Hello,
I have been operating Batrium for about 8 years. From my point of view, Batrium BMS is a robust and reliable system and I am very satisfied with it.
But I have had a problem with connecting BMS Batrium via CAN bus to SolarAsssistant - on raspberry pi4 for a long time. Both Batrium BMS and SolarAsssistant have a CAN bus interface with battery profiles from Pylontech and I believe that they have them functional for real pylontech batteries. There is no doubt about that. But if I want to connect them and use the original cabling with the SolarAsssistant adapter and other adapters and converters, it does not work. When comparing the transmitted data with ID 0x351,5,6,9,0x35E, I compared their content and the ID at the output of the converters/adapters with the Pylontech standard. The data with their ID generated by BMS Battery corresponds to the Pylontech standard. And the data values corresponded to the real BMS parameters. At the same time, I tried to communicate with the BMS Batrium through the transmitted ID queries in the form 0x4200 8 02 00 00 00 00 00 00 00, where the BMS should respond and send a response in the form 0x7320 8 2D 00 03 0F 90 00 32 00. The BMS ID received it, but did not respond. I saw the communication process on WatchMon Toolkit 2.17.57 on the Pylontech profile.
And now I have a question, whether the Batrium BMS has a specified ID with values, which I insert into the can bus transmitter and the Batrium BMS will respond to me with an ID with a value, e.g. battery status. I now see in the data stream from Batria ID 0x35E 42 61 74 72 69 75 6D 00 (ASCII for “Batrium”), but I need to see that the Batria BMS receives data from SolarAsssistant.
I am also sending a screenshot of my settings “Batrium BMS settings and communication” with the data streams. And I can send “ExtractSetupSnapshot_SYS7389_20250630_193903” via email. Other ideas on how to get it working are welcome.
Use converters and measuring devices:
USB To CAN /RS232 TO CAN Serial Port Converter Adapter 232 CAN Bus Transfer Send (V8.00)
ECAN-101 CAN To Serial Protocol RS485 CANBUS Converter,CDEBYTE
ECAN-U01S CAN To USB Protocol Converter CDSENET
E810-RS-U01 USB To RS485,RS232 TTL Industrial Converter CDSENET
CAN bus USB cable from SolarAsssistant
