Apologies and good point It’s the Growatt SPF5000ES and Pylontech US3000C

hi guys what worked for me in the end (and after getting guidance from a Bundu Power tech was the following) Using a straight through cable (Pin1 to Pin1 etc) ; Run it CAN port to CAN port and change setting 5 to LI, Program 52 That was all I needed.

Thanks. I will get a cable made up today and give it a try. Appreciate the help

Thanks Iss The attachment is unavailable. With regard your other post on this topic, I read it thanks, and have a question. You mentioned the following. “cross-over cable 1&2 to 7&8 as below. 6 other cables are straight through. Meaning from above img. Orange to brown remains in that order” So pin 1 goes to pin 7 and 2 goes to 8? The diagram on your post seems to show 1 to 8 and 2 to 7 (unless I’m reading it wrong 😃) Thanks

Thanks This didn’t work for me assuming it’s a straight cable that you used.

Hi, I have a Growatt SPF5000ES and Pylon US3000C battery. No solar , so being powered from the grip. I am struggling to get the BMS comms working. When going into Prog 5 , LI, then either choosing Prog L02, 036 or L52, 036 by battery stops charging. Only when I am in USE mode does it charge. Perhaps my cable is not working ; straight through UTP cable like it came with. I've tried from the CAN port on inverter as well as RS485 port to both the CAN and 485 ports on the battery but still no success. Any suggestions please? Thanks
