NEC 2014, Section 690.12 applies to PV conductors over 10 feet from the PV array and requires that the conductors power down to 30 volts and 240 volt-amperes within 10 seconds of rapid shutdown initiation. Enphase® Energy // Rapid Shutdown ® To learn more, visit enphase.com The 2014 edition of the National Electrical Code (NEC 2014) added new rapid shutdown requirements for PV systems installed on buildings. Enphase Microinverters fully meet rapid shutdown requirements in the new code without the need to install any additional electrical equipment. Enphase comes standard with rapid shutdown capability Residential Microinverter Commercial Microinverter All Enphase microin- verters, even those that were previously installed, inherently meet rapid shutdown requirements, no additional equipment or workarounds needed Enphase microinverters can safely shut down automatically, leaving only low-voltage DC electricity isolated to the PV module String inverters require work arounds for rapid shutdown Residential String Inverter Commercial String Inverter Work around.

January 2015 1 NEC 2014 — Enphase System Code Compliance Overview This technical brief discusses new NEC 2014 requirements that apply to Enphase Microinverter Systems. It is useful for installers, electricians, and electrical inspectors or authorities having jurisdiction (AHJs) in understanding how code-compliance is handled where NEC 2014 is adopted. Main topics discussed in this document are: • NEC 2014 Section 690.12 Rapid Shutdown of PV Systems on Buildings • NEC 2014 Section 705.12 Point of Connection • NEC 2014 Section 690.11 DC Arc-Fault Circuit Protection NEC 2014 Section 690.12 Rapid Shutdown of PV Systems on Buildings Enphase Microinverter Systems fully meet the rapid shutdown requirement without the need to install additional electrical equipment. Properly labeling the PV system power source and rapid shutdown ability is required per NEC Section 690.56 (B) and (C). Solar electric PV systems with Enphase Microinverters have one utility-interactive inverter directly underneath each solar module, converting low voltage DC to utility grid-compliant AC. When the utility grid is available and the sun is shining, each microinverter verifies that the utility grid is operating within the IEEE 1547 requirements. Only then does it export AC power into the electric service for use by loads onsite or export power to the utility grid for others to use. When the utility grid has a failure, or the PV system AC circuits are disconnected from the utility service via an AC breaker, AC disconnect, or removal of the solar or main utility service meter, the microinverters stop producing AC power in fewer than six AC cycles. Enphase Microinverters are not capable of operating as an AC voltage source. This means that without an AC utility source, Enphase Microinverters are not able to energize connected wiring and no AC voltage or current can be injected into the inverter output circuits or the grid. When the AC utility source is removed from the inverter output circuits via any means, such as an AC breaker, AC disconnect or removal of the solar or main utility service meter, this equipment performs the rapid shutdown function per 690.12. With an Enphase Microinverter System this shutdown occurs well within the 690.12 required 10 seconds, and there are no other conductors energized more than 1.5 m (5 ft) in length inside a building or more than 3 m (10 ft) from a PV array. Code Reference 690.12 Rapid Shutdown of PV Systems on Buildings. PV system circuits installed on or in buildings shall include a rapid shutdown function that controls specific conductors in accordance with 690.12(1) through (5) as follows. (1) Requirements for controlled conductors shall apply only to PV system conductors of more than 1.5 m (5 ft) in length inside a building, or more than 3 m (10 ft) from a PV array. (2) Controlled conductors shall be limited to not more than 30 volts and 240 volt-amperes within 10 seconds of rapid shutdown initiation. (3) Voltage and power shall be measured between any two conductors and between any conductor and ground. (4) The rapid shutdown initiation methods shall be labeled in accordance with 690.56(B). (5) Equipment that performs the rapid shutdown shall be listed and identified. NEC 2014 — Enphase System Code Compliance © 2015 Enphase Energy Inc. All rights reserved. January 2015 4 Three-Phase 208/120 Volt Services Solution: The compliance solution for systems interconnected to three-phase systems is to defer to NEC 90.4. There are no three-phase AC AFCI detection devices in existence. Until backfeed capable three- phase AC AFCI circuit breakers become generally available, an AHJ is permitted to refer to 90.4, i.e., the previous code edition, NEC 2011. Additionally, the NEC 210.12 code intention for any AC AFCI protection is for single-phase applications in dwellings or dormitory units and not meant for three-phase applications, example: Code Reference 210.12 Arc-Fault Circuit-Interrupter Protection. … 210.12(A) Dwelling Units. All 120-volt, single-phase, 15- and 20-ampere branch circuits….. 210.12(B) Branch Circuit Extensions or Modifications — Dwelling Units. … 210.12(C) Dormitory Units. All 120-volt, single-phase, 15- and 20-ampere branch circuits Although Chapter 7 applies to “Special Conditions,” the industry must be able to supply generally available equipment that is safe to use and meets the requirements for these special applications. For 705.12(D) (6) this is not the case for three-phase applications as there are no listed three-phase AC AFCI detection devices available. NEC 2014 Section 690.11 DC Arc-Fault Circuit Protection This requirement is for direct current (DC) Arc-Fault Circuit protection and only applies to systems with DC voltages above 80 VDC. Enphase Microinverter systems are exempted from this requirement as they always operate well below 80 VDC. The requirement is basically unchanged from the NEC 2011, and it is unnecessary to add DC AFCI to an Enphase Microinverter System installation. Code Reference 690.11 Arc-Fault Circuit Protection (Direct Current). Photovoltaic systems with dc source circuits, dc output circuits, or both, operating at a PV system maximum system voltage of 80 volts or greater, shall be protected by a listed (dc) arc-fault circuit interrupter, PV type, or other system components listed to provide equivalent protection. NEC 2014 — Enphase System Code Compliance © 2015 Enphase Energy Inc. All rights reserved. January 2015 2 NEC 2014 Section 705.12 Point of Connection (AC Arc-Fault Protection) In this section we explain how to comply with NEC 2014 Section 705.12 Point of Connection when installing Enphase Energy Systems with: • Supply Side Connection • Load-Side Connection to Single-Phase 120/240 Volt Services • Three-Phase 208/120 Volt Services Supply Side Connection Solution: No AC AFCI (Arc-Fault Circuit Interrupter) protection is required. Code Reference 705.12 Point of Connection The output of an interconnected electric power source shall be connected as specified in 705.12(A), (B), (C) or (D). Since the operator “OR” is used to define connection types, the code seems to intend that if one criteria is met, for example (A), the other criteria are not applicable. Code Reference 705.12(A) Supply Side. An electric power production source shall be permitted to be connected to the supply side of the service disconnecting means as permitted in 230.82(6). The sum of the ratings of all overcurrent devices connected to power production sources shall not exceed the rating of the service. 705.12(B) Integrated Electrical Systems. … 705.12(C) Greater Than 100 kW. … 705.12(D) Utility-Interactive Inverters. … 230.82(6) lists solar photovoltaic systems as eligible for equipment permitted to be connected to the supply side of the service disconnecting means. Since Enphase Energy Systems are solar photovoltaic systems, a supply side connection of an Enphase System may be accepted by AHJs to fully meet Code section 705.12. Since 705.12(A) requirements are met, it seems logical that the 705.12(D) requirements for connections to the load-side of the service disconnect means are not applicable. Load-Side Connection to Single-Phase 120/240 Volt Services Solution: Refer to section 90.4 and the previous code edition, NEC 2011. No listed backfeed capable AC AFCI solutions or acceptable equipment to enclose the cable harness exist. Until such products are generally available from manufacturers, when making load side connections, complying with NEC 2014 Section 705.12 (D) (6) is achieved by discretionary guidance per NEC 2014 Section 90.4. This means to refer to the previous code edition NEC 2011 Section 705.12, where AC Arc-Fault Circuit Protection is not a requirement for utility-interactive inverters. NEC 2014 Code Reference 705.12(D) Utility Interactive Inverters. The output of a utility-interactive inverter shall be permitted to be connected to the load side of the service disconnecting means of the other source(s) at any distribution equipment on the premises. Where distribution equipment, including switchgear, switchboards, or panelboards, is fed simultaneously by a primary source(s) of electricity and one or more utility-interactive inverters, and where this distribution equipment is NEC 2014 — Enphase System Code Compliance © 2015 Enphase Energy Inc. All rights reserved. January 2015 3 capable of supplying multiple branch circuits or feeders, or both, the interconnecting provisions for the utility-interactive inverter(s) shall comply with 705.12(D)(1) through (D)(6). 705.12 (D) (4) Suitable for Backfeed. Circuit breakers, if backfed, shall be suitable for such operation. 705.12(D)(6) Wire Harness and Exposed Cable Arc-Fault Protection. A utility-interactive inverter(s) that has a wire harness or cable output circuit rated 240 V, 30 amperes, or less, that is not installed within an enclosed raceway, shall be provided with listed ac AFCI protection. This NEC 2014 code section allows connection of an electric power source to the load side of service disconnect means and requires that the “interconnecting provisions for the utility-interactive inverter(s) shall comply with 705.12(D)(1) through (D)(6)”. Since the Enphase system contains one or more microinverters, which are the utility-interactive inverter(s), this section applies when connecting a system to the load side of a service disconnecting means. 705.12(D)(6) specifically requires that exposed AC cable systems, such as the Enphase Engage Cable, which is not feasibly run in enclosed raceway, to be protected by listed AC Arc-Fault Circuit Interrupter (AC AFCI) functionality. Given that utility-interactive inverters cannot operate without a utility service source, the location of the AC AFCI protecting the cable must logically be applied at the utility source side of the circuit. AC AFCI circuit breakers are the commonly available devices for single-phase branch circuits. No suitable for backfeed AC AFCI circuit breakers exist. Since Enphase Microinverters are utility-interactive inverters that backfeed into the electrical service through the overcurrent protection device, any AC AFCI circuit breakers must be specifically backfeed capable, per 705.12(D)(4). If terminals of circuit breaker AFCIs are marked “Line” and “Load,” then the AFCI product is not backfeed capable. No UL standard for backfeed testing exists for AC AFCI circuit breakers. Furthermore, 705.12(D)(6) requires that ac AFCI protection must be ”listed.” For a product or product category to become “listed,” a standard safety test procedure, such as a UL standard, must exist. The testing standard for AFCI circuit breakers is UL1699, which currently does not have provisions for testing this product category for backfeed applications. It is clear, that the code requirement is ahead of new product availability. Summary Until suitable for backfeed and listed AC AFCI circuit breakers become generally available, an AHJ is permitted to refer to 90.4, i.e., the previous code edition, NEC 2011. Code Reference 90.4 Enforcement. This Code may require new products, constructions, or materials that may not yet be available at the time the Code is adopted. In such event, the authority having jurisdiction may permit the use of the products, constructions, or materials that comply with the most recent previous edition of this Code adopted by the jurisdiction.  8431 Murphy Drive Middleton, WI 53562 USA Telephone: 608.836.4400 Facsimile: 608.831.9279 www.intertek.com                                                                                                   !

Recently, these fire resistance standards were expanded to include solar equipment as part of the roof system. Specifically, this requires the modules, mounting hardware and roof covering to be tested together as a system to ensure they achieve the same fire rating as the original roof covering. These new requirements are being adopted throughout the country in 2016. IronRidge Certification IronRidge was the first company to receive a Class A Fire Rating—the highest possible rating—from Intertek Group plc., a Nationally Recognized Testing Laboratory. IronRidge Flush Mount and Tilt Mount Systems were tested on sloped and flat roofs in accordance with the new UL 1703 & UL 2703 test standards. The testing evaluated the system’s ability to resist flame spread, burning material and structural damage to the roof. Refer to the table below to determine the requirements for achieving a Class A Fire Rating on your next project. Test Setup Solar Modules Solar modules are given a Type classification based on their materials and construction. Mounting System Mounting is tested as part of a system that includes type-tested modules and fire-rated roof covering. Roof Covering Roof covering products are given a Fire Class Rating of A, B or C based on their tested fire resistance. A burning wooden block is placed on module as a fan blows at 12 mph. Flame cannot be seen on underside of roof within 90 minutes. Burning Brand Test Flame at southern edge of roof is aimed up the roof as a fan blows at 12 mph. The flame cannot spread 6 feet or more in 10 minutes. Spread of Flame Test Fire Testing Process System Roof Slope Module Fire Rating* Flush Mount Any Slope Type 1, 2, & 3 Class A Tilt Mount ≤ 6 Degrees Type 1, 2, & 3 Class A *Class A rated PV systems can be installed on Class A, B, and C roofs.

Go to IronRidge.com Engineering Certification Letters We offer complete engineering resources and pre-stamped certification letters. Go to IronRidge.com Frequently Asked Questions What is a “module type”? The new UL1703 standard introduces the concept of a PV module type, based on 4 construction parameters and 2 fire performance parameters. The purpose of this classification is to certify mounting systems without needing to test it with every module. What roofing materials are covered? All fire rated roofing materials are covered within this certification including composition shingle, clay and cement tile, metal, and membrane roofs. What if I have a Class C roof, but the jurisdiction now requires Class A or B? Generally, older roofs will typically be “grandfathered in”, and will not require re-roofing. However, if 50% or more of the roofing material is replaced for the solar installation the code requirement will be enforced. Where is the new fire rating requirement code listed? 2012 IBC: 1509.7.2 Fire classification. Rooftop mounted photovoltaic systems shall have the same fire classification as the roof assembly required by Section 1505. Where is a Class A Fire Rating required? The general requirement for roofing systems in the IBC refers to a Class C fire rating. Class A or B is required for areas such as Wildland Urban Interface areas (WUI) and for very high fire severity areas. Many of these areas are found throughout the western United States. California has the most Class A and B roof fire rating requirements, due to wild fire concerns. Are standard mid clamps covered? Mid clamps and end clamps are considered part of the PV “system”, and are covered in the certification. What attachments and flashings are deemed compatible with Class A? Attachments and their respective flashings are not constituents of the rating at this time. All code-compliant flashing methods are acceptable from a fire rating standpoint. What mounting height is acceptable? UL fire testing was performed with a gap of 5”, which is considered worst case in the standard. Therefore, the rating is applicable to any module to roof gap. Am I required to install skirting to meet the fire code? No, IronRidge achieved a Class A fire rating without any additional racking components. What determines Fire Classification? Fire Classification refers to a fire-resistance rating system for roof covering materials based on their ability to withstand fire exposure. Class A - effective against severe fire exposure Class B - effective against moderate fire exposure Class C - effective against light fire exposure What if the roof covering is not Class A rated? The IronRidge Class A rating will not diminish the fire rating of the roof, whether Class A, B, or C. What tilts is the tilt mount system fire rated for? The tilt mount system is rated for 1 degrees and up and any roof to module gap, or mounting height. /lam IRONRIDGE ITEM NO.

XR Flush Mount System Certification - Rev B - 1 28357 Industrial Blvd. Hayward, CA 94545 1-800-227-9523 IronRidge.com Re: Report #7.16 XR10: Engineering Certification and Span Tables for the IronRidge XR10 Rail Flush Mount System, for Gable and Hip Roofs, Rev B. This report addresses the structural performance and code compliance of IronRidge’s XR Rail Flush Mount System. The contents of the report shall be reviewed in its entirety before application to any project design. The XR Rail Flush Mount System is a proprietary rooftop mounting system used to support photovoltaic (PV) modules installed in portrait or landscape orientation and set parallel to the underlying roof surface. PV modules are supported by extruded aluminum XR Rails and secured to the rails with IronRidge mounting clamps. The XR Rails are side mounted to a roof attachment with 3/8” stainless steel bonding hardware and the attachment is secured directly to the underlying roof structure. Assembly details of a typical XR Rail Flush Mount System installation and its core components are shown in Exhibit EX-0015. The IronRidge XR Rail Flush Mount System is designed and certified to the structural requirements of the reference standards listed below, for the load conditions and configurations tabulated in the attached span tables. • Minimum Design Loads for Buildings and Other Structures, ASCE/SEI 7-16 • SEAOC (Structural Engineers Association of California) report PV2-2017 Wind Design for Solar Arrays • AC428, Acceptance Criteria for Modular Framing Systems Used to Support Photovoltaic (PV) Panels, November 1, 2012 by ICC-ES • Aluminum Design Manual (ADM) 2015/2020, by the Aluminum Association, Inc. The span tables provided in this report are certified based on the structural performance of IronRidge XR Rails only with no consideration of the structural adequacy of the chosen roof attachments, PV modules, or the underlying roof supporting members. It is the responsibility of the installer or system designer to verify the structural capacity and adequacy of the aforementioned system components in regards to the applied or resultant loads of any chosen array configuration. This report certifies the IronRidge products referenced within this document and provides no determination of the project specific conditions including site loads, building profile, & roof zones, which remain the responsibility of the installer or system designer. The span tables included in this report provide the maximum allowable spans of XR Rail Flush Mount System for the respective loads and configurations listed, covering wind exposure categories B, C, & D, roof zones provided in ASCE 7 for enclosed and partially enclosed gable & hip roof profiles with roof slopes of 8° to 60°. The tabulated spans are applicable when the following conditions are met: A. Span is the distance between two adjacent attachment points and is to be measured with respect to the center of the attachment fastener. B. Each module shall be supported by 2 rails (2 rail system) or 3 rails (3 rail system). Spans are calculated based on 2 rail systems and are conservatively deemed applicable for 3 rail systems. C. The underlying roof slope, measured between the roof surface and horizontal plane, is 8º to 60º. D. The mean roof height, defined as the average of the roof eave height and the roof ridge height measured from grade for roofs with pitches above 10 degrees and defined as the eave height for roofs with pitches less than or equal to 10 degrees, does not exceed 30 feet. © 2024 IronRidge, Inc. XR Flush Mount System Certification - Rev B - 2 28357 Industrial Blvd. Hayward, CA 94545 1-800-227-9523 IronRidge.com E. A clearance from the underside of the array to the roof surface of 2” minimum shall be provided and the height of the array, the distance from the module top surface to the roof surface (defined as h2), shall not exceed 10”. F. Module length and area shall not exceed the maximum values listed on the respective span tables. The maximum module length within the scope of this report is 98.5 inches. The maximum module length specified within ASCE 7-16 is 80.4 inches. Wind pressure loads used to generate the span tables for modules with lengths above this value are based on the wind tunnel study “Wind Loads on photovoltaic arrays mounted on sloped roofs of low-rise building, parallel to the roof surface.” referenced in ASCE 7 Section C29.4.4. G. All Flush Mount components shall be installed in a professional workmanlike manner per IronRidge’s Flush Mount Installation Manual and other applicable standards for the general roof construction. The parameters and adjustments allowed in the span tables are defined as the following: 1. The Flush Mount System is designed as a Risk Category II structure as defined by ASCE 7-16 Table 1.5-1. 2. Wind speed shall conform to ASCE 7-16 Fig. 26.5-1B (for Risk Category II) and applicable state & local county/city amendments to the IBC. No special wind topographic features are included and both topographic coefficient (Kzt) and wind ground elevation factor (Ke) are taken as 1.0. 3. Snow load used in the span tables is the ground snow and shall conform to ASCE 7-16 Fig. 7.2-1 and applicable state & local county/city amendments to the IBC. If the local jurisdiction specified snow load is in the format of a flat roof snow, it shall first be converted to a ground snow following the local building code/ amendments before the application of the attached span tables. 4. No special snow conditions are considered including unbalanced, drifting, sliding, retention, or ponding snow. No rain-on-snow surcharge load is considered. The span tables do not apply to buildings which are intentionally kept below freezing, kept just above freezing, or unheated without first converting the snow load based on the difference in Thermal Factor and snow sliding. The Thermal Factor, Ct, is assumed to be 1.0, the roof exposure factor is assumed to be 1.0, and the Sliding Factor is based on ASCE 7-16 Figure 7.4-1 for a warm roof with unobstructed slippery surfaces. 5. The span tables reflect the ASCE 7 prescribed earthquake loads with the maximum magnitudes being: a) For ground snow no greater than 42psf: S s ≤ 2.0g for Site Class A, B, C, & D. b) For ground snow greater than 65psf: S s ≤ 1.0g for Site Class A, B, C, & D. c) For ground snow between 42 and 65psf: S s ≤ 1.5g for Site Class A, B, C, & D. 6. Roof zones are defined by ASCE 7-16 Figure 30.3-2B to Figure 30.3-2I and are organized into three groups in which the zones are assumed to share the same External Pressure Coefficients (GCp). Roof zones comprising each group along with each roof zone’s size and location to be used with the spans in this report are depicted in Figures 2 and 3 below each span table. 7. The maximum rail cantilever length, measured from the rail end to the nearest attachment point, shall be the lesser of the following two conditions: 40% of the allowable span provided for the respective load & configuration condition from the span tables, or 36”. © 2024 IronRidge, Inc. XR Flush Mount System Certification - Rev B - 3 28357 Industrial Blvd. Hayward, CA 94545 1-800-227-9523 IronRidge.com 8. Allowable span length in the charts may be multiplied by a factor of 1.08 if the rails are continuous over a minimum of three spans. This factor may not be used in determining maximum cantilever length. 9. No splices are allowed in the rail cantilever. For each XR splice type install per the following requirements: a) XR Bonded Splice cannot be installed in the center 1/3 of interior spans, or the outer 2/3 of end spans. b) BOSS Splice can be installed at any location within a span. 10. Shaded cells of the span tables indicate conditions in which UFO Mid Clamp connection capacity is exceeded if such conditions are encountered contact techsupport@ironridge.com. 11. Systems using CAMO module clamps shall be installed with the following guidance: a) For single module installations (orphan modules), CAMO clamps shall not be installed in regions that experience ground snow loads in exceedance of what is listed in the following table. Such scenarios are shown by asterisks in the applicable span tables. b) CAMO will function within a module’s design load ratings. Be sure the specific module being used with CAMO meets the dimensional requirements shown in the figure below and that the module selected is suitable for the environmental conditions of a particular project.

The maximum allowable span for Exposed or Edge modules shall be the lesser of the following two: 1. The span value for the Exposed or Edge module condition. 2. The span value determined by site wind speed and ground snow load. The allowable spans and cantilever shall only be applied to the portion of rail directly under Exposed or Edge Modules. Additionally, the shaded cells for the Exposed and Edge module conditions indicate conditions in which UFO Mid Clamp connection capacity is exceeded.

All rights reserved.August 2024 TEB-00153-2.0-EN Introduction IQ Battery 5P has a new battery module design to reduce thermal runaway between battery cells. The new design was evaluated for UL 9540A edition 4. This test was performed using the UL 9540A standard as written without using UL Certification Requirements Decisions (CRDs). The testing was done in an NFPA 286 fire test room, where gas composition was measured by Fourier transform infrared (FTIR) gas analyzers as defined in the standard. The results of the test allow the IQ Battery 5P unit with part number mentioned in Table 1: Part number identifier to be installed in non-habitable indoor or outdoor locations with a minimum room size (MRS) greater than 3 m3 based on 25% lower flammability limit (LFL) calculations. Unit test configuration The minimum spacing between the wall-mounted units was 3 inches horizontal and 6 inches vertical. The floor-mounted units were mounted on the floor at 8 inches from the wall-mounted units. The following figure illustrates the layout of the test. Figure 1: Reduced spacing layout for UL 9540A testing NOTE: Some battery units are not drawn to scale. These smaller battery units also represent an IQ Battery 5P unit.
