AC200max has 026 and 034 error codes (low voltage and BMS communication errors)

Brand new out of the box AC200max has 026 and 034 error codes (low voltage and BMS communication errors) immediately after being powered on. The AC adapter and the PV350 neither option charge the AC200max. AC adapter charging indicator LED never changes to red. AC200max recognizes the AC and PV charing options with regards to voltage but it never recognizes the watts input. Any help would be appreciated since Bluetti support has yet to reach out. Thanks in advance.

Hi @42Pros , Sorry for inconveniece caused.
Can you first check if the BMS communication cable is plugged in place and not loose?
If the communication cable is plugged in properly, please clear the alarm, remove the load and reboot to see if the error continues to be reported?

I must be missing something because I thought that the AC200max doesn’t have or need a BMS coms cable BECAUSE ITS AN INTERNAL BATTERY. Any rate, Customer Service has reached out and they are replacing the AC200max.

Received, thanks for the updates.
