RedEarth Energy Storage is an Australian-owned and operated manufacturer of energy storage systems
Co-founded by CEO Charlie Walker, CTO Chris Winter, and non-executive director Bruce Ebzery in 2013, RedEarth Energy Storage began as a
start-up doing research and development into battery energy storage systems specifically for the Australian market.
Starting in the off-grid environment with the development of BlackMax, RedEarth has since added on-grid, commercial and industrial, and
residential systems to its suite of products, all designed to be modular and scalable to allow the end-user customer to update their systems
should their needs change.
RedEarth operates with the belief that electricity will be the primary energy source in the future, and that every business and residence can
generate more clean, green electricity than it can consume – meaning they can financially capitalise on their excess solar energy.

The CopperHead must only be installed by suitably qualified personnel who have read and are familiar
with its operation and hazards.
The battery provided with this system must be charged only by the Selectronics inverter. Do not attempt
to charge the batteries with any other charger device or connect any devices directly to the DC battery
bus unless approved by RedEarth.
In the event of a fire evacuate the area and call emergency services. A dry
agent fire extinguisher should be readily available and used. DO NOT use
water.
Note: MSDS document is provided with the system and can be found at
www.redearth.energy
Do not use a damaged battery. Batteries should only be disposed of at an appropriate recycling centre.
Please contact RedEarth for advice.
A battery can present a risk of electrical shock and high short-circuit current. The following precautions
should be observed when working on batteries:
 Disconnect charging source prior to connecting or disconnecting battery terminals.
In our efforts towards constant product enhancement, this document is subject to change at any time.

Overview
The RedEarth CopperHead is an Australian-made ready-to-run energy storage system for On or Off-Grid, three-phase
applications.
The system is designed to be easy to install and use. It is assembled and factory tested
prior to shipment and requires only limited programming on-site.
It uses Selectronics SP Pro battery inverters together with RedEarth’s TROPPO 4841
lithium batteries (LFP). As standard it is combined with Selectronic-certified Fronius
inverters making it an AC-coupled system. DC-coupled options with AERL MPPTs are
possible.
It is supplied with everything needed to connect the PV Solar array and a generator
(either 2-wire auto start or manual start), or the grid for grid-connected systems.
The CopperHead is designed to be installed outside in a shaded area. It has an IP54 rating and Is fitted with two replaceable air-
conditioners for hotter climates. A changeover switch is included in case there is a problem with the system. In this case the
loads are run solely off a generator (or the grid) until the system is operational again.
Remote monitoring is available subject to mobile phone coverage. This uses RedEarth’s EMU app. Starlink satellite Internet is an
option where no mobile coverage is available. Selectronics Select.Live monitoring Is also available.
CopperHead installations require the electrical connection of:
 The customers load – there are dedicated terminals inside the unit
to connect to.
 The AC outputs of the externally mounted Fronius PV inverters.
 Generator or Grid - there Is dedicated MCB as well as generator
auto-start and generator battery trickle charger terminals inside the
unit to connect to.
 Remote monitoring uses RedEarth's RedPi edge device as well as
Selectronics SelectLive- The RedEarth supplied RedPi has a built-in
SIM-card (requires mobile coverage), otherwise connect the internet
via LAN cable. Optional Starlink satellite connection can be arranged.
For a smooth installation, RedEarth offers installer training as well as tech-support during installation. RedEarth also requests
that the Installer contact RedEarth's Tech Support during installation once the system Is turned on. This confirms the remote
monitoring Is fully operational.
During factory testing all parameters are pre-set for correct operation between the SP Pro inverter, the Fronius PV inverters and
the battery bank. However, some parameters may need to be adjusted during installation (e.g., generator size, maintenance run
time, etc). Please consult this manual as well as the Selectronics Manual and comprehensive Selectronics website for additional
information if required.
NOTE: The CopperHead is not designed to act as a main switch board for the site, as it does not include space for additional
main & customer circuit breakers or RCDs. The MEN link and Earth connection need to be installed as per AS/NZS 3000:2018.
NOTE: Selectronics allows more complex installation options (such as dual phase or high-power grid T-connections) To Install
these, the installer should have experience with Selectronics and have received training directly from them. RedEarth primarily
supplies and supports our standard configurations.

The “AC Switchgear” shown below contains all the AC protective and isolation points as well as the changeover switch. Each
device is labelled for easy identification.
Removing the cover panel in the front section exposes all the cable connection points and switch gear wiring, as shown below
on the right.
The 22.5kW CopperHead (3x7.5kW inverters) is available with a minimum of 12 batteries (49.2kWh) up to 33 batteries (135kWh
nominal capacity). Each battery has a capacity of 4.1kWh.
An optional 15kW CopperHead is available (3x5kW inverters) can be provided with a minimum of 9 up to 33 batteries (4.1kWh
per battery), which provides from 36.9kWh to 135.3kWh nominal capacity.
The rear of the enclosure contains three bays of 19inch racks where the batteries are installed. Screws secure the batteries in
place.
NOTE: The CopperHead Is usually shipped without the batteries Installed. When installing the batteries distribute them evenly
across the three racks, starting from the top.
Due to the characteristics of RedEarth’s TROPPO lithium battery, it is possible to install additional batteries in your system at
later date. Please contact RedEarth to purchase extra TROPPO batteries.
The enclosure is pre-wired with battery cables for all 33 batteries via the bus-bar system. This makes adding additional batteries
a simple process of plugging in the spare battery cables into the connectors on top of each battery.
