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?

This is to let everyone know of a bug in firmware... Main CPU version 69.05 and secondary firmware 12.21. When charging off solar only, everything appears to work correctly. The same is true when charging off the grid power. The problem is when trying to charge off both AC grid and solar at the same time. What happens is everything works correctly if AC grid power is first applied and then solar power, both sources charge the batteries. However when solar is first applied and then AC grid, only solar is charging the batteries. This is the bug in firmware. 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 I am using 4 of the 5.14 KW OP solar batteries in parallel,
