3. Battery bank wiring
If battery balancing does not have the required effect and the voltage difference becomes larger than 0.2V, the battery unbalance is larger than the battery balance can correct. This is most likely an indication that one of the batteries has developed a fault and the Battery Balancer will sound an alarm and it will activate its alarm relay.
