Why is the Pylontech PowerCube-X1 BMS status LED not working when battery modules are green?
If the Pylontech Storage BMS status LED is not working, but all battery modules’ status LEDs are green, it suggests that the control board has failed. You should change the control module (BMS module).
What to do if Pylontech Battery Pack's BMS Status LED is red while some battery modules are green and some are red?
If the BMS Status LED is red and some battery module LEDs are green while others are red, it means the battery string is under protection. This could be due to over current, over voltage, low voltage, over temperature, low temperature, or failure protection. Use monitoring software to check the battery cell and module for protection and failures.
Why can't I open the power relay on my Pylontech Battery Pack?
If the output relay of your Pylontech Battery Pack can’t be opened after opening the Power Relay Switch, it could be due to a failure in the main control board. In this case, consider changing the control module (BMS module). Also, check if the wire of the output relay or the power relay switch in the BMS is broken or loose, and fix it. If the wire is not the issue, consider replacing the control module.
What to do if the output relay won't actuate on my Pylontech Battery Pack?
If the output relay can't actuate on your Pylontech Battery Pack even when the Status LED shows normal, check if the wire of the output relay or the power relay switch in the BMS is broken or loose. Fix it, or change the control module (BMS module). Also, ensure the Power Relay Switch is closed.
How to fix Pylontech Battery Pack when I cannot close the power switch?
If you cannot close the power switch on your Pylontech Battery Pack, check if the DC output breaker is faulty. If it is, change the control module (BMS module).
Why can't I close the power switch on my Pylontech Storage?
If you cannot close the power switch, the DC output breaker may be faulty. Check the DC output breaker. If it is faulty, change the control module (BMS module).
What causes the Pylontech PowerCube-X1 Storage output relay to not actuate when the BMS status LED is normal?
If the Pylontech Storage output relay can't actuate even when the BMS status LED is normal, it could be due to a broken wire in the output relay or power relay switch within the BMS, or the power relay switch is open. Check the wires for looseness or breaks and fix them. You might need to change the control module (BMS module). Also, ensure the power relay switch is closed.
What should I do if the Pylontech PowerCube-X1 BMMS status LED isn't working, but all battery module LEDs are green?
If the Pylontech Storage BMMS status LED is not working but all battery module LEDs are green, the control board may have failed. Change the control module (BMMS module).
Why does my Pylontech Battery Pack show a temperature of -40?
If the battery module displays a temperature of -40 on your Pylontech Battery Pack, it is likely due to a failure in the temperature sampling wires. Check the wires of the temperature sampling module.
What does it mean if some battery module LEDs are red or off on my Pylontech Battery Pack?
If one or more of the battery module’s Status LEDs are red or not lighting up on your Pylontech Battery Pack after turning on the BMS, it indicates that the specific battery module has failed. In this case, replace the faulty battery module. Also, check the communication cable and address distribution.
