Are you trying to say there was never a problem? Both Signature Solar and Growatt agree that there is an issue here. The PV input voltage range is 30 volts to 115 volts. The incoming voltage from the array was between 36 volts to 49 volts. The voltage from the array was within the specification of the Growatt SPF 3000. Both signature solar and Growatt agree that the 3P configuration should have worked without issue. They believe it may be a bug in the firmware and are investigating it further. For now as long as you a series configuration for Series/parallel configuration to get the voltage up then it will work.The GW is working just as I described it will under low light or low yield conditions. There won't be a fix, the problem really isn't the GW, the problem is PV.
Flat mounted panels seem more prevalent to this issue, any shading with the flat mount and the PV can not supply the load the SCC puts on PV.
So you say there won't be a fix but Growatt says they are now working on a fix. So.. there is that fact.
