Larry:
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,
Larry Crutcher
