The system involves electricity, and can be dangerous if installation personnel are not familiar with the appropriate safety procedures. Do not attempt to repair the Andalay Instant Connect with Enphase M215-IG Microinverter Module; it contains no user-serviceable parts. If it fails, please contact Andalay customer service to obtain an RMA number and start the replacement process. Tampering with or opening the Andalay Instant Connect Module or Enphase Micro-inverter will void the warranties. Connect the Andalay Instant Connect with Enphase M215-IG Microinverter to the electrical utility grid only after receiving prior approval from the utility company. Be aware that the body of the Micro-inverter is the heat sink and can reach a temperature of 80 C. To reduce risk of burns, do not touch. Do NOT disconnect the PV module from the Micro-inverter without first removing AC power. Do not strike the glass surface of the module with heavy or sharp objects or walk on surface. The glass surface may fracture thus disabling the function of the Andalay Instant Connect module and voiding the warranty. Artificially concentrated sunlight shall not be directed on the module. 5. INSTALLING ANDALAY-AX SERIES MODULES Andalay-AX series modules may be installed in various applications, which are particular to the roof type and are defined by the system designer, utilizing a variety of support structure options and attachment methods. Modules are commonly supported parallel to the surface of the building wall or roof. Module support structures that are used to support Andalay-AX series module(s) should be wind rated and approved for use in accordance with local and civil codes, prior to installation. For optimal performance in all applications, a minimum 2 in. clearance between the module frame and the mounting surface is required to allow cooler ambient air to circulate around the back of the module. Additionally, the module assembly is to be mounted over a fire resistant roof covering, rated for the application. If nonstandard mounting means are employed, the module Fire Class Rating may be affected. To attach the module to the roof mounting hardware, utilize 3/8" (9.5 mm) stainless steel G-bolt installed in the C-Channel of the module frame members and then through the support structure mounting hardware and secure with locking hex nuts. An applied torque of footpounds (27-33 Newton-meters) should be used to secure the G-bolt to the module frame. The specific number of attachment points should be appropriate for the roof type, local building code, wind, snow, and seismic loading conditions as defined by the system engineer. The distance between mounting points should not exceed 48 O.C. per horizontal row of modules and end modules in a string should not have more than 16 of the module unsupported. Figure 1 Figure 2 Row to row (North South) mechanical connections are to be completed using a N-S Module Mount as shown in figures 1&2. The C Channel engages with the bracket latch and is secured using 3/8" (9.5 mm) stainless steel G-bolts with locking hex nuts. Torque as specified above for roof mounting hardware.

3 6. BONDING Two threaded splices are used to create a bond path between interconnected modules. This inter-module bonding is achieved via the East-West sides. To ensure proper bonding between modules, each splice must be fully threaded into its adjacent panel and properly secured. To bond two modules, insert a splice through the hole on each end of one frame and begin threading each splice 1/2 turn in the frame rail (Figures 3&4). Position the adjacent panel so that the splices are aligned with the holes on each end of its frame. Slide the modules together until the splice threads can engage the frame threads on the adjacent panel. Tighten the splices to 5-7 ft-lbs. Inter-row bonding in the North-South direction is achieved via G-bolt assembly (Figure 2). The G-bolt replaces the need of grounding lug and copper wire in-between rows. 7. GROUNDING Figure 3 Figure 4 Proper grounding is achieved by assembling the module frame(s) contiguously using two bonding splices in the East-West direction. In the North-South direction, a stainless steel G-bolt secures to the frame by way of sharp edges is designed to cut through anodized coating. At the end of the array, the module frame is then attached to the grounding electrode, in accordance with Section 690 of the National Electrical Code (NEC) using one method as described below. Ensure positive electrical contact through the anodizing on the module's frame by attaching the grounding conductor to one of the diameter (4.4 mm) holes on the frame marked ground using an ILSCO GBL4-DBT lug, star-washer and thread-rolling X ½ Taptite II stainless steel screw using torque value 20 Lbf-in (Figure 5). Approved Wire Gauge: solid copper gauge AWG 4-12 Figure 5 Use solid copper gauge AWG 4-12 NOTE: The AC output neutral is not bonded to ground inside the Module. System grounding, if required by Sections and of the National Electric Code, ANSI/NFPA 70, is the responsibility of the installer. Page 3 of 6 Copyright Andalay Solar Inc. 2015

4 8. BYPASS DIODES All Andalay-AX series modules are supplied with factory installed (non user serviceable) bypass diodes. The purpose of bypass diodes is to provide a low-resistance current path around the shaded cells, thereby minimizing module heating and array current losses. The solar modules employ bypass diodes that have: Rated Average Forward Current [If (AV)] Above maximum system current at highest module operation temperature. Rated Repetitive Peak Reverse Voltage [Vrrm] Above maximum system voltage at lowest module operation temperature. 9. CONNECTING INSTANT CONNECT MODULE TO THE INTERCONNECT CABLE WARNING: DO NOT connect Andalay Instant Connect with Enphase M215-IG Microinverter to the utility grid or energize the AC circuit(s) until you have completed all of the installation procedures as described in the following sections. Andalay Instant Connect with Enphase M215-IG Microinverters are pre-wired and termination ready, for most attached or free standing building installations. Each module has a male and a female output connector (Figure 6). The male side of the branch is connected to an interconnect cable and is wired directly to the junction box at the head of the branch circuit. The female side of the branch is sealed with an Andalay End Cap. Figure 6 Front View of Module a. Andalay Instant Connect with Enphase M215-IG Microinverters is self-switching from 240 V and 208 V. Be sure to verify utility voltage, frequency, and whether utility is single or three phase and wire accordingly. AC Wiring Black - L1 Red - L2 White - Neutral Green - Ground b. As the modules are splice together, the male connector from one module will connect with the female connector of the adjacent module to form a continuous AC branch circuit. WARNING: Do NOT exceed the maximum number of Micro-inverters in an AC branch circuit, as displayed on the unit-rating label. Each Andalay Instant Connect Module AC branch circuit must be sourced from a dedicated branch circuit protected by a 20A maximum breaker. c. Install a protective end cap on any exposed female connectors. All exposed male connectors must be terminated in a junction box. Connect an interconnect cable to any exposed male connectors and wire directly to a junction box. WARNING: The male side connector is not touch safe and may be live when the system is energized by the utility system. Page 4 of 6 Copyright Andalay Solar Inc. 2015

5 NOTE: Be sure to size the AC wire gauge to account for voltage drop between the AC branch circuit junction box and the point of utility inter-connection. 10. COMMISSIONING 1. Turn ON the AC disconnects or circuit breaker on each AC branch circuit. Check the voltages on the Engage Cable to ensure proper wiring. WARNING: Verify proper AC cable voltage and neutral conductors prior to connecting to live voltage or connecting the connector to the AC string. Failure to properly connecting the wires can result in severe damage and void the warranty. 2. Turn OFF the AC disconnects or circuit breaker and connect the System Interconnect Harness to the string/branch. 3. Repeat for each string/branch until each one is complete. 4. Turn ON the main utility-grid AC circuit breaker. Your system will start producing power after a five-minute wait time. The Andalay Instant Connect with Enphase M215-IG Microinverter will start to send performance data over powerline to the Envoy. The time required for all the micro-inverters in the system to report to the Envoy will vary with the number of micro-inverters in the system. The first units should be detected within 15 minutes but the entire system could take hours to detect. Please refer to the Envoy Installation and Operation Manual for information on the Envoy. 11. OPERATION The Andalay Instant Connect with Enphase M215-IG Microinverter is powered on when sufficient dc voltage from the photovoltaic cells is applied. The status LED will flash green six times indicating proper start up. NOTE: In the event of a GFDI failure, the status LED will display continuous red after the fault occurs. This will persist when AC and DC power are cycled to the Micro-inverter. 12. MAINTENANCE Andalay Instant Connect with Enphase M215-IG Microinverter are designed for long life and require very little maintenance. Under most weather conditions, normal rainfall is sufficient to keep the module glass surface clean. If dirt build-up becomes excessive, clean the glass surface only with a soft cloth using mild detergent and water. USE CAUTION WHEN CLEANING THE BACK SURFACE OF THE MODULE TO AVOID PENETRATING BACK SHEET. Modules that are mounted at 15 or less should be cleaned more often, as they will not "self clean" as effectively. Once a year, have qualified service personnel check the general condition of the wiring and check to be sure that mounting hardware is tight. Loose connections may result in a damaged module or array. 13.
