AC300 will turn off AC out when reconnected to the grid

Product Discussion BLUETTI AC Series

AC300 is running fine, then grid power is lost, AC output is still on, all is still good. But when grid power is restored the AC300 turns off the AC output with an error of 011 H-Bus Voltage High.
Is this designed this way to turn AC off when grid power is reconnected? Does not seem correct.

  2. Try to reduce the AC input current before AC input, and see if it will report 011
