[RE-wrenches] under performing Enphase inverters

[SOLARPRO at aol.com]

We have had two 210's go dark.
With SunPower 225.
We keep one spare 210 in stock (have not had any 190's go yet).

For the first time, several weeks ago, after 40-50 Enphase  installs, we’ve 
come across at least two M210s that we putting out  consistently lower 
outputs than their immediate neighbors. 
We replaced the two mods first, which made no  difference.  Then, in 
consultation with Enphase, replaced the  M210s.  After replacing them, the power 
output was as it should  be. 
Now I’ve got another suspect system with several  underperforming mods out 
of (36). 
Has anyone else had this experience? 
Thanks, 
marco
