NOTICE

  1. The optimum operating temperature range is from 59℉ to 86℉(15°C to 30°C), Frequent exposure to the harsh temperatures may worsen the performance of the battery pack and cycle life.
  2. The current of the heating film is calculated in addition and is not added to the current detected by the BMS.
  3. If the battery system is fully charged for the first time, the heating is stopped after a delay of 1 hour.
  4. The heater operates within a temperature range of -13°F to 41°F (-25°C to 5°C).

Condition 1: When the battery temperature falls between 14°F to 41°F (-10°C to 5°C), the heater activates, initiating a low-current charging process. The heater will be off at 53.6°F (12°C), but regular charging of the battery continues.
Condition 2: In cases where the battery temperature is below 14°F (<-10°C), the charging current is exclusively directed to the heating system until the battery temperature rises above 14°F (-10°C). Once this threshold is reached, the heater operates as described in Condition 1.
Please note that the heating system operation does not impact the State of Charge
(SOC) of the battery.

Troubleshooting and FAQ

Items Solution Measure


Unable to start

|

  1. Power on battery and press RESET 6s to observe whether the battery can be started.
  2. Charge the battery use a charger or inverter to provide 54~57.6V voltage and observe it can be started.

|




Unable to charge

|

  1. Check whether the cable connection between the battery and the inverter/charger is correct.
  2. Check whether the inverter/charger setting is correct.
  3. Check whether the battery is in charge protection mode, if yes, try to discharge the battery.

|


Unable to discharge

|

  1. Check whether the cable connection between the battery and the inverter/charger is correct
  2. Check whether the battery occurs short circuit, reverse connection, pre-charge failure during connection inverter etc.
  3. Check whether the battery is in discharge protection mode, if yes, try to charge the battery.

| **** If the abnormal status still alive after above steps, please contact your supplier.

If there is any other situation(s) excluding in this table, turn off the fault battery, contact your supplier.


High/Low temperature

|

  1. Stop the battery system for a while, check whether the installation location temperature meet the requirement.
  2. Avoid continuous full charging and discharging.

High current| Check the configuration and parameters setting on the inverter/charger is correct.
ALM always on|

  1. Check the fault information on the inverter APP or display if possible.
  2. Ask your supplier to offer BMS monitoring software to locate the reason and back to them for solution.

|
**** Communication fail|

  1. Check the communication cable type is correct and is contacted well.
  2. Check the DIP switch setting is correct.
  3. Check the inverter protocol related setting is correct.
  4. Check both battery and inverter are working properly.

|

  • Q1: Battery maximum SOC is 99% and never goes to 100%SOC during daily  cycle use, why?
    Generally, there is no effect to system on this point. BMS will calibrate the SOC to 100% when reached cut-off current or trigger CHVP, however, to avoid battery from being overcharged and to extend the cycle life as longer as possible, we left a room and set a charging profile to let battery not be charged at high voltage near full. Keep float the battery for approximately 0.5~1 hour to calibrate.

  • Q2: ‘High voltage’ and ‘cell unbalance’ warning and alarm in rare cases, does it mean battery is damaged?
    No. This is not unusual and happened on new batteries that are not balanced yet, please lower the maximum charge voltage (54.6V) and float the battery via grid or generator. If not solved, please contact your supplier.

  • Q3: When having multiple batteries in parallel connection, the battery on the end can’t be fully charged.
    Pay attention to your wiring diagram, please always follow the manual wiring advises and choose proper cable size and pair.

  • Q4: The current is 0A when connecting with a very small load at the situation that having multiple batteries in parallel connection, how to solve it?
    Each BMS has a threshold current of 0.5A (~25W) before it begins to report, this leads the inaccurate display of the current.

  • Q5: SOC suddenly jump to 100% during charging.
    This is normal in off-grid application and usually happened on batteries that not been calibrated SOC for long time, we suggest to fully charge the batteries per month.

Transport, Storage

  • Do not violently shake, impact or squeeze, and prevent sun and rain during the transportation.
  • Do light take and put and strictly prevent falling, rolling, and heavy pressure during loading and unloading.
  • The battery should be placed in a dry, clean, dark, and well-ventilated indoor environment for long- term storage, and the recommended storage temperature range is 15~30℃.
  • No harmful gases, flammable and explosive products and corrosive chemical substances in the storage location.
  • The batteries should be stored and transported in close to 50% SOC, do not store over 80%SOC for long time.
  • If do not use for a long time, the battery needs to be charged every 6 months.
  • No fall down, no pile up over 6 layers, and keep face up.

Disposal of battery
Disposal of battery must comply with the local applicable disposal regulations for electronic waste and used batteries, please review your local Battery recycling or management regulations or contact your supplier for more information.
