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:
- First refer to chart below to define master level and slave level battery
- J3 Connect master battery's positive pole to J1 and negative pole to J3 of the junction box.
- Connect slave battery's positive pole to J2 and negative pole to J4.
- Connect J5 with inverter's positive pole.
- Connect J6 with inverter's negative pole.
- Add suitable isolators when necessary.
