6 Maintenance
The Evolve home energy storage system is a maintenance free product. Regularly scheduled inspection of
the airflow path for the active cooling fans on the bottom side of the PCS cabinet is all that is required.
This inspection should occur on an annual basis, or coincide with PV inspection. If the fan vents are
obstructed with dust / debris, a soft-bristled brush can be used to wipe them clean. Do not use any
solvents, scouring, or corrosive materials to clean the unit. Never remove or unplug connections or plugs
during cleaning.
7 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 as recommended below if any of the following conditions are
present on the front display of the energy storage system.
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
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.
