Product Overview

The Enphase IQ8P Microinverter IQ8P-3P-72-E-DOM-US-2545 is a high-powered, smart grid-ready microinverter designed for 208Y Vac three-phase commercial solar installations. Built for 72-cell and 144 half-cell modules, it delivers 480 VA peak output power and 475 VA continuous output while providing module-level conversion and monitoring through the Enphase ecosystem. Its domestic-content designation makes it a strong fit for projects that require U.S.-made hardware for procurement or incentive purposes.

As part of the IQ Series, this microinverter is engineered for long-term reliability, advanced grid support, and simplified installation. It integrates with the IQ Gateway Commercial 2 and the Enphase App for monitoring, diagnostics, and fleet management, helping installers and system owners maintain clear visibility into performance and uptime.

Key Benefits

High-Power Module-Level Conversion: The IQ8P delivers 480 VA peak output and 475 VA continuous output at the module level, helping maximize energy harvest on commercial and larger distributed solar projects.

Three-Phase Commercial Support: Designed for 208Y Vac three-phase systems, it fits small commercial applications where balanced three-phase interconnection is required.

Domestic Content Version: The DOM-US designation supports projects that need U.S.-manufactured equipment for compliance, procurement, or incentive goals.

Smart Grid Ready: Advanced grid support features and remote automatic updates help the inverter stay aligned with evolving utility requirements over time.

Enphase Monitoring Ecosystem: Integration with the IQ Gateway Commercial 2 and Enphase App simplifies commissioning, monitoring, and maintenance across the site.

How It Works

The IQ8P microinverter mounts beneath a single PV module and converts the panel's DC output into grid-synchronized AC power at the module level. In a three-phase installation, the microinverters are distributed across the array to support 208Y Vac interconnection, while power line communication and the IQ Gateway Commercial 2 collect performance data for monitoring and control. This architecture helps improve system design flexibility, module-level visibility, and operational reliability.

Module-Level MPPT: Each microinverter independently tracks its attached module to optimize output under changing irradiance and temperature.

Grid Integration: The system supports advanced grid requirements and communicates with the Enphase ecosystem for fleet-wide management.

Monitoring and Updates: Installers and owners can monitor production and receive updates through the Enphase App and compatible gateway hardware.

Customer Success Stories

Troy P

EG4 off-grid base kit, Happy with my purchase.

This is the first stage of my three planned purches. I got the eg4 inverter 6000 XP base kit with six 400 watt panels and the two server rack batteries. Did a little online research and followed the instructions and it got set up without any issues. Right now I'm just running it in my garage on a single outlet and have been running dual 750 watt water distillers with it. Once I get the second inverter and a bunch more panels and batteries, I plan on attaching it to my subpanel in my house that has my lights and outlets and appliances on it. Then I'll get a soft start for my AC and blower and run it on my main panel.

Jacob B

Easy Process, Genuine Support

Trying to pick the correct solar system for your needs can be very technical and frustrating. I wanted to thank Yvhan and the Portlandia Electric supply team for their patience and helpful attitudes through multiple calls. I feel like we were able to narrow it down to what worked for me and my family. My system works great and I couldn't be happier to have picked Portlandia Electric Supply.

Patrick B

Off Grid Solar Purchase

I wanted to get an offgrid solar system for years but didn’t know where to start. I found Portlandia Electric Supply on Facebook and decided to submit a quote. Within 24 hours I had a custom proposal that was almost half the price of the companies I had previously got quotes from. My wife and I decided to order online and the kit came in a timely manner and it was an easy install. Great company to work with!

James Martin

Highly Recommend

I would like to take the time to express the outstanding service that I was provided with by Portlandia Electric Supply. They provided me with all the answers to my questions, and after reviewing our quote over the phone I felt comfortable proceeding to order my kit. It’s exactly what I needed and they were there to help us over the phone when we had questions installing it. I highly recommend others in need to choose Portlandia Electric Supply.

Solar Kit for Mobile Work Van

As a professional videographer, I needed reliable power on the go.Portlandia Electric Supply Delta Pro and roof-mounted panels were the perfect solution. Setup was easy, and the kit included everything needed. The Delta Pro powers my cameras, lights, laptop, and a small fridge with impressive battery capacity.

Keith S

Best Tech Support

You folks have been wonderful guiding me through the ins and outs of going solar. Plus your tech guys Rod and Nelson are the absolute best. They explained all the different aspects of inverters, batteries and how to keep them in top condition. Too much more to put here… but no other company has the 100% tech support you provide for your customers!

Coll A

Great Experience

My experience with Portlandia Electric Supply has been excellent. Before the sales, they answered all my questions to assure that I got what I needed. After the sales they continued to support me with answers and help. I had a warranty issue with a unit, and it was handled as well as possible. I would recommend them to anyone looking to go solar.
