I'm currently working on reading the data from an MPPT 150/35 charge controller onto my raspberry pi. The purpose is to use the data I get to analyze the performance of our solar car and improve the car's model accordingly.
So far, I have connected directly the smart V.E.-USB dongle into the pi and asked it to read what the controller is spitting out (using a cat /dev/ command). The problem there is the output I'm getting is nonsense (or likely in some other 'language' that I do not know how to decode). I will link a picture showing specifically what I am getting.
Is there a certain library or method to directly talking to the 150/35 charge controller and sending it commands to output the solar panel's instantaneous data? And if I have done this correctly so far, is there some source code I can use to actually make some sense of my current output?
In the ideal case, I would like to have repeated outputs saying: power consumption _, current drawn_, voltage_, etc.
(For reference, I'm working in python.)
Any help would be greatly appreciated! Thanks!
Using my Mac as a shell, I got the following outputs:
