Hi,
I have an issue with my AC500+2xB300S setup, it started giving error 103 (BMS cable). I’ve tried swapping cables around to no avail, so I would like to request that firmware update is pushed to my system to see if that helps.
Current BMS firmware on my system is 1022.09 and I can see an announcement that there are newer versions.
S/N is AC5002232000277763
