12 Troubleshooting
System faults are reported and logged in the monitoring system. All fault logs are also accessible remotely by your
installer.
IMPORTANT! Contact a DURACELL POWER CENTER 5 kW service representative as recommended below only after
any of the following conditions are present on the front display of the inverter panel, and the recommended
actions do not resolve the issue.
Condition
Definition
Service light ON in
grid mode
System is prevented from normal operation due to internal fault. Notify service personnel.
Service light ON in
backup mode
If the system faults into service in backup operating mode, there may be an overload condition
which prevents the system from operating safely. If the battery charge level is greater than 20%
(one or more Green LEDs), reduce the load by shutting off circuits in the backup electrical panel,
then press and hold the service button 5 seconds to resume backup power operation. If the battery
low SOC shutdown mode is displayed, shut off all load circuits (keep PV ON) in the backup panel,
and do not attempt to resume backup operation until adequate sunlight is present to provide a
solar charge of the battery.
All panel lights

System is attempting to communicate with the battery modules. Notify service personnel if this
condition persists more than 30 minutes.
All panel lights
OFF after service
button wake
command
This indicates loss of both AC and DC power sources to the PCS. Check the circuit breaker in the
main electrical panel for the energy storage system.
Online monitoring
system not
accessible
Check the internet connection. If connection is via wi-fi, reboot the wireless router, and make sure
the login user and password have not been changed since time of original installation.
Check power to the energy management system via the orange indicator light on the right side of
the panel. Note: the energy management system may lose power after an extended utility outage
where there is not enough solar generation to maintain battery system power.
Note: monitoring system servers may occasionally be down for service. If first attempts are not
successfully, try again the following day before contacting your installer.
