I am having problems getting the OP batteries to communicate to the OP inverters. I have the 4 batteries connected in parallel and ethernet cable connected between the RS485B ports of the batteries. All the address DIP switches are set to address 01 to 04. I also have a cable between the 01 battery of RS485A port and the master inverter in my system. This cable is connected to the BMS port on the bottom of the LCD display. Right now I am using the following settings. The settings in my inverters are....

Program Setting

01 01 or USb

02 80A

05 05 or USE

11 20A

16 16 SNU

26 57.6V

27 54.1V

However, when I try to get the batteries communicating to the inverter by changing program 05 to LIB or LIC, I get a communication error. Any ideas on what I am doing wrong?
