OK I’m working on my system that incorporates a multiplus 2 48 V DC charger a lynx smart BMS 500, a Cerbo GX unit and multiple smart shunts as well as a BMV 700 digital gauge. This is all the Victron equipment I’m running.

In my circuit I have the BMS 500 connected to my charger, and when I enable the BMS 500 on I hear the contactor close yet I keep getting faults and charging current is not going to my batteries. The fault codes I am getting are W- B06 and W-B01.

In my troubleshooting manual it says that this might because of low battery voltage this wouldn’t make any sense because this whole circuit is designed for charging batteries that are low on voltage, so did I choose the wrong equipment and do I need to find another contactor? because that’s all I’m really using the lynx Smart BMS for not primarily for BMS monitoring. I have my own BMS monitoring system through Vero energy.

Please help me. I am an electronics technician, but I am stuck at the moment.
