1 Product Information
1.1 Battery Overview
The battery is a wall mounted lithium battery pack which consists of long span LiFePO4
battery cells and functional BMS. It can store and release electric energy based on the
requirements of the inverter controller. It is mainly for home energy storage system.
Features
LiFePO4 prismatic cell
＞6000 cycles @0.5C conditions
Maximum 1C charge and discharge capability
Wall mounted IP 65 grade
Be extended to 8 packs maximum
Protective and active BMS allows greater reliability and control
Building in terminal design
Fully recyclable at the end of life
Compact

(1) Wall mount
Please mount bracket on the wall by six M8 bolts firstly. Then lift battery and stuck
with bracket.

(2) Wiring block
2P (1P positive and 1P negative) power interface, printed by "+" and "-",
front-mounted wiring method, positive and negative terminals are insulated by
thermoplastic polyester (PBT) insulating sheets.
(3) Switch
BMS switch, when it is turned off, the BMS can be put to sleep and the charge and
discharge MOS transistors will be turned off at the same time; normal operation
will be restored after it is turned on. Note: Please do not turn on the system switch
when the product is not in use to avoid self-consuming the lithium battery.
Version 1：CAN2.0B/RS485
(4) CAN2.0B COMM to inverter
BMS supports the function of CAN communication for battery pack uploading，
baud rate of 500K. CAN communication interface adopts 8P8C network cable
interface. It can communicate with inverter or CAN TEST through CAN interface.
When the battery pack is connected, RS485 communication is connected，the data,
status and information of the battery pack can be uploaded to PCS through CAN
communication.
