[RE-wrenches] update on micro-inverter reliability

[Daniel Young]

Hello Wrenches,

 

I've been looking at the list, and it seems it's been over a year since
there was any detailed discussion on the reliability of Enphase/other
micro-inverters. With the 2014NEC finally rolling out in my state, I wanted
to re-evaluate them as an option. We have several M190 installs that have
bad failure rates (one job is having all the 190's replaced with 215's on
Enphases dime) but we really have too few 215's and 250's out there to be
able to form an opinion.

 

A year ago I kept seeing anecdotal evidence the 215's and 250's are MUCH
more reliable, but I'm looking for REAL data if it's available. Anyone have
access to warranty claims by enphase on a per product basis? Or better yet,
failure rate vs service life of the units, now that the newer generation of
inverters have a decent install base and kind of relevant in service time?

 

With Regards,
