5.4 Battery Management System（BMS）
5.4.1 Overcharge Protection
When the voltage of any single cell or whole battery pack is higher than the set value during the
charging, and the duration reaches the limited time, the system enters the over charging protection
state automatically, the charging MOS is turned off at the same time, and the battery cannot be
charged. After the voltage of each cell and the whole battery pack drops below the cell over charging
recovery value, the over charging protection state is released. It can also be released by discharging to
return to normal state.
5.4.2 Overdischarge Protection
When the voltage of any single cell or whole battery pack is lower than the set value during discharg-
ing, and the duration reaches the limited time, the system enters the overdischarge protection state,
the discharge MOS is turned off, and the battery cannot be discharged. After the overdischarge
protection of the battery pack occurs, it can be released by charging the battery pack.
5.4.3 Overcurrent Protection
During charging and discharging, when the current exceeds the set value of the protection current,
and the duration reaches the limited time, the system enters the overcurrent protection state, the
charging and discharging MOS will be turned off automatically, and the battery cannot be charged and
discharged, charging and discharging the battery pack can release the overcurrent protection state.
5.4.4 Over Temperature Protection
When the NTC detects the temperature of the battery cell surface is higher than the setting value of
over temperature protection during charging and discharging, the management system enters the
over temperature protection state, the charging or discharging MOS is turned off, and the battery pack
cannot be charged or discharged in this state.
5.4.5 Low Temperature Protection
When the NTC detects that the temperature of the cell surface is lower than the setting value of low
temperature protection during charging and discharging, the management system enters the low
temperature protection state, the charging or discharging MOS is turned off, and the battery pack
cannot be charged or discharged in this state.

Support up to 8 units stacked

6.2 Installation Procedure
a. Use a multi-meter to measure whether the positive and negative cable wires are conducting, and
check whether the positive and negative terminal connections are loose.
b. The battery should be switched off before wiring to ensure that there is no DC output from the
battery.
c. Connect postive terminals of the battery and the inverter with red power cabel, and then connect
postive terminals of both side with black power cable.
d. Connect both conmmunication ports of the battery(RS485A/CAN) and the inverter(BMS port) with
the comminication cable, BMS ports of inverter have different definition for some brands, pls check
inverter manule.

7.3 Dip Code Switch Definition and Setting
ADD switch is an 8-bit DIP switch to manually distribute the communication address of parallel
batteries.
The BMS will only recognize the DIP address once it is reset, so please reset the BMS when the DIP
address is changed (the BMS must be reset in the standby state). When the DIP address is 0, the
battery is configured as the stand-alone working mode; when the DIP address is 1, the BMS is
configured as the master working mode; when the DIP address is 2 to 6, the BMS is configured as the
slave working mode.
Please refer to the table below to set the DIP switch for parallel connection of different batteries.
