JK BMS: does this not speak any protocol that the 18KV will take?

[ikidd]

I'm trying to get my Luxpower to speak to the battery pack, because if it doesn't have comms, it won't run the inverter. Currently I'm setting it to LA to get it to work because I can't seem to get the thing to talk to the B2A24S115P using any of the protocols it maps to in the manual. I would have thought Pylon would be common to any BMS and inverter combo, but I'm seeing indications that the JKBMS doesn't talk Pylontech? I am using RS485 but I've tried CAN as well just in case. I don't know if the wiring for CAN is the same as 485 or if the dongle I got for the JK needs to be rewired for CAN.

Any pointers? Given the popularity of the JKBMS, I would think this isn't the first time this question was asked but I can't find any posts relating.

Indeed it does not talk directly.

But if you are savvy with tech you can try this to get it to work:

CAN and RS485 BMS Interface with multiple emulated Inverter protocols for JkBms Jbd BMS Daly 123Smart

Hello! Can the RS485 signal be sent to for example Solar Assistant as well or is just only for comms between BMS-s? If yes, would the wiring be the same as on the first page and on the Google Drive pictures? the connection between jkbms and interface is uart u dont need to use rs485 port. if...
