Critical
The alarm is
automatically
cleared when
the battery
voltage is
lower than
58 V.
The battery
voltage is
greater than
60 V for 3s.
The system
shuts down
the inverter
and transfers
to bypass
mode.
•Possible cause: The
battery is faulty.
Measure: Replace
the battery or
discharge the
battery to a normal
voltage.
•Possible cause: The
sampling is faulty
due to
environmental
factors.
Measure: Send the
device to the
maintenance center.

The system
cannot supply
power in
battery mode.
If this alarm
is generated
