James Emmett’s house at Tamborine Mountain, south of Brisbane

Brisbane doctor builds off-grid dream house powered by solar PV and Redflow batteries

When Brisbane doctor James Emmett decided to build his dream house on Tamborine Mountain south of Brisbane, he chose Redflow batteries to make it as environmentally sustainable as possible.

In 2017, before even starting construction of the house on the 3.2 hectare former farming property, James installed two 10 kilowatt-hour (kWh) ZCell batteries to deliver power needed by builders. The system also included a Victron inverter-charger, a Fronius inverter, and 13 kWp of ground-mounted solar panels. An ultracapacitor was used to meet the power surges demanded by the builders’ larger drop saws.

When the house construction was completed a further two ZCell batteries were added to the system. Now, with the house built, he is reaping the benefits of off-grid living, with plenty of free energy to power his home as well as charge his electric car and electric zero turn mower.

Remote home near Quindanning powered by Redflow battery

Redflow battery powers off-grid WA home, avoiding $100,000-plus in costs to connect to the power grid

A single Redflow battery is powering a “dream home” near Quindanning in south-west WA, saving its owners the six-figure cost of connecting it to the electricity grid.

In 2017, Geoff and Roz transported a derelict building made up of two hexagonal pods to their rural property in the south-west of Western Australia, aiming to create their dream retirement home.

With picturesque valley views towards the little town of Quindanning, about 170km from Perth, the 80-hectare property sits high on a ridge surrounded by native bushland. But the difficult-to-access property’s location meant the six-figure sum to connect to the power grid was cost-prohibitive. Going off-grid was the obvious solution.

Redflow partner TIEC, through its RBSS (Renewable Battery Storage Solutions) division, was commissioned to design a single-battery energy storage system that could meet the couple’s immediate needs and expand when their budget allowed.

New Redflow partner predicts battery boom as WA solar tariffs end

West Australians are increasingly seeking the benefits of new-generation batteries as the State’s generous solar feed-in tariffs start to disappear, reports Redflow’s new WA partner Leith Elsegood.

WA homes that installed solar systems a decade ago are already losing the 40-cents per kilowatt-hour (KWh) feed-in tariff, introduced by the State Government to encourage the installation of solar panels. The 10-year feed-in tariff will end in 2021.

Since 1989, Mr Elsegood’s company, TIEC Services, has installed solar photovoltaic (PV) systems and energy storage systems throughout WA, at remote communities and, more recently, in high-end homes in the Perth metropolitan suburbs.

TIEC Services recently signed up as installer of new-generation Redflow energy storage batteries for Perth and WA. Already, the company has won large, residential solar and energy storage contracts with Redflow’s ZBM2 batteries. “The Redflow battery is ideal for WA conditions, handling the dry heat and the great distances in remote regions,” Mr Elsegood said.

Redflow’s Hackett: 2016 is inflexion point for battery storage

Simon Hackett, the executive chairman of Australian battery storage maker Redflow, says it is now clear that 2016 will be an inflexion point for the battery storage market in Australia, given huge interest from consumers and the rush of new products to the market, reported RenewEconomy. Redflow is preparing to release its 10kWh zinc bromine “flow” battery, known as the ZCell, into the market in August, where it will be competing with a host of new lithium-ion batteries, some of which – such as Enphase – are already reporting significantly higher than anticipated sales. Read on at RenewEconomy 

Australian Energy Storage Conference 2016

JUNE 2016: Australian energy storage specialist Redflow revealed the custom-designed enclosure for its recently launched ZCell home battery at the 2016 Australian Energy Storage Conference & Exhibition in Sydney.

The outdoor-rated enclosure, which measures around 1000mm long, 500 mm wide and 1150 mm high, holds Redflow’s unique 10 kilowatt-hours (kWh) ZBM2 flow battery,  Designed to be easy for installers to deploy, one or more ZCell units are typically installed on the ground beside an outdoor wall and connected to appropriate battery inverter/charger equipment.

Redflow Executive Chairman Simon Hackett, who spoke at an opening session of the Australian Energy Storage Conference, said the ZCell enclosure was designed and is being manufactured in Australia. “This is the first time we have shown our ZCell enclosure publicly,” he said. “We’re very pleased with the design, which is both attractive and practical, that allows straightforward outdoor installation, and features a built-in secondary containment system to protect against the unlikely event of an electrolyte fluid leak.

“We expect to receive the first production batch of ZCell enclosures for quality assurance testing before the end of June, with ZCell bundles now expected to be delivered to installers for customer deployment from August.”

 

Redflow takes on Tesla Powerwall with ZCell home battery

Redflow executive chairman Simon Hackett owns three Tesla cars but when it comes to home batteries he believes he can go one better than the Californian car maker. His company’s ZCell home battery using zinc-bromide “flow” technology performed better than the lithium-ion systems dominating the market, he told Angela Macdonald-Smith in the Sydney Morning Herald.
