Carl -
We just received an identical response from Enphase on a site that has M210s with SunPower installed towards the end of 2011. They want to monitor and wait. 4 out of 16 of the units have failed so far and we are requesting to replace all of the remaining units to avoid all the multiple trips. We have another site with black ooze coming out of a M190! I have to admit that things aren't looking good with Enphase right now especially since it's only been a couple of years!

The breaking point for me was when the first 215 failed about 6 weeks into production, oozing black slime out of the case. Enphase did two complete system for us last year(one M190 and one D380 site), when they hit failure rates of 23.7% and 25% respectively. It seems the wind has shifted at Enphase lately though. We had another site hit 28.6% failure rate this spring and asked Enphase to upgrade the site to 215s. No dice. Here is the response from Enphase: " As we discussed we would like to start a 90-day monitoring cycle for the XXXXXXX site. During this process a hold on any current replacements and monitor the site to see the site stabilizes. A check will be completed every 30-day to assess the site for any production issues. After the 90-day monitoring period replacement devices will be sent out. The customer will also be reimbursed for any loss of production seen during that time. At the end of the monitoring cycle the site will be assessed if a more aggressive approach is necessary." Needless to say neither the customer or myself were happy with the response. This weekend we had another site hit 19% failure rate ( four failures since the beginning of the year) How long will we be in this mess? Looks like awhile longer. I've attached a little table with failure rates for our Enphase systems. With Regards Carl Adams SunRock Solar
