[RE-wrenches] Fronius IG4000 problem

[William Miller]

Larry:

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 KOs pulled in the chassis -- just not acceptable).  As of right 
now, we have 7 in non-operational status awaiting replacement.  No kidding.

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 
(http://millersolar.com/Portfolio/Commercial/Voler/voler.html).  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.

I hate to report bad reviews to this forum, but it is what it is.
