Enphase is looking a little shaky for the application at this
point. Does anyone know of an efficient inverter that would work
out well to AC couple with a pair of Outbacks on an 1800 Watt array. The
90% efficiency range is what I've been seeing. The new high
frequency SMA inverters look good, but last I heard were still tied up at
UL.<br><br>

<dd><font size=2 color="#0000FF">However, I am considering Enphase for a
large res retrofit which will recieve CSI funding. I am obligated to
provide my customer equipment that will be warrantied by the manufacture
for 10 years. I have to have certainty NOW that the warranty will be
honored in the application. I can not base the fulfillment of my
contractual obligations on the passing whim of the support technician of
the day. My project involves placing the Enphase below the ATS on a gen
back up system, an application which Ehphase will not warrant in
writing.<br>

at all? All you folks who are putting Enphase on the load side of
grid-tied, battery based inverters need to ask yourself the same
question. It appears that Nick already has his answer.<br>

<dd> I bet if you don't push the issue, they will cover
the warranty. If the inverter is truly failed, I am sure that
you won't have an issue. But since they are so reliable, that
probably won't happen anyway. However, if you were to install them
in an ''off-grid" application, you can't expect them to guarantee
the performance, which is what a 'written' guarantee implies. I bet
SMA won't provide a written guarantee that they will perform when coupled
to an FX inverter, either.<br>
