Packing List

Overall Structure

The Jinko Battery System JKS-BXXX37-CS is composed of a Base unit and optional Battery Management Units (BDU) and Battery Modules (JKS-Bxxx37-CS). The system can be expanded by connecting multiple battery modules.

• Limited to the voltage interval of the inverter, the smallest number of JKS-B9637-CS modules used by series is 2.
• Limited to the conversion conditions of the BDU internal DC, the maximum number of JKS-B9637-CS modules is 6.

Module Capacities:

• JKS-B19237-CS: 7.1kWh
• JKS-B28837-CS: 10.6kWh
• JKS-B38437-CS: 14.6kWh
• JKS-B48037-CS: 17.7kWh
• JKS-B57637-CS: 21.3kWh

The system includes a Base unit, a BDU, and multiple JKS-Bxxx37-CS battery modules stacked on top.

Installation Steps

1. Unpack: Unpack the BDU+Base and HV9637 battery modules.
2. Separate the BDU and Base: Carefully separate the BDU from the Base unit using appropriate tools.
3. Balance: Ensure proper ventilation by allowing a clearance of approximately 300mm to the side and approximately 50mm to the wall. This helps dissipate the heat of the battery.
4. Stacking and locking: When assembling the BDU, ensure that the circuit breaker switch of the BDU is in the "OFF" state. Stack the modules securely and tighten the fixed bolt in turn.
5. Connect the cable: Connect the communication cable, negative cable, and positive cable between the battery modules and the BDU. It is recommended that a circuit breaker is installed between the battery and the inverter to prevent damage when a short circuit occurs.
6. Earth connection: Connect the earth cable to the designated grounding point, ensuring a secure connection. The diagram shows a green/yellow wire being connected.

Battery System Operation

1. Battery system on:
   1. First, push the circuit breaker of BDU to the "ON" state.
   2. Turn the self-locking switch to "ON", press and hold the "WAKE" button for 3 to 7 seconds. Release your fingers; the green light will always be on, and the battery will be turned on successfully.
2. Battery system Shut down:
   1. Switch off the "POWER ON" switch.
   2. Switch the "DC BREAKER" to the "OFF" state.

Battery System Expansion

Solution 1: High Voltage battery expansion (With DC Charger)

1. Initial Preparation: Disconnect existing battery and ensure safety precautions.
2. Charge the original battery tower to SOC 100%: Use an inverter to charge the tower until the SOC reaches 100%.
3. Charge the new battery module to 100% with a DC charger: Add the new module JKS-B9637-CS between the base and HVB (High Voltage Box). The factory SOC of the module is initially set at 50%. A DC charger is needed. Configure the charging voltage of the DC charger to 110V. Continue charging the battery until the HVB automatically terminates the charging process. The diagram shows a new battery module being connected to an existing stack, with a DC charger supplying power.
4. Add the new battery module to the system: The diagram shows a new battery module, charged to 100% SOC, being added to an existing battery stack.

Solution 2: High Voltage battery expansion (Without DC Charger)

1. Initial Preparation: Disconnect existing battery and ensure safety precautions.
2. Preparing for Expansion: Discharge the original battery tower to 40% State of Charge (SOC).
3. Integrating the New Battery Module:
   1. Add the new battery modules into the existing battery tower.
   2. In cases of insufficient photovoltaic (PV) power generation, enable grid charging to the batteries in the inverter setting. Continue charging until the battery state of charge (SOC) reaches 100% or the charge current limit reaches 0A. The diagram shows modules being added to a stack, with SOC levels indicated.
4. Removing the new battery modules and keep charge the original batteries to SOC 100%:
   1. Carefully disconnect and remove the new battery module from the integrated system.
   2. Restart the charging process for the original battery tower until battery state of charge (SOC) reaches 100% or until the charge current limit reaches 0A. The diagram shows modules being removed and the remaining stack being charged.
5. Reintroducing the New Battery Module:
   1. Reconnect the new battery module, which is already at 100% SOC, to the original battery system.
   2. Ensure that the new module is securely integrated into the original system. Furthermore, please remember to restore the original settings of the inverter. The diagram shows a 100% SOC module being reconnected to the stack.
6. Finalizing:
   1. Perform system assessment for stability and functionality.
   2. Create documentation for future reference.

Safety Warning: Ensure safety gear and protocols during all connections and disconnections to prevent accidents or damage. Always prioritize safety during installation.

Please refer to the detailed manual for specific instructions, manufacturer recommendations, and safety guidelines.
