy storage device output terminals are more than 1.5 m (5 ft) from the connected equipment, or where output circuits pass through a wall or partition,a disconnecting means and overcurrent protection shall be provided at the energy storage device end of the circuit. 690.71(H), [706.7(E)]. The Powerwall complies with both the letter and the intent of the NEC: o As previously mentioned, the Powerwall is an inherently current-limiting device that will not c. tri u e-auLt_curletits to the AC output circuit. It is important to note that the 2017 NEC has removed this overcurrent requirement altogether and clarified that the intent was to protect the DC curiduclurs of a conventional battery. o The integrated disconnect satisfies the requirement for the energy storage device and of the circuit. o If the integrated disconnect is not within sight of the connected equipment, the 2P/30A breaker installed at the point of connection is the additional disconnect required by 690.71(H)(4). Labeling • A sign that indicates the type and location of on-site optional power sources is placed at building utility service-entrance location. /05.10, L/06-111 • Equipment fed by multiple sources are marked to indicate all sources of supply. 705.12(D)(3). • Where the integrated disconnect and the 2P/30A breaker are not within sight, a plaque or directory shall be installed at each disconnect indicating the location of the other disconnecting means. 690.71(H)(5) or [706.7(E)(5)].

DNV GL—Document No.: 10075610-HOU-R-01-D, Issue: D, Status: Release v Page vii www.dnvgl.com DNV GL was contracted by Tesla Inc to perform testing on their Powerwall battery energy storage device, which is intended to be installed vertically on existing walls or structures at ground level. 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 : C ,O 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. 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.

Figure 2-1 Edge to edge spacing between units in test 1 Testing was conducted on 30 and 31 January 2018, with the first testing beginning just before 1100 EST. 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 ' ' ~ �.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 bo collect data as needed to support research and potential code exemption. As such, DNV GLmoved 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 Finecams 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 Powenma||s and the bottom of the roof. Finally, three regular cameras were used, with one placed in the front, one recording from the near, and a third installed to capture impact onthe soffit. 1-23 am 11 E1111,11 AW 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 _ GL-Document No.: 10075610-HOU-R-01-D, Issue: D, Status: Release Page -3 ` ' — �� ............ ` ......... ����L~�_'`-.��,�-__ � �, unit and sometimes aligned more into the soffit (when present). The gases sampled and their units of measure are shown below: Water Vapor (HZC\ 96) Carbon Dioxide (COZ, 96) Carbon Monoxide (CO, ppm) Nitrogen Monoxide (NO, ppm) Nitrogen Dioxide (NO2, ppm) Sulfur Dioxide (SOZ, ppm) Methane (CH4, ppm) Ethane (ppm) Ethy|ena (C2H4) Hydrogen Chloride (HC1, ppm) Hydrogen Fluoride (HF, ppm) Hydrogen Cyanide (HCN, ppm) Benzene (ppm) Toluene (ppm) Ethanol (ppm) Methanol (ppm) Propane (ppm) Oxygen (02, 96) In addition to the FTIR analyzer, Rescue Methods personnel near the test were equipped with MBA- brand foupgasana|yzecs 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 'Afa0l sect~ons Seven wall sections were built from common building types for installations perTos|a'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. VVa|| 1, with vinyl siding and poly foam insulation, was not used. The test order was not based on the wall number provided inthe 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 I rjn�'I t i a I'` 'uu t1h0 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. TEST PUESULTS AMD DATA ., est 1,.. Bgrick 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. Wall Thermocouples 600 Back Side of Wall 500 ..... ........: ... : .................

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.

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. 3.211' 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.

RiardEe board surface Test 3 was conducted on a wall sided and soffited by hardie board. 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 Back of Wall 350 _........................:....................... . ... ...... .. .. .... ..

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.

In Test 4, there was no roof or soffit and the FTIR probe was again placed directly above the device under test as opposed to tucked into the soffit.

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. This was done through frequent, short hose bursts into the roof, which can be seen in the brief DNV GL— Document No.: 10075610-HOU-R-01-D, Issue: D, Status: Release Page -20 www.dnvgl.com temperature drops in Figure 3-22. Ultimately, the fire load from the collapsing roof and vinyl siding proved sufficient to ignite the adjacent Powerwall, shown in Figure 3-23 through Figure 3-26. Given the delayed ignition between the conflagration of the first unit and the ignition of the second, it is likely that much of the heat responsible for the ignition came from the wall itself as opposed to the Powerwall. This suggests that spacing alone may not be sufficient for protection between two units adjacent to Vinyl sided building. Though spacing of several feet may be more effective, increasing spacing by 6-25 inches is unlikely to impact the results observed in this test.

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. DNV GL-Document No.: 10075610-HOU-R-01-D, Issue: D,Status: Release Page -28 www.dnvgl.com 4.1 EUlecthueness of hardle board in protedIng against fire spread Beyond validating the 10"spacing for limiting propagation, another takeaway from this project was the validation of the effectiveness of simple masonry products, such as hardie board, in greatly mitigating the spread of fire to flammable building materials. 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. .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 (Cl) 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 HCl 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, /et alone proper exhaust, should remove these gases and allow for unimpeded egress. 5 CONCLUSION! Testing was completed on six pairs of Powenwa||a 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, handie board, and likely any similar lightweight masonry product, may prove highly useful in protecting flammable exposure. In all but the vinyl aiding 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. blr�V�L--Document No.: 10075610-HOU-R-0 Issue: D, Status: Release Page -30 O , Driven by our purpose of safeguarding life, property and the environment, DNV GL enables organizations to advance the safety and sustainability of their business.

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.

Yes. Powerwall and the Gateway are listed to the applicable product standards by Intertek/ETL, an OSHA- approved Nationally Recognized Testing Laboratory (NRTL). See the table above for a partial list of certifications. If physical certificates are required, please email powerwall(cbtesla.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 wall-mounted? Powerwall weighs 276 lbs. and complies with seismic requirements when wall-mounted according to manufacturer's instructions. It has been evaluated to ICC 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 and/or breaker on the grid side. Water is the recommended suppressant in case of a fire involving a lithium-ion battery and will not exacerbate a fire involving lithium-ion cells. Does Powerwall require additional venting to prevent the accumulation of flammable or explosive 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 ventilation. 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 this technology. Is Powerwall's battery pack low voltage? Yes. The internal battery pack operates at less than 50 VDC nominal. Unlike legacy battery systems, Powerwall is a fully enclosed, factory-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 PommerxnaUrequire aseparate disconnect? No. Powerwall's onboard switch disconnects all ungrounded conductors and complies with Article 690.71 (2Ol4) and 7OG7 (2Ol7). NOTE: These articles require a second disconnecting means at the connected equipment when: ° Separated byawall orpartition, or * Input and output terminals are more than 5ftaway. This second disconnect will typically be the 2P/30A breaker installed at the point of connection. Can Powmrwa|| bminstalled outdoors? Yes. Povvenwa|| isaNEMA Type 3Renclosure and can boinstalled outdoors. What prevents Poxvemma|| from back-feeding the utility grid during apower outage? During a power outage, the Gateway automatically isolates the home from the grid per IEEE 1547. Povvervva|| and Gateway are both listed to UL 1741 because they are subject tothe same anti is|anding rules as a typical grid-interactive PV system. Gateway reconnects tothe grid once it is stable for at least minutes. What isthe maximum number ofcircuits that can bebacked upfor asingle Pmxxerwa||? 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 500OW, with a peak output capacity of 700OW for 10 seconds. The number of loads and circuits the customer wants backed up will determine the overall system size, including total number ofPnvvervva||s required. Is Powerwall required to be capable of backing up all the home's loads simultaneously? No. When Povvanwa|| is operating as a stand-alone system, as permitted in 705.40. available currant must be "equal to orgreater than the loadposed 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 E2014] and 7lO]5(A) [2Ol7]. When |nbackup mode, what happens |fthe load exceeds Powxe,xve||'srated output current? Povvervva|| automatically shuts down. Pnvvervva||'s inverter isan 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 ofPovvarvva||.
