Hex Protocol for SmartSolar MPPT RS450

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.

Hi,

On our technical documentation page (here) there is a document called "VE.Direct HEX Protocol MPPT". This also applies to the SmartSolar MPPT RS.

Kind regards,

The VE.Direct description only applies to "BlueSolar and SmartSolar MPPT chargers". I can take over many addresses, but some important ones are missing. E.g. the 450 RS 450/100 has two trackers. I need the panel voltage, current and power for both trackers.
