DATASHEETIQ8M and IQ8A MicroinvertersOur newest IQ8 Microinverters are the industry’s rst microgrid-forming, software dened microinverters with split-phase power conversion capability to convert DC power to AC power eciently. The brain of the semiconductor-based microinverter is our proprietary application specic integrated circuit (ASIC) which enables the microinverter to operate in grid-tied or o-grid modes. This chip is built in advanced 55nm technology with high speed digital logic and has superfast response times to changing loads and grid events, alleviating constraints on battery sizing for home energy systems.Easy to install• Lightweight and compact with plug-n-play connectors• Power Line Communication (PLC) between components• Faster installation with simple two-wire cablingHigh productivity and reliability• Produce power even when the grid is down*• More than one million cumulative hours of testing• Class II double-insulated enclosure• Optimized for the latest high-powered PV modulesMicrogrid-forming• Complies with the latest advanced grid support**• Remote automatic updates for the latest grid requirements• Congurable to support a wide range of grid proles• Meets CA Rule 21 (UL 1741-SA) and IEEE 1547:2018 (UL 1741-SB 3rd Ed.) Note: IQ8 Microinverters cannot be mixed together with previous generations of Enphase microinverters (IQ7 Series, IQ6 Series, etc) in the same system.© 2022 Enphase Energy. All rights reserved.

(1) Pairing PV modules with wattage above the limit may result in additional clipping losses. See the compatibility calculator at https://link.enphase.com/module-compatibility. (2)Nominal voltage range can be extended beyond nominal if required by the utility. (3) Limits may vary. Refer to local requirements to dene the number of microinverters per branch in your area.IQ8M and IQ8A MicroinvertersINPUT DATA (DC) IQ8M-72-2-US IQ8A-72-2-USCommonly used module pairings1 W 260 – 460 295 – 500Module compatibility 54-cell / 108 half-cell, 60-cell / 120 half-cell, 66-cell / 132 half-cell and 72-cell / 144 half-cellMPPT voltage range V 30 – 45 32 – 45Operating range V 16 – 58Min. / Max. start voltage V 22 / 58Max. input DC voltage V 60Max. continuous input DC current A 12Max. input DC short-circuit current A 25Max. module Isc A 20Overvoltage class DC port IIDC port backfeed current mA 0PV array conguration 1 x 1 Ungrounded array; No additional DC side protection required; AC side protection requires max 20A per branch circuitOUTPUT DATA (AC) IQ8M-72-2-US IQ8A-72-2-USPeak output power VA 330 366Max. continuous output power VA 325 349Nominal (L-L) voltage / range2 V 240 / 211 – 264Max. continuous output current A 1.35 1.45Nominal frequency Hz 60Extended frequency range Hz 47 – 68AC short circuit fault current over 3 cycles Arms2Max. units per 20 A (L-L) branch circuit311Total harmonic distortion <5%Overvoltage class AC port IIIAC port backfeed current mA 30Power factor setting 1.0Grid-tied power factor (adjustable) 0.85 leading – 0.85 laggingPeak eciency % 97.8 97.7CEC weighted eciency % 97.5 97Night-time power consumption mW 60MECHANICAL DATAAmbient temperature range -40°C to +60°C (-40°F to +140°F)Relative humidity range 4% to 100% (condensing)DC Connector type MC4Dimensions (H x W x D) 212 mm (8.3”) x 175 mm (6.9”) x 30.2 mm (1.2”)Weight 1.08 kg (2.38 lbs)Cooling Natural convection – no fansApproved for wet locations YesPollution degree PD3Enclosure Class II double-insulated, corrosion resistant polymeric enclosureEnviron. category / UV exposure rating NEMA Type 6 / outdoorCOMPLIANCECerticationsCA Rule 21 (UL 1741-SA), UL 62109-1, IEEE 1547:2018 (UL 1741-SB 3rd Ed.), FCC Part 15 Class B, ICES-0003 Class B, CAN / CSA-C22.2 NO. 107.1-01This product is UL Listed as PV Rapid Shutdown Equipment and conforms with NEC 2014, NEC 2017, and NEC 2020 section 690.12 and C22.1-2018 Rule 64-218 Rapid Shutdown of PV Systems, for AC and DC conductors, when installed according to manufacturer’s instructions.IQ8MA-12A-DS-0069-03-EN-US-2022-12-27
