DATA SHEET <br />IQ8 and IQ8+ 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 3rd Ed.) <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 />**IQ8 and IQ8Plus 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 />IQ8SP-12A-DS-0067-03-EN-US-2022-12-27 <br />(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. <br />(2) Nominal voltage range can be extended beyond nominal if required by the utility. (3) Limits may vary. Refer to local requirements to define the number of microinverters per <br />branch in your area. <br />IQ8 and IQ8+ Microinverters <br />INPUT DATA (DC) IQ 8-60-2-US IQ8PLUS -72-2-US <br />Commonly used module pairings1 W 235 – 350 235 – 440 <br />Module compatibility 60-cell / 120 half-cell 54-cell / 108 half-cell, 60-cell / 120 half-cell, 66-cell / 132 half- <br />cell and 72-cell / 144 half-cell <br />MPPT voltage range V 27 – 37 27 – 45 <br />Operating range V 16 – 48 16 – 58 <br />Min. / Max. start voltage V 22 / 48 22 / 58 <br />Max. input DC voltage V 50 60 <br />Max. continuous input DC current A 10 12 <br />Max. input DC short-circuit current A 25 <br />Max. module Isc A 20 <br />Overvoltage class DC port II <br />DC port backfeed current mA 0 <br />PV array configuration 1 x 1 Ungrounded array; No additional DC side protection required; AC side protection requires max 20A per branch circuit <br />OUTPUT DATA (AC) IQ 8-60-2-US IQ8PLUS -72-2-US <br />Peak output power VA 245 300 <br />Max. continuous output power VA 240 290 <br />Nominal (L-L) voltage / range2 V 240 / 211 – 264 <br />Max. continuous output current A 1.0 1.21 <br />Nominal frequency Hz 60 <br />Extended frequency range Hz 47 – 68 <br />AC short circuit fault current over <br />3 cycles Arms 2 <br />Max. units per 20 A (L-L) branch circuit3 16 13 <br />Total harmonic distortion <5% <br />Overvoltage class AC port III <br />AC port backfeed current mA 30 <br />Power factor setting 1.0 <br />Grid-tied power factor (adjustable) 0.85 leading – 0.85 lagging <br />Peak efficiency %97.7 <br />CEC weighted efficiency %97 <br />Night-time power consumption mW 60 <br />MECHANICAL DATA <br />Ambient temperature range -40°C to +60°C (-40°F to +140°F) <br />Relative humidity range 4% to 100% (condensing) <br />DC Connector type MC4 <br />Dimensions (H x W x D) 212 mm (8.3”) x 175 mm (6.9”) x 30.2 mm (1.2”) <br />Weight 1.08 kg (2.38 lbs) <br />Cooling Natural convection – no fans <br />Approved for wet locations Yes <br />Pollution degree PD3 <br />Enclosure Class II double-insulated, corrosion resistant polymeric enclosure <br />Environ. category / UV exposure rating NEMA Type 6 / outdoor <br />COMPLIANCE <br />Certifications <br />CA 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. 107.1-01 <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 C22.1-2018 <br />Rule 64-218 Rapid Shutdown of PV Systems, for AC and DC conductors, when installed according to manufacturer’s instructions. <br />IQ8SP-12A-DS-0067-03-EN-US-2022-12-27 <br />2352 N Riverside <br />Dr1/23/2025
