Enphase IQ6 vs IQ6+ Comparison

The Enphase IQ 6+ Microinverter came out not too long ago, built on the sixth-generation platform. We compare the IQ6+ with the Enphase IQ6 Microinverter (no longer produced), and the differences the plus sign makes between the two microinverters.

Here is a comparison between the two Enphase systems, IQ6 vs IQ6+, with the differences between the microinverters highlighted:

Conclusion of IQ6 vs IQ6+:
The Enphase IQ6 and IQ6+ are both compatible with the Enphase IQ System, but if you are looking at 72-cell modules and/or panels with a wattage of over 330W, the IQ6+ will be needed for your project. The IQ6+ is also a more powerful microinverter as well. On the other hand, the Enphase IQ6 is a great option when you don't need the extra power especially since it's cheaper.
