Isolated DC Circuit Enables Integrated Ground System Grounding vs.Equipment Grounding To hilly understand PV system grounding, it is essential to fist 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. hKp:l/enphase.caNgrounding/ 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 EGC,so a GEC is not required.The EGC is provided through the Engage Cable system that has been certified and listed for this application. / linet Neutral ac EGC tOC RC GFOI Invert IM -DC Enphase Microinverters 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 EGC is required.The EGC 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.All 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(LIFER), 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 0 2014 Enphase Energy Inc.All rights reserved. January 2014 WHITE PAPER [ei enphase Enphase Microinverters and Ungrounded PV Arrays Enphase M250 and new M215 with Integrated Ground—no need for a separate GEC Overview Enphase has developed a new microinverter family that includes the M250 and new M215 with integrated (DC isolated)ground.Because the DC circuit is isolated and insulated from ground,these micminverters do not require a Grounding Electrode Conductor(GEC)connected between each microinverter.The Enphase Microinverters with Integrated Ground are compatible with most 60-cell PV modules(210W to 30OW STC or higher)and install quickly and easily.They work with either three-phase 208 VAC or single- phase 240 VAC services.Enphase Microinverters ship with integrated DC and AC cables and connectors.The DC connectors attach to the PV module,while the AC connector attaches to the EngageTM Cable. No additional cabling is needed. An ungrounded array,when coupled with sophisticated features of the Enphase Microinverters with Integrated Ground,offers greater safety for the installer,system owner,and maintenance personnel. In addition to enhancing safety,the integrated ground technology streamlines,simplifies,and economizes the installation process for installers and inspectors of all project types. This document clarifies solar grounding terminology and describes NEC(National Electrical Code) compliant grounding methods for Enphasee Microinverters with integrated(DC isolated)ground.The 2008,2011 and 2014 editions of the NEC allow for ungrounded PV arrays based on the provisions specified in NEC article 690.35. Features • Integrated ground eliminates the need for a GEC: Enphase Microinverters with Integrated Ground isolate the DC conductors from ground.This has the significant advantage of eliminating the need for a GEC connection between microinverters. • Ground fault detection on board: Enphase Microinverters with Integrated 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 hard-to-locate disconnect devices. • Ruggedized 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 690.35.The PV module must also use PV Wire. 1 0 2014 Enphase Energy Inc.All rights reserved. January 2014 TECHNICAL BRIEF [e] enphase i Enphase Microinverters with Integrated Ground (IG) 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 2006,2011 and 2014 NEC. It also meets the Underwriters Laboratory(UL)Standard 1741 grounding requirements. For further information, refer to the whitepaper on Enphase Microinverters and Ungrounded PV Arrays and other materials at www.enphase.com/Groundina, Identifying Microinverters - No grounding terminal with Integrated Ground - Installers and inspectors can easily Flat lid identify Enphase Microinverters with Integrated Ground. Installing Microinverters RcductlabN with Integrated Ground -w on bottom 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 Engage" 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 EGC. It may be met for racking and modules with use of an EGC or WEEBs to provide bonding to this ground system. ©2014 Enphase Energy Inc. All rights reserved.

With the advanced M215,the DC circuit is isolated and insulated from ground, so no Ground Electrode Conductor(GEC) is required for the microinverter.This further simplifies installation, enhances safety, and saves on labor and materials costs. The Enphase M215 integrates seamlessly with the Engage®Cable, the Envoy Communications Gateway`, and Enlighten®, Enphase's monitoring and analysis software.

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. Code 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 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. 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 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 0 2014 Enphase Energy Inc.All rights reserved. March 2014 TECHNICAL BRIEF [e], enphase 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)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 undemeath 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. t ©2014 Enphase Energy Inc.All rights reserved March 2014 To learn more about the Enphase Microinverter System, visit enphase.com enphase® [e] E N E R G Y Enphase Energy/Microinverter Product Family M250 vs. M215: Module Pairing Considerations There are instances where either the M250 or the M215 is an appropriate choice for pairing with a given module. For higher power 60-cell modules,the M250 is the logical choice. For lower rated modules, select the M215. However, for modules with STC output ratings between 25OW and 270W, there are several factors to weigh when deciding which microinverter to select for the application. MODULE O P 861000 2lj0W asM., 26dW and NOW Above 270W MICROINVERTER SELECTION M215 Installer prelerence M250 Factors to consider when pairing Local Mmperature:takes advantage of these gains cooler climates.result in higher module output and selecting the M25o with 25M—270W modules Modulo qudiq and peAbrmanw:not all modes are created equal.Even modules from diRerent brands with the same nameplate raft can often vary widely in actual DC output, given variance in manufacturing and quality assurance tasting standards.Keep module quality In mind when assessing expected output. Perspective on clipping:depending on the module brand selected and the installation location,an M215 can clip when paired with a module with an output rating above 25o1N. Depending on the Insialsr's calculations of the system's financial performance.such dipping loss can be either inconsequential or signiftcarnt when installing modules in the 25OW—27OW output range. A note about RMAs Starting in January 2014,Enphase will furnish the new M215 as a replacement unit for authorized merchandise returns mosived for the previous M215.Note that the new M215 unit does not require a GEC.Contact Enphase.com/support for assistance regarding returns.

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 and in accordance with the 2009 International Residential Code. 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 "Mounting System Inc. Installation Manual", which can be found on the Mounting System Inc. website (usa.mounting- systems.info/en/solar-mounting-systems-company). If during solar panel installation, the roof framing members appear unstable or deflect non-uniformly, our office should be notified before proceeding with the installation. 2. The solar panels are 1 1/2"thick and mounted 4 '/2'off the roof for a total height off the existing roof of 6". At no time will the panels be mounted higher that 6"above the existing plane of the roof. 3. Maximum allowable pullout per lag screw is 205 Ibs/inch of penetration as identified in the National Design Standards (NDS) of timber construction specifications for Spruce-Pine-Fir assumed. Based on our evaluation, the pullout value, utilizing a penetration depth of 2 1/2, is less than the maximum 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 1/2"with a minimum size of 5/16" lag screw per attachment point for panel anchor mount s will be adequate with a sufficient factor of safety. 4. 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. 5. Panel supports connections shall be staggered to distribute load to adjacent rafters. Based on the above evaluation, with appropriate panel anchors being utilized the roof system will adequately support the additional loading imposed by the solar panels. This evaluation is in conformance with the 2009 International Residential Code, current industry standards and practice, and based on information supplied to us at the time of this report.

Wyssling, PE Head of Structural Engineering scott.wysslingC@vivintsolar.com June 4, 2015 Mr. Dan Rock, Project Manager Vivint Solar 150 Padgette Street, Unit A Chicopee, MA 01022 Re: Structural Engineering Services Engebretson Residence 185 Spring Grove Ave, Florence MA S-4288108 3.38 kW System Dear Mr. Rock: Pursuant to your request, we have reviewed the following information regarding solar panel installation on the roof of the above referenced home: 1. 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 the Design Group and will be utilized for approval and construction of the proposed system. 3. Photovoltaic Rooftop Solar System Permit Submittal 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 2x6 dimensional lumber at 16" on center. The attic space is unfinished and the 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. The existing roofing material consists of composite asphalt shingles. 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 MSI calculations sheet for ASCE/SEI 7-10 Minimum Design Loads for Buildings and other Structures, wind speed of 90 mph based on Exposure Category "B" and 18, 23, & 45 degree roof slopes on the dwelling areas. Ground snow load is 40 PSF for Exposure "B", Zone 3 per(ASCE/SEI 7-10). 2. Total area subject to wind uplift is calculated for the Interior, Edge and Corner Zones of the dwelling. vivint.
