Battery module address:It is used to set the master and slave of the battery module.
RS485
R485: For communication between battery system and inverter.

CAN1&CAN2: For communication between battery modules.
Power terminals (+) & Power terminals (-)
The total current shall not exceed the maximum value of 100A carried by the connector.
Power terminals: It is used for paralleling between battery modules and connecting the input
terminals of inverter.
Definition of ADD
When the stack of battery modules is completed, confirm that the top battery module is the master.
A battery energy storage system has only one master and several slaves.
Digital representation of dial switch: ON represents 1, OFF represents 0.
The first digit is to identify the master and slave. 1 represents the host and 0 represents the slave.
The three digits on the back of the master represent the total number of battery modules.
The three digits behind the slave represent the slave number.
As shown in the figure, the first digit of dial switch is 1, it means that the battery module is the host,
the last three digits are 101, it means that the total number of battery modules is 5.

2. Safety Requirements
2.1 Responsibilities of the installer
The installer must ensure that:
1. Before installation, the installer should read and understand this manual.
2. The protective equipment shall be complete during installation
3. The unclear warning label on the battery module should be replaced immediately
4. Make sure there are no inflammables near the battery module
5. Before installation and operation, be aware of any potential hazards and conduct necessary
risk management on site.
6. Do not change any components of the battery system without the approval of the manufacturer.
7. The battery system is damaged due to unauthorized modification of components, and the
warranty is invalid.
When handling battery module, pay attention to the following aspects:
1. Remove the watch, ring and other metal products;
2. Use tools with insulated handle;
3. Wear rubber gloves and labor protection shoes;
4. Do not put tools or metal parts on the battery;
5. Do not touch the battery module with wet hands.
6. Do not crush, drop or puncture the battery.

7. Always handle battery module in accordance with local safety regulations.
8. Do not transport battery modules without packaging.
2.2 Requirements for the installation environmental
The installer shall ensure that the installation position meets the following conditions:
1. The installation position must be kept dry.
2. The ground bearing capacity should be greater than the whole battery system.
3. Clean up the sundries near the installation position.
4. Keep away from highly inflammable and explosive materials during installation.
5. Keep ventilation.
6. The battery system is best installed in a place that do not affect users.

4. Installation steps
4.1 Check the package
The battery system has been carefully inspected and packed before dispatch. But it is still
possibly be damaged during transportation.
1.If the external package has been damaged, it is possible the device or the internal components
have also be damaged during the transportation.

4.2 Battery module matching
There are labels on the carton and the battery box, which are ①and ②respectively. When
installing the battery system, only ①and ①can be combined, and ①and ②cannot be
mixed.
4.3 Unpacking steps
①Open the carton and take out the sponge.
②Take out the side cover.
There is a latch inside the side cover. Open it as the picture.

8
③Grab the handles on both sides and take out the battery module.
4.4 Check the battery modules status
Before installing the battery system, we need to check the current status of the battery module.
Preliminary inspection
1. Before starting a single battery module, the dial switch should be set to 1001.
2. Open the breaker.
3. Press the start button until the green led is on.
4. Observe the LED indicator. After starting, the green light will be on for one second and then
off.
5. When the green light is off, the battery will enter the self-checking mode, and the battery will
be started when the battery parameters are normal.
6. If the battery parameters are abnormal, BMS will disconnect the breaker.
7. If the battery module does not start normally, please contact the distributor to replace it.
4.5 Battery modules stacking and fixing
The capacity expansion is realized by stacking the battery modules. As shown in the figure,
usually we stack 4 modules. If you want more modules to stack, please consult the manufacturer.
NOTE: The metal base under the battery modules is optional.
