Hi all, I’m in the process of building some software for inverters, the end goal is to support multiple inverter types and batteries. I have some great ideas of my own but wanted to get some perspective from the peeps in here that already have solar setups, and wanted to see what your pain points are and if you could build some cool software, what features would you add?

So I wrote a custom logger for my data, which pretty much logs the data it retrieves every second, and it reads the following: Timestamp Solar_pv Voltage_grid Voltage_inverter Load_grid Load_inverter Battery State of Charge Battery Voltage Battery charge volts so it's quite basic just pretty much anything related to power coming in and out the inverter, the goal is to find trends and link the weather conditions/time with the power coming in and make some decisions off of that, the formatting of the data doesn't really matter, I can cleanup and try make use of whatever I can get my hands on. Would also be helpful just mentioning the setup your on, panel specs, inverter specs etc... Much Appreciated :)

Hi all, I hope I'm posting this in the right thread, hoping someone could help me out with this. I'm currently doing my thesis for my Computer Science degree, on improving reliability and solar utilization with IoT and Machine Learning, and need to construct a few machine learning models for some experiments, and I need as much data as I can get my hands on, I have been collecting some data of my own from my inverter, but it won't be enough, so if there is anyone here that has some data recorded and is willing to send it to me, that would be awesome, you will be credited in my thesis. I would also just need the area of your setup so that I could track the weather patterns of that area and try correlate it to the data. Thanks!

I have a Pylontech battery that I am trying to read info from, and I've had some on and off success, I have a RJ-11 to RS-232 Cable and the Pylontech is connected to my Windows laptop for now, at a later stage I want to connect it to my Raspberry Pi 4, with a script that saves the info that is read from the battery, but I first need to understand the Pylontech CLI before I can start writing scripts to communicate with it. At first I tried using some Console emulators such as PuTTy, but I had no success, kind of, It looked like I was indeed getting a response from the battery, but it didn't look like the correct response, as far as I understood, I needed to activate the batteries console, by setting my terminal program settings to 1200, 8,N,1 and then sending the following hexadecimal string 7E 32 30 30 31 34 36 38 32 43 30 30 34 38 35 32 30 46 43 43 33 0D after sending that string, I got the following response: ~200146060000FDAD ~200146060000FDAD I tried messing around a bit more but I kept on getting this same response, I then found the BatteryView application and started to use that for a temporary solution, and it works perfectly fine, but it still doesn't completely solve my problem. Today, I tried to connect via a terminal program again, and I had some success, I changed the terminal program settings to 1200, 8,N,1 and sent the hexadecimal string (7E 32 30 30 31 34 36 38 32 43 30 30 34 38 35 32 30 46 43 43 33 0D) but this time I got a completely different response, now I unfortunately didn't record that response but it had was a bunch of strange characters, I then proceeded to change the settings to 115200,8,N,1 and then I sent the 0D 0A hexadecimal string. Success! Finally, I had gotten into the Pytontech CLI and I was able to type commands like help, or bat to get some data, which was cool, but then my laptops battery had died, and when I rebooted to connect to the battery again, I had gotten the same responses that I originally got, which was: ~200146060000FDAD ~200146060000FDAD So I don't know if I just accidentally got something right and was lucky, or if I am missing some step, but the thing is, I got it to work, and now I'm stuck again at square one.

Just what I needed

I'm still a student and I'm interested in learning how to do this kind of thing so it would be beneficial for me

Hi everyone, I'm pretty new to solar systems and even IoT but I want to help my dad with his solar system, I basically just want to setup something that can read some parameters from the inverter such as Battery Voltage, Amperage, Wattage from panels etc... and then send that to a computer where I can put the data in a application and display it. I'm thinking of using a Raspberry Pi or an Adruino, can anybody link some good documentation on how I would be able to accomplish this since I am new to IoT and even using things such as a Adriuno or Raspberry Pi. I have programming knowledge in quite a few languages, I just don't understand how to read the parameters from the inverter to the Pi or Adruino and then send it to a computer so if anyone could perhaps explain or link me some documentation that would be great. Edit: Sorry I forgot to mention The inverter my dad is using is some sort of clone of the Axpert(4000W 48V)
