1. Check the ventilation and
whether the ambient
temperature of the solar
inverter exceeds the upper
limit. If the ventilation is
poor or the ambient
temperature is too high,
improve ventilation.

ambient temperature meet
requirements yet the fault
persists, contact your
dealer or Huawei technical
support.
Turn off the AC output switch
and DC input switch, and then
turn them on after 5 minutes.
If the fault persists, contact
your dealer or Huawei
technical support.
