7 System Maintenance
Suggestion
1. If the battery fault indicator is
steady on or blinking, contact
the battery supplier.
2. Check that the battery
enable/power/communications
cable is correctly installed, and
that the communications
parameters are the same as the
SUN2000L RS485
configurations.
3. Check that Auxiliary Power
switch on the battery is on.
4. Send a shutdown command on
the app. Turn off the AC
output switch, DC input
switch, and battery switch.
Then turn on the battery
switch, AC output switch, and
DC input switch in sequence
after 5 minutes.
5. If the alarm persists, contact
your supplier or Huawei
technical support.
1. Turn off the AC and DC
switches on the SUN2000L
and disconnect the peripheral
from the Alarm port. Then
power on the SUN2000L
again and clear the alarm
manually. If the alarm persists,
contact your supplier or
Huawei technical support to
rectify the fault. If the alarm is
cleared, it indicates that the
port on the SUN2000L is
normal. Then check that the
pins in the power port on the
peripheral are not
short-circuited.
2. Replace the peripheral, and
then start a self-check to check
that the port functions
properly.
