1. Safety Precautions
1.1、Reminding
1）It is very important and necessary toread the user manual carefully (in the
accessories)before installing or using battery. Failure to do so or to follow any of the
instructions or warnings in this document can result in electrical shock, serious injury, or
death, or can damage battery,potentially rendering it inoperable.
2）It is strictly forbidden to immerse thebattery in water or rain.
3）Prohibit using and shelving the battery beside the high temperature source.
4）Please usethe module according to the charge and dischargeparameters specified
in this manual.
5）It is prohibited to connect thebattery and AC power directly.
6）Forbid discarding the battery into fire or heater.
7）Forbid breaking up the battery and its part.
8）Forbid to rap, stomp and throw thebattery.
9）Even if the grid is cut off, the batterymodule still has the voltageoutput,please
take care to avoid electric shock or shortcircuit when using battery module.
10）If the batteryis stored for long time, it is required to charge them every six
months, and the SOC shouldbe no less than 90%.Battery needs to be recharged within
12 hours,after fully discharged.
11）Do not expose cable outside.
12）All the battery terminals must be disconnected for maintenance.
13）Do not connect battery with PV solar wiring directly.
14）Please contactthe supplier within 48 hours if there is something abnormal.
15）In areas with poor environmental conditions,effective protective measures must
be taken for battery module, such as good grouding, sunshading board,rain cabinet and
dustscreen,to avoid lightning, rain, snow, high temperature, dust damage battery
module and impact battery life.
16）For being used in high temperature areas, the battery must be used in cabinets
with corresponding heat dissipation equipment (fans or air conditioners). In low
temperature areas, the battery must be used in cabinets with corresponding heating
equipment (heating plates or air conditioners). In coastalareas, the batterymust be used
in a cabinet with the corresponding salt spray protection capability.
17）Unless otherwise specified, the charging and discharging current for the battery
module and battery module is recommended to be set at 0.5C3.

5.3、Tools
The following tools are required to install thebattery pack.
Wire cutter Crimping Modular Plier
Screw Driver styleammeter
5.4、NOTE Use properly insulated tools to prevent accidental
electric shockor short circuits.
If insulated tools are not available, cover the entire
exposed metal surfaces of the available tools, except
their tips, with electrical tape.
5.5、Safety Gear

5.6、Installation
5.6.1、Package Items
Unpacking andcheck the Packing List.
1）For battery module package:
Two power cables and one communication cable for each battery
package:
2）Grounding cable:
Grounding cables use10AWG yellow-green cables.
150mm
150mm
300mm
1000mm

Module grounding is based on metal directly touch between the
module’s surface and rack’s surface. So it needn’t grounding cables at all. If
uses normal rack, it can remove the paint at the corresponding place.Or
install a grounding cable to the grounding point of the modules.
3）For battery system connects to inverter:
(Need to be purchased separately,orspecify separately when placing
an order)
4000mm
Actual length
Actual length

4）Two long power cables (current capacity 120A) and one
communication cable for each energy storage system.
5、Standard plug:
SC25-8 terminal
3、The length of the
wiring harness is
150mm, and the
terminals are quickly
plugged in at both
ends (maximum 120A)
4、Cable longitud:
Customize according
to actual order
(Two power cables
maximum 120A)
1、Communication line:
Inverter connected to
battery CAN。
2、Communication line:
Battery to battery RS485。

5）Adjust the ADD Switch as defined in thefigure belowe.
5.6.2、Installation Location
Make surethat theinstallation location meets thefollowing conditions:
1）The area is completely water proof. The floor is flat and level.
2）There are no flammable or explosive materials.
3）The ambient temperature is within the range from -5°C to 45°C.
The temperature and humidity is maintained at a constant level. There is
minimal dust and dirt in the area.
4）The distancefrom heat source is more than 2 meters.
5）The distancefrom air outlet of inverter is more than 0.5 meters.
Do not cover or wrap the batterycase or cabinet.
6）Do not place at a children or pet touchablearea. The installation
area shallavoid of direct sunlight.
7）There is no mandatory ventilation requirements for battery
module,but pleaseavoid of installation in confined area.The aeration shall
avoid of high salinity, humidity or temperature.
8）CAUTION：
If the ambient temperature is outside the operating range, the battery
pack stops operating to protect itself. The optimal temperature range for the
batterypack to operateis 25°C to 35°C. Frequent exposure to harsh
temperatures may deteriorate the performance and life of the batterypack.

6. Trouble Shooting Steps
6.1、Problem determination based on:
1）Whether the battery can be turned on or not;
2）If battery is turned on, check thered light is off, flashing or
lighting;
3）If the red light is off, check whether the batterycan be
charged/discharged ornot.
6.2、Preliminary determination steps:
1）Battery cannot turn on, switch on thelights are all no lighting or
flashing.
If the battery RESET switch is turned on, theRUN light is flashing,
and theexternal power supply voltage is 48V or more, thebattery still
unable to turn on, please contactdistributor.
2）The batterycan be turned on, butred light is lighting, and cannot
charge or discharge. If the red light is lighting, that means systemis
abnormal, please check values as following:
a）Temperature: Above 45℃or under -5℃, thebattery could not
work.
Solution: To move battery to the normal operating temperature range
between -5℃and 45℃.
b）Current: If current is greater than 100A, battery protection will
turn on.
Solution: Check whether current is too large or not, if it is, to change
the settings on power supply side.
c）High Voltage: If charging voltageabove 54V, battery protection
will turn on.
Solution: Check whether voltage is too high or not,if it is, to change
the settings on power supply side.
d）Low Voltage: When the battery discharges to 40.0V or less,
batteryprotection will turn on. Solution: Charge thebattery for some time,
the red light turn off.
Excluding the four points above, if the faulty is still cannot be
located, turn off power switch of the batteryand repair.
