Introduction

• 24/48VDC series Lithium battery power bank is one of the new energy storage products developed ,it can be used to support reliable power for various types of equipment and systems . Is especially suitable for application scenes of high power, limited installation space, restricted load-bearing and long cycle life.
• 24/48VDC series has a built-in BMS battery management system, which can manage and monitor cell information including voltage, current, and temperature. What’s more, BMS can balance cells charging and discharging to extend cycle life.
• Multiple batteries can be connected in parallel to expand capacity and power in parallel for larger capacity and longer power-supporting duration requirements.
• The capacity of the Lithium battery should be higher than the Solar Inverter which you will connect with.

Features:

• The whole module is non-toxic,non-polluting, and environmentally friendly.
• The cathode material is made from LiFePO4 with safety performance and long cycle life.
• Battery management system (BMS) has protection functions including over-discharge, overcharge,over-current, and high/low temperature.
• The system can automatically manage the charge and discharge state and balance the current and voltage of each cell.
• In the flexible configuration, multiple battery modules can be in parallel for expanding capacity and Power.
• Adopted self-cooling mode rapidly reduced system entire noise. The module has less self-discharge,up to 6 months without charging it on the shelf,no memory effect, and excellent performance of shallow charge and discharge.
• Working temperature range is from -10℃ to 50℃,(charge 0℃~ 50℃, discharge -10℃~ 50℃) with excellent discharge performance and cycle life.

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:

3. 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℃.

4. 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.

5. High Voltage: If charging voltage above 29.2Vdc(24V system) or 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.

6. Low Voltage: When the battery discharges to 22.4Vdc(24V system) 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 25.6~27.0Vdc(24V system) or 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 22.3 V or 44.5V, please charge the battery. If voltage is above 24V or 48V and still cannot discharge, turn off battery and contact distributor.
