IQ8 and IQ8+ Microinverters

Our newest IQ8 Microinverters are the industry’s first microgrid-forming, software-defined microinverters with split-phase power conversion capability to convert DC power to AC power efficiently. The brain of the semiconductor-based microinverter is our proprietary application-specific integrated circuit (ASIC), which enables the microinverter to operate in grid-tied or off-grid modes. This chip is built using advanced 55-nm 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-and-play connectors
  • Power line communication (PLC) between components
  • Faster installation with simple two-wire cabling
High 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 modules
Microgrid-forming
  • Compliant with the latest advanced grid support**
  • Remote automatic updates for the latest grid requirements
  • Configurable to support a wide range of grid profiles
  • Meet CA Rule 21 (UL 1741-SA) and IEEE® 1547:2018 (UL 1741-SB 3rd Ed.)
NOTE:
  • IQ8 Microinverters cannot be mixed with previous generations of Enphase microinverters
  • (IQ7 Series, IQ6 Series, and so on) in the same system.
  • IQ Gateway is required to change the default grid profile at the time of installation to meet local Authority Having Jurisdiction (AHJ) requirements.

(1) No enforced DC/AC ratio.
(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 branch in your area.
