5.7 B-Plus 2.5 address switch introduction
After finished the battery installation, installer should setup battery address by “ADDR” switch.
“ADDR” switch introduction:
Function: Communicate between battery and BMU, BMU will communicate with external
equipment when use CAN communication.
Each DIP switch definition:
There are 6 bit switches, keep the switch on down side means”0”, turn up the switch to “ON”
means “1”.
Address: 000000 Address:100000
For example: when two battery in using, “ADDR” setting:
No.1 battery address: 100000 No.2 battery address: 010000
Please refer to the configuration list in Appendex1.
Notice: Make sure of the highest address of BMS connecting to BMU which communication with
inverter.

6 Cleaning and maintenance
6.1 Cleaning
The B-BOX system is recommended to be cleaned periodically. If the enclosure is in a dirty
condition, please use a soft and dry brush or a vacuum to remove the dirt. Do not use liquids such
as solvents, abrasives or corrosive liquids in the enclosures.
6.2 Maintenance
6.2.1 Recharge requirement with normal storage
The B-BOX should be installed in position with the temperature range of -10
℃～
+50℃.The
load-bearing of battery’s package is less than 300Kg, So don’t let more than 7 modules in stack.
When the battery stored for a long time, need a regular maintenance according to the following
table Charge battery with current of 0.5C (25A) for 1 hour when maintenance.
