One weakness did present itself to me during my installation

A while back there was a discussion about the reliability of Enphase
inverters. As I understand, they have been selling like hot cakes,
so a lot must be installed. Some sort of track record must be emerging.
Has the promised reliability of these inverters been met? Can they
be connected to
Can anyone think of a more brutal environment for a piece of electronic
equipment than under a solar module which day in and day out experiences the
elements and temperatures of 130+ plus F?
Despite any so-called accelerated life-cycle testing and estimated mean time

I'm with you. Regardless of how well the company stands behind their
product, a failure of any kind reflects back on the system integrator/
installer. That would be us, ladies and gents...
I've been down this road before with PV Powered in the early days with
inverters which they now
I put a temperature probe under the modules almost every job, and it is always
drastically lower than the module itself. A frying module at 130 might have an
ambient temperature underneath in its shade of 89 degrees. the specifics are
always surprisingly low relative to touching the panel and
I'm also concerned about the issues brought up here. I have two
possible projects that would benefit from Enphase due to the fact
that the modules will go on more than one roof, with significantly
different orientations. In one case, there are shading issues as well.

It sounds like you could run your dc wires up the rows and have
all your inverters grouped on the top rail. That a one man call to
trouble shoot a system which has been a big
We've got a couple of installs that have been in for just under a year, and
completing a third. We would have done more if the inverters had been more
easily available.
Our first install we noticed something that wouldn't have been apparent on
string inverters, and the process we went through
