  • 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;

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:

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

Let me take 96S and 128S for example , please see following :

 

If lifepo4 battery 128 cells in series , please do setting in the following way :


Step 1: Select  "128S +8 bmu(16s)" and then press the button "Load”

Step 2 :After you press the button"Load ", the settings are automatically loaded from the sysyem,but these settings are just used for lifepo4 batteries (If you use Li-ion NMC battery/LTO Battery , you need to do settings by yourself ) ; Afterwards ,you need to press the button "Write" and "Read" seperately
