If the inverter
has not started,
the system has
no output, and
inverter startup
is prohibited.
•
If the inverter
has started, the
inverter still
works properly,
but the system
cannot transfer
to bypass mode.
Possible cause: The bypass input
three
-phase sequence is incorrect.
Measure: Check that bypass input
power cables are correctly connected.

An alarm is
generated, and the
battery lifespan is
affected.
Possible causes:
•
The configured number of
batteries is less than the actual
number.
•
The battery string charge voltage
exceeds the upper threshold.
Measures:
•
Check battery parameter settings.
• Check the charger. When batteries
are disconnected, check whether
the charger voltage is normal. If

The UPS shuts
down.
The UPS transfers
to another working
mode or shuts
down.
Possible causes:
•
The mains experiences
instantaneous high-
voltage impact.
•
The output has special loads such
as inductive loads and rectification
loads.
•
The output has transformer loads
but the transformer mode is not
set.
•
The hardware is damaged.
Measures:
•
After you rectify the fault, restart
the UPS.
•
Check whether the load type is
supported by the UPS.
•
Enable the transformer mode.
•
Contact Huawei
technical support
for repair.
