By the way , Kindly Reminding：Please order "other accessories " when you order master bms and slave bms since
"other accessories " include precharge relay ,charge relay, discharge relay , ON-OFF switch relay,RS485-to USB Converter,
Pre-charging resistor ,Shunt , Fuse ,Photovoltaic anti-reverse diode , Diodes , Balancing wires ,Emergency Stop Button , Start Button, etc.
High voltage box need to be gounded ;Inverter need to be grounded;Battery case need to be grounded;

Configuration for Different Inverters and flash Inverter protocals into Master BMS
(DEYE/GOODWE/ATESS/SOFAR/INVT_BD/PYLON/GROWATT/MEGAREVO/KOYOE)
Master BMS is used to configurate the charging cut-off / discharging cut-off /Over current cut-off / Balance starting /Inverter
Communication / Inverter charging cut-off / Invert discharging cut-off /Cell strings ,etc. Let me take BMS 48S for example ,
please see the following configuration
Attentions :for slave bms 32 S , you need to do setting in the pc software in this way : slave bms 32s = 2* slave bms 16s ; you need to enter 8 at Pack Nums+2 * 16 at Cell Nums + 2* 3 at Tempr Nums;
Entering 4 at pack Nums +32 at each Cell Nums +6 at Tempr Nums is not allowed ; BMS cannot work ;
Take 128S for example : you need to enter enter 8 * 16 at Cell Nums + 8* 3 at Tempr Nums;

HV BMS Monitoring System
Before you set /calculate SOC , please enter password: AF123456;
How to get correct SOC now?
Set the design capacity / full capacitu / residual capacity in the pc software as below ;
regarding the residual capacity , please enter 1/2 full capacity
and then take a complet cycle of discharging and charging ; finally the SOC will be calibrated automatically

you need to change the settings of converter via RS485 transmission cable ; if not , the converter cannot work properly
If you use slave bms 32s , please don't enter " 32" and "6";
you shall enter " 16 " and"3"+"16"and "3"
Attentions :for slave bms 32 S , you need to do setting in the pc software in this way : slave bms 32s = 2* slave bms 16s ; you need to enter 8 at Pack Nums+2 * 16 at Cell Nums + 2* 3 at Tempr Nums;
Entering 4 at pack Nums +32 at each Cell Nums +6 at Tempr Nums is not allowed ; BMS cannot work ;

Master BMS Firmware Update :
you can flash the protocals /bin files into master bms
Battery capacity Settings in the BMS Monitoring Systerm Software
Slave BMS DIP CODE ： each slave bms has one dip code ; the rule as following :
How to connect bms to Deye Via cabus communication ?, please see below :
1. First of all , you need to select " PYLON-HV 派能(500K)"
2.Please use RJ 45 cable to connect master bms to BMS port of DEYE
PIN Definition of BMS PORT of DEYE
according to above pin definition of bms port , you can see that only 2 cables of CAN -H and CAN-L are kept for connection between master bms and DEYE ; please see below
CAN-H and CAN-L at BMS port of DEYE
CAN-H and CAN-L at J2 port of Master BMS
afterwards ,you need to connect Cable of CAN-H and CAN-L of master bms and Cable of CAN-H and CAN-L of DEYE together
and then connection between bms and deye is completed ;
Finally you need set "00" in the battery mode of DEYE
