Those systems with unique characteristics may be handled with small additions to this Expedited Permit Process or may require much more information, depending on the uniqueness of the installation. The following pages contain forms for the Micro-Inverter to use with the Expedited Per- mit Process. The Standard String, AC Module, and Supply-Side Connection forms are also available as interactive PDF files at www.solarabcs.org/permitting. In jurisdic- tions that have adopted the Expedited Permit Process for PV Systems, these forms can be filled out electronically and submitted in either printed form and via email. An elec- tronic format is used so that the supplied information is standardized and legible for the local jurisdiction. 1338 1%2 N Custer St5/31/2024 Expedited Permit Process for PV Systems — Micro-Inverter 2 Expedited Permit Process for Small-Scale PV Systems Micro-Inverter The information in this guideline is intended to help local jurisdictions and contractors identify when PV system installations are simple, needing only a basic review, and when an installation is more complex. It is likely that 50%-75% of all residential systems will comply with these simple criteria. For projects that fail to meet the simple criteria, resolution steps have been suggested to provide as a path to permit approval. Required Information for Permit: 1. Site plan showing location of major components on the property. This drawing need not be exactly to scale, but it should represent relative location of components at site (see supplied example site plan). PV arrays on dwellings with a 3’ perimeter space at ridge and sides may not need separate fire service review. 2. Electrical diagram showing PV array configuration, wiring system, overcurrent protection, inverter, disconnects, required signs, and ac connection to building (see supplied standard electrical diagram). 3. Specification sheets and installation manuals (if available) for all manufactured components including, but not limited to, PV modules, inverter(s), combiner box, disconnects, and mounting system. Step 1: Structural Review of PV Array Mounting System Is the array to be mounted on a defined, permitted roof structure? l Yes l No If No due to non-compliant roof or a ground mount, submit completed worksheet for the structure WKS1. Roof Information: 1. Is the roofing type lightweight (Yes = composition, lightweight masonry, metal, etc…)__________________________ ____________________________________________________________________________________________________ If No, submit completed worksheet for roof structure WKS1 (No = heavy masonry, slate, etc…). 2. Does the roof have a single roof covering? l Yes l No If No, submit completed worksheet for roof structure WKS1. 3. Provide method and type of weatherproofing roof penetrations (e.g. flashing, caulk).____________________________ Mounting System Information: 1. Is the mounting structure an engineered product designed to mount PV modules with no more than an 18” gap beneath the module frames? l Yes l No If No, provide details of structural attachment certified by a design professional. 2. For manufactured mounting systems, fill out information on the mounting system below: a. Mounting System Manufacturer ___________Product Name and Model#________________________________ b. Total Weight of PV Modules and Rails ___________lbs c. Total Number of Attachment Points____________ d. Weight per Attachment Point (b÷c)_________________lbs (if greater than 45 lbs, see WKS1) e. Maximum Spacing Between Attachment Points on a Rail ______________inches (see product manual for maximum spacing allowed based on maximum design wind speed) f. Total Surface Area of PV Modules (square feet)_________________ ft2 g. Distributed Weight of PV Module on Roof (b÷f)_______________ lbs/ft2 If distributed weight of the PV system is greater than 5 lbs/ft2, see WKS1. Step 2: Electrical Review of PV System (Calculations for Electrical Diagram) In order for a PV system to be considered for an expedited permit process, the following must apply: 1. PV modules, utility-interactive inverters, and combiner boxes are identified for use in PV systems. 2. The PV array is composed of 4 series strings or less per inverter. 3. The total inverter capacity has a continuous ac power output 13,440 Watts or less 4. The ac interconnection point is on the load side of service disconnecting means (690.64(B)). 5. One of the standard electrical diagrams (E1.1, E1.1a, E1.1b, or E1.1c) can be used to accurately represent the PV system. Interactive PDF diagrams are available at www.solarabcs.org/permitting. Fill out the standard electrical diagram completely. A guide to the electrical diagram is provided to help the applicant understand each blank to fill in. If the electrical system is more complex than the standard electrical diagram can effectively communicate, provide an alternative diagram with appropriate detail. 1338 1%2 N Custer St5/31/2024 E x p e d i t e d P e r m i t P r o c e s s f o r P V S y s t e m s 3 Micro-Inverter Site Plan             1338 1%2 N Custer St5/31/2024 E x p e d i t e d P e r m i t P r o c e s s f o r P V S y s t e m s 4 Micro-Inverter Electrical Diagram Contractor Name, Address and Phone:One-Line Standard Electrical Diagram for Micro-Inverter PV Systems Site Name: Site Address: System AC Size: SIZE FSCM NO DWG NO REV E1.1a SCALE NTS Date: SHEET Drawn By: Checked By: DESCRIPTION OR CONDUCTOR TYPE USE-2 or PV WIRE GEC EGC X ALL THAT APPLY EXTERIOR CABLE LISTED W/ INV.

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. 1338 1%2 N Custer St5/31/2024 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 1338 1%2 N Custer St5/31/2024 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. 1338 1%2 N Custer St5/31/2024 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. 1338 1%2 N Custer St5/31/2024 1338 1%2 N Custer St5/31/2024 1338 1%2 N Custer St5/31/2024 1338 1%2 N Custer St5/31/2024 1338 1%2 N Custer St5/31/2024 Engineering Alliance, Inc https://www.eng-alliance.com 4603 April Meadow Way, Sugar Land, TX 77479.

The purpose of this report is to evaluate the physical fit of the connection between each racking system and the Unirac mounting products. SAMPLE DESCRIPTION Sample hardware of three systems was delivered to a 3rd party laboratory on April 27, 2017. Three racking systems, one manufactured by SnapNrack, one by IronRidge Inc, and one by Mounting Systems Inc were supplied along with three Unirac mounting systems, part #004CT5S, #004CT1S, and #004051D (previously Solarhooks part #KS-RH-CT5, #KS-RH-CT1, and #CMP-KT). Part#004AT1S is included thru similarity of mounting interface as well. The fit of Unirac’s Solarmount racking system and Quickmount QRail system (added thru similarity to Mounting Systems racking) was also evaluated by Unirac outside of the lab evaluations and is included in the results of this letter. Appendix A includes a specification sheet for each Unirac tile hook system. COMPATIBILITY PROCEDURE The three Unirac mounting systems products were assembled with each racking system using each racking system’s corresponding hardware. For example, the SnapNrack racking system was supplied with SnapNrack bolts and hardware; the connection of the SnapNRack racking system to the Unirac mounting system via the SnapNrack bolts and hardware was assessed. The same procedure was followed for the other systems. Each connection between the various racking systems and Unirac mounting systems was evaluated for fit and any limitations were noted. Appendix B includes photos of the racking systems assembled to the Unirac mounting systems. COMPATIBILITY RESULTS: Compatibility between the racking systems and Unirac mounting systems was evaluated for physical connection and fit. Unirac, SnapNrack, Iron Ridge, Mounting Systems and Quickmount QRail are all compatible with the evaluated Unirac mounting systems, as shown in Table 1, without limitation. This letter does not quantify the mechanical properties of the various racking systems or associated strength capacities of those systems. Engineering requirements set by building codes, engineering standards and local jurisdictions take precedence. Sincerely, Ernest Gallegos Director of Products Unirac, Inc.

Those systems with unique characteristics may be handled with small additions to this Expedited Permit Process or may require much more information, depending on the uniqueness of the installation. The following pages contain forms for the Micro-Inverter to use with the Expedited Per- mit Process. The Standard String, AC Module, and Supply-Side Connection forms are also available as interactive PDF files at www.solarabcs.org/permitting. In jurisdic- tions that have adopted the Expedited Permit Process for PV Systems, these forms can be filled out electronically and submitted in either printed form and via email. An elec- tronic format is used so that the supplied information is standardized and legible for the local jurisdiction. 1338 1%2 N Custer St5/31/2024 Expedited Permit Process for PV Systems — Micro-Inverter 2 Expedited Permit Process for Small-Scale PV Systems Micro-Inverter The information in this guideline is intended to help local jurisdictions and contractors identify when PV system installations are simple, needing only a basic review, and when an installation is more complex. It is likely that 50%-75% of all residential systems will comply with these simple criteria. For projects that fail to meet the simple criteria, resolution steps have been suggested to provide as a path to permit approval. Required Information for Permit: 1. Site plan showing location of major components on the property. This drawing need not be exactly to scale, but it should represent relative location of components at site (see supplied example site plan). PV arrays on dwellings with a 3’ perimeter space at ridge and sides may not need separate fire service review. 2. Electrical diagram showing PV array configuration, wiring system, overcurrent protection, inverter, disconnects, required signs, and ac connection to building (see supplied standard electrical diagram). 3. Specification sheets and installation manuals (if available) for all manufactured components including, but not limited to, PV modules, inverter(s), combiner box, disconnects, and mounting system. Step 1: Structural Review of PV Array Mounting System Is the array to be mounted on a defined, permitted roof structure? l Yes l No If No due to non-compliant roof or a ground mount, submit completed worksheet for the structure WKS1. Roof Information: 1. Is the roofing type lightweight (Yes = composition, lightweight masonry, metal, etc…)__________________________ ____________________________________________________________________________________________________ If No, submit completed worksheet for roof structure WKS1 (No = heavy masonry, slate, etc…). 2. Does the roof have a single roof covering? l Yes l No If No, submit completed worksheet for roof structure WKS1. 3. Provide method and type of weatherproofing roof penetrations (e.g. flashing, caulk).____________________________ Mounting System Information: 1. Is the mounting structure an engineered product designed to mount PV modules with no more than an 18” gap beneath the module frames? l Yes l No If No, provide details of structural attachment certified by a design professional. 2. For manufactured mounting systems, fill out information on the mounting system below: a. Mounting System Manufacturer ___________Product Name and Model#________________________________ b. Total Weight of PV Modules and Rails ___________lbs c. Total Number of Attachment Points____________ d. Weight per Attachment Point (b÷c)_________________lbs (if greater than 45 lbs, see WKS1) e. Maximum Spacing Between Attachment Points on a Rail ______________inches (see product manual for maximum spacing allowed based on maximum design wind speed) f. Total Surface Area of PV Modules (square feet)_________________ ft2 g. Distributed Weight of PV Module on Roof (b÷f)_______________ lbs/ft2 If distributed weight of the PV system is greater than 5 lbs/ft2, see WKS1. Step 2: Electrical Review of PV System (Calculations for Electrical Diagram) In order for a PV system to be considered for an expedited permit process, the following must apply: 1. PV modules, utility-interactive inverters, and combiner boxes are identified for use in PV systems. 2. The PV array is composed of 4 series strings or less per inverter. 3. The total inverter capacity has a continuous ac power output 13,440 Watts or less 4. The ac interconnection point is on the load side of service disconnecting means (690.64(B)). 5. One of the standard electrical diagrams (E1.1, E1.1a, E1.1b, or E1.1c) can be used to accurately represent the PV system. Interactive PDF diagrams are available at www.solarabcs.org/permitting. Fill out the standard electrical diagram completely. A guide to the electrical diagram is provided to help the applicant understand each blank to fill in. If the electrical system is more complex than the standard electrical diagram can effectively communicate, provide an alternative diagram with appropriate detail. 1338 1%2 N Custer St5/31/2024 E x p e d i t e d P e r m i t P r o c e s s f o r P V S y s t e m s 3 Micro-Inverter Site Plan             1338 1%2 N Custer St5/31/2024 E x p e d i t e d P e r m i t P r o c e s s f o r P V S y s t e m s 4 Micro-Inverter Electrical Diagram Contractor Name, Address and Phone:One-Line Standard Electrical Diagram for Micro-Inverter PV Systems Site Name: Site Address: System AC Size: SIZE FSCM NO DWG NO REV E1.1a SCALE NTS Date: SHEET Drawn By: Checked By: DESCRIPTION OR CONDUCTOR TYPE USE-2 or PV WIRE GEC EGC X ALL THAT APPLY EXTERIOR CABLE LISTED W/ INV.

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. 1338 1%2 N Custer St5/31/2024 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 1338 1%2 N Custer St5/31/2024 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. 1338 1%2 N Custer St5/31/2024 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. 1338 1%2 N Custer St5/31/2024 1338 1%2 N Custer St5/31/2024 1338 1%2 N Custer St5/31/2024 1338 1%2 N Custer St5/31/2024 1338 1%2 N Custer St5/31/2024 Engineering Alliance, Inc https://www.eng-alliance.com 4603 April Meadow Way, Sugar Land, TX 77479.

The purpose of this report is to evaluate the physical fit of the connection between each racking system and the Unirac mounting products. SAMPLE DESCRIPTION Sample hardware of three systems was delivered to a 3rd party laboratory on April 27, 2017. Three racking systems, one manufactured by SnapNrack, one by IronRidge Inc, and one by Mounting Systems Inc were supplied along with three Unirac mounting systems, part #004CT5S, #004CT1S, and #004051D (previously Solarhooks part #KS-RH-CT5, #KS-RH-CT1, and #CMP-KT). Part#004AT1S is included thru similarity of mounting interface as well. The fit of Unirac’s Solarmount racking system and Quickmount QRail system (added thru similarity to Mounting Systems racking) was also evaluated by Unirac outside of the lab evaluations and is included in the results of this letter. Appendix A includes a specification sheet for each Unirac tile hook system. COMPATIBILITY PROCEDURE The three Unirac mounting systems products were assembled with each racking system using each racking system’s corresponding hardware. For example, the SnapNrack racking system was supplied with SnapNrack bolts and hardware; the connection of the SnapNRack racking system to the Unirac mounting system via the SnapNrack bolts and hardware was assessed. The same procedure was followed for the other systems. Each connection between the various racking systems and Unirac mounting systems was evaluated for fit and any limitations were noted. Appendix B includes photos of the racking systems assembled to the Unirac mounting systems. COMPATIBILITY RESULTS: Compatibility between the racking systems and Unirac mounting systems was evaluated for physical connection and fit. Unirac, SnapNrack, Iron Ridge, Mounting Systems and Quickmount QRail are all compatible with the evaluated Unirac mounting systems, as shown in Table 1, without limitation.
