JBD BMS x SRNE HESP Inverter Support

[bmat8]

Hi there,
Looking into this so that SRNE HESP inverter can receive data from my JBD BMS.

And unfortunately I am not well versed in these kinds of things. But where/what would be the output from the rasberrypi (or waveshare?) to the SRNE HESP Inverter?

[ai-republic]

I assume you are connecting 2 JBD BMSes that can communicate via the CAN protocol right?
So normally you can assign an ID to each of your BMSes either via DIP switch or per software.
Then you should assign the first BMS the ID 1 and the second BMS the ID 2 and have them connect to your CAN0 on your PI.
The CAN1 would then go to your inverter.

[bmat8]

Yup eventually 2 JBD BMS but currently have 1. Do you know if I would use the UART or RS485/CAN port from JBD --> Waveshare? Model number is SP24S004

[ai-republic]

As you are using a Waveshare CAN hat you will need to connect to the JBD CAN port.
Do you have the JBD CAN protocol communication specification by any chance?

[bmat8]

Apologies for the late reply. I just got my waveshare today. Unfortunately, unable to find much (if anything) what protocol JBD uses. Their documentation is quite lacking. Currently getting the following error:

2025-10-06 16:24:34.908 | INFO | Thread-3 | toinverter.core.Port:113 | Opening port com0 SUCCESSFUL 2025-10-06 16:24:34.908 | INFO | Thread-3 | toinverter.core.Port:111 | Opening com0 ... 2025-10-06 16:24:34.909 | ERROR | Thread-3 | s485.JSerialCommPort:71 | Could not open port com0! com.fazecast.jSerialComm.SerialPortInvalidPortException: Unable to create a serial port object from the invalid port descriptor: /dev/com0 at com.fazecast.jSerialComm.SerialPort.getCommPort(SerialPort.java:502) ~[jSerialComm-2.10.4.jar:2.10.4]

The BMS in particular is a JBD SP24S004

[ai-republic]

Well, you are using JBD_RS485 BMS binding so you should have the JBD connected via the RS485/CAN port to your Waveshare RS485 hat.
If you are using RS485 on the RPI then your port should definitely not be /dev/com0. Your serial ports would be named /dev/ttyS0 or /dev/ttyAMA0.
Could you share your config please?

Ok, thanks. I see a few possible issues in your configuration.
According to your configuration you have 2 JBD BMSes connected to one RS485 port on your Waveshare RS485 hat.
Have you configured the ID each JBD on the BMSes? Usually via DIP switch. The must match your configured BMS ID 1 and 2.
As mentioned above on the RPI your port should definitely not be com0 and com1. Your serial ports would be named /dev/ttyS0 or /dev/ttyAMA0.
Are you using this RS485 hat: https://www.waveshare.com/2-ch-rs485-hat.htm? Then your serial ports should be /dev/ttyS0 and /dev/ttyS1.
Please try these ports and for testing please configure log level debug, NONE as inverter and also no extensions or plugins.

[bmat8]

Ahh using this one in particular:
https://www.waveshare.com/2-ch-can-fd-hat.htm
I will give it a try in a few hours.

[bmat8]

Okay, so I am running CAN ports, though unsure what I would put in the config file. I used the instructions from here, however, I am able to have the two successfully talk to one another. Any ideas what needs to be put in the config file?

Hmm, you're trying to run the JBD via RS485 on a CAN port. That won't work. RS485 and CAN devices use a different physical communication layer.
I don't have a JBD CAN protocol communication specification yet. If you can get hold of one I could implement it.
You're only other option would be to buy a Waveshare RS485/CAN hat i.e. like this one: 2 x RS485 + 1 x CAN or you can stack this on top of your CAN hat: 2 x RS485
Another thought: can you configure the JBD to use a different protocol specification, i.e. Pylon, SMA, etc?

[bmat8]

Ahh, JBD bms doesn't have that option from what I've been able to find using quite a few apps linked to the bluetooth module. I did find an article from a few years ago that describes how their CAN protocol works (proprietary) but will have to find it again. Unfortunately, cleared my cache/cookies/history two days ago so no browsing history available. In the interim, I did buy the 2xRS485+1xCAN.

[bmat8]

Progress with the new module but not quite there.

Picture of the RS485 port on my JBD BMS as well:

Currently only running RS485A/RS485B to the two ports. Not sure if I need to add a ground and where from.

[ai-republic]

Ok, the configuration looks good. You connected the 485_A and 485_B pins of the JBD to the RS485_0 A and RS485_0 B connector port on the hat? Ground is not necessary.
I added reading the cell voltages and more debug logging. Could you please do a Clean install and attach the log file here?
Please configure only one JBD BMS, set the log level to debug, set inverter to NONE and no extensions, so we get only the data from the JBD and the log file is better readable.

I've been debugging this and it comes down to being a checksum error. The checksum calculation seems to work for the JBD v4 protocol but differs slightly for the response you get from your JBD. Still need to look further into this. It would help if I get a longer log (please attach the file, not paste the text here) so that I can try and check with different commands

Attached longer logs this time.

Thanks, will have a look at it in a couple of days 😄

Not a worry. i wound up switching out the JBD for a JKbms as the JBD wound up dying out of nowhere. Always had issues with it unfortunately.
