Suggestion
1. Remotely monitor the system for 30
minutes to check whether other
exceptions (such as abnormal
temperature, abnormal battery
voltage, abnormal battery
temperature, and exhaust fan startup)
occur. If yes, ensure that the ESS is
shut down. During remote monitoring,
do not approach the battery cabin or
open the cabin doors.
2. If no exception is found during the
remote monitoring, assign trained
personnel to the site and observe the
system for 30 minutes from a safe
distance. If there is smoke or fire,
remotely power off the system,
evacuate onsite personnel as soon as
possible, and call the fire emergency
service.
3. If no exception is found during remote
monitoring and onsite observation,
manually clear the alarm. If the alarm
clearance fails, contact your technical
support.
1. Check whether the air conditioners in
the battery cabin are faulty.
2. Check whether the doors of the
battery cabin are completely closed.
3. After the battery cabin temperature
and battery rack temperature drop to
below 58°C, manually clear the alarm.
If the alarm persists, contact your
technical support.
1. This alarm indicates that the cabin
needs to be dehumidified. Ensure that
