14. 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.

1.4 Can be connected in parallel

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.
3. The batteries are allowed to connected with MPPT controller for charging, but the maximum PV voltage in the system must be less than 100Vdc.
   Special 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.

2.4 Recommended Settings
Lithium battery pack is not same as lead-acid battery, so for the devices which you connect with the battery pack for charging or discharging, such as inverters, MPPT charger controllers or UPS, please implement pre-settings as recommended settings as below before you launched them.

Notes: “N” means the number of battery packs connected in parallel.

Installation Procedure

3.1 Setup Script
Step 1: Remove the wooden board from the outer box, leaving only the bottom pallet and product

Step 2: Remove the fastening screws on the pallet fixture

Step 3: Take out the fixed parts of the pallet, align them with the U-shaped holes at both ends of the pallet, and clamp them onto the pallet to form unloading steps.Finally, use the M6X12 screw to lock the fixed parts to the baseplate.

Step 4: Push the product down the pallet along the steps and move it to the installation position

3. INSTALLATION
3.1 Unpacking and Inspection
Before installation, please inspect the unit. Be sure that nothing inside the package is damaged. You should have received the following items inside of package.

3.2 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 for inverter larger than 10KVA 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 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 1.

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 :

OPERATION

Once the batteries are connected well, close the breaker to the ON block, press On/Off button to enable the output of the battery pack.

4.1 Switch On / Off

1. Switch on: press On/Off button to switch on the battery, then the battery will do self-inspection before enable output. The LCD will show the SOC.

Remark ①: 1 in SW1-SW5 indicates ON status, and 0 indicates OFF status.
Remark ②: When multiple battery packs communicate, the last battery pack SW5 needs to be in the ON status, otherwise the communication may have interference.
Remark ③: When the battery pack ID is set to 0, it means stand-alone operation, and it is not necessary to detect whether the parallel condition is satisfied ⑤
Remark ④: When the battery pack ID is set to 1-15, it means that the parallel operation is required, and it is necessary to detect whether the parallel condition is satisfied ⑤
Remark ⑤: The parallel condition is that the difference between the battery voltage of the local battery and all the battery pack voltages is <3V, otherwise wait until the condition is satisfied
