Please follow below steps to implement battery connection:
- Assemble battery ring terminal based on recommended battery cable and terminal size.
- Connect all battery packs as units requires. It’s suggested to connect at least 2 sets of LPBF48V for inverter larger than 7.5KVA in parallel connection.
Note: if you need the battery wake-up when the grid back, connect the battery with grid use power adapter and communication line 1 shown in the package list.
3.3 Connection for Parallel Mode
The eStrong LPBF series battery support to be connected in parallel for expansion. If you need one more battery bank work in parallel mode, connect the battery as shown in PIC 2
Step 1 : The batteries are placed as shown in Figure 1
Step 2: The schematic diagram of the parallel connection of two battery packs is shown in Figure 2.
Step 3: The schematic diagram of the parallel connection of six battery packs is shown in Figure 3.
Note: After completing the above 4 steps, arbitrarily select the positive and negative poles of one of the battery packs to output (the upper battery pack or the lower battery pack. you can not select the positive and negative poles of the two battery packs at the same time). After confirming the correct connection of the inverter, controller and battery, you can turn on any of the switches and use the battery group happily
Note: One group of LPBF48V can be stacked up to 2 layers, and up to 6 in parallel connection.
For pure off grid system ,the PV awake wire need to be connected with MPPT charge controller if the battery pack is charged by solar panels only. The connection diagram as below:
