This is the west- north string and this is South + East strings in parallel, both in a cloudy day with a very short spike of sunshine, between -4 and 0deg C outside :

Anyone around that can share te MSDS report ? that should be a public information

Hello, Is anyone around here that has successfully updated the firmware of MPP Solar 8048 MAX inverters to solve the issue it has in the cloudy mornings, where it keeps the DC voltage to low FOR TO MUCH TIME ? It keeps the voltage at 90v way to much time, some people find out that if they...

Yes, I do have an MPP Solar 8048MAX inverter and ANT BMS, but I didn't had more time to try to connect to ant bms with ESP8266, a friend of mine just received the BMS, and he also want's to use an ESP32 board to connect to the BMS, I-ll tell him to join the forum and post back his code/ or the...

I don' think we must reverse engineer anything, the communication protocol documentation is available, we need just free time, something I don't have :( .. and while the rPi Zero is working, I try to finish my other projects first, and only after that work on modifying already working projects.

I also plan to use an ESP.. but didn't had time yet to try again with an different BT module. With the only BT module I had, I was stuck when I tried to detect the ANT BMS BT Address, I got ERROR (16) as I described on the arduino forum

do you have python-bluez installed? , if not install it using : sudo apt-get install python-bluez

Hello everyone, after seeing the diagrams posted in the first pages, I made an precharge circuit for my battery too, I used the resistor that I recovered from the original Hyundai Ioniq 2018 Battery (I disassembled an entire battery and reconfigured it in 6p15s). Thank you for the diagrams.

Anyone knows the reason for this inversion made in the code ? I can modify the code, but I want to know why @chadhouser made that inversion. I don't know yet what is the raw value of the power, but I will try to find out myself when I will also start discharging the battery. I believe...

Here is the modified code, I also confirm all 4 Cells temperature sensors work, the sensor 3 and 4 use the 100 and 102 pointer , as in the attached file. Here is the return of my code, and the request from apache local server pi@raspberrypizero:~ $ sudo python /home/ant-bms-bt-to-http.py...

Thank you guys for the python code posted in this thread, I also want to port it to arduino but currently I had some issues with my HC-05 module and I gave up trying with arduino, so I grab a spare Raspberry Pi Zero w and happily after a few hours I was able to talk to Ant BMS module. I...
