Hi any idea if this library will work with Renogy 10 Amp model? Also as you might know the Renogy controllers comes with RJ11/RJ12 port (not a standard 9pin com port). I haven't found any RS232 to TTL Converter that has RJ11/RJ12 port. what converter have you tested this with during your development? Thanks for your time

Hi, I do not own any 10 Amp model so I haven't tested them. According to this project: https://github.com/mickwheelz/NodeRenogy, they seem to use the same Modbus registers. As the controllers don't support standard RJ11/RJ12 pinout, you'd have to build your own adapter (see link above). I used a Max3232 mini RS232 to TTL converter along with an RJ12 cable. Let me know if it works!

hi, Thanks for quick response! so basically we need RS232 to TTL Converter plus com (RS232) to RJ12 converter/cable. And as to 10A compatibility seems hopeful, need to try my luck! Thanks again.

I didn't use a COM converter - just soldered the RJ12 connector to the RS232/TTL converter. Anyway, be sure to wire your pins correctly!
