IMPORTANT! Surge rated loads, ie) 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.

PCS and service lights off.
Low SOC shutdown in backup mode. See section 5.2 to restart the system.
Low SOC shutdown initiated while out of service. See troubleshooting – section 7,
“service light on in backup mode”.
5.2 Restarting the battery system after low battery shutdown
The system will shutdown 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.

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.
Note: If necessary, the load circuits can be shut off inside the backup panel to increase the battery charge
rate. Do not shut off the PV circuit.
