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 solar inverter
automatically recovers after
detecting that the power grid
becomes normal.
2. If the alarm occurs
frequently, check whether the
grid frequency is within the
acceptable range. If not,
contact the local power
operator.
2039 Output
Overcur
rent
Major Cause ID = 1
The power grid voltage drops
dramatically or the power grid is
short-circuited. As a result, the
solar inverter transient output
current exceeds the upper
threshold and therefore the solar
inverter protection is triggered.
1. The solar inverter detects
its external working
conditions in real time.
After the fault is rectied,
the solar inverter
automatically recovers.
2. If the alarm occurs
frequently and
aects the
energy yield of the PV
plant, check whether the
output is short-circuited. If
the fault cannot be
rectied, contact your
dealer or Huawei technical
support.

1. If the exception is caused
by an external fault, the
solar inverter automatically
recovers after the fault is
rectied.
2. If the alarm occurs
frequently, contact your
