I agree with you 100%... I now set the charge current to 0 when the SOC passes 95% otherwise the BMS starts sending a whole bunch of incorrect stuff out. Chances are good that I just don't understand it as well...

Hi Lindsay We did... Its not 100% yet, but it is working most of the time. The serial/uart comms to the Raspberry Pi works fine, but like @JustinSchoeman also mentioned, it spits out dodgy data every now and then. From the Raspberry Pi we had to add a CANHAT to the RPI, and then we went the CANBUS method. The code is a bit messy, I am not a programmer by trade so you can imagine where this is going. I have odd bits and pieces in there to control my pool pump ect... You can check it out here: https://github.com/tomatensaus/bms Regards

I had the same issue... Turns out, and this is what the Tshwane Electrician told me, was that the electricity from the inverter, and the electricity from Eskom will have a phase difference, and that causes the meter give the errors. I installed a "on grid" plug in the garage which sorted out the issue... Its also handy if you have large tools that you like to run, which then doesn't have to start up on you inverter/panels/battery

Thank you... I am a complete noob at this sort of thing, but I figured i’d give it a shot, and the Arduino and other bits are on the way from China... I am also working with a mate on a python/raspberry pi project to try see if that will work. So far we have managed to establish comms between the BMS and the Pi. Next step is to Establish comms with the inverter, and then mimic another battery much like you did.

Hi Justin 150A Daly Smart Bms. Happy New Year everyone

Hi Justin AWESOME WORK!! I would like to play with this. Problem is I have no idea where to start. I have just finished my DIY battery, similar to yours, 16s3p 120AH 2nd Life cells. I would like to be able to communicate with my Deye 8kw inverter. Where does one start? Regards
