please confirm:
· whether the AC circuit breaker is disconnected
· whether the AC terminal is in good connection
· whether the power supply line is normal
· whether the safety regulation settings are
normal
Disconnect the inverter from the utility
grid and the PV array, and reconnect it
after LED turns off. If this fault is still being
displayed, please contact the service.

Check the open-circuit voltages of the
strings and make sure it is below the
maximum DC input voltage of the
inverter. If the input voltage lies within the
permissible range while the fault occurs,
please contact the service.
