Thanks for your input, Carl. That data looks pretty grim. This is a
serious black eye for our industry.

Ken,
We installed our first Enphase units in Dec 2009, and our *last*
Enphase units in 2011. 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
