- It should be installed on a solid surface.
- It is recommended to install the battery box at eye level for easy LCD display readability.
- 最適な動作のためには、周囲温度は 0°C ～ 55°C の範囲にする必要があります。
- It is recommended to install vertically on the wall.
- Ensure sufficient heat dissipation space and wiring removal space (at least 20cm/7.8in from sides, 50cm/19.6in from top/bottom).
Figure 5: Illustration of recommended clearances for wall-mounted installation, showing minimum distances from surrounding surfaces for proper ventilation and access.
4.2 Installation Steps (Wall Mount)
- First, fix the mounting bracket to the wall using expansion screws.
- Fix the wall-mount brackets to the back shell of the machine with short screws.
- Hang the battery unit onto the fixed wall bracket.
Note: Only suitable for installation on concrete or other non-flammable surfaces.
4.3電気接続
Connect the positive and negative battery cables to your inverter or load according to the inverter's manual. Ensure all connections are secure and correctly polarized.
WARNING: Incorrect wiring can cause severe damage to the battery and connected equipment, and poses a fire hazard.
4.4 並列接続（オプション）
Multiple units can be connected in parallel to increase total energy storage capacity. Up to 15 units can be connected in parallel.
Figure 6: Visual representation of how multiple DATOUBOSS battery units can be connected in parallel to expand energy storage capacity.
When connecting battery packs in parallel, use the DIP addressing function. If DIP6 is connected to ON, use the default automatic address assignment. Otherwise, use the DIP switch on the BMS to set the address to distinguish different data packets.
