Backup Circuit (Optional); System Limitations - Redback SH5000 Owner's Manual

6.6

Backup circuit (optional)

The SH5000 can directly control and power one circuit, known as the backup circuit. This feature is used to extend the run time
of a small number of low power or occasional use devices that you have prioritised for use during a power outage.
• During a grid outage, the SH5000 powers the backup circuit from batteries and or solar.
If grid supply is available, the inverter chooses the power source from solar, batteries or grid.
•
Adding a backup circuit to your home requires planning to maximise the benefits of your investment. A new, dedicated circuit
will give a better result than re-purposing an existing circuit. Your system designer can help you specify an affordable system
that balances cost and performance, based on your expected usage patterns and your backup expectations i.e. what you expect
to run, and for how long.
Loads on the backup circuit must be carefully selected to extend the backup power availability, noting:
Battery storage capacity and availability.
•
• Inverter power delivery limitations.
o Up to 4600W continuous.
o Up to 6900W for up to 10 seconds.
Inverter behaviour during overload events.
•
• Inverter behaviour during high temperature events.
o Above 45 C ambient, power output is reduced.
°
o Above 60 C, the inverter will shut down.
°
A battery is required for best performance. Solar-only power is not satisfactory—backup load and solar power are variable and
unpredictable—when backup load exceeds the available solar power the inverter will automatically shut down and restart.
To ensure some backup, a portion of the battery storage can be reserved, powering the backup circuit until the battery reaches
the minimum State of Charge (SoC). The size of the reserve can be varied according to your needs e.g., more for backup means
less for daily use. See Section 8.3.

System limitations

Your Redback SH5000 Smart Hybrid Inverter and Battery Enclosures are not suitable for:
• Batteries other than Pylontech US2000 or US3000.
Off-Grid installations (the grid is intentionally disconnected).
•
Lithium-ion batteries have a finite number of charge/discharge
cycles available. Off-grid installations cycle more frequently,
reducing battery life.
• Locations without internet access: the system can operate off-line
but is unable to send you fault notifications. You will be unable to
review consumption or performance; make informed decisions about system settings or consumption patterns;
change settings; or remote control the system. You may also affect your warranty coverage if the system is offline for
extended periods
Prediction of your energy bills. The Redback meters are not Utility Grade: they provide a good indication of energy
•
consumption; however, readings may vary slightly from the Network meters used for billing.
Use with generators.
•
• Use with 5Ghz Wi-Fi networks.
WARNING! This equipment is
NOT intended for use with life
support equipment or other
medical equipment or devices.
