Introducing the Enphase IQ9S-3P Microinverter for 480 V Three-Phase Commercial Systems

Added: 2026-05-30

[00:00:03]Introducing the all new IQ9S 3P 480 volt [music] in-phase commercial microinverter.

[00:00:15]The IQ9S microinverter is powered by cutting-edge [music] GaN technology that is made in America.

[00:00:21]It delivers unmatched efficiency and reliance against grid fluctuations.

[00:00:27]And it sets a new standard for performance and reliability.

[00:00:31]The pre-installed mounting bracket allows the IQ9S 3P to attach to any rail-based system.

[00:00:37]The MC4 connections are integrated directly into the microinverter, allowing for seamless plug-and-play connectivity with the solar module.

[00:00:47]LED indicators for the IQ9S 3P commercial microinverter tells you the operational status for each microinverter.

[00:00:55]Connect the AC output directly into the four-pin phase-balancing in-phase QD cable.

[00:01:04]The American flag symbol indicates that it is made in America.

[00:01:09]This all comes in an enclosure that is class two, double insulated, corrosion-resistant polymer designed for outdoor use in wet locations, meeting NEMA type 6 standards.

[00:01:23]Let's take a closer look at some of the other IQ9S 3P specifications.

[00:01:30]The IQ9S 3P 277 is Fiat compliant, qualifies for 24.8% domestic content, it is made in USA, and comes with a 25-year warranty.

[00:01:45]It has an operating voltage of 277 line to neutral, a maximum output power of 548 volt amps, and is typically paired with modules ranging from 500 to 770 W.

[00:02:00]It has an input DC voltage range from 18 to 65.

[00:02:08]And you can put up to 24 of the IQ9S-3P in a 20 amp branch circuit.

[00:02:17]The IQ9S-3P uses the same phase rotating QD cable, accessories, and software as [music] the IQ8P-3P and the IQ9N-3P commercial microinverters. [music] This means that if you've already installed the IQ8P-3P or IQ9N-3P commercial microinverters, you can easily install the IQ9S-3P.
