Manual Instruction
The Energy Storage Batteries System provides the energy storage for PV users and backup
power support for the important electrical equipment. The battery system can store excessive
power generated by PV system at daytime, and can utilize the stored energy (if necessary) to
supply power for electrical equipment at night, thus improving the utilization efficiency of
photovoltaic power generation, shaving peaks and filling valleys, providing backup power for
emergency and important electrical equipment to avoid data and financial loss caused by sudden
power outage.
The user manual introduces battery details like the basic structure, parameters, procedures
and methods of installation, operation and maintenance.
This manual is only for the 51.2V 100Ah Wall Mounted Lithium Battery, but the inverter
and any other equipment is not included.
This PRODUCT can be installed in parallel mode, more attention should be paid for the DIP
and address selection.

7. Operation
7.1 Charging precautions
1) Charging current
The charging current must not exceed the maximum allowable charging current specified
in this specification. Charging with abnormal current will cause the system protection to start,
which may affect normal use.
2) Charging voltage
The charging voltage shall not exceed the maximum charging voltage specified in this
specification. When the battery voltage is higher than the maximum charging voltage, it will
cause the system protect ion to start, which may affect the normal use.
3) Charging temperature
The battery must be charged in the range of 0°C to 55°C.
4) Reverse charging is prohibited
The battery must be connected according to the installation instructions. Reverse charging
is prohibited and short circuit is prohibited in the positive and negative electrodes of the battery
to avoid the battery pack failure and damage.
7.2 Discharging precautions
1) Discharge current
The load and discharge current of the battery pack should be controlled reasonably.
Excessive use will cause irreversible damage to the battery and affect the normal use.
2) Discharge voltage
Overdischarging of the battery pack will cause adverse internal chemical reactions, so as
to affect the normal use, should try to avoid this situation. After the occurrence of
overdischarge, the battery should be evaluated before continuing to use.
3) Discharge temperature

Amensolar Lithium Battery AW5120 User Manual
17
The product must be discharged in the range of 20℃~55℃, abnormal discharge
temperature may affect the life of the product or make the system protection start, affecting the
normal operation.
7.3 Others
In order to prevent leakage, heating and explosion of the battery, the following operations
should be avoided:
1) Do not put the battery into the fire or heat it;
2) Do not break down or disassemble the battery;
3) It is strictly prohibited to immerse the battery in seawater or water. When not in use, it
should be placed in a cool and dry environment;
4) Do not place the battery near high temperature sources, such as fire, heater, etc.;
5) It is strictly prohibited to connect AC directly, and the DC charger must be used to
charge in accordance with the regulations;
6) It is strictly prohibited to use the battery by reversing the positive and negative
electrodes;
7) Do not use metal to directly short circuit the positive and negative electrodes of the
battery;
8) It is forbidden to store the battery together with metal, and insulation protection
measures should be taken;
9) It is forbidden to use or place the battery at high temperature, otherwise it may cause
overheating, function failure or life reduction of the battery;
10) Do not use the battery in places with strong static electricity and magnetic field,
