● If the battery string is congured with the neutral wire, measure the currents of the positive
and negative battery string cables. If the battery string is not congured 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
congured with the neutral wire as an
example.
● When an iBOX manages multiple battery strings, rst connect the Hall eect sensors on the
positive and negative cables of battery string 1 respectively to the corresponding ports on
the iBOX. Then connect the Hall
eect 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
eect sensor, or the measurement range of the Hall eect sensor is not enough, use multiple
Hall eect sensors to monitor the current of one battery string. The iBOX supports the sum
of the monitoring results of multiple Hall eect sensors, which is set through Multi-Hall cur.
setting.
● The value of Multi-Hall cur. setting equals the number of positive or negative Hall
eect
sensors in a single battery string and should be greater than or equal to 1.
