Backup circuit (optional)
Your Redback inverter can directly control and power a 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, your inverter 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 installer 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 backup power delivery limitations.
o Up to 10kW continuous, at any time, including when grid is connected.
o Up to 16.5kW for up to 60 seconds, at any time, including when grid is connected.
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.
°
Batteries are required for best performance during a grid outage. 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 6.3.
System limitations
Your Redback system is not suitable for:
•
Single- or 2-phase grid supply: 3-phase supply is required, and all
phases must be connected to the inverter.
•
Use with batteries other than Pylontech H48050 or H48074 (which
may not be mixed).
•
Off-Grid installations (where the grid is intentionally disconnected).
Locations without internet access: the system can operate off-line, but you will be unable to review consumption or
•
performance; or make informed decisions about system settings or consumption patterns. Warranty support will also
be affected.
•
Prediction of your energy bills. The Redback meter is a Class 1 meter: it provides 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 network
