2. BMS Functions

Monitoring:
 
Voltage: total voltage, voltages of individual cells, minimum and maximum cell voltage.
Temperature: environment temperature, temperature of cells and BMS PCB.
State of charge: indicate the charge level of the battery.
Current: current in or out of the battery.

Communication:
 
CANBUS communication
Our BMS can support up to 16 units in parallel operation.
RS485 communication(RS485 can be customize)
 
When we want to view the battery pack parameters through the battery parameter monitoring software, we need to use the Rj45 to USB Adapter to connect the battery pack to the computer. We recommend that you purchase an Rj45 to USB Adapter from us.Adapters purchased from the market may not work properly due to the definition of the hardware
 
 
Protection:
 
Over voltage protection 
Capacity protection
Pre-chargeing function
Current limiting
Under voltage protection
Charge, discharge and ambient temperature protection

3. Communication methods

 
CANBUS communication method

Now our CANBUS communication board supports these brands of inverters,and our BMS has built-in CANBUS protocol of matching inverter brand, which can be automatically matched or manually switched:
 
The default is the Pylontech CANBUS protocol.

 
RS485 communication method

Now our RS485 communication board supports these brands of inverters,The BMS with RS485 communication has a built-in RS485 protocol, please confirm with the salesman before buying what you need is that one RS485 protocol:
