Hello!, I have two Pylontechs UP2500 ("24V" 100Ah) and I am currently calculating the SOC with an external shunt and a raspberry pi.
My SOC solution is inaccurate so it syncs to 100% whenever the system is full. Yet if a whole week passes by and the battery oscillated (ie between 20% and 75%) not reaching full capacity, the SOC may drift more than 15% after those few days.
My inverter is not compatible with the pylontech bus (nor does it feature ANY kind of connection to any battery). What I'm wondering is if I could connect my RPI to the batteries and read the SOC (and some other useful data, maybe?)
This is from the manual:
If get this right, I should be aiming at the RS485 interface. Would you recommend me getting an RS485 to USB adapter and see what I can get ? I have a feeling that I won't be able to get my hands on a proper command list.
So... what do you think ?
Thanks for any input and regards!
