LiFePO4 Battery System for Households
Special Attention: It is strongly recommended to stop using the load when the battery pack
is over-discharged. The battery pack should not be repeatedly force activated for discharge
or you may damage the battery cells reducing their life span. If the battery pack is low and
the internal BMS failsafe has activated you must charge the battery immediately. If you do
not you may need to use the AC or PV activation method to wake the battery. Doing so will
reduce the lifespan of your pack

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.
3.1 Unpacking and Inspection
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 mounted 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.

Grid activation communication wire
( used with 6)
Used for activating the pack when grid
power recover
Please follow below steps to implement battery connection:
Assemble battery ring terminal based on recommended battery cable and terminal size.
1. It’s suggested to connect at least 2 sets of batteries to ensure maximum pack life, especially for higher
wattage inverters.
Note: if you need the battery to wake-up when grid power returns, connect the battery with a grid use
power adapter and communication line 1 shown in the package list.
The battery supports parallel connection for capacity expansion. Connect parallel batteries as shown in PIC 2
3.3 Connection for Parallel Mode
Step 1: The batteries are
placed as shown in Figure
Step 2: Battery terminal connection As shown in
Figure 2, the connection line between the two
batteries is connected through the hole.
Step 3: The communication terminal (the other
end) is connected as shown in Figure 3. Only
one communication line (network cable) is
required to connect through the hole between
the two batteries. Another one is used as a backup.
Step 4: After all connections have been made, as
shown in Figure 4, secure the gap between the two
batteries with the accessories and secure the battery
pack against the wall.
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 the battery bank is ready for use.

Remark①: 1 in SW1-SW5 indicates ON status, and 0 indicates OFF status.
Remark②: When multiple battery packs communicate, the last battery pack SW5 needs to be in the ON
status, otherwise the communication may have interference.
Remark③: 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
Remark④: 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
Remark⑤: 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
