First you can look at the serial output of the program and press the button, which enables CAN debug output. |

Hey Arminjo,
I've loaded a Nano with your code and connected between a JK BD4A17S4P and a Goodwe GW5000-ES-20 inverter, however the inverter always has the battery staying in Standby (or Spare) mode with no charge or discharge.
There are several packs with BD4A17S4P's paralleled, but just trying to get 1 BMS working first.
Attached is a dump of how the inverter sees the battery using inverter_check.py from https://github.com/marcelblijleven/goodwe
inverter_check.txt
The inverter is currently configured to be using a Pylon US3000 (x1) battery, though get similar results with any Pylon profile on this inverter.
The battery status doesn't change even when using 'self-use', 'general' or 'off-grid' modes on the inverter.
Is there a potential (or known) problem using your code with newer generations of Goodwe inverters like ES Gen2 and ET series...or that type of JK BMS?
