Isolated DC Circuit Enables Integrated Ground System Grounding vs. Equipment Grounding To hilly understand PV system grounding, it is essential to first differentiate between system grounding and equipment grounding. System grounding requires a Grounding Electrode Conductor(GEC), which connects the current-carrying circuit to ground, including: • the negative or positive of a DC array • the neutral of a split single-phase AC system • the neutral of a bi-polar DC system Equipment grounding requires an Equipment Grounding Conductor (EGC), also known as bonding, which connects all non-current carrying metal parts to ground, including: • metal enclosures • racking • module frames With Enphase Microinverters, the EGC is bundled into the Engage Cable wiring system, which forms a ground connection with the enclosure of the microinverter. Plus, Enphase Microinverters with Integrated Ground do not require a GEC because the unit physically isolates the DC circuit within the microinverter from ground, thus meeting the NEC requirements for Ungrounded Photovoltaic Power Systems described under section 690.35. http://enphase.comlg rounding/ 1/3 Enphase Microinverters&Ungrounded PV Arrays Fully Integrated MiCroinverter System Ground Like the Enphase M190 and the previous-generation M215,the Enphase Microinverters with Integrated Ground are utility-interactive microinverters.All Enphase Microinverters use transformer coupling to isolate the DC and AC circuits.The major difference between the grounded and integrated ground models lies within the DC input stage of the microinverter,where DC power from the module enters the microinverter.Enphase Microinverters with Integrated Ground do not ground the DC input, as did their predecessors. By isolating the DC conductors from ground, Enphase Microinverters with Integrated Ground enable the installer to create an NEC-compliant Ungrounded PV Power System (690.35,690.41). With the Enphase Microinverters with Integrated Ground,the grounding requirement is satisfied with an EGG,so a GEC is not required.The EGC is provided through the Engage Cable system that has been certified and listed for this application. Unel AM Eft Line2 Neu tral _ ac-.- I ` r +DC AC Gf01 invert IM -DC 0 — Enphase I+dicroinverters with Integrated Ground: Ground Connections In previous models,the DC input was bonded to ground through a GFDI circuit.This essentially grounded the PV module's output.This construction required connection from this point to the grounding electrode using a GEC. However, since Enphase Microinverters with Integrated Ground isolate the DC conductors from ground, only a simpler EGG is required.The EGG is provided within the Engage Cable system, which connects seamlessly to the AC power system output of the microinverter. Enphase Microinverters with Integrated Ground detect ground faults in either the DC positive or negative conductor of the PV module by detecting the insulation resistance of each conductor to ground.Also new to Enphase Microinverters with Integrated Ground is the Insulation Monitor(IM),which measures the insulation resistance of the DC circuit with respect to ground.Together,these features offer greater safety than previously possible in any inverter technology.

January 2014 Enphase Microinverters&Ungrounded PV Arrays PV Grounding Terms Under NEC definitions in Article 100,two conductor types provide paths to ground.These are the Equipment Grounding Conductor(EGC)and the Grounding Electrode Conductor(GEC). Distinguishing between the EGC and the GEC is important when ensuring a photovoltaic array is code-compliant and safe.The following describes key terms from the NEC related to PV system grounding relevant to Enphase Microinverters. For reference,grounding requirements for microinverters are covered in UL1741 while grounding requirements for photovoltaic systems are covered in the NEC under Article 250 with amendments in Article 690.Always check with your jurisdiction for information about local amendments to the code. Underwriters Laboratory(UL)Standard 1741 grounding requirement: In Spring 2012, UL issued a document amending UL 1741 to address inverters for connection to ungrounded PV arrays. Enphase Microinverters with Integrated Ground have been successfully evaluated against this document.Therefore,a grounding electrode terminal for the attachment of a GEC is not required for this microinverter.Ali required grounding for Enphase Microinverters with Integrated Ground is met by the AC EGC supplied by the Engage Cable system and meets both NEC and UL requirements. National Electric Code grounding definitions: The Grounding Electrode System: Described more fully in NEC Article 250 Part III,the grounding electrode system provides a network of conductors,bus bars and bonding within a facility through which a direct connection to earth is established.The grounding electrode system is comprised of the equipment ground conductor,the grounded conductor,the grounding electrode conductor,and the grounding electrode. Grounding Electrode: Is a conducting object through which a direct connection to earth is established per the requirement outlined in NEC 250.52.Typical examples of a grounding electrode are a ground rod, buried metal pipe, plate electrode, concrete encased ground(UFER), and/or a ground ring. Equipment Grounding Conductor(EGC): Provides a conductive path to connect normally non- current-carrying metal parts of equipment together. EGCs are also found in traditional household wiring and connected to the rounded contact in a three-hole,grounded wall socket.The EGC is also used in the PV industry to connect all exposed metal parts such as PV module frame, racking structure,wiring enclosure(combiner and junction boxes), and the microinverter chassis. With Enphase Microinverters with Integrated Ground,the EGC is supplied through the Engage Cable system. Grounded Conductor:The NEC defines the grounded conductor as a current-carrying conductor that is intentionally grounded. Examples are the Neutral conductor found in an AC system or a grounded DC conductor found in many PV systems.The point at which the current- carrying conductor is connected to ground must be connected to the grounding electrode with a GEC. Grounding Electrode Conductor(GEC):The purpose of the GEC is to provide a conductive path to connect the common grounding point of the power system (AC or PV power systems)to the grounding electrode or to a grounding electrode system.AC or PV power system grounding is established when a current-carrying conductor is intentionally connected to ground by a GEC. 2 ©2014 Enphase Energy Inc.All rights reserved.

Thm 2008, 2011 and 2014 editions of the NEC allow for ungrounded PV arrays based on the provisions specified in NEC article 88U.35 Features • Integrated ground eliminates the need for a GEC: EnphameyNicminvertarm with Integrated Ground isolate the DC conductors from ground.This has the significant advantage of eliminating the need for o GEC connection between micnoinvurtem. • Ground fault detection on board: Enphomo K4|croinvertenowidh |nb*0naVed Ground offer advanced features to detect DC ground faults on either DC positive or negative conductors and always check the insulation resistance before exporting power.This eliminates the hidden ground faults that often go undetected with less mature microinverter technologies. • Smart disconnects:As on all Enphase Microinverters,the AC and DC connectors are rated and listed as disconnect devices under load per the NEC requirements.This simplifies design and eliminates the need for redundant and hend4o'|ocote disconnect devices. • Rvggedioed DC wiring: Each Enphase Microinverter with Integrated Ground is built with PV (Photovoltaic)Wire for all DC conductors. This provides double insulation for protection against wire damage and meets all wiring requirements of NEC 8QO.35.The PV module must also use PV Wire. 1 (9 2014 Enphase Energy Inc.All rights reserved- January 2014 BRIE .. ` • i Enphase Microinverters with Integrated Ground (I G) Enphase's latest generation microinverters feature Integrated (DC isolated)Ground. Because the DC circuit is isolated and insulated from ground,these microinverters do not require a Grounding Electrode Conductor(GEC)connected between each microinverter. This means you don't need to attach a separate copper grounding conductor to each microinverter or worry about a continuous run to ground. The result is faster installation with lower materials costs and a safer system. Integrated Ground and Code Requirements Solar installers must comply with the National Electrical Code(NEC)when installing Enphase Microinverters. Enphase Microinverters with Integrated Ground meet the requirements specified for Ungrounded PV Power Systems in sections 690.35 and 690.41 of the 2008, 201 land 2014 NEC. It also meets the Underwriters Laboratory(UL) Standard 1741 grounding requirements.

Enphase Microinverters ship with DC and AC cables and connectors.The DC connectors attach to the PV module,while the AC connector attaches directly to the Engager" Cable. It's that simple: no additional cabling is needed. About System Grounding Electrical code requires two types of grounding conductors: the Grounding Electrode Conductor(GEC), which is used between the grounding electrode and the point where a normally current carrying conductor is intentionally bonded to ground and the Equipment Grounding Conductor(EGC),which grounds non- current carrying metal parts of the system, such as the racking and module frames. Because Enphase Microinverters with Integrated Ground have DC integrated ground,they do not require a GEC. However electrical code still requires that exposed metal in the array be grounded (NEC 690.43 and 250.136(A)).This requirement is met for the microinverter because the ground conductor internal to the Engage Cable acts as the EGG. It may be met for racking and modules with use of an EGG or WEEBs to provide bonding to this ground system. ©2014 Enphase Energy Inc. All rights reserved. January 2014 NEC 2014—Enphase System Code Compliance NEC 2014 Section 705.12 Point of Connection Code Reference 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 requires exposed AC cable systems,such as the Enphase Engage Cable,to be protected by AC Arc-Fault Circuit Interrupter(AC AFCI)protection devices in the AC panel. Since Enphase Microinverters are utility-interactive inverters that backfeed into the electrical service through the overcurrent protection device, any overcurrent protection devices with AC AFCI that are installed must be specifically backfeed capable. NEC 2014 705.12(D) (4) Suitable for Backfeed. Circuit breakers, if backfed, shall be suitable for such operation. If terminals of circuit-breaker AFCIs are marked "Line"and"Load,"then the product is not backfeed capable. Today there are no known AC AFCI backfeed capable products in existence or planned, so Section 90.4 of the NEC code advises the inspector/AHJ to grant permission to use products that comply with the most recent previous edition of the Code. Until AC AFCI backfeed capable product is available, complying with NEC 2014 Section 705.12 (D) (6)is achieved by discretionary guidance per NEC 2014 Section 90.4 and referring to NEC 2011 Section 705.12,where AC Arc-Fault Circuit Protection is not a requirement for utility-interactive inverters. Cede Reference 90.4 Enforcement. This Code may require new products, constructions, or materials that may not vet be available at the time the Code is adopted. In such event, the authority havinq 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. NEC 2014 Section 690,11 ®C 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 do source circuits, do 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. 2 ©2014 Enphase Energy Inc.All rights reserved. March 2014 r NEC 2014 -® Enphase System Coda 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)for 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 this 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 PV system AC circuits or the grid. When the AC utility source is removed from the PV system AC 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. 1 ©2014 Enphase Energy Inc.All rights reserved. March 2014 _aDMHON%L FERMSAND(ONDI11Q\`, 7.

Loading Criteria 10 PSF=Dead Load roofing/framing • 40 PSF= Live Load (ground snow load) • 5 PSF= Dead Load solar panels/mounting hardware Total Dead Load=15 PSF The above values are within acceptable limits of recognized industry standards for similar structures. Analysis performed of the existing roof structure utilizing the above loading criteria indicates that the existing rafters will support the additional panel loading without damage, if installed correctly. C. Roof Structure Capacity 1. The photographs provided of the attic space and roof rafters show that the framing is in good condition with no visible signs of damage caused by prior overstressing. D. Solar Panel Anchorage 1. The solar panels shall be mounted in accordance with the most recent "ZEP Code Compliant Installation Manual', which can be found on the ZEP website (zepsolar.com). If during solar panel installation, the roof framing members appear unstable, deteriorated, structurally compromised or deflect non-uniformly, our office should be notified before proceeding with the installation. 2. Maximum allowable pullout per lag screw is 235 Ibs/inch of penetration as identified in the National Design Standards (NDS) of timber construction specifications for Hem-Fir(North Lumber) assumed. Based on our evaluation, the pullout value, utilizing a penetration depth of 2 '/2", is less than what is allowable per connection and therefore is adequate. Based on the variable factors for the existing roof framing and installation tolerances, using a thread depth of 2 '/2" with a minimum size of 5/16" lag screw per attachment point for panel anchor mounts should be adequate with a sufficient factor of safety. 3. Considering the roof slopes, the size, spacing, condition of roof, the panel supports shall be placed at and attached to no greater than every fourth roof rafter as panels are installed perpendicular across rafters and no greater than the panel length when installed parallel to the rafters (portrait). No panel supports spacing shall be greater than four(4) rafter spaces or 64"o/c, whichever is less. 4. Panel supports connections shall be staggered to distribute load to adjacent rafters. Based on the above evaluation, it is the opinion of this office that with appropriate panel anchors being utilized the roof system will adequately support the additional loading imposed by the solar panels. This evaluation is based on information supplied to us at the time of this report and current industry standards and practices.

Site Visit/Verification Form prepared by a Vivint Solar representative identifying specific site information including size and spacing of rafters for the existing roof structure. 2. Design drawings of the proposed system including a site plan, roof plan and connection details for the solar panels. This information was prepared by Vivint Solar and will be utilized for approval and construction of the proposed system. 3. Photovoltaic Rooftop Solar System Permit Submittal prepared by Vivint Solar identifying design parameters for the solar system. 4. Photographs of the interior and exterior of the roof system identifying existing structural members and their conditions. Based on the above information we have evaluated the structural capacity of the existing roof system to support the additional loads imposed by the solar panels and have the following comments related to our review and evaluation: Description of Residence: The existing residence is typical wood framing construction with the roof system consisting of 2 x 6 dimensional lumber at 16" on center with 2 x 4 collar ties every 48". The attic space is unfinished and photos indicate that there was free access to visually inspect the size and condition of the roof rafters. All wood material utilized for the roof system is assumed to be Spruce-Pine-Fir #2 or better with standard construction components. Our review of the photos of the exterior roof does not indicate any signs of settlement or misalignment caused by overstressed underlying members. Stability Evaluation: A. Wind Uplift Loading 1. Refer to attached ZEP calculations sheet for ASCE/SEI 7-10 Minimum Design Loads for Buildings and other Structures, wind speed of 100 mph based on Exposure Category "B" and 22 and 23 degree roof slopes on the dwelling areas. Ground snow load is 40 PSF for Exposure "B", Zone 4 per(ASCE/SEI 7-10). 2. Total area subject to wind uplift is calculated for the Interior, Edge and Corner Zones of the dwelling.
