5. Power wall 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.
