Solution
1. Check the ventilation and
ambient temperature at the
inverter installation position.
2. If the ventilation is poor or
the ambient temperature

improve the ventilation and
heat dissipation.

ambient temperature meet
requirements yet the alarm
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 alarm persists, contact your
dealer or Huawei technical
support.
