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
Friends:
We need stats on the alternative equipment.

PS: My failure rates on a very limited number of inverters is very reasonable
(never needed to tabulate this data).

We have had two full site upgrades last year. One from M190s - 215s, the
other from D380s to M215s.
Marco ,
Haven't seen any M-215 failures (yet) but have had many, many M-190 and M-210
failures. Haven't seen a 250 yet.

What are you all seeing as far as failure rates for the Enphase M215s?
I've got a contractor friend on O'ahu who installed a 60-mod system (using
the M215s) and has had failures with nine of the buggers, leading to a
rather unhappy homeowner.
While my contractor friend has had some level of
accessibility built in to design is also a plus - not always possible,

The M190 had a first year failure rate far higher than the M215, of which
we have only swapped a couple. I can echo your frustration with the M190,
especially the 208V model. Based on the M215 performance so far, we are
happy to continue selling Enphase.

I'm wondering how many of you have had Enphase failures in the field. Basically
every one of our sites with M175 or M190 has seen failures. Most of those are
one their second wave of replacements. It appears these have a linear failure
