Maintenance
5.1 Trouble Shooting:
Danger:
The AXIstorage Li SV1 is a high voltage DC system, operated by qualified and authorized
persons only.
Danger:
Before checking the failure, check all cable connections and if the BESS can turn on
normally or not.
Check the surroundings first
No
Problem
Possible Reason
Solution
1
No power output, no
LED on.
Start button pressed too short.
To turn on, push the button
for at least 5s
To black start, push the
button for at least 10s.
The button battery in the controller
is missing or defective.
The power supply of the controller is
in failure
Change
the
controller
module.
The battery voltage is too low.
Make sure there are at least
3 battery modules.
The connector of the base is in
failure
The base is not connected or
needed to change the base
2
After turned on, status
LED is slowly flashing
orange. Others are off.
Self-checking failure.
DC side has a voltage, but the
voltage difference with the battery
system is higher than 20V.
Make sure there is no DC
voltage or set correct DC
voltage before press start
button.
Then follow turn on process.
BMS internal failure.
Use debug tool to further
analysis or change the
controller module.
3
Status LED is fast flashing
orange, others are off.
The time interval after the last black
start is too short.
Wait more than 5 minutes
and try to black start again.
The battery system is under error
condition such as: temperature or
current protection or other error,
thus it does not response black
start.
Make sure there is no other
protection factor. Or use
the debug tool for further
analysis.
4
Buzzer rings
permanently
Relay adhesion or failure.
Completely disconnect the
battery system from any DC
source, then do a restart. If
the problem remains, swap
the controller.
