Troubleshooting
1. Turn off the inverter AC
output switch, inverter DC input
switch, and battery DC switch,
and wait for 5 minutes.
2. Check whether the power
cable is securely connected to
the [Battery-1/2 battery
expansion module-1/2/3]
battery expansion modules (the
terminal is loose or
disconnected, or the cable is
disconnected). For details, see
the quick installation guide.
3. After checking that the cables
are correctly connected, turn on
the battery DC switch, AC output
switch, and inverter DC input
switch in sequence.
4. If the alarm persists, contact
your dealer or Huawei technical
support.
1. Check the ventilation and
whether the ambient
temperature of the [Battery-1/2
battery expansion
module-1/2/3] battery
expansion modules exceeds the
upper threshold.
2. If the ventilation is poor or
the ambient temperature is
excessively high, improve the
ventilation and heat dissipation.
3. If the ventilation and ambient
temperature are normal, contact
your dealer or Huawei technical
support.
