2. Product Introduction
AMENSOLAR AW5120, a 2U wall-mounted battery module, is one of the new energy
storage products that can be used to support reliable power for a variety of equipment and systems.
The product is especially suitable for the application scenarios of high power, limited installation
space, limited bearing capacity and long cycle life. The battery module has a built-in BMS battery
management system that can manage and monitor battery information, including voltage, current,
and temperature. In addition, BMS can also balance the charge and discharge of the battery to
extend the cycle life. Multiple batteries can be connected in parallel to expand capacity and power
in parallel to achieve the requirements of greater capacity and longer power support time.
2.1 Product features
Lithium iron phosphate battery, the weight is reduced by 40% compared with the same
specifications of lead-acid battery;
Wall-hanging structure, the pack can be mounted on the wall with the characteristics of easy
maintenance, flexibility and versatility;
Battery pack shell with insulation coating metal sheet metal;
The power output and input terminal of the battery pack adopts a high-power quick-plug
connector, which supports hot swap.
The battery pack can be used in parallel with a maximum of 16 pieces and cannot be used in
series.
Low self-discharge, no memory effect, shallow charge and shallow discharge performance is
better;

When the BMS is in sleep status, press the button (3~6s) then release, the BMS will be activated,
and the LED indicator will be continuously lit from "RUN" for 0.5 seconds.
When the BMS is active, press the button (3~6s) then release, the BMS will sleep and the LED
indicator will light from the lowest battery power light for 0.5 seconds.
When the BMS is active, press the button (6~10s) and release, BMS will reset, and all the LED
lights are on at the same time for 1.5 seconds.
Dip Switch Address
When multiple battery modules are connected in parallel, each battery module will have a
different address code, up to 15 addresses.
Note: In the following table, address 1 is the master, and the other addresses are the slave.
