CAN and RS485

[Taher Sylla]

I have Growatt SPF 5000 ES inverters, I connect them always with LFP batteries with BMS communication, also via RS485 only, I would like to know, some of the batteries I install have RS485 and CAN communication, which one is better ? And why ? The distance between the battery and inverter doesn't exceed 2m

CAN is faster but it may not make much difference in this application.
