    3. Before connecting of 10kWh 48V Solar Battery Storage

    • After unpacking, please check the battery and packing list first, if the battery is damaged or spare parts are missing, please contact us.
    • Before installation, be sure to cut off the grid power and make sure the battery is in the turned-off mode;
    • Wiring must be correct, do not mix-connect the positive and negative cables, and ensure no short circuit with the external device;
    • It is prohibited to connect the battery with AC power directly;
    • The embedded BMS in the battery is designed for 48VDC, please DO NOT connect battery in series;
    • It is prohibited to connect the battery with different type of battery;
    • Please ensure the electrical parameters of battery system are compatible to inverter;
    • Keep the battery away from fire or water.


    4. Parallel use of 48V Solar Battery Storage
    When the battery needs to be used in parallel, the maximum connection is 10units, but we recommend to use 2-4 units according to application. The application needs power and communication connections as below, choose suitable accessories.

    5. Tesla Solar Battery Storage Replacement connection
    Let’s take 2 batteries for example, use an additional junction box (not included in the standard pack) to combine the power flow of both batteries:

    1. First refer to chart below to define master level and slave level battery
    2. Connect master battery’s positive pole to J1 and negative pole to J3 of the junction box
    3. Connect slave battery’s positive pole to J2and negative pole to J4
    4. Connect J5 with inverter’s positive pole
    5. Connect J6 with inverter’s negative pole
    6. Add suitable isolators when necessary


    6. Communication connection of 10kWh wall type lithium battery
    There needs to be cascade communication with master level and slave level settings. The master level and slave level has different address.


    7. Power Wall Delivery
