• Limited to the conversion conditions of the BDU internal DC, the maximum number of HV9637 modules in the Tower series of products is 6.
  

1. Unpacking
   
2. Separate the BDU and Base
   
3. Spacing
   
4. Stacking and locking
   Note: When assembling the BDU, ensure that the BDU circuit breaker is in "OFF" position.
   
5. Connecting the cables
   
   Note: We recommend that a circuit breaker is installed between the battery and the inverter to prevent the battery or the inverter being damaged when a short circuit occurs.
6. Earth connection
   
7. Switching the battery system on
   1. First, set the BDU circuit breaker to "ON" position.
   2. Set the ON/OFF switch to "ON", press and hold the "WAKE" button for 10s. Release the button and the green light will stay on; the battery has been turned on successfully.
      
8. Parallel connection
   
   Dyness supports a maximum of 4 clusters and a dedicated Combiner box (DCB-TW) must be configured.
   Single cluster installation is the same as stand-alone. For others, please consult Dyness.

11. Goodwe ET Inverter
    Dyness has a standard communication network cable. It is recommended to use the GW configuration network cable and directly connect to the CAN port of the battery BDU.
    Note: PV Master selects the TOWER PRO version, to ensure that the inverter is version 22 or later.
    
12. Solis RHI Series Hybrid Inverter
    Use the configuration standard network cable.
    

TOWER System Expansion

13. Module expansion
    It is necessary to ensure that the power of the added module is 100%, and the power of the expanded system is also 100%.
    (The dealer is required to provide SOC100% module. If you operate by yourself, please follow the following steps.)
    
    1. Add the module to be charged between BDU and Base.
       
    2. Charge it with DC power supply until BDU is cut off, indicating that SOC is 100%.
       

Note: If you do not have the respective equipment, please ask the dealer to charge the module
