Hello Bluetti and Fellows,
what does this error mean.
Which BUS?
What does the preceeding number (ie: 01 012 or 00 012) mean?
In my case the the first error is “01 012” and after clearing the error protocol then the “00 012” appears. Why?
Why can’t the AC Output reactivate without clearing the whole error protocol?
I don’t want some simple answers.
At this point, I wish to get serious technical answers.
Because I have to stand up to my grid operator.
PICS:
Based on the userguide, it looks like you might have a voltage above a warning threshold. Reboot, see if it persists… contact support if it does.
Bingo!
What the topic of the thread says…
I wanna know which bus has high voltage and how can this happen.
I want to get real technical support and not dump psychological support.
And I want to get this error through the ble modbus because I don’t sleep besides the AC500 in the basement.
This errors always happens when the AC output load is above 3kW but not more then 5kW.
It seems the promise of 5kW is a empty promise…
Since this errors the ac500 sends strange DC input current values peaks of 0xFFFF (see pic).
@tinking Sorry for my late reply. When the AC is charging, turn on the AC output, and it will report 012 after a while (it does not report 012 as soon as the AC is turned on), right? If so, please check if you have updated it to the latest firmware. Also, please provide me with the SN and the firmware version of AC500. Thank you.
No, it cuts the AC output and simultanously it throws the “01 012” error,
and after a while (some minutes) it throws the “00 012” error.
It always happens when the resistive heating element (2 kW) switches on.
There is one B300S and two B300 conncted.
The B300s is on Bat01 connector and the two B300 are on the Bat02 connector (Bus?).
@tinking You will receive a firmware update notification. Please update it to the latest version and check if the problem can be solved.
@tinking Please update the APP to the latest version, then log in with your account, then follow the below steps:
Yes, I don’t recognised the “connect with bluetooth”. 
Now I updated the DSP and the BMS for the B300s but the IOT upgrade failed permanently.
Now I’m curious if the behavior changes…
And thanks for the support!
@tinking For the IOT Upgrade failed, please try the below steps:
@tinking I’m sorry to hear that. I found from the background records that you did not successfully upgrade the DSP firmware. Can you upgrade it again?
@tinking It seems that I got the wrong information. You have updated the firmware successfully but the error still appears. Please try switching the AC output to 230V to test.
Hi there,
I would like to ask for SW update for my AC500 as well! Getting that 012 error very often.
