Hi,
I have two customers complaining about flickering lights at certain times. I found this rather non-verbose :-) reference "Fronius has a special firmware available, on request, that fixes light flickering issues that occur on certain installations under certain circumstance".
One customer also has a DC coupled SmartSolar charge controller; the other one does not yet have that.
These customers have SMA PV inverters, not Fronius PV inverters. Does anyone know which "certain" installations and "certain" circumstances are referred to here so I can discuss it in sufficient detail with SMA?
