William,
Just the opposite situation here. We've been using Fronius almost
exclusively for the past four years with very few issues at all. The
few we have had Fronius tech support was all over it PDQ.
Go figure.

We have had an almost 100% failure rate for Fronius inverters. This
is including replacing many of them multiple times. We are about
ready to replace 6 LV4550s with 3 Plus 10,000s. I will let you know
how it works out, but we are very underwhelmed.

Wrenches,
A Fronius IG 4000 is doing some weird cycling. Every 45 seconds the
voltage pops up to Voc and drops back to Vmp immediately followed by
a downward ramp of voltage and corresponding rise in current. This
repeats continuously. PV array Vsc is constant and all strings are
+/- 1 volt DC. I spoke with Dan at Fronius and they are working on
it. BTW, very helpful and immediate response from Fronius.
Has anyone else seen this occur? This is the second problem with
this inverter so I am wondering how Fronius is holding up for others.
Kindest Regards,
