Suggestion
1. Monitor the ESS remotely for 30
minutes to check whether other
exceptions (such as abnormal ambient
temperature, battery voltage, battery
temperature, and exhaust fan startup)
occur. If yes, shut down the ESS.
During remote monitoring, do not
approach the battery cabin or open
the cabin door.
2. If no exception is found during the
remote monitoring, send 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 the onsite personnel as soon
as possible, and call the fire
emergency number.
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.
1. This alarm indicates that the cabin

minutes, check whether the air
conditioner in the battery cabin is

completely closed.
