Unplug the "LAN" cable first before changing the parameter for RS485.
I just traced the pcb and yes, the can is on the right! I think I’ve made a huge mistake. ?Are you referring to this photo? Maybe this is why I’m unable to get CAN comms to a Deye Inverter.View attachment 185570
Is it possible that the balance wires need to be connected to retain the settings, JBD takes their BMS power through the balance leads.When removing battery power from the BMS, all the settings revert to default. I currently don't have any batteries hooked up yet, just a power supply to the B- and Bat+ just to play with the software and update the firmware.
Ok, so it’s the RS485-1 port in the photo? I’ll try that port later. what inverter do you have?I just traced the pcb and yes, the can is on the right! I think I’ve made a huge mistake. ?
Nope, I’ve my balance leads connected. Once BMS turns off the values reset to defaultIs it possible that the balance wires need to be connected to retain the settings, JBD takes their BMS power through the balance leads.
Yup - should, left to right, 4851, can, 232, 4852, 4852Are you referring to this photo? Maybe this is why I’m unable to get CAN comms to a Deye Inverter.View attachment 185570
That weird, I normally encounter sending failure if I have CAN or RS485 LAN cable connected.No LAN cable was plugged in when attempting this change. Honestly it's not a huge deal for me as I'll be using CAN, but was just testing. I think the RS485-2 port should be fine for computer comms as even if you have a stack of batteries you will always have a free port.
The manual kind of stinks. I’d like to know more about the heating function as this is the wire included. I’d like to know what the dc wires do and what the max rating is. Also I assume the green is a switched negative but also would like to know the rating.

I haven't found it, it's really new! If you get one, please tag me!Anyway of getting BMS data into Home Assistant? Is there a modbus address table available?
Well, another interesting thing I found. When removing battery power from the BMS, all the settings revert to default. I currently don't have any batteries hooked up yet, just a power supply to the B- and Bat+ just to play with the software and update the firmware. I have a 4s headway bank for testing 12v stuff and ordered another 4 to play with the BMS. I'll check it once I get those cells from batteryhookup. It would be terrible if this didn't have any type of memory storage.
