I have a Epsolar Tracer 1210AN charge controller that I trying to configure for an Arduino Uno. I’m using a RS485 interface. I can’t find any setup info for 1210 controller. My issues:
I don’t know the correct pins to use from the controller’s Ethernet connection to the RS 485 board. I’ve tried 2 and 3.
I’m not sure what the Slave address would be. I’ve tried Address 1
I’m not sure what the register addresses are that give me the info from the charge controller (Voltage, Current, Etc.).
My code compiles fine. I’m just getting juke on the serial monitor.
Thanks for the help.
