Will system owners use the same Enphase App to monitor their Commercial Enphase Energy System as their home energy system?
  • Yes, all system owners will utilize the same app, irrespective of system type. Owners with multiple systems can access all their Enphase systems from a single login to the Enphase App.

What are the power output levels of IQ8P-3P and IQ8H-3P?
  • IQ8 Commercial PV microinverters will be available in two variants. IQ8P-3P with 470W maximum continuous power (480W, peak power); and IQ8HC-3P with 380W maximum continuous power (384W, peak power).

What modules will be compatible with the Commercial Enphase Energy System?
  • IQ8 Commercial microinverters are compatible with high-power modules from 54-cell up to 72-cell with full or cut-cell configuration. 

Does Enphase offer, or plan to offer, any design-related services to Commercial Enphase Energy Systems installers?
  • Enphase is currently offering, for a limited time, design reviews at no charge for commercial systems. Separately, Enphase is currently offering comprehensive design services for purchase to a select group of EIN installers. If you are interested in procuring design services from Enphase for your prospective IQ7+ or IQ8 Commercial projects, please reach out to your RSM.

Are IQ8P-3P and IQ8H-3P high-powered, three-phase versions of residential IQ8 Series Microinverters?
  • No, the IQ8P-3P and IQ8H-3P constitute a separate IQ8 Commercial PV product line designed specifically for three-phase installations only. The IQ8 Commercial Microinverters feature an entirely different form factor and mounting bracket, and are only compatible with the three-phase QD Cable and IQ Commercial Gateway 2. IQ8PV microinverters are only compatible with single/split-phase systems utilizing Enphase Q Cable and IQ Gateway.

What are the features of a Commercial Enphase Energy System?
  • The Enphase IQ8 Commercial PV System is a grid-tied, three-phase, 208V PV solution that will be fully compliant with IEEE1547:2018 standards upon release. Each IQ8 Commercial microinverter, either the IQ8P-3P or IQ8HC-3P, connects to a single PV module and integrates with the Enphase IQ Commercial Gateway 2 and Enphase monitoring and analysis software. The IQ8 Commercial PV System will offer system-level rapid shutdown compliance with UL-listed PV modules; offers advanced grid functionalities, voltage and frequency ride through, and neutral sense capabilities.

Will installers use the same commissioning and monitoring software for Commercial Enphase Energy Systems as I do for other Enphase installations?
  • Yes, you will use the same commissioning application for IQ8 Commercial PV Systems and you will be able to monitor your entire fleet of installed systems, irrespective of individual site type or microinverter. In anticipation of IQ8 Commercial, Enphase plans to rollout advanced fleet management and kiosk features to our existing software application in 2022. These new features will be accessed through your existing dashboard and login credentials.

What three-phase commercial solutions does Enphase offer to installers?
  • Installers can currently deploy Enphase solutions for three-phase electrical service customers utilizing the Enphase IQ7+, Q Cable and IQ Commercial Gateway. This provides a 208V three-phase solar PV solution compatible with 208V three-phase electrical main service panels and 480V electrical main service panels when the PV is connected to the low side of a 480-208 transformer. For locations requiring loss of phase detection the Enphase Three Phase Network Protection Relay, which includes the IQ Commercial Gateway, provides loss of phase detection.

Can I use IQ8, IQ8A, IQ8M, IQ8H, or IQ8+ Microinverter with three-phase commercial systems?
  • No, the IQ8/A/M/H/+ is not UL listed nor tested for three-phase applications.

Is the Commercial Enphase Energy System grid-forming capable?
  • No, IQ8 Commercial PV systems will be grid-tied only upon release Spring 2023.

Where can I find more information on the IQ8P-3P and IQ8H-3P from Commercial Enphase Energy Systems?
  • Please visit our IQ8 Commercial page here:


Will the Commercial Enphase Energy System be compatible with battery storage?
  • Enphase has not evaluated nor tested the integration of the IQ8 Commercial PV System with any 3rd-party single-phase or three-phase battery solution and cannot support installations where three-phase solar PV and 3rd-party storage integration are required.

How will a three-phase Commercial Enphase Energy System design differ from a three-phase IQ7+ Microinverter system design?
  • A three-phase IQ7+ system utilizes the IQ7+ Microinverter, Enphase Q Cable (2-wired cable) and the Enphase IQ Commercial Gateway – either standalone or as part of the Enphase Three Phase Network Protection Relay (TPNPR) to provide loss of phase detection. Phase balancing in a three-phase IQ7+ system requires allocating the branch circuits equally across the three phases in the PV aggregation panel.

  • A three-phase IQ8 Commercial microinverter system utilizes the IQ8P-3P or IQ8HC-3P microinverter, the Enphase QD Cable (4-wired cable) and the Enphase IQ Commercial Gateway 2. In no circumstance is the Enphase TPNPR required on an IQ8 Commercial PV system. The QD Cable provides Auto Phase Rotation and Neutral Sense Capabilities. Please visit the IQ8 Commercial information page for configuration diagrams.

When will the Commercial Enphase Energy System components be available to purchase and receive from my distributor?
  • Enphase is targeting availability in Spring 2023.

Will Enphase also launch a three-phase commercial battery solution?
  • Enphase is evaluating storage solutions for three-phase applications. We look forward to providing an update in the future.
