3.2 Mounting the Unit

Consider the following points before selecting where to install:

• Do not mount the battery on ﬂammable construction materials.

• The ambient temperature should be between 0°C and 45°C to ensure optimal operation.

• The recommended installation position is to be adhered to the wall vertically.

• Be sure to keep other objects and surfaces as shown in the right diagram to guarantee sufﬁcient heat dissipation and

to have enough space for removing wires.

Please follow below steps to implement battery connection:

1.Assemble battery ring terminal based on recommended battery cable and terminal size.

2.Connect all battery packs as units requires. It's suggested to connect at least 2 sets of WG48350 for

inverter larger than 6KVA 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 WG48350 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 1.

PICTURE

Main Circuit

Step 1: The schematic diagram of the parallel connection of three battery packs is shown in Figure 1.

Note:After completing the above steps, arbitrarily select the positive and negative poles of one of the battery packs to output.

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.

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 :
