Enphase Energy Micro Inverter With Integrated Ground

PART # IQ8A-72-2-US

What is so great about Micro Inverters? Enphase Energy micro inverters do all of the inverting of power at the solar panel level - DC power going in and AC power coming out. Another big benefit is panel-level monitoring. You'll be able to remotely see which panel is not producing and trouble-shoot your system much easier. In addition, if one panel is having production issues, it will not affect the rest of the panels in your system, like a string inverter system would. In other words, if one panel is shaded, it won't negatively impact the output of the other panels. And micro inverters - because of the way they are designed - automatically fulfill 2014 and 2017 NEC Rapid Shutdown requirements, as when the grid goes down, the micro inverter automatically shuts off. Ease of installation with a micro inverter translates into labor savings on the job. They simply are attached to the racking right behind each solar panel, and connected together via Enphase cables. You have the option of choosing landscape or portrait orientation. Lastly, in terms of expandability, micro inverters give you the greatest flexibility, if you find you need to add more power to your solar power system down the road. You simply add another panel/micro to the system - voila!


  • Integrated Ground* - Eliminates the need for a copper grounding wire or WEEB

  • High Performance - Significant energy harvest gains and higher system availability with no single point of failure. Best-in-class 96.5% CEC efficiency

  • Reliable - Industry-leading manufacturing and quality standards create a ruggedized product for all environments

  • Safe - No high-voltage DC in the system means peace of mind and cost reductions

  • Built-in rapid shutdown compliant (NEC 2014 & 2017)

  • Simple - Reduced DC design and install costs with superior flexibility for all projects

  • Intelligent - Precision insights enable faster, easier system and fleet management

  • UL Certified - Meets CA Rule 21 (UL 1741-SA)

Benefits of the New IQ Micro Inverters:

  • Faster to install for installers - the lightweight Q cables are plug-and-play
  • More energy production for homeowners with up to 320 watt peak output power
  • Most efficient inverter of the Enphase micro inverter family, at 97%
  • Integrates seamlessly with the new Enphase IQ Battery for energy storage options
  • Smart Grid ready - complies with fixed power factor, voltage and frequency ride-through requirements, and remotely updates to respond to changing grid requirements

*About System Grounding:

Electrical code requires two types of grounding conductors: the Grounding Electrode Conductor (GEC), which is used between the grounding electrode and the point where a normally current carrying conductor is intentionally bonded to ground, and the Equipment Grounding Conductor (EGC), which grounds noncurrent carrying metal parts of the system, such as the racking and module frames. Because Enphase Microinverters with Integrated Ground have DC integrated ground (the DC circuit is isolated and insulated from 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.
