Charging with AC

EP500 - Charging with AC:
Bluetti is only charged with a maximum of 540 watts. Where or what is the error?

DSP= 4009.02
ARM= 4010.03

What does error 038 mean when starting?

Hi @itse , EP500 AC charging charging power is about 600w, and 540W is normal and please don’t worry.
Report 038 is which kind of situation reported? Can the machine be used normally after the alarm is clear?
