<p class=MsoNormal><font size=2 color=navy face=Arial><span style='font-size:
10.0pt;font-family:Arial;color:navy'>I am having a somewhat similar problem
with a recently installed IG5100. I have it installed in conjunction with
an Outback battery based system for AC coupling. We have it set up to
divert its loads to an electric ice melter and then to a large electric heater
as the battery voltages climb. A third relay cuts the array power between
the Fronius and the AC panel if the battery voltage continues to climb to
unsafe levels. <o:p></o:p></span></font></p>
<p class=MsoNormal><font size=2 color=navy face=Arial><span style='font-size:
10.0pt;font-family:Arial;color:navy'>When we have heavy sunshine and low house
loads (second home) and the array output climbs above 3000 or so watts, we
continually get a “State 108” code and shut down cycles each time a
relay trips on a diversion load. I have worked with both Outback and
Fronius (who have been great!) but at this point we are all baffled. I
think my next step, especially after reading the above post is to replace the
Fronius. Then as a last resort swap the IG5100 out to a couple of SMA 3000US’s
(a 6000US does not configure well with the 28 evergreens).<o:p></o:p></span></font></p>

We've installed about 20 IG/LV series inverters. Some failures required
only replacement of GF cards, most required replacement inverters. We've
had several DOA when new, one was replaced by Fronius with a rebuild even when
we warned in writing that we would not accept a rebuild (it had multiple <st1:place
w:st="on">KOs</st1:place> pulled in the chassis -- just not acceptable).
As of right now, we have 7 in non-operational status awaiting
replacement. No kidding.<br>
<br>
There maybe be one or two that have not failed, but this is offset by those
that have failed multiple times. The biggest failure rate is of the 6
LV4550s on an exterior north wall 2 blocks from the beach (<a
href="http://millersolar.com/Portfolio/Commercial/Voler/voler.html"
eudora=autourl>http://millersolar.com/Portfolio/Commercial/Voler/voler.html</a>).
These have been replaced three or four times each and are coming out as soon as
we finalize the paperwork, with 3 10K Plus series inverters going in.
This will require extensive rework, but we are being paid for our time. The
Fronius staff has been very nice, but pretty slow to respond.<br>
<br>
I hate to report bad reviews to this forum, but it is what it is.<br>

100% of what quantity? Are there any special conditions that may have
contributed? Were they minor problems?<br>
