as I said on meterN threads, I developed a C program to read EASTRON SDM120C RS485 meter.
This meter could be used also to read PV production, for those inverters not directly supported, connecting it on AC inverter output.
Obviously, in this case, we would have only AC values, not DC.
So, here is 123solar protocol https://github.com/gianfrdp/SDM120C/tre ... /protocols
you can find also C program to read meter https://github.com/gianfrdp/SDM120C.
I hope this could be useful.
