Use properly insulated tools to prevent accidental electric shock or short circuits. If insulated tools are not available,cover the entire exposed metal surfaces of the available tools, except their tips, with electrical tape.
Safety Gear
It is recommended to wear the following safety gear when dealing with the battery back.

Installation

One set Lithium battery product connects to Inverter

Multiple sets of Lithium battery product connects to Inverter

Installation Location

• Make sure that the installation location meets the following conditions.
• The area is completely water proof.
• The floor is flat and level.
• There are no flammable or explosive materials.
• The ambient temperature is within the range from 0℃ to 50℃.
• The temperature and humidity is maintained at a constant level.
• There is minimal dust and dirt in the area.
• Use fitting screws to fix the box on the wall.

CAUTION

• If the ambient temperature is outside the operation range, the battery pack stops operation to protect itself. The optimal temperature range for the battery pack to operate is 0℃ to 50℃ .
• Frequent exposure to harsh temperature may deteriorate the performance and life of the battery pack .

Trouble Shooting Steps

Problem determination based on:

1. Whether the battery can be turned on or not.
2. If battery is turned on, check the LED light is off, flashing or lighting.
3. If the LED light is off, check whether the battery can be charge/discharge or not.

Preliminary determination steps:

1. Battery cannot turn on, switch on the lights are all no lighting or flashing.
   • If the battery external switch is on, the LED light is flashing, and the external power supply voltage is 48V or more, the battery still unable to turn on, please contact distributor.
2. The battery can be turned on, but red light is lighting, and cannot charge or discharge. If the red light is lighting, that means system is abnormal, please check values as following:
   • a) Temperature: Above 50℃ or under -10℃, the battery could not work.
   • Solution: to move battery to the normal operation temperature range between -10℃ and 50℃.
   • b) Current: If current is greater than 150A, battery protection will turn on .
   • Solution: Check whether current is too large or not, if it is, to change the setting on power supply side.
   • c) High Voltage: If charging voltage above 58.4Vdc(48V system), battery protection will turn on. Solution: Check whether voltage is too high or not, if it is, to change the setting on power supply side.
   • d) Low Voltage: When the battery discharges to 44.8Vdc(48V system) or less, battery protection will turn on.
   • Solution: Charge the battery for some time, the LED light turn off.

The battery cannot be charged or discharged

1. Cannot be charged:
   • Disconnect the power cables, measure voltage on power side, if the voltage is 51.2~54.0Vdc(48V system) ,restart the battery, connect the power cable and try again, if still not work, turn off battery and contact distributor.
2. Unable to discharge:
   • Disconnect the power cables and measure voltage on battery side, if it is under 44.5V, please charge the battery. If voltage is above 48V and still cannot discharge, turn off battery and contact distributor.

Emergency Situations

1. Leaking Battery
   • If the battery pack leaks electrolyte, avoid contact with the leaking liquid or gas.If one is exposed to the leaked substance, immediately perform the actions described below . Inhalation: Evacuate the contaminated area, and seek medical attention.
   • Contact with eyes: Rinse eyes with flowing water for 15 minutes, and seek medical attention. Contact with skin: Wash the affected area thoroughly with soap and water, and seek medical attention.
   • Ingestion: Induce vomiting, and seek medical attention.
2. Fire
   • NO WATER! Only dry powder fire extinguisher can be used; if possible, move the battery pack to a safe area before it catches fire.
3. Wet battery
   • If the battery pack is wet or submerged in water, do not let people access it,and then contact an authorized dealer for technical support.
4. Damaged Battery
   • Damaged battery are dangerous and must be handled with the utmost care. They are not fit for use and may pose a danger to people or property. If the battery pack seems to be damaged pack it in its original container, and then return it to an authorized dealer.
