I'm new and inexperienced here in the forum, but I've been using the BMV 712 for 2 years. I read and set the parameters under Linux (C, C++) and the hex protocol. I use the document "BMV700 Series HEX Protocol". There are no problems with this. I have now acquired the "SmartSolar MPPT RS 450" and wanted to integrate it into my system, as with the BMV. However, I can't find any documentation on the Hex protocol for the MPPT RS. Where can I find this documentation? Without it, the device is worthless to me.
