DATA SHEET <br />IQ8M and IQ8A Microinverters <br />Our newest IQ8 Microinverters are the industry’s first microgrid-forming, software defined <br />microinverters with split-phase power conversion capability to convert DC power to AC <br />power efficiently. The brain of the semiconductor-based microinverter is our proprietary <br />application specific integrated circuit (ASIC) which enables the microinverter to operate in <br />grid-tied or off-grid modes. This chip is built in advanced 55nm technology with high speed <br />digital logic and has superfast response times to changing loads and grid events, alleviating <br />constraints on battery sizing for home energy systems. <br />Easy to install <br />• Lightweight and compact with plug-n- <br />play connectors <br />• Power Line Communication (PLC) <br />between components <br />• Faster installation with simple two-wire <br />cabling <br />High productivity and reliability <br />• Produce power even when the grid is <br />down* <br />• More than one million cumulative hours <br />of testing <br />• Class II double-insulated enclosure <br />• Optimized for the latest high-powered <br />PV modules <br />Microgrid-forming <br />• Complies with the latest advanced grid <br />support** <br />• Remote automatic updates for the <br />latest grid requirements <br />• Configurable to support a wide range <br />of grid profiles <br />• Meets CA Rule 21 (UL 1741-SA) and IEEE <br />1547:2018 (UL 1741-SB) <br />Note: <br />IQ8 Microinverters cannot be mixed together with <br />previous generations of Enphase microinverters (IQ7 <br />Series, IQ6 Series, etc) in the same system. <br />© 2022 Enphase Energy.

Data subject to change. <br />*Only when installed with IQ System Controller 2, meets UL 1741. <br />**IQ8M and IQ8A support split-phase, 240V installations only. <br />Part of the Enphase Energy System, IQ8 <br />Series Microinverters integrate with the <br />IQ Battery, IQ Gateway, and the Enphase <br />App monitoring and analysis software. <br />IQ8 Series Microinverters redefine <br />reliability standards with more than one <br />million cumulative hours of power-on <br />testing, enabling an industry-leading <br />limited warranty of up to 25 years. <br />Connect PV modules quickly and easily <br />to IQ8 Series Microinverters using the <br />included Q-DCC-2 adapter cable with <br />plug-n-play MC4 connectors. <br />IQ8 Series Microinverters are UL listed <br />as PV Rapid Shutdown Equipment and <br />conform with various regulations, when <br />installed according to manufacturer’s <br />instructions. <br />IQ8MA-12A-DS-0069-02-EN-US-2022-12-02 <br />(1) Pairing PV modules with wattage above the limit may result in additional clipping losses. See the compatibility calculator at <br />https://link.enphase.com/module-compatibility. (2) Nominal voltage range can be extended beyond nominal if required by the <br />utility. (3) Limits may vary. Refer to local requirements to define the number of microinverters per branch in your area. <br />IQ8M and IQ8A Microinverters <br />IQ8M-72-2-US IQ8A-72-2-US <br />W 260 – 460 295 – 500 <br />V <br />54-cell / 108 half-cell, 60-cell / 120 half-cell, 66-cell / 132 half-cell and 72-cell / 144 half-cell <br />30 – 45 32 – 45 <br />V 16 – 58 <br />V 22 / 58 <br />V 60 <br />A 12 <br />A 25 <br />A 20 <br />II <br />mA 0 <br />1 x 1 Ungrounded array; No additional DC side protection required; AC side protection requires max 20A per branch circuit <br />IQ8M-72-2-US IQ8A-72-2-US <br />VA 330 366 <br />VA 325 349 <br />V 240 / 211 – 264 <br />A 1.35 1.45 <br />Hz 60 <br />Hz 47 – 68 <br /> Arms 2 <br />11 <br /><5% <br />III <br />mA 30 <br />1.0 <br />0.85 leading – 0.85 lagging <br />%97.8 97.7 <br />%97.5 97 <br />mW 60 <br />-40°C to +60°C (-40°F to +140°F) <br />4% to 100% (condensing) <br />MC4 <br />212 mm (8.3”) x 175 mm (6.9”) x 30.2 mm (1.2”) <br />1.08 kg (2.38 lbs) <br />Natural convection – no fans <br />Yes <br />PD3 <br />Class II double-insulated, corrosion resistant polymeric enclosure <br />NEMA Type 6 / outdoor <br />INPUT DATA (DC) <br />Commonly used module pairings1 <br />Module compatibility <br />MPPT voltage range <br />Operating range <br />Min. / Max. start voltage <br />Max. input DC voltage <br />Max. continuous input DC current <br />Max. input DC short-circuit current <br />Max. module Isc <br />Overvoltage class DC port <br />DC port backfeed current <br />PV array configuration <br />OUTPUT DATA (AC) <br />Peak output power <br />Max. continuous output power <br />Nominal (L-L) voltage / range2 <br />Max. continuous output current <br />Nominal frequency <br />Extended frequency range <br />AC short circuit fault current over <br />3 cycles <br />Max. units per 20 A (L-L) branch circuit3 <br />Total harmonic distortion <br />Overvoltage class AC port <br />AC port backfeed current <br />Power factor setting <br />Grid-tied power factor (adjustable) <br />Peak efficiency <br />CEC weighted efficiency <br />Night-time power consumption <br />MECHANICAL DATA <br />Ambient temperature range <br />Relative humidity range <br />DC Connector type <br />Dimensions (H x W x D) <br />Weight <br />Cooling <br />Approved for wet locations <br />Pollution degree <br />Enclosure <br />Environ. category / UV exposure rating <br />COMPLIANCE <br />Certifications <br />CA Rule 21 (UL 1741-SA), UL 62109-1, IEEE 1547:2018 (UL 1741-SB), FCC Part 15 Class B, ICES-0003 Class B, CAN / CSA-C22.2 NO. 107.1-01 <br />This product is UL Listed as PV Rapid Shutdown Equipment and conforms with NEC 2014, NEC 2017, and NEC 2020 section 690.12 and C22.1- <br />2018 Rule 64-218 Rapid Shutdown of PV Systems, for AC and DC conductors, when installed according to manufacturer’s instructions. <br />IQ8MA-12A-DS-0069-02-EN-US-2022-12-02 <br />941 W Alton Ave - <br />2017966906/27/23
