What to do if my Teze TW-EOR48 Battery Pack is not connected?
If your Teze Battery Pack is not connected, check if the battery is reliably connected. Also, verify that the battery's circuit breaker is not closed and ensure that the BMS of the Li-ion battery can communicate properly. The cause might be that the battery is not connected or the BMS is in discharge protection.
How to fix the Teze Battery Pack when the screen shows no display?
If the screen of your Teze Battery Pack isn't displaying anything, it could be due to no power input or the device being in sleep mode. Try closing the circuit breaker and ensuring the rocker switch is turned ON. If it's in sleep mode, push any button on the panel to exit sleep mode.
Why is my Teze TW-EOR48 showing an under-voltage error?
If your Teze Battery Pack displays an under-voltage error, it means the battery voltage is lower than the value set in parameter [14]. To resolve this, charge the battery and wait until the battery voltage is higher than the value set in the parameter item [14].
