After a pilot test run earlier this year, Enphase is now shipping their IQ8 microinverters in North America. The Enphase Energy System with IQ8 comes in four configurations: Solar Only; Sunlight Backup with no battery and the addition of IQ Load Controller to only support essential loads during an outage; Home Essentials Backup with a small battery; and Full Energy Independence with a large battery. Solar Only is a standard grid-tied system while the other three are grid-agnostic and need the Enphase IQ System Controller 2 to island a home during an outage.
