Good day, I have 4 Hoselect 48V 100A Lifepo4 wall mount batteries paralleled. I have communication from my SPF5000es Growatt inverter to the first battery. I need to establish coms between batteries. I connected pin to pin cables from RS485A on battery 1 to RS485B on battery 2 and then from battery 2 RS485A A to RS485B on battery 3 and so on. I am not sure they communicating as I have different discharging and charging on the batteries. If I set dip switches all on master battery settings the inverter shows BNS communicating but the moment I change dips witches on batteries 2,3 and 4 as per manual the Inverter screams and loses coms with batteries. Any help on the cables pin configure and dip switches to meke sure all are communicating will be appreciated. My inverter uses BNS to CAM connection pin to pin Thanks
