2. Product Introduction
AMENSOLAR A5120, a 2U rack-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;
2U rack structure, it can be directly loaded into a 600*800mm standard network cabinet. It is
easy to be installed with the characteristics of easy maintenance, flexibility and versatility.
It is equipped with stacking pack accessories, which can be stacked without cabinets.
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.
BMS uses professional battery management chip, ARM low power processor, more energy
saving.

2) If the battery is stored for a long time, it needs to be charged once every six months, and the
SOC should not be less than 80%;
3) After the battery is fully discharged, it should be charged within 12 hours;
4) Do not expose the cable to the outside;
5) All battery terminals must be disconnected for maintenance;
6) If any abnormal, please contact the supplier within 24 hours.
7) The direct or indirect losses caused by the above items shall not be covered by the warranty.
8. Abnormal Conditions and Fault Handling
8.1 Troubleshooting steps
8.1.1 Check whether the battery can be turned on;
8.1.2 If the battery is on, check whether the red light is off, flashing or on;
8.1.3 If the red light is off, check if the battery can be charged / discharged.
8.2 Failure recognition
8.2.1 The battery cannot be turned on, and the lights are not on or flashing after the boot.
If the external power of the battery is on, the state light is flashing, the external power supply
voltage is above 48V, and the battery still cannot be turned on, please contact the supplier.
8.2.2 The battery can be turned on, but the red light is on and cannot be charged or discharged.
The red light is on, which means the system is not normal, check the following values:
Temperature: over 56℃ or below-20℃, the battery does not work.
Solution: Move the battery to the normal operating temperature range of-10℃ to 50℃.
Current: If the current is greater than 100A, the battery protection is turned on.
Solution: check whether the current is too large, if it is too large, to change the setting of the
power side.
High voltage: If the charging voltage exceeds 57.6V, the battery protection will be turned on.

Amensolar Lithium Battery A5120 User Manual
14
Solution: Check whether the voltage is too high, and if so, change the setting of the power supply
side.
Low voltage: When the battery discharges to 44.8V or lower, the battery protection is turned on.
Solution: Charge the battery for a while, and the red light will go out.
Excluding the above four points, if the fault still cannot be found, please turn off the battery and
repair it.
8.3 Charging troubleshooting
8.3.1 Unable to charge:
Disconnect the power cable and measure the voltage on the power side. If the voltage is 53~54V,
restart the battery, connect the power cable and try again. If still not, turn off the battery and contact
the dealer.
8.3.2 Failure to discharge:
Disconnect the power cable and measure the voltage on the battery side. If the voltage is lower than
48V, please charge the battery. If the voltage is above 48V, and still cannot discharge, please turn off
the battery and contact the dealer.
9. Emergency
9.1 Battery leakage
If the battery has leaked the electrolyte, avoid contact with the leaked liquid or gas. If exposed with
this substances, the following measures should be taken immediately:

Eye contact: rinse the eyes with running water for 15 minutes and seek medical care.
Contact with the skin: wash the affected area thoroughly with soap and water, and seek medical
treatment.
Intake: induced vomiting and seek medical assistance.
9.2 Fire
Don't use water! Only dry powder extinguishers; if possible, move the battery pack to a safe area
before catching fire.
9.3 Water
If the battery pack is wet or soaked in water, do not contact it, and then contact the manufacturer or
authorized dealer for technical support.
9.4 Battery damage
Damaged batteries are dangerous and must be dealt with in the most prudent manner. They are not
