Hi Just want to bump this thread to see if you got your BMS working correctly with Solar assistant? I currently have 2x 5kw Super Infinisolar (SOL-I-IS-5M) and 2x Dyness B3 3,6kw units and i am struggling to get the correct SOC and BMS going on the software... I have tried to communicate dirctly with the battery, and what i have figured is that the DIP switches are in reverse according to my tests??? Dyness manual gives the following: Dip1 - BAUD rate selection, ON is CAN250K or 485: 115200, OFF is CAN500K or 485: 9600 Dip2 - RS485 selection Dip3 - Select the Master unit Dip4 - nothing What i found when communicating directly: Dip1 - nothing Dip2 - Select the Master unit (set to 1 for master, set to 0 cant communicate) Dip3 - RS485 Selection (0 gives RS485 Comms in my tests) Dip4 - BAUD rate selection, ON is CAN250K or 485: 115200, OFF is CAN500K or 485: 9600. (0 gives 9600 comms and 1 give 115200 comms) This is what was read directly: RS485 Comms on 9600,N,8,1,0 [08:52:43] <= Response: 01 03 FA 00 00 14 32 00 64 00 64 1D 4C 1D 4C 1D 4C 00 0D 00 00 00 00 00 00 0C 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 02 17 00 00 01 77 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 78 05 [08:52:43] => Poll: 01 03 00 00 00 7D 85 EB Screen shot is attached. I am going to try these settings tonight on my batteries and see what the software pics up. I have been talking to Pierre as well from Solar assistant, so i will let you know when i get any answers. I have purchased 12x 480W solar panels and 2 more 3.6kw dyness so im really hoping to get the software working well with the BMS system so i can integrate well with home automation and so on. My current solar assistant setup does not read the BMS properly and does not show the 2x batteries seperately i currently have. Also, when i pull a mere 1 kW for 1 hour it drops my SOC to 50 odd percent which is not the case, therefore i suspect the unit is reading the voltage and converting that to a SOC value, instead of actually reading the true SOC condition. Will keep you posted.
