Severity

2038 Unstable Grid
Frequency
Major Cause ID=1
Power grid exception: The
actual grid frequency
change rate does not
comply with the local
power grid standard.
1. If the alarm occurs
occasionally, the power grid
may be abnormal
temporarily. The inverter
automatically recovers after
detecting that the power
grid becomes normal.
2. If the alarm occurs
frequently, check whether
the power grid frequency is
within the acceptable
range. If not, contact the
local power operator.
2039 Output
Overcurrent
Major Cause ID=1
The power grid voltage
drops dramatically or the
power grid is short-
circuited. As a result, the
inverter transient output
current exceeds the upper
threshold and therefore
the inverter protection is
triggered.
1. The inverter detects its
external working conditions
in real time. After the fault
is rectied, the inverter
automatically recovers.
2. If the alarm occurs
frequently and
aects the
energy yield of the power
plant, check whether the
output is short-circuited. If
the fault cannot be
rectied, contact your
dealer or Huawei technical
support.
2040 Output DC
Component
Overhigh
Major Cause ID=1
The DC component of the
inverter output current
exceeds the specied
upper threshold.
1. If the exception is caused by
an external fault, the
inverter automatically
recovers after the fault is
rectied.
2. If this alarm occurs
frequently and aects the
energy yield of the PV
plant, contact your dealer
or Huawei technical
support.
