NOTE: To ensure optimal reliabiIityand to meet warranty requi rem ents, the Enphase Microinvertermustbe installed according to the instructions in this manual. How the Enphase IQ Series Microinverters Work The Enphase Microinvertermaximizes energy production by using a sophisticated Maximum Power Point Tracking (MPPT) algorithm. Each Enphase Microinverterindividually connects to one PV module in your array. This configuration enables an individual MPPT to control each PV module, ensuring that maximum power available from each PV module is exported to the utility grid regardless of the performance of the other PV modules in the array. While an individual PV module in the array maybe affected by shading, soiling, orientation, or PVmodulemismatch, each Enphase Microinverterensures top performance for its associated PV module. Enphase IQ :....... Enphase lQ Enphase Gateway Battery I:� qpp i System Monitoring Once you install the Enphase IQ Gateway and provide an internet connection through a broadband router or modem, the Enphase IQ Microinverters automatically begin reporting to the Enphase Installer Platform. The Enphase Installer Platform presents currentand historical system performance trends and informs you ofPVsystem status. Optimal Reliability Microinverter systems are inherently more reliable than traditional inverters. The distributed nature of a m icroinverter system ensures thatthere is no single pointof system failure in the PV system. Enphase Microinverters are designed to operate at full powerat am bienttem peratures as high as 60°C (140°F). Ease of Design PV systems using Enphase Microinverters are very simple to design and install. You will not need string calculations orcum bersome traditional inverters. You can install individual PV modules in any combination of PV module quantity, type, age, and orientation. Each m icroinverter quickly mounts on the PV racking, directly beneath each PV module. Low voltage DC wires connect from the PV module directly to the co -located microinverter, eliminating the risk of personnel exposure to dangerously high DC voltage. 10 © 2022 Enphase Energy Inc.

Them icroinverter housing is designed for outdoor installation and complies with the NEMA250, type 6 environmental enclosure rating standard. NEMA 6 rating definition: indoor or outdoor use primarily to provide a degree of protection against hose -directed water, the entry of water during occasional temporary submersion at limited depth, and damage from external ice formation. The Enphase IQ Cable is available with connector spacing options to accommodate installation of PV modules in portrait or landscape orientation. For Enphase IQ Cable ordering information, see "Enphase IQ Cable Planning and Ordering" on page 28. Compatibility The Enphase IQ Series Microinverters are electrically compatible with PV modules as listed in the following table. For specifications, see "Technical Data" starting on page 30 of this manual. You can referto the Enphase Compatibility Calculatorat: enphase.com/en-us/support/module-compatibilitvto verify PV module electrical compatibility. To ensure mechanical compatibility, be sure to order the correct connector type for both microinverter and PV module from your distributor. WARNING: Risk of fire. The PV module DC conductors must be labeled "PV Wire" or "PV Cable" to comply with NECfor Ungrounded PV Power Systems.

Your Authority Having Jurisdiction (AHJ) may require you to bond the mounting bracketto the racking. If so, use UL2703 hardware orstar washers. The microinverteritself has Class II double -insulated rating, which includes ground fault protection (GFP). To support GFP, use only PV modules equipped with DC cables labeled PV Wire or PV Cable. Branch Circuit Capacity Plan your AC branch circuits to meetthe following lim its for maxim urn numberof m icroinverters per branch when protected with a 20 am p (maxim um) over current protection device (OCPD). Maximum* IQ8 Micros per AC branch circuit (240 VAC) Maximum* IQ8+ Micros per AC branch circuit (240 VAC) Maximum* IQ8M Micros per AC branch circuit (240 VAC) 16 13 11 Maximum* IQ8A Micros per AC branch circuit (240 VAC) Maximum* IQ8H Micros per AC branch circuit (240 VAC) Maximum* IQ8H Micros per AC branch circuit (208 VAC) 11 10 9 NOTE: *Limits may vary.

December2022 IQ8 / IQ8+ / IQ8M / IQ8A / IQ8H Micro Installation and Operation Utility Service Requirements The En phase IQ Series Microinverters work with single-phase service. Measure AC line voltages at the electrical utility connection to confirm that it is within the ranges shown: 240 Volt AC, Single Phase L1 to L2 211 to 264 VAC L1, L2 to ground 106to 132 VAC 208 Volt AC, Single Phase L1 to L2 183 to 229 VAC L1, L2 to ground 106to 132VAC NOTE: All 208 VAC installations require thatyou use the Enphase IQ Gateway to commission the Enphase Microinvertersto propagate correct grid profile settingsfor208 VAC trip points. Wire Lengths and Voltage Rise When planning the system, you mustselect the appropriate ACconductorsize to minimize voltage rise. Selectthe correct wire size based on the distance from the beginning of the microinverterAC branch circuitto the breakerin the load center. Enphase recommends a voltage rise total of less than 2% forthe sections from the m icroinverterAC branch circuit to the breakerin the load center. Enphase provides guidance aboutchoosing wire size and maximum conductor lengths in the Voltage Rise Technical Brief ateniphase.com/suppo Refer to this brief for voltage rise values in Enphase IQ Cables and on how to calculate voltage rise in other wire sections of the system. Standard guidelines forvoltage rise on feeder and AC branch circuit conductors might not be sufficientfor microinverterAC branch circuits that contain the maximum allowable microinverters. This is due to high inherent voltage rise on the AC branch circuit. Best practice: Center -feed the branch circuit to minimize voltage rise in a fully populated branch. This J practice greatly reduces the voltage rise as com pared with an end -fed branch. To center -feed a branch, t� divide the circuit into two sub -branch circuits protected by a single OCPD. Lightning and Surge Suppression Enphase Microinverters have integral surge protection, greater than most traditional inverters. However, if the surge has sufficient energy, the protection built into the m icroinverter can be exceeded, and the equipmentcan be damaged. Forthis reason, Enphase recom mends thatyou protect your system with a lightning and/or surge suppression device. In addition to having some level of surge suppression, it is also importantto have insurance that protects against lightning and electrical surges. Enphase has tested the following devices: • Leviton 51110-SRG • Schneider SauareD HEPD50 NOTE: Protection against lightning and resulting voltage surge must be in accordance with local standards. 12 © 2022 Enphase Energy Inc.

Enphase IQ Cable Planning and Ordering The Enphase IQ Cable is a continuous length of 12 AWG, double insulated, outdoor -rated cable with integrated connectors for microinverters.These connectors are preinstalled along the IQ Cable at intervals to accom modate varying PV module widths. The microinverters plug directly into the cable connectors. The cabling is compatible with a variety of PV racking systems. For a list of approved PV racking systems, referto the PV Racking Compatibility documenton the Enphase website at enphase.com/support. Connector Spacing Options IQ Cable is available in three connector spacing options. The gap between connectors on the cable can be 1.3 meters, 2.0 meters, or 2.3 meters. The 1.3 meterspacing is best suited for connecting PV modules installed in portrait orientation, while the 2.0 meter and 2.3 meter spacing allows you to install 60-cell and 72-cell PV modules in landscape orientation, respectively. Cabling Options Ordering options include: Cable Model Connector spacing PV module orientation Connector count per box Q-12-10-240 1.3 m (50") Portrait 240 Q-12-17-240 2.0 m (78") Landscape (60-cell) 240 Q-12-20-200 2.3 m (90") Landscape (72-cell) 200 The cabling system is flexible enough to adaptto almostany solar design. To determine the cable type you need, apply the following considerations: • When mixing PV modules in both portrait and landscape orientation, you may need to transition between cable types. See the preceding table foravailable cable types. • To transition between cable types, install a field wireable connector pair. • In situations where portrait modules are widely spaced, you may need to use landscape spaced cables forthe portrait -oriented PV modules and create loops of excess cable, if needed. !\ WARNING: Do not form loops smallerthan 12cm (4.75") in diameter Enphase IQ Cable Accessories The Enphase IQ Cable is available with several accessory options for ease of installation, including: • Field wireable connectors (male):(Q-CONN-1OM) Make connections from anyfield wireable female connector • Field wireable connectors (female): (Q-CONN-1 OF) Make connections from any IQ Cable open connectoror field wireable male connector • Cable clips: (Q-CLIP-100) Used to fasten cabling to the racking or to secure looped cabling 27 © 2022 Enphase Energy Inc.

Al rights reserved. December2022 IQ8 / IQ8+ / IQBM / IQBA / IQBH Micro Installation and Operation Technical Data Technical Considerations Be sure to apply the following when installing the En phase IQ8 Series Microinverter System: WARNING: Risk of equipment damage. You must match the DC operating voltage range of the PV 1 module with the allowable inputvoltage range of the En phase Microinverter. -• WARNING: Risk of equipment damage. Them axim um open circuit voltage of the PV module Umust not exceed the specified maximum input voltage of the Enphase Microinverter. PV modules must have conductors labeled "PV Wire" or "PV Cable" to comply with NEC for Ungrounded PV Power Systems. • Verify that the voltage and current specifications of the PV module match those of the microinverter. • The maximum shortcircuitcurrent rating of the PV module mustbe equal to or less than the maximum input DC short circuit current rating of them icroinverter. The output voltage and current of the PV module depend on the quantity, size and temperature of the PV cells, as well as the insolation on each cell. The highest PV module output voltage occurs when the temperature of the cells is the lowest and the PV module is at open circuit (not operating). Bifacial Modules Enphase Microinverters are compatible with bifacial PV modules. Bifacial solar modules produce power from both sides of a bifacial module, increasing total energy generation. The power gained from rear side (bifacial gain) is highly influenced byvarious design factors such as albedo, module elevation, pitch, temperature and shading. The bifacial gain can be anywhere between 0% to 30% of nominal rating (frontside power rating) of the module. Since the bifacial gain is highly influenced by various design considerations, pairing the bifacial module with right m icroinverter depends on the electrical characteristics of a given module. The temperature adjusted electrical parameters (maximum power, voltage and current) of the bifacial modules, considering the front side electrical parameters (i.e. 0% back side gain), must be within the microinverter input parameters range. See Step 3: Mount the Microinverters on page 15 fortips on vertical mounting of bifacial modules. 29 © 2022 Enphase Energy Inc. Al rights reserved.
