Welcome
Congratulations on the purchase of your new Redback system, including a Redback ST10000 Smart 3-Phase Hybrid Inverter and
one or two Redback BE14000-HV High Voltage Battery Enclosures. Our products are designed and manufactured to our high-
quality standards and will provide years of service.
The system’s goal is to maximise the use of your self-generated solar energy while minimizing the amount of energy consumed
from the grid.
This manual describes the features, use and maintenance of your Redback system.
Introduction
Your Redback system coordinates up to three solar arrays, battery storage, grid supply and your home, including a backup
circuit and up to three relay-controlled devices.
The energy produced by the solar array is automatically directed to the battery, your home and/or the utility grid for the
highest performance and best economic return.
The backup functionality enables users to have continued supply of electricity to the backup circuit in the event of a utility
power outage.
The MYRedback app and the Redback portal provide a comprehensive view of the energy consumed or generated by your
home, providing the information required to fine-tune your system settings or optimise your energy usage patterns.

Batteries
Your Redback system has a storage capacity of up to 28kWh using 4 or 8
Pylontech lithium-ion batteries and one or two BE14000-HV Battery
Enclosures. Batteries are serial connected, and all batteries must be in
serviceable condition. The allowable battery combinations are shown at
right, noting that all batteries must be the same models i.e., no mixing
models.
Your Redback system is fitted with a Pylontech Battery Management
System (BMS) to manage battery performance (protecting the batteries
from heat damage). The BMS also protects the batteries from total
discharge, assisting system reliability and longevity. The BMS also
monitors the Battery Enclosure temperatures and activates fans as
required.
Your installer may identify batteries as 1; 2; 3; 4 etc. This refers to the position of individual batteries in the BMS chain of
command—the first connected battery is number 1.
The diagram below indicates the BMS battery numbering convention and locations.

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.
oUp to 10kW continuous,at any time, including when grid is connected.
oUp 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.
oAbove 45°C ambient, power output is reduced.
oAbove 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
WARNING! This equipment is
NOT intended for use with life
support equipment or other
medical equipment or devices.

Getting the best from your system
12 Owner’s Guide – Redback ST10000 and BE14000-HV – v1.6
Getting the best from your system
Your Redback system is designed to operate autonomously – the level of interaction is up to you.
A set-and-forget approach will work fine: occasional maintenance is all that is required.
Alternatively, you can dive deep into your data and make informed decisions to optimise your system and lifestyle to maximise
the return on your investment.
Either way, the first step is to look after your Redback.
Keep your system in good condition
Keeping your system in good condition maintains efficiency, increases longevity, and helps us help you, if the need arises. There
are three key items requiring your attention.
Cooling
Your system uses fresh air to cool the inverter and batteries.
If your system becomes too hot its efficiency decreases, and
it may even shut down.
There must always be 100mm of clear space beside and
above your system. Ensure no items are left near the base
of the system or placed on top of the inverter, as vents will
be obstructed.
The system must not be enclosed i.e., do not build a cabinet
around it.
Maintenance
Complete the annual maintenance items in Section 10. In
very dusty conditions you may need to clean the filters
more frequently.
Internet connection
Data is required to get the best out of your inverter. A
permanent internet connection enables the inverter to send
data to the Redback cloud, where the MYRedback app and
Redback portal present helpful information, enabling you to
see your system’s performance. Your installer or Redback
can also use the data to diagnose problems or suggest
improvements to settings, based on your actual usage.
Note: Your inverter will continue to function without an
internet connection, but you will be unable to receive any
fault notifications, no data will exist for the period of
disconnection, software updates will not occur, and remote
support will be limited.

Redback Technologies
Owner’s Guide – Redback ST10000 and BE14000-HV - v1.6 13
Monitor performance
Redback offers two choices for monitoring the energy performance of your household.
7.2.1 MYREDBACK APP
MYRedback provides a simple, up-to-date view of what’s happening at your place – it’s great for
quickly checking the energy flow at home. MYRedback is available for Android 7 or higher and iOS
12.1 or higher. Use the app to:
•Check your home energy usage.
•Reconnect your system to the internet.
•Review your system settings- but you’ll need to contact your installer if changes are
required.
7.2.2 REDBACK PORTAL
The Redback portal portal.redbacktech.com offers all the features of the MYRedback app plus a comprehensive history of your
systems performance, much greater detail about your system, and direct access to support documents.
DASHBOARD
The dashboard view provides an overview of your system:
•Energy consumption trends
•Power demand
•Power being bought or exported
•Power from solar
•Power to/from batteries
•Stored energy
If nothing else, you should view the Renewable Energy Meter regularly; it
shows the system’s impact on your energy consumption during the past 7,
30 or 90 days. If it falls below 60%, it’s worth reviewing your usage habits or
your system size and settings.

Getting the best from your system
14 Owner’s Guide – Redback ST10000 and BE14000-HV – v1.6
Getting the best from your batteries
Your batteries will do a great job of looking after themselves, with no intervention required if they have the correct State-of-
Charge (Soc) settings for your needs.
Setting name
Comment
Minimum SoC
%* In day-to-day use, your batteries may discharge
down to this % of total capacity.
Minimum SoC
Offgrid %
*
This is the deep discharge limit- it protects the
battery from damage due to over-discharge
during a
backup event i.e., during a blackout.
*State of Charge: The battery manufacturer will specify the lowest acceptable value.
Backup Reserve
Your system configuration and backup requirements will determine your
settings, which create the Battery Usage Plan, as shown right.
The Backup Reserve is the energy withheld for use by the backup circuit
during a grid outage event.
Backup Reserve = (Minimum SoC – Minimum SoC Offgrid) %
The Backup Reserve is a balancing act: A large reserve increases the backup
run-time when needed but may decrease the everyday use of self-
generated energy.
Put another way, it’s blackout security v. energy cost.
Think about your own needs, then ask your installer to adjust the Minimum
SoC according to your priorities.
Getting the best from your relays
Your system can control up to three optional relays - usually used to turn specific equipment ON or OFF remotely, or ON and
OFF according to a once-off or daily schedules. The objective is to move power usage into daylight hours, after batteries have
charged, and when excess solar power is being exported or not used at all. Typical applications are pool or water tank pumps,
and hot water systems.
To use this feature, ask your electrician to install a dedicated, relay-controlled circuit for the equipment.
The schedules are created in the Redback portal, under the CONTROL tab. Multiple daily events are permitted excepting that
they may not overlap and must start and finish on the same day. Manual control is also possible, using the ON and OFF controls.
Frequent deep discharging will shorten
the life of your battery. If you
experience frequent blackouts in your
area, ask your installer to set the Minimum SoC
higher than usual. This extends your backup
run-time and reduces the number of deep
discharge events.

Redback Technologies
Owner’s Guide – Redback ST10000 and BE14000-HV - v1.6 15
Getting the best from your backup circuit
Your inverter includes a backup circuit that is activated during a grid
outage and powered by the system batteries and or solar. The Inverter
can provide power to the backup circuit if:
•Power is available from batteries or solar, and
•Total household, continuous power demand is less than
10kW, and
•Total power demand is less than the power available from
batteries and solar.
Generally, you should connect and use the minimum number of devices at any one time.
Only essential or low consumption devices or appliances should be connected to the backup circuit. Devices that require high
currents should not be connected as they may trip the inverter or rapidly discharge the batteries. The table below lists the
suitability of common devices.
The inverter can fulfil demand of 16.5kW for up to 60 seconds: this is useful for devices that have high starting power, but low
power demand when running.
The inverter will reduce power output below -10°C or above 45°C ambient and shut down above 60°C.
If the system battery reaches minimum State of Charge during a grid outage the inverter will attempt to fulfil the backup circuit
demand from Solar- if demand exceeds available solar power the inverter will shut down automatically. Solar is unpredictable—
it varies with cloud cover—so this situation is best managed by minimizing devices in use.

Solution: Minimise devices in use.

Inverter operation
16 Owner’s Guide – Redback ST10000 and BE14000-HV – v1.6
Inverter operation
Your Redback inverter has sophisticated software controls available in the Redback app or portal, however there are some
physical controls or functions at the unit.
Locking up the batteries
Secure the Battery Enclosures to:
•Prevent unauthorised access to the batteries.
•Discourage battery theft.
The battery enclosures are secured by trapping the Front Covers: clamps at either
side are padlocked in position, restricting access to front cover fasteners, and
resisting forcing of the covers. Note: The security clamps will discourage a casual or
opportunistic intruder but will not stop a determined thief.
EMS restart
Occasionally, it may be necessary to restart the EMS. A restart will reboot the EMS,
without needing to restart the whole inverter, noting that the Backup circuit will
be briefly interrupted.
To restart the system, press the switch concealed under the spider.
Inverter – Changing bypass modes
The BYPASS switch controls the power to the BACKUP AC isolator. Its primary use
is to manually connect the backup circuit directly to grid supply, when required.
Position
Function
Comments
Up Power to the backup
circuit is from the grid
supply only.
The Inverter no longer
controls the backup circuit.
This mode ensures grid supply to the backup circuit if the
inverter is not available; not operating reliably; or if a large,
temporary load must be placed on the backup circuit.
If grid supply is lost the Inverter will not supply the backup
circuit.
Middle Backup circuit is isolated
(depowered).
No power is sent to the backup circuit.
Down Power to the backup
circuit is supplied and
managed by the Inverter,
from any source.
This is the recommended Operational mode.
If grid supply is lost the Inverter will continue to supply the
backup circuit from the batteries and PV- the entire system will
shut down when the batteries reach the minimum state of
charge.

Redback Technologies
Owner’s Guide – Redback ST10000 and BE14000-HV - v1.6 17
Shutdown procedure
Occasionally, it may be necessary to shut down the inverter interrupting all inverter functions, noting that PV, battery, and grid
supplies remain energised to the isolators. Follow the procedure below to shut down your system.

Inverter operation
18 Owner’s Guide – Redback ST10000 and BE14000-HV – v1.6
Start procedure
Start your inverter as shown below.

Redback Technologies
Owner’s Guide – Redback ST10000 and BE14000-HV - v1.6 19
Inverter operating modes
The inverter operating modes are summarised below. Select modes using the Redback app or portal.
Auto mode
AUTO is the default operating mode, maximising
consumption of self-generated and stored energy. If the
inverter mode has been changed, AUTO can be
reselected from the Redback app or portal.
If AC loads (House) exceeds solar generation, energy
sources are prioritised as follows:
1. Solar
2. Battery
3. Grid
If solar production exceeds AC loads, destinations for
self-generated energy are prioritised as follows:
1. AC Loads
2. Battery (storage)
3. Grid (if enabled)
Standby mode
STANDBY mode is invoked automatically when no solar
or battery energy is available. The inverter directs grid
power directly to the AC Loads thereby minimising
energy losses in the inverter e.g., heat.
The inverter automatically reverts to the previous mode
of operation when solar or battery energy is available.
Charge battery mode
CHARGE mode may be used to prepare for a severe
weather event, and prioritises charging the battery at
the nominated rate, from the grid.
Any available solar will supplement the grid charging up
to a maximum charge rate of 10kW.
AC Loads are fulfilled by the grid.

Inverter operation
20 Owner’s Guide – Redback ST10000 and BE14000-HV – v1.6
Discharge battery mode
DISCHARGE mode is user selectable in the app or portal,
and prioritises battery discharge to the following:
1. AC loads
2. Grid
Battery discharge is at the nominated Discharge Power,
supplemented by solar.
•If AC Loads exceed (Battery + Solar), energy is
imported from the grid.
•If (Battery + Solar) exceed AC Loads, excess
energy may be exported to the grid.
•If (Battery + Solar) exceeds (AC Loads + LEP)
the battery discharge is prioritised, at the
maximum possible rate, up to the nominated
Discharge Power.
Backup mode
BACKUP mode starts automatically when the grid supply
is interrupted (default setting).
In BACKUP mode, the inverter provides energy to the
backup circuit only. Energy consumption from solar is
prioritised and excess solar charges the batteries.
To maximise the effectiveness of the backup circuit, the
circuit should only support essential appliances such as
refrigerators, or low energy devices such as fans,
computers, tablets, or phones.
BACKUP mode is invoked within 0.05 seconds of a grid
interruption. BACKUP mode reverts to the previous
mode when the inverter detects grid supply has been
restored for over 1 minute.
BACKUP mode may also be known as “Stand-alone
Mode”.
Note: If available Battery and Solar power is less than
the detected Backup Load the inverter will consider this
an overload and will automatically shut down.
The inverter will restart after approximately one
minute. If overload persists, the cycle will repeat.
