Bluetti AC50S power stations can really come in handy when you need emergency backup power. However, they are not without their issues. When you run into an error code, it will help to have the answers you need to get it back up and running. This is where this post can help.
Here are the most common error codes associated with the Bluetti AC50S 500Wh power station:
Error E01
Cause:
The heat sink’s over-temperature protection kicks in when temp reaches ≥ 75℃.
E01 Solution:
Turn off the machine, or idle it until the temp reaches ≤ 70℃. Auto recovery should then start.
Error E02
Cause:
The machine begins its low-temperature protection when it reaches < -8℃.
E02 Solution:
The machine will self-recover while operating when temp reaches ＞-2℃, or it must be turned off and warmed up.
Error E04
Cause:
The power station battery temperature rises to > 68℃.
E04 Solution:
The machine will self-recover when temp reaches < 58℃.
Error E05
Cause:
The machine’s battery temperature drops to < -8℃.
E05 Solution:
The machine’s temp must rise to > -2 ℃, and self-recovery will begin.
Error E06
Cause:
The battery temperature rises to > 48℃ while charging.
E06 Solution:
Stop charging the machine, let it cool down to < 38℃, and self-recovery will kick in.
Error E07
Cause:
The battery temperature drops to < 0℃.
E07 Solution:
The battery temperature needs to reach > 5℃ for self-recovery to start.
Error E09
Cause:
The machine’s total voltage drops too low, to < 9.6V.
E09 Solution:
Rise the machine’s temperature to > 10.5℃, charging will recover.
Error E18
Cause:
The PV input hits over voltage at > 45V.
E18 Solution:
Lower the voltage to < 40V and self-recovery will begin.
Error E25
Cause:
The battery reaches over-voltage due to the DC 12V output being > 13V.
E25 Solution:
Press the button to recover.
Error E26
Cause:
The sink temp load power goes to >140W due to DC12V-1 output overload.
E26 Solution:
Press the button to recover.
Error E27
Cause:
The DC12V-1 output provides too much current, at > 11A. Or, there is a short circuit.
E27 Solution:
Press the button to recover.
Error E28
Cause:
The DC12V-1 input has too much current, at > -1A.
E28 Solution:
Press the button to recover.
Error E29
Cause:
The DC12V-2 output has been overloaded. The load power has reached > 75W.
E29 Solution:
Press the button to recover.
Error E30
Cause:
Over-current of the DC12V-2 output at > 6A or there is a short circuit.
E30 Solution:
Press the button to recover.
Error E34
Cause:
The machine’s system has overloaded and the DC output stops when total power is > 420W for 3 mins.
E34 Solution:
Press the button to recover.
Error E36
Cause:
The inverter output has overloaded. Power has reached > 300W for 2 mins or the power reaches > 450W.
E36 Solution:
Press the button to recover.
Error E37
Cause:
Over-current of the inverter output when current reaches > -1A or the AC output short-circuits.
E37 Solution:
Press the button to recover.
Error E38
Cause:
The system has been overloaded due to excess power. The AC output has stopped, and total power reaches > 420W for 3mins.
E38 Solution:
Press the button to recover.
These error codes and fixes should help get your power station back online. However, if you still have trouble fixing your Bluetti AC50S 500Wh after trying these, contact their customer service department for more answers.
