Of about 500 M190's in the field, I have had -16- failures. I never had a DOA, but many of the failures have been a result of moisture (water) inside of their supposed-Nema 6 enclosure. I have about 150 M215's installed with no problems. The M215 case is much better constructed and compared to the pop-riveted, flimsy M190 case it would appear less likely for a seal to become compromised.

We are still seeing M190 failures trickling in. We have roughly an equal number of M190's and M215's in the field, and we just had our first two M215 failures this week. Compare that to the dozens of M190's we have replaced for our customers and those of failed competitors. All signs point to the M215 being far more reliable. We have never had a DOA unit, which we did with the M190's.

Folks, How is the Enphase M215 doing? Is it showing marked improvements in reliability over the previous generation units? Is the cable system going in OK? I've worked with the M190 and M380 but not the M215?
