Stephen Young AustraliaOptimized Energy Solution
for the Environmentally
Conscious Consumer More and more electricity consumers are becoming environmentally conscious
and they are taking active steps towards renewable energy. This has led to a growth
in individual consumers investing in their own Energy Storage Systems (ESS) in order
to take advantage of renewable energy at times when the sun is not shining.
Below is a story of Stephen, who is one such consumer.“I need a solution that would
meet my energy needs while
also being environmentally
friendly and cost-efficient.”
Stephen Young in New South Wales, Australia, who is very
concerned about reducing his carbon footprint, wanted to
find technologies available to store his excess solar energy
for use at night and on cloudy days. He had solar panels
installed on his rooftop in 2016, and after talking with his
installer and distributor, had energy monitoring software
installed at his home as well, looking to also include an
energy storage system that would complement his solar
system. He belived that it would be a good way to show his
leadership and dedication to the cause of transiting to
After researching alternative energy solutions, he initially
considered a brand which was highly publicized. However,
the size was too large to install at his home and it was not
compatible with the software he was trying to use. Moreover,
he never received a quote from the company. Amidst this
process, his installer recommended LG Chem as a reputable
company with a battery that could be used immediately with
his energy monitoring software (Reposit), and he received a
quote shortly after his request.
Finally, after discussions with his installer, he decided to install
the LG Chem RESU10H (9.8 kWh) battery on an outer wall of
his home in Thirroul, NSW, in April 2017.
Stephen YoungSimple Installation & Sleek Design“The LG Chem RESU10H
was easy to install and
looks good. It’s not overly
intrusive, and it is a real
The entire installation process was smooth for
Stephen. The only thing he had to do was to decide
where to put the battery. When deciding to install
RESU10H next to the carport, he found that its
compact size was enough to be placed in any
cramped condition at ordinary Australian homes.
Another advantage of RESU10H was its sleek design.
"Not an industrial look, but more like a big grey
mobile phone battery. It was a great fit with my
house.” he said.
After Stephen had his RESU10H battery installed at
his home on an outer wall, his friends and family
were interested to find out about the battery and
cost saving benefits it provides. It is aesthetically
pleasing and a real conversation starter.Reduced Carbon Emissions and Peace of Mind“The battery can provide
renewable power to us
even when there’s no sun.”
“One of the most notable benefits of the RESU is that it is
not time-critical when we choose to use our appliances.”
The RESU10H can charge when solar energy is being
generated and discharge when needed, supplying enough
power to support essential home appliances during peak
hours. These compelling aspects provide a peace of mind
to Stephen.Energy Saving“We decided to take a
chance, and it has really
After installing LG Chem RESU10H to complement his
4kW Sunpower solar panels in addition to an inverter
and the battery management software, Stephen found
that the entire system was a game changer for his
household. It allowed him to monitor in real time the
flow of energy between the solar panels, battery, and the
grid. It also allows him to sell his excess energy on the
wholesale market to get the benefit of high spot prices.
“When I started considering energy storage, I didn’t
expect to have this outcome. I am really pleased with
how it has all come together.” Through his energy system,
he is expecting to continue to reduce energy taken from
the grid and save money.
The energy prices in Australia has been rising in recent years, and this trend is expected to stay for a while.
The LG Chem RESU is an optimal energy solution for green customers such as Stephen, who want to be part
of the solution to tackling dangerous climate change while saving money at the same time.
Jörg Erstling GermanySustainable Energy Life
Through an Energy
Efficient House Here we have a unique story of Jörg Erstling, a construction technician
and building biologist who set the goal of building an ecological, highly energy
self-sufficient home, made possible with the help of RESU10H.“The focus was on realizing
a house with a high degree
of self-sufficiency, which at
the same time represents
an economically interesting
solution from a long-term
When the state-certified construction technician
and building biologist began planning his family
home in the Allgäu 3 region of Isny in 2015, only
a thoroughly ecological wooden house made of
recyclable materials was considered.
With these parameters, Jörg Erstling planned
and built the house with a specialist provider of
ecological houses, Baufritz. This house is made up
of two residential units spread over three floors
with a total of 240 square metres of living space,
garage and granny flat in a hillside location.
Jörg ErstlingReliable Choice with Extensive Know-How
To achieve his self-sufficiency goals, Erstling
hired a reliable installation company with
plentiful experience that could respond quickly
if problems arise.
After intensive meetings and consultations
on high-quality components from skilled
manufacturers, he chose the LG Chem RESU10H
with professional installation and warranty
contracts, a system that ensures years of
smooth operation.Compact Size and Easy Installation“The design of the RESU10H with its shallow
depth fits into the room in a space-saving way”
The storage system has a useable capacity of approximately 9.3 kWh. The specially designed technical
and utility room in the basement of the house, where the RESU10H is located, is connected to the other
components via an empty conduit to accommodate the cable harness. One working day each was sufficient
for the installation of the PV modules plus energy storage system, inverter and all necessary connections.Remarkable Self-Sufficiency“The remarkable result
one year after completion
and move-in: up to 90
Especially in terms of self-sufficiency, the performance
of the system in the first year after completion and
commissioning is very good. The system was installed
in December 2016 and ran just as smoothly as everyone
involved had expected. As a result, 90% self-sufficiency
was achieved in about seven months.
There is no shortage of energy-intensive appliances in
the household: washing machine, dryer, two fully
equipped kitchens and an array of entertainment and
communication technology need to be supplied with
electricity. Nevertheless, the house achieved a degree
of self-sufficiency of up to 90 percent between March
and October 2017 – 20 percent more than originally
planned. The fact that this value is difficult to achieve
in the winter months can easily be explained by the
fact that part of the energy is diverted to the heat
pump, while frequent snowfalls affect the efficiency
of the solar modules.Economical Battery Solution for Home“I am pleased that I can wholeheartedly
recommend the LG Chem RESU”
Jörg Erstling's assessment is entirely positive: “A project
like this one is originally designed to deliver its benefits in
the long term. Nonetheless, even after this short time the
holistically conceived energy infrastructure has already
proven that we have decided on the correct solution.”
No further investment is required for the coming years.
In addition, the construction engineer is planning to pass
on his personal knowledge of the potential of the LG
Chem RESU Batteries.
“I am professionally active in consulting building owners.
Based on my own experience, I am pleased that I can
wholeheartedly recommend the LG Chem RESU to them.”
