High-powered and Smart Grid-ready, Enphase IQ 7+ Micro Inverters provide the module-level DC-to-AC power conversion portion of an Enphase IQ system. Intelligent plug-and-play design dramatically simplifies installation, and best-in-class 97% CEC weighted efficiency 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, these micro inverters also provide module-level monitoring - greatly simplifying system troubleshooting - and fulfill 2014 and 2017 NEC Rapid Shutdown requirements. When the grid goes down, the IQ 7+ Micro Inverters 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 IQ 7+ Micro Inverters 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 IQ 7+ 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.
