Enphase IQ7 and IQ7+ Microinverters

Enphase IQ7 Series Microinverter

Enphase IQ7 and IQ7+ Microinverters

Enphase IQ7 Micro™ and Enphase IQ7+ Micro™ are high-powered smart grid-ready microinverters. They achieve the highest efficiency for your system.  seamlessly integrate with the Enphase Enlighten™, and the Enphase Envoy-S™ analysis and monitoring software. The IQ 7 and IQ 7+ Micro have extended the standards in reliability set forth in their earlier generations of products and go through a million hours plus of power testing, allowing Enphase to provide their industry-best warranty.


When California Rule 21 was put into place, Enphase had to move quickly to comply.  They had run the M-Series, from the M215 to the M250, along with the S280 for quite a few years running.  However, with the new requirement, they rolled out their new IQ Series.  The early reviews were mixed.

On the pro side, installers were quick to comment that the new IQ’s were much quicker to install.  The simplified cabling and raw cable accessories sped up the hook up time on the roof, and the Envoy AC Combiner eased the install away from the panels.  Along with the quicker installation, the new inverters are able to pair with larger modules, maximizing production and keeping with the trend of higher wattage modules.  Finally, somehow with all these positives, the cost of an IQ system was actually less than its predecessor.  So, better product, faster installation, and cheaper price.  Downside?

The main downside is the compatibility.  One of the major perks with micro inverters is the ability to add-on to a current system.  Many of our customers buy a system to get solar rolling on their home, and then add on when the time is right.  Unfortunately, with the IQ Series, Enphase was unable to make the system compatible with the M or S Series, meaning an add-on would act almost like a second system, with a separate Envoy to track the performance of each system.  This left many add-on customers scrambling for M Series inverters that Enphase was no longer manufacturing.

Enter the IQ 7 and IQ 7+.  While the trunk cable remains different between the IQ 7’s and the M Series micro inverters, the Envoy can now track the performance of both systems.  This is a major plus, and will ease the pain of many installers and homeowners alike.

Also, the other major problem with Enphase Micro Inverters, including the 7 and 7+, is that they will not work with 96 cell modules (Panasonic).  This means that one of the top selling modules in the US cannot be used with Micro Inverters, and instead has to be paired with SolarEdge/ Optimizers.  However, good news is on the way… the Enphase IQ 7X.  While this has yet to be released, we will finally have a micro inverter that works with the Panasonic panels!!

Right now, the price of the Enphase IQ7 Series is a tad higher than the Enphase IQ6 Series, but that will likely change in a few months.  To ease the comparison between the different Enphase micros, we have created the table below:


Finally, while most of the wholesalers in the solar market will be getting the IQ 7 and IQ 7+ series in stock in May or June, Tandem Solar is excited to announce that we have them in stock immediately.  Please follow the link below to learn more about the new Enphase products and pricing.
