Enphase Energy's IQ8 series micro inverters are the first grid-forming micro inverters with split-phase power conversion capability - complying with the latest in advanced grid support (including CA Rule 21 for UL 1741-SA) and capable of remote automatic updates for changing grid requirements.
The IQ8 series' brain is an application-specific integrated circuit (ASIC) with a chip built with advanced 55nm technology for high-speed digital logic and extremely fast response times for reacting to changing load demands and grid events, alleviating constraints on battery sizing for energy storage systems.
The IQ8A Micro Inverter is compatible with today's highest power solar panels up to 500 Watts and operates at an incredible 97.5% CEC efficiency. The IQ8A makes installation easy with simple two-cable wiring, and ensures you get the most out of each and every solar panel in your system - regardless of shading or other issues with any of the other panels.
In addition to maximizing PV production, IQ8As also provide module-level monitoring - greatly simplifying system troubleshooting - and fulfill NEC Rapid Shutdown requirements. When the grid goes down, they automatically shut off. They're also a great choice when expanding the system in the future is a possibility - simply add more solar panels and IQ8s as needed without having to worry about overloading a string inverter.
*Notes about system grounding: Electrical code requires both the Grounding Electrode Conductors (GEC, used between the grounding electrode and the point where a normally current carrying conductor is intentionally bonded to the ground) and Equipment Grounding Conductors (EGC, which grounds non-current-carrying metal parts of the system - i.e. racking and solar panel frames). Because Enphase IQ8A Micro Inverters have DC integrated ground (the DC circuit is isolated and insulated from the ground), they do not require a GEC. Additionally, the Equipment Ground requirement is met for the microinverter because the ground conductor (the green wire internal to the Engage Cable) acts as the EGC.
