3D drawings of Master BMS
3D drawings of Saster BMS
3D Drawing of Slave BMS .zipBy 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;
Wiring diagram of high voltage BMS with heating (REL5)/cooling(REL6)
Wiring diagram of high voltage BMS without heating (REL5)/cooling(REL6)
For better resolution of bms diagram ,please check the inserted PDF file;
Connection Diagram of HV BMS.pdf
Attention : when you do wiring , please check whether or not the ground of the DC-DC power supply is connected to the
housing of the high Voltage box, and the housing of the high voltage box should be grounded. And the case of all batteries
should also be grounded!
This bms can talk to inverter：
(DEYE/GOODWE/ATESS/INVT_BD/PYLON/GROWATT/SOFAR/MEGAREVO/KOYOE/SOLAX/SOLIS)
During assembly ,some points for attention
Please be sure that the inverter /High voltage box /slave bms go to be grounded ;
otherwise , the canbus communication distortion occurs
please be aware that each slave bms need to be grounded
High voltage box need to be grounded
Inverter needs to be grounded

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
What is the standby current ?
Standby current means BMS self power consumption which is 500mA ; Please enter 500 here ;Please see below :
What is the Zero Diff
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
How to calibrate the current ?
Please adjust the FL CHG/FLDSG factors if charge current discharge current is not in line with actual current
Before current calibration , please check if the setting of shunt is in line with the actual parameters of the shunt you use
How to set cell balancing in the PC software ?
