M190 inverters clipping at 140 W
I had 18 panels with the M190 microinverters installed in January 2010 in our vacation home in Berkeley Springs, West Virginia. Beginning in October 2014 one of the inverters began clipping at 140W instead of the nominal 190 W. The second had the same problem beginning in April 2015. In September 2015, the third one failed in the same way and in October 2015 the fourth one started clipping at 140W. With this failure rate, I am surprised that there have not been more reports of the problem. To date I have not had any response from Enphase.
