Do not install the battery in any environment of temperature below 0°C or over 55°C,and humidity over 80%.15. Do not put any heavy objects on the battery.1 ABOUT THIS MANUALSpecial Attention: Due to the built-in protection board of the lithium battery pack is with over-discharge protection function, it is strongly recommended to stop using the load when the battery pack is over-discharged. The battery pack cannot be repeatedly activated for discharge. Or the battery may be failed to be activated by the AC or PV activation cable ( It requires a special charging activation method), so cannot be charged. Therefore, when the battery pack is low power, please charge the battery as soon as possible when main power or solar energy is available.1. The batteries can be connected in parallel. Series connection is not allowed. Use in upright position only.2. The batteries are not allowed to connected with PWM controller for charging.1.4 Can be connected in parallel

LiFePO4 Battery System for HouseholdsLiFePO4 Battery System for Households0605Before installation, please inspect the unit. Be sure that nothing inside the package is damaged. You should have received the following items inside of package.3.1 Unpacking and Inspection3. INSTALLATION3.2 Mounting the UnitConsider 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.The WG48350 series battery support to be connected in parallel for expansion.

Main Circuit
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.
Step 1: The schematic diagram of the parallel connection of three battery packs is shown in Figure 1.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 :7
