5.3 Battery Management System（BMS）
5.3.1 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.
5.3.2 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.
5.3.3 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.
5.3.4 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.
5.3.5 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.

7. Connection
Communication cable connection Pin definition is as follows:
7.1 Precautions Before Connecting The Inverter
a. Use a multi-meter to measure whether connection of the positive and negative cables are
conducting, and check whether that 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 positive terminals of the battery and the inverter with red power cable, and then connect
positive terminals of both sides with black power cable.
d. Connect both communication ports of the battery(RS485A/CAN) and the inverter(BMS port) with
the communication cable, BMS ports of inverter have different definitions for some brands, please
check the inverter manual.

7.2 Precautions Before Connecting The Inverter with The Battery Pack in Parallel
a. Use a multi-meter to measure whether connection of the positive and negative cables are conduct-
ing, and check whether that connections are loose.
b. The battery should be switched off before wiring to ensure that there is no DC output from the
battery.
c. Lock the parallel cable wires to the positive terminal of the battery pack first, then connect another
end to the negative terminal.
d. Parallel communication cable to the RS485 port of the battery pack.
e. Connect positive terminals of the battery and the inverter with red power cable, and then connect
positive terminals of both sides with black power cable.
f. Connect both communication ports of the battery(RS485A/CAN) and the inverter(BMS port) with the
communication cable, BMS ports of inverter have different definitions for some brands, please check

7.3 Dip Code Switch Definition and Setting
ADD switch is a 4-bit/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.
