IQ8 Microinverters, our latest product family, are inherently bi-directional and Enphase’s AC coupled distributed architecture is benecial for small grid-forming, power-conversion devices. IQ8 Microinverters are completely photovolataic (PV) systems, such as those in social housing and plug-in software-dened, using a new ASIC that is approximately 1,000x faster than balcony solar. There are approximately 2.4 million homes in the social housing the previous ASIC used in IQ7™ Microinverters. This allows them to respond segment in the Netherlands; each home could potentially install a PV system instantly to changing conditions and eliminates all sizing constraints between with six to nine panels. To improve installation cost, we developed a pre- ® batteries and solar inverters. The grid-forming capability of IQ8 also enables wired solution for social housing which integrates the IQ Gateway, IQ Relay, Sunlight Jumpstart and Sunlight Backup, allowing solar systems to function and cellular modem. We are also working on balcony solar solutions, where when the utility grid has an outage, even when no batteries or EVs are present homeowners install one to two panels on their balconies, patios or gardens or have depleted batteries. and connect the output, currently limited by regulation to 800 W, to a regular home AC socket. Our solution will also enable PV panel output, even when the “IQ8 Microinverters pair seamlessly The IQ8 product family includes microinverters with peak output AC power grid is down, to support small loads during the day. We expect to introduce with solar panels up to 650 W of ranging from 245 W to 480 W. IQ8 Microinverters pair seamlessly with solar variants of this product for dierent geographic regions in 2025. DC power and up to 14 amperes of panels up to 650 W of DC power and up to 14 amperes of DC current. The DC current.” IQ8P Microinverter supports up to 480 W AC output power and solar panels rated up to 650 W DC, allowing us to address markets where larger format panels are popular, e.g. in Latin America and other emerging markets such as India. The IQ8P Microinverter, along with a new 3-phase cabling system ® Gateway, is also available for U.S. small commercial solar installations and IQ ranging from 20 to 200 kW, which is ideal for gas stations, schools, hospitals, churches, small businesses, and other similar facilities.
