Overview
RedEarth's BushChook home battery system is your complete solution for both on-grid and off-
grid homes. There are models for both single-phase (8kW & 5kW) and three-phase (12kW)
homes.
BushChook is an all-in-one battery system designed to be very easy to install. As an Australian-
made product built in Brisbane, RedEarth provides best-in-class support for BushChook owners
and installers.
The system, including solar panels, generates and stores electricity for use day & night, and
includes a whole-home backup capability so that customer’s loads remain powered during any
blackout (load dependent).
For the homeowner it minimises electricity bills, optimises electricity usage (including electric
vehicle charging) and reduces the homes carbon footprint.
RedEarth also provides the option of ongoing manufacturer support and benefits for 10 years
after the BushChook has been installed by joining RedEarth's
Optimum program.
RedEarth's Optimum program also provides access to
RedEarth’s PPP (Private Power Plant), to generate additional
income such as through Energy Trading or Smart EV
charging. Contact RedEarth for additional information.
The BushChook battery system is monitored and controlled
via RedEarth’s EMU app, available for both Apple and Android
phones.
Installation features:
• The BushChook system can easily be retrofitted to an existing PV solar system that may
already be installed at the home.
• Solar panels: Up to 18kW of panels can be connected to the 12kW 3-phase BushChook
and 12kW of panels to the 8kW 1-phase BushChook. This is usually enough to meet the
needs of a typical home as well as charge an electric vehicle using only electricity
generated at home.
• The BushChook is designed so that additional batteries can easily be added in the future,
right up to eight batteries with a total of 32.8kWh. Buy what is needed now, and add more
later as demand grows, e.g., an electric vehicle is purchased.
RedEarth’s Private Power Plant (PPP)
Transforming your home into a more valuable and lucrative investment is easily achievable
through the integration of RedEarth systems and proprietary Private Power Plant (PPP). As we
step into an electrified future, homes need to be ready. By harnessing the untapped potential of
your rooftop, you can generate up to three times the amount of solar energy needed to power
your residence or business. The result? Your property becomes your very own Private Power

Overview of the installation tasks
A typical complete installation of the BushChook home battery will require the electrical
connection of the following items. If the home is only off-grid then there is no need to connect
the grid or the feed-in meter/CT, but a backup generator will very likely be required.
Note: Differences between 1-phase and 3-phase systems are highlighted where necessary.
1.
Grid:
AC cables run from the MSB (Main switchboard) directly to the grid terminals
inside the BushChook system. In 3-phase system observe the correct phase
rotation.
2.
Feed-in Meter/CT
(supplied) Required for on-grid systems that are not installed as
whole home backup. It is installed in the MSB and connected to the BushChook
system via a Cat5/6 cable or similar (not supplied). The information from this meter
affects the operation of the BushChook system, make sure both the wires and CT
are connected the right way around.
o In addition to the Feed-in meter the MSB will also require a MCB to be installed
to allow the BushChook system to be isolated, for example to work on the MSB.
3.
Load:
AC cables from the MSB directly to the Load terminals inside the BushChook
system.
o
Note:
The BushChook system is designed as a whole home backup system,
however if the loads in a particular house are greater than the capacity of the
BushChook system then the loads inside the MSB will need to be split to ensure
that the backed-up circuits do not overload the BushChook system.
o The BushChook 3-ph is rated at 12kW and the 1-phase at either 8kW or 5kW,
depending on which system was ordered. Loads such as pool pumps and under
floor heating should probably not be backed up.
o Putting too many loads on the backed-up circuit can also empty the battery
quickly during an outage. In this case additional battery capacity may be
required. Note that the BushChook has a multi-purpose SMART Port that can act
as a Smart load which can be programmed to turn off at a pre-determined
battery state-of-charge (SOC) leaving the remainder of the battery capacity for
more critical loads. see details below under
Optional - SMART Port connection.
4.
Solar:
The BushChook has 2 MPPTs. The 5KW 1-phase BushChook accepts up to 2
arrays of PV solar panels, the 8KW 1-phase BushChook accepts up to 4 arrays,
where each tracker accepts two strings in parallel. The maximum string voltage on
the 1-phase systems is 500Vdc. The 3-phase BushChook accepts up to 3 arrays,
where two of these are paralleled into one of the MPPTs. The maximum string
voltage on the 3-phase systems is 800Vdc, although 600Vdc may be the maximum
voltage allowed on a residential installation.
5.
Batteries:
The BushChook is pre-wired for up to eight Troppo batteries. Each Troppo
battery has a nominal capacity of 4.1kWh. The batteries need to be installed and
plugged in.
6.
Remote monitoring:
The BushChook system needs to be connected to the internet
to provide its full capabilities. Note this applies to both on-grid and off-grid
Installations. If no Internet connection is available, then no remote monitoring is
available for the BushChook system. RedEarth provides 4G internet during the first
3-month trial of any BushChook installation. After the 3-month trial the customer can
choose to join RedEarth's Optimum Customer Support program, and the 4G internet
option will continue, otherwise the customer can provide their own internet if they
want remote monitoring.

o A cell phone booster option is also possible in areas with poor mobile phone
coverage. Contact RedEarth for details.
o Hard-wired internet cable from the home internet router to the BushChook
system can be installed if available. This provides the most robust
communication link versus a Wi-Fi or 4G signal.
7.
Optional - SMART Port connection:
The BushChook system has a third AC
connection option, the SMART Port that can perform different functions depending
on how it is configured. It can connect an auto-start generator, but it can
alternatively be configured to either connect and manage a separate AC-coupled
PV inverter OR it can power a "smart load" such as a pool heater or crypto miner.
See notes below.
By Default, the SMART port is configured to operate a Backup
Generator, please notify RedEarth at the time of sale, or installation if you wish to
adjust this
.
o Smart Load: If connecting a smart load, run your designated smart circuit into the
ac breaker labelled Smart / Gen. This load will run when the batteries are above
a programmed state of charge, and power down when the batteries fall below
this SOC. For example, an air-conditioned could be powered via this SMART Port
so that in a power outage it will continue running until the battery reaches a pre-
programmed SOC. The SMART port can also be configured to always provide
power to this circuit when the grid Is connected, independent of the battery
SOC.
o AC Coupled Solar: An AC coupled solar Inverter or micro-inverter can be
connected into the terminal labelled
Smart / Gen terminal
. This opens up the
opportunity to redirect the output of an existing PV system to this port, allowing
it to be controlled by the BushChook system. Note: It is important that the
shutoff frequencies are set appropriately so that the BushChook system can
correctly manage this extra AC-coupled PV system (consult RedEarth tech
support), and it Is also essential that the AC coupled PV does not exceed a 1:1
relationship to the BushChook Inverter size (5kW or 8kW for 1-phase or 12KW
for 3-phase).
o Generator: The SMART port is set to generator in the default configuration of the
BushChook. This mode will automatically call your generator when the SOC
reaches a lower SOC (battery voltage setting), this will then stop the generator
when the SOC reaches the higher SOC (battery voltage setting), If you require
assistance adjusting these two set points contact RedEarth tech support. The
BushChook includes a 2-wire generator auto-start feature. See Section 4.6 for
details.

Key additional tasks to complete the installation include;
1.
Book the install with RedEarth:
When you know the installation date, book the time
with RedEarth so that they are sure to be there to help you and also confirm that the
system and the remote monitoring is properly setup.
2.
Optional - receive training on the BushChook system at RedEarth's facility In
Brisbane.
It Is also possible for RedEarth to provide training at reseller/installer
facilities.
3.
Adjusting the programming of the BushChook inverter
for the customer’s specific
requirements. (e.g. adjust the level of grid-feed allowed by the utility or modifying
the SMART Port function). Use the
Solarman Smart APP
operating in local mode to
access these settings. See STEP 6 - Commissioning the System
4.
Handover to the customer:
this includes demonstrating what circuits are backed up
during an electricity outage (by actually turning off the grid supply) as well as
demonstrating how the backup generator works (if one is installed) and confirming
that it charges the battery system.
5.
Customer to scan the QR code:
This is important for the customer to be able to
monitor their system on RedEarth's EMU app as well as access the benefits of
RedEarth's Optimum and Private Power Plant features. It also registers the warranty.
Note:
The BushChook is not designed to act as the customers MSB as it does not
include space for additional main & customer circuit breakers or RCDs. RCD’s must be
installed in the MSB as required by AS4777.2:2020.

RedEarth’s BushChook Home battery system can
be accessed by removing the lid. To do this,
remove the nine (9) screws with a Philips
screwdriver (PH2), lift and pull the cover away from
the unit and place in a safe location.
Inside Layout
The BushChook is divided into three main areas. On the Lefthand side (LHS) are the batteries, in
the middle Is the Inverter and on the Righthand Side (RHS) are the electrical components and
cable connection points for installation. Prior to leaving the factory the system is tested. It
leaves the factory with the inverter cabling fully connected and ready-to-run. The batteries are
usually removed for transportation.
Battery area
Up to 8 x RedEarth Troppo-4841 Lithium batteries can be installed in
the BushChook.
All eight sets of battery cables are pre-wired into the system. This
makes it very easy to add additional batteries in the future.
Note that the battery modules are usually shipped separately and
installed during installation.
Removal of the cover must only
be done by qualified personnel.
