[RE-wrenches] Enphase failures

[William Dorsett]

These are the statistics on what total numbers? This is the great value of
this forum. Government sources with independent testing refuse to endorse
any specific brands and the rest is left to whichever manufacturer of
whatever integrity, has the loudest bugle. Thanks Carl.

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

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 support from our Enphase
friends, he has gone back to the site many times and is wondering at what
point Enphase would authorize replacing the whole kit and caboodle of all
them thar micros.

 

Anyone have anything similar happen?

 

Finally, are you seeing access yet to the new M250?

 

Thanks,

marco
