Good discussion,
I have a Growatt SPF 5000 ES running at 040 04 301, 041 04 301 firmware, except for the Shine WIFI communication, It's been running stable since the system was commissioned early last November, the Shine has been inadvertently freezing, which requires cycling the inverter power to re-establish communication.
I believe the issue is within the 5000ES, it seems to be timing out from loss of communication. I tried the Solar Assistant work around, however, the issue still remains, please see attachment. Does anyone know if there are firmware release notes that may describe at what Growatt firmware version I need to be at in order to reliable monitor my system, or what firmware version is working for you? I have made repeated and exhaustive attempt to for guidance from Signature Solar to no avail.
Also, I believe I have the older comm board, since its running siliconlabs driver's which are up to date. The Solar Assistant using Pi seems to run well as far as I can tell. I have also connected using PV Keeper 2.0 software and it seems to be the worse of the three device connections.
Once again, the system is presently running well, I'm hesitant to just randomly upgrade firmware, I believe that at some level they remove the ability to use the auxiliary contacts, which is presently working on my unit. Nonetheless, reliable data acquisition is a high level for me. Gracias.
