9.4 Backup Power Operation
This system will provide backup power to dedicated electrical circuits within the home via a permanently wired electrical
sub-panel, referred to as the backup panel. Backup power is limited in rating and duration, both of which are dependent
on the nature of the loads connected to the system, and the availability of the solar PV supply. This system is designed to
reliably provide power to a refrigerator, home lighting, home electronics, and small appliances.
NOTE: This product is not an uninterrupted power source (UPS). Following a utility outage, a four second power
interruption will occur before the backup power source commences. As a result of this interruption, a desktop or
portable UPS is recommended if continuous operation is desired for any electronic devices.
IMPORTANT! Surge rated loads, i.e. power tools, portable air conditioners, may cause an overload shutdown.
Equipment of this type that is connected to the backup panel should be inspected and tested regularly as per
manufacturer suggested schedules. Permanent damage to the battery system and/or your equipment may
occur if exposed to chronic overloading cycles.
IMPORTANT! Portable extension cords connected to a backup circuit should be limited to 10 meters.
IMPORTANT! This product does not support automatic gas generator integration. Do not attempt to connect a
gas generator to the battery system. If generator support is required, consult your installer regarding a separate
manual transfer to your backup electrical panel.
NOTE: The power output / surge rating will be further limited when the battery is below 10% SOC.
9.4.1 Backup Power Display Modes
Display
Definition
Battery status LEDs indicate the following:
• Charge = flash right. Discharge = flash left.
• PCS and service lights off.
Low SOC shutdown in backup mode. See section 9.5 to restart the system.
Low SOC shutdown initiated while out of service. See troubleshooting – section 7, “service
light on in backup mode”.
9.5 Restarting the battery system after low battery shutdown
The system will shut down when the battery reaches a critically low-level during backup operation.
To restart the system:
IMPORTANT! Ensure there is adequate sunlight for the solar PV system to charge the battery before
restarting the system. If the battery system is installed without a PV system connected to the backup panel, do
not attempt to restart the system. Wait for the utility power to return.
1. Press and hold the service button for 5 seconds.
The backup power will restart, allowing the PV system to
reconnect* and begin charging the battery. The system will continue to operate if the battery charges to its minimal
normal operating range. If the battery does not charge within 15 minutes of restart, the system will shut down to preserve
the battery.
*PV system reconnect time is approximately 5 minutes.
