If installing
two batteries
, ensure that each battery has a
different part number
– thus ensuring that each
battery will have a different Battery ID. The part number is printed on a label on the control panel of the
battery. Battery with part number RXXXXXXXXSEG1XXXXXXXXX and ID 15 is the
master
battery.
Battery with part number RXXXXXXXXSEG2XXXXXXXXX and ID 14 is the
secondary
battery.
To configure the second battery:
Select Communication > RS485-1 > Battery 2 > Battery ID (14).
