They are actively producing the AC panels in their NeON 2 line, which is the 380w ones from your first link. My supplier should be getting the 380's by around the new year, as they just switched over from the 375's. Then there are also 370w ones with the black backsheet.

<p>That's a pretty hefty reimbursement for replacing a failed unit,
they must of actually been thinking about the installer. I also
like the high efficiency PV they paired it with, 395 watts and its
still 60 cell, inverter 97% CEC . <br>
</p>
<p> Sorry about the wrong link, here's the correct one:</p>

<p> Should I assume that if the fire department pulls the
meter at a house fire, that qualifies as rapid shutdown?</p>

<div dir="ltr">Hi Bill,
<div>I started installing the LG AC modules this year. So far
they seem like a great product. I have about 120 of them in
the field so far, but I have had 0 issues. I used to install
the Sunpower AC modules, but I like these more. There are no
DC leads at all. There are just AC cables coming out of the
microinverter on the back that connect to the next panel, so
there is no AC drop cable. It takes a little getting used to
the best ways to wire manage, but I've been finding it pretty
straightforward. The commissioning process goes much more
smoothly than it ever did with Sunpower. Two minor drawbacks -
One is that with the commissioning, the customer needs to log
in and approve the system before the monitoring will work.
Two, is that the panel and microinverter are entirely one
piece, so that if a microinverter were to fail the entire unit
needs to get replaced. LG does offer a $450 labor
reimbursement, and I have not had any issues yet, but that
will be a more involved service than a simple microinverter
replacement. Overall, these sell at a good price point and
make for a simple installation. I wish that they would still
offer AC panels in their NeON R line as well, but supposedly
they were not selling very many of those.</div>

Not sure if AC panels are being installed yet, am
