The alarm
can be
automatic
ally
cleared
for three
times.
After that,
you need
to
manually
clear the
fault or
power off
and
restart the
device.
The DC
component of
the output
voltage is
greater than
200 mV for 20s.
The
system
shuts
down
the
inverte
r and
transfe
rs to
bypass
mode.
● Possible cause: The half-
wave load power is too
high.
Measure: Locate the load
and remove it.
● Possible cause: The circuit
is faulty.
Measure: Send the device to
the maintenance center.

In power-on
mode, the
current
sampling
deviation
exceeds 10% of
the total
sampling range.
The
system
cannot
start
the

device.
The output
voltage is lower
than the rated
voltage by 50 V
for 3s.
The
system
shuts
down
the
inverte
r and
transfe

bypass
mode.
● Possible cause: The
transient load power is
too high.
Measure: Locate the load
and remove it.
● Possible cause: The circuit
is faulty.
Measure: Send the device to
