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.<br><br>

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. <br><br>
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.<br><br>
