IQ Grid Tied Microinverter System

Enphase has improved upon the IQ series, and introduced the improved IQ7/IQ7+ microinverters, and this year will further transition to the latest IQ8/IQ8+ series. IQ7 made improvements to the IQ6, by reducing component count, and allowing the inverter to auto-detectng between US Type 240VAC-60 hz grids and European 230VAC-50 hz grids, thus enabling these microinverters to be installed almost anywhere in the world. IQ8/IQ8+ microinverters will have improved functionality and advanced features. These inverters will be part of an integrated solar, storage, and energy management platform that Enphase calls Ensemble. A new and improved AC Battery with integrated IQ8 microinverters will be introduced towards the middle of next year, and combined with additional switchgear will allow the system to be able to operate without the grid being present, and will be able to provide both load management and backup solutions. With increased efficiency and a 25-year standard warranty, these lightweight microinverters utilize a simple two-wire cable system that lower cost and reduce installation time. Communications to the Enphase IQ Envoy is now over the current conductors, eliminating the need for a neutral wire in the PV system. Enphase IQ microinverters conform to NEC 2014 and NEC 2017 section 690.12 and C22.1-2015 Rule 64-218 Rapid Shutdown of PV Systems, when installed according manufacturer’s instructions, and are compliant to new Rule 21 (UL 1741-SA) requirements. IQ micros have a 97% CEC efficiency rating. The IQ7/IQ8 can be used with 60-cell modules up to 350W while the IQ7+/IQ8+ can work with 60-cell or 72-cell modules up to 440W. Enphase has no enforced DC/ AC ratio. Visit the Enphase compatibility calculator located at for compatible models. Enphase IQ microinverters have an exchangeable cabling system, where you can change the input connectors from MC4 to H4 if needed. AEE Solar will be stocking IQ/IQ+ microinverters with MC4 connector as standard. The IQ Envoy gateway communicates over Powerline with the microinverters, providing module level reporting of PV Production. A new commercial three phase IQ Envoy is available to configure with 3P-208/230/240 utility grids.
