As a quick clarification- SolarEdge requires PV WIRE per 690.35.
Regular USE-2 doesn't work for these systems.<br>

<div>Marco,</div>
<div>We installed our first Enphase system in December 2009, and
our last in December 2011, when their high failure rate became a
problem. (Currently 10%+ for us). We were only installing the
Enphase units on sites with shading issues, as a means to
mitigate conditions. </div>
<div> After moving away from Enphase, we selected SolarEdge as
the solution of choice for those sites. The installation labor
is comparable to the Enphase solution, separate device under
each module. One clear advantage is that there are no custom
trunk cables required, just the standard USE-2 cable and
connectors. </div>
<div> Our field experience has been better than expected
production, and 1.4% failure rate. In December we installed a
SolarEdge system just down the street from a site where we had
previously installed an SMA string inverter on an unshaded site.
The SolarEdge system has some shading. Both arrays have roughly
the same orientation and pitch. To date the SolarEdge system
with shading continues to out produce the unshaded SMA system by
5-8% kWh/kWp. </div>
<div><br>
</div>
<div>I agree with your intuition on fewer components making a
better solution and "IF" there is a reliable solution that
accomplishes this that would be preferred. </div>
<div> I just priced out the Mage AC module (SolarBridge
technology) side by side with the Mage - SolarEdge combination
and the later is less expensive equipment wise but I think that
advantage would be erased by labor savings on the install. </div>
<div> All that said I'm still a fan of the old fashioned string
inverter solution unless the site shading conditions and or
array geometry require an alternate solution. </div>

<p class="MsoNormal"><span style="color:#1F497D">I’ve been
educating myself
on the Solar Edge product v. using micro inverters. If
you click on the

using their product over
micros. <o:p></o:p></span></p>

<p class="MsoNormal"><span style="color:#1F497D">Intuitively,
it seems to me that
if you can accomplish what you need to accomplish (DC
power from the PV mod to
usable AC power) with fewer parts (as in a micro inverter
instead of a DC-DC
converter and a separate inverter), then that approach
makes more sense.<o:p></o:p></span></p>
