Trouble Shooting Steps

Problem determination based on:

1. Whether the battery can turn on or not;
2.  If battery is turned on, check the red light is off, flashing or lighting;
3. If the red light is off, check whether the battery can 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 RUN light is flashing, and the external power supply voltage is 48V or more, the battery still unable to turn on, please contact Pylontech.

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 operating temperature range between -10℃ and 50℃

   • 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 voltage above 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 44.5V or less, battery protection will turn on.
     Solution: Charge the battery for some time, the red light turn off Excluding the four points above, if the faulty is still cannot be located, turn off battery and repair.

The battery cannot be charged or discharged

1. Cannot be charged:
   Disconnect the power cables, measure voltage on power side, if the voltage is 53~54V, restart the battery, connect the power cable and try again, if still not work, turn off battery and contact Pylontech.

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 Pylontech.

Emergency Situations

1. Leaking Batteries
   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 Batteries
   If the battery pack is wet or submerged in water, do not let people access it, and then contact Pylontech or an authorized dealer for technical support.
