The questions were:
Is the battery BMS supplying this data about min/max cell voltages?
What about min/max cell temperatures?
Because if the BMS is not supplying this data, neither the Cerbo and later the inverter will receive it.
This data is broadcasted by the battery on CAN ID 0x373.
It’s not on the basic Pylontech protocol, but all recent firmwares from the Pylontech are broadcasting this information on 0x373.
Also, the cell ids for min/max voltages and temperatures are broadcasted on 0x374, 0x375, 0x376 and 0x377.
It will be a very nice thing for your engineers to implement it and keep up with the actual trend… Just a suggestion…
