Pylontech US2000 or US2000Plus
Pylontech batteries use an integrated Battery Management System (BMS) to manage ultimate charge and discharge rates
(protecting the batteries from heat damage) and inform the Smart Hybrid System of status. The BMS also protects the batteries
from total discharge, assisting system reliability and longevity.
Your installer may identify batteries as Master, 1, 2, 3 etc up to 8. This refers to the position of individual batteries in the BMS
chain of command, where the first connected battery is the Master, which controls subsequent batteries.
The battery identity may also indicate the physical position of the battery within the enclosure, though this is an installer
preference. The diagram below indicates the BMS battery naming convention and recommended battery locations.

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.
oUp to 4600W continuous.
oUp to 6900W for up to 10 seconds.
•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.
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
medi
cal equipment or devices.

Introduction
12 Owner’s Guide – Redback Smart Hybrid System – v3.8
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, and occasional maintenance is all that is required.
Alternatively, you can dive deep into your data and make informed decisions to optimise your system and maximise the return
on your investment.
Either way, the first step to getting the best from your system is to look after it.
8.1 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 150mm 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 13. 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 or Redback portal present helpful charts, enabling you
understand 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, and remote support will be limited. You may also
affect your warranty coverage if the system is offline for extended periods

Redback Technologies
Owner’s Guide – Redback Smart Hybrid System - v3.8 13
8.2 Monitor performance
Redback offers two choices for monitoring the energy performance of your household.
8.2.1 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 from your app store, for
Android 7 or higher, or iOS 12.1 or higher. Use the app to:
•Check your home energy usage.
•Reconnect your system to the internet.
•Review your system performance - but you will need to contact your installer if
changes are required.
8.2.2 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.

Introduction
14 Owner’s Guide – Redback Smart Hybrid System – v3.8
8.3 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.
8.4 Getting the best from your relays
Your inverter can control up to four 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 an 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 Smart Hybrid System - v3.8 15
8.5 Getting the best from your backup circuit
Your SH5000 inverter includes one backup circuit 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
4600W, 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 6900W for up to 10 seconds: this is useful for devices that have high starting power, but low
power demand when running.
The inverter will reduce power output above 45°C ambient and shut down above 60°C.
If the system battery reaches minimum SoC 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.

Troubleshooting
16 Owner’s Guide – Redback Smart Hybrid System – v3.8
Inverter operation
Your SH5000 inverter has sophisticated software controls available in the MYRedback app or the Redback portal, however there
are some physical controls or functions at the unit.
9.1 Locking up the batteries
Secure the battery enclosure to:
•Prevent unauthorised access to the batteries and
cabling.
•Discourage battery theft.
The enclosure is 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.
9.2 Inverter – Changing bypass modes
The Bypass switch controls the power to the BACKUP AC isolator and the EMS. 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 or not operating reliably.
If grid supply is lost the inverter will not supply the backup
circuit.
Middle
Backup circuit and EMS are
isolated (depowered).
Used to restart the EMS.
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 SoC.

9.3 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.

9.4 Inverter restart
Occasionally, it may be necessary to cold boot the inverter, to restart all software. A restart briefly interrupts all inverter
functions, noting that PV, battery, and grid supplies remain energised to the isolators.

9.5 EMS restart
Occasionally, it may be necessary to restart the EMS software. A restart will reboot the EMS, without needing to restart the
whole inverter, noting that the backup circuit will be briefly interrupted.
DO NOT restart unless instructed to do so by Redback support staff.
STEP
PROCEDURE
COMMENT/ILLUSTRATION
Open the BoS switchgear hatch.
Identify the three-position Bypass switch. Note the position of the
switch.
☐Up ☐Down
Note: The switch is usually returned to the original position during
restart.
Set the Bypass switch to the middle position (OFF).
Wait 5 seconds.
Return the Bypass switch to its original position (if noted)
otherwise place in the DOWN position. The EMS will restart in
approximately 10 minutes, indicated by the EMS LEDs stabilising
to:

Inverter operating modes
The inverter operating modes are summarised below. Select modes using the Redback app or portal.
10.1 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 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)
10.2 Standby mode
STANDBY mode is invoked automatically when no solar
or battery energy is available. The SH5000 directs grid
power directly to the AC Loads thereby minimising
energy losses in the inverter e.g. heat.
The SH5000 automatically reverts to the previous mode
of operation when solar or battery energy is available.
10.3 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 4.6kW.
AC Loads are fulfilled by the grid.
