I've been having some issues connecting my battery monitor to an orange pi for solar assistant. The battery monitor I have uses a RS485 connection.

and none of them can connect. (aside from inverter values and emulated bms of course) The either say invalid response or no response. I have also tried reversing the A and B connections. This is the battery monitor I'm using:
