enphase M215 unreliable

I have a 9KV 36 panel ground array system using PH 255 Conergy panels and M215 microinverters installed December 2013. I have had 10 of the 36 inverters fail so far (2nd year). Being able to monitor production of each individual panel is great with the Envoy system. Enphase so far has replaced 7 inverters after several months of waiting (partly due to the installer) and has approved replacement of the other three---still waiting on installer a couple months now. These failures were not picked up on the Enlighten software settings. I picked them up myself since I monitor the system regularly. One was a complete failure. The other 9 were producing at a fraction of the fully functioning inverters, usually in the 50-70% range. I have not been able to get an explanation for such a high failure rate.
