● If the battery string is configured with the neutral wire, measure the currents of the positive
and negative battery string cables. If the battery string is not configured with the neutral
wire, measure the current of either the positive or negative battery string cable. The
following uses the scenario where the battery string is configured with the neutral wire as an
example.
● When an iBOX manages multiple battery strings, first connect the Hall effect sensors on the
positive and negative cables of battery string 1 respectively to the corresponding ports on
the iBOX. Then connect the Hall effect sensors on battery string 2 to the iBOX in the same
way, and so on.
● If the positive or negative battery string cable is too thick to be routed through the Hall
effect sensor, or the measurement range of the Hall effect sensor is not enough, use multiple
Hall effect sensors to monitor the current of one battery string. The iBOX supports the sum
of the monitoring results of multiple Hall effect sensors, which is set through Multi-Hall cur.
setting.
● The value of Multi-Hall cur. setting equals the number of positive or negative Hall effect
sensors in a single battery string and should be greater than or equal to 1.
