charge & discharge current, max. output power, recommend output
power, DOD, modules connection, communication, ingress protection,
cycle life, working temperature range, net weight, gross weight,
product dimension, and package dimension as specified in the
specifications.
Product Usage Instructions:
- Before using the LiFePO4 Battery System, read all instructions
and cautionary markings on the unit, batteries, and the user
manual. - Do not disassemble the battery. If service or repair is
required, take it to a qualified service center to avoid any
risks. - To reduce the risk of electric shock, disconnect all wirings
before performing any maintenance or cleaning. Turning off the unit
does not eliminate the risk. - Avoid sparks or short circuits that could cause an explosion or
fire. - Strictly follow the installation procedure provided in the user
manual. - For inverter larger than 6KVA, at least 2 sets of LPBF48V
batteries should be connected in parallel to support full output
load. - The system should be connected to a permanent grounded wiring
system following local requirements. - Never cause AC output and DC input short-circuited. Do not
connect to the mains when DC input is present. - The batteries can be connected in parallel but not in series.
Use them in an upright position only. - Do not connect the batteries with PWM controller for
charging.

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 LPBF48V 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 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 .
Main Circuit
LiFePO4 Battery System for Households
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 :

Remark: 1 in SW1 -SW5 indicates ON status, and 0 indicates OFF status.
Remark: When multiple battery packs communicate, the last battery pack SW5 needs to be in the ON
status, otherwise the communication may have interference.
Remark: 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
Remark: When the battery pack ID is set to 1 -1 5, it means that the parallel operation is required, and it is necessary to detect whether the parallel condition is satisfied
Remark: 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
