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
accidentally, 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
grid frequency is within the
acceptable range. If no,
contact the local power
operator.
2039 Output
Overcurr
ent
Major Cause ID = 1
The grid voltage drops
dramatically or the power
grid is short-circuited. As a
result, the inverter
transient output current
exceeds the upper
threshold, and inverter
protection is triggered.
1. The inverter monitors its
external working conditions
in real time. The inverter
automatically recovers after
the fault is rectied.
2. If the alarm occurs frequently
and aects the power
production of the PV plant,
check whether the output is
short-circuited. If the fault
persists, contact your dealer
or Huawei technical support.

nt
Overhigh
Major Cause ID = 1
The DC component in the
grid current exceeds the
upper threshold.
1. The inverter monitors its
external working conditions
in real time. The inverter
automatically recovers after
the fault is rectied.
2. If the alarm occurs
frequently, contact your
dealer or Huawei technical
support.
2051 Abnorma
l Residual
Current
Major Cause ID = 1
The input-to-ground
insulation impedance has
decreased during the
inverter operation.
1. If the alarm occurs
accidentally, the external
power cable may be
abnormal temporarily. The
inverter automatically
recovers after the fault is
rectied.
2. If the alarm occurs frequently
or persists, check that the
impedance between the PV
string and ground is not
below the lower threshold.
