Seplos CAN BUS RS485 48v 200A 8S-16S BMS

but rs485 is a physical layer
RS-485 does not define a communication protocol
so i think you cant communicate over that port at all never
so even if you ask seplos to change to rs485 they cant do it hopefully i am wrong

see
https://en.wikipedia.org/wiki/RS-485 ===> hardware connection

and the communication protocol
https://en.wikipedia.org/wiki/CAN_bus ===> software portion

ask MPP Solar what the communication protocol is on that port

rs485...

and i very well know what the phy layers are.
but again, this is a dual identity port, so i suspect the port is connected to both a serial and canbus chip, where they have disabled the can bus for what ever reason.

my point exactly on why to pursuade the bms manufactorer to update their firmware.
the bms had both active and present, it just that their itteration of the pylontech protocol now only runs on their canbus port
 
Just noticed this oddity on their wiring diagram. Anybody know what to make of this? Do they want me to connect the positive to more than one of the terminals for some reason?

Physically, the board looks like this:

Are they worried that one of the lugs can't carry enough current through the board?
Yes, one terminal cannot carry enough current. You're supposed to connected all the terminals with P+,P-
 
thanks for the links!
, unfortunatly voltronics simple hasnt made this available in any of their firmware, because they consider it "reserved"
Also , my inverters ( 8000MAX ) don't seem to have any new firmware avail. , unlike the 7200max
The 7200max is what MPP rebranded as the LV6548 correct? I know MPP derated it for some reason, but dunno why.
 
I have installed this BMS and it’s working but I am lost as to where to find the management software for a windows PC/ desktop. Can someone please provide me a link? Thanks in anticipation.
 
I cant get any of these files to run? I can open them but the .exe files will not run. I am using Windows 10. Any ideas or is there another link somewhere. Thxs.
Any errors? Try to right click and run as admin.
 
i am running as admin and I can open and read what’s in the file but I can’t run or execute them When I try to right click the files inside the zip file there is no response…..no drop down options. I have also done a restart of the pc.
 
It is necessary to download the file to your computer, unzip it with any archiver, and then run the executable file .exe
