15 Troubleshooting
System faults are reported and logged in the monitoring system. All fault logs are also accessible remotely by
your installer.
IMPORTANT! Contact your system installer immediately if any of the following conditions are present
on the front display of the inverter panel.
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
flashing
System is attempting to communicate with the battery modules. Notify service personnel
if this condition persists more than 30 minutes.
All panel lights
OFF
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.
