<DIV><FONT face=Tahoma><SPAN class=904051102-24102011>I was just about to
order a pallet of Yingli 255 modules and noticed the spec sheet calls out
Amphenol H3 connectors. I looked at the spare 230W module in the shop from a
July install and, just as I remembered, it had MC connectors. So I
looked at the latest 230W module spec sheet and it too had been changed to
Amphenol. </SPAN></FONT><FONT face=Tahoma><SPAN
class=904051102-24102011>All Yingly mods apparently now come
only with PV wire & Amphenolconnectors. </SPAN></FONT></DIV>
<DIV><FONT face=Tahoma><SPAN class=904051102-24102011>I know the article
in the recent Photon comparison of connectors pointed out that
though many different brands would interchange, snap together and hold
fast, that they should not be trusted to create a low impedance
connection nor be watertight just because they fit. The article went on
to say that connector mfgrs have resisted creating a standard for their
industry. I can't say that I blame them but it sure gives us another potential
glitch to avoid.</SPAN></FONT></DIV>
<DIV><FONT face=Tahoma><SPAN class=904051102-24102011>Just a note, at SPI I
came across a display of crimpers for different brands of PV lead connectors.
There were well over a dozen different varieties of expensive
looking hand tools on display. While I didn't look closely at them all
I could easily see that Tyco & MC were clearly different and
probably not interchangable. Others looked similar but a difference of only a
few thousandths of an inch can spoil your day when discovering that A doesn't
fit into B like it should. </SPAN></FONT></DIV>

pissed at the PV industry about. </SPAN></FONT></DIV>
