I'm reaching out to clarify some connections on my inverter and battery setup. My inverter has a small RS232 terminal and a larger terminal labeled BMS. I need to know which of these terminals should be connected to my battery, which features RS485A, CAN, and RS232 terminals, all of which are large. Additionally, I want to ensure that I'm setting everything up correctly, as I didn't receive wiring instructions with the inverter purchase. Your assistance in detailing the proper connections would be greatly appreciated. Thanks!
