[RE-wrenches] Enphase failures

[Carl Adams]

Marco,

Here is a summary of our experience with Enphase to date
  13.1%  overall failure rate  25.6%  M190 failure rate  25.0%  D380
failure rate  2.1%  M210 failure rate  5.6%  M215 failure rate

We have had two full site upgrades last year.  One from M190s - 215s, the
other from D380s to M215s.  No problems at those sites since the swap out.
We have two other M190 sites in line to be swapped for 215s once the 90 day
monitoring period is up.

Just swapped 3 of 15 inverters on a site last week.  When I showed up with
the 3 new inverters two more had died, they are now enroute from Enphase.
Those failures are reflected in the above statistics.

With Regards
Carl Adams
