01
LiFePO4 Battery System for Households
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.
1. The batteries can be connected in parallel. Series connection is not allowed.
2. The batteries are not allowed to connected with PWM controller for charging.
1.4 Can be connected in parallel

LiFePO4 Battery System for Households
2. INTRODUCTION
The battery system main using Solar power system for Family house.It also have a with to controller the
battery easily and protect our Household application timely.
• Iron phosphate-lithium power battery
• Long warranty period:5 years
• Higher energy density,smaller volumn for household.
• Support connected in parallel mode for expansion
• Photovoltaic system: This battery pack is designed for household photovoltaic systems.
• Battery management system (BMS): The battery packs built-in BMS monitors its
operation and prevents the battery from operating outside design limitations.
• Expandability: This battery pack can be easily expanded by adding expansion battery packs
in parallel connection.

The LPBA 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
3.3 Connection for Parallel Mode
Step 3: The schematic diagram of the parallel connection of six battery packs is shown in Figure 3.
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.

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.

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 :

LiFePO4 Battery System for Households
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.
Step 4: The communication terminal (the other end) is connected as shown in Figure 4. Only one communication line
(network cable) is required to connect through the hole between the two batteries. Another one is used as a backup.
Note: One group of LPBA48V can be stacked up to 6 layers, and up to 12 in parallel connection.
