5. Installation
5.1 Site Selection and Preparation
- Do not install the battery pack on flammable building materials.
- Install the battery box at eye level for easy LCD display readability.
- Maintain an ambient temperature between 0°C and 55°C for optimal operation.
- Install vertically on a wall.
- Ensure sufficient heat dissipation space and wiring removal space (at least 20cm/7.8in on sides and 50cm/19.6in above/below).
5.2 Mounting Steps
Figure 5: Illustration demonstrating the recommended installation method for the DATOUBOSS battery, including wall mounting steps and clearance requirements.
- First, fix the mounting bracket to the wall using expansion screws.
- Next, fix the bracket to the back shell of the battery unit with short screws.
- Finally, hang the battery unit onto the wall bracket.
Note: This installation method is only suitable for concrete or other non-flammable surfaces.
5.3 Parallel Wiring and DIP Switch Configuration
When connecting multiple battery units in parallel, proper DIP switch configuration is essential for communication and address assignment.
Figure 6: Diagram explaining the DIP switch settings for addressing multiple DATOUBOSS battery units in a parallel configuration, along with a table of address assignments.
When connecting battery packs in parallel, use the DIP addressing function. If DIP6 is connected to ON, the system will use automatic address assignment. Otherwise, use the default automatic addressing function. The DIP switches on the BMS are used to set the address to distinguish different data packets.
Refer to the table in Figure 6 for specific DIP switch settings for each battery unit (PACK1 to PACK15).
6. Operation
6.1 Powering On/Off
- To power on, ensure all connections are secure, then activate the external air switch and press the internal push button switch.
- To power off, reverse the process: press the internal push button switch, then deactivate the external air switch.
6.2 Monitoring via Touch Screen
The integrated color touch screen provides real-time monitoring of battery status and parameters.
Figure 7: Image showing the color touch screen interface of the DATOUBOSS battery, displaying real-time monitoring data such as voltage, capacity, current, and state.
