Redflow commences first customer trial of new Gen3 battery

Redflow Limited (ASX: RFX) is pleased to announce the commencement of the first customer trial of its new Gen3 battery.    

Using two new Gen3 batteries, the trial will take place in Mount Tamborine in Queensland where Redflow already has four Gen 2 batteries supporting an off-grid energy system with end customer James Emmett.  The two new Gen 3 batteries at the Mount Tamborine site will run for a number of weeks before returning to Redflow for further analysis and testing. 

Commenting on the deployment, Redflow CEO and Managing Director Tim Harris said: “This is an important development milestone for Redflow’s Gen3 battery to become customer and production ready in 2021.  Having previously outlined our goal to commence customer trials of the Gen 3 battery by the end of 2020, we are pleased that the Gen 3 battery development and program is on track.  There is no substitute for real-life customer testing and this trial will be very valuable to understand how the Gen3 battery performs in a live environment.” 

“With Gen3, we are confident of achieving a 30% reduction in manufacturing costs through supply chain and engineering productivity impacts.  We also believe further savings can be targeted through further production and scale benefits.  The Gen3 battery will underpin Redflow’s ability to expand into larger systems and more rapidly increase take-up of our world-leading Australian technology.”

WA stockfeed company to install 600 kWh Redflow Large Scale Battery to slash energy costs

WA stockfeed supply company Semini Custom Feeds has ordered a 60-battery Large Scale Battery (LSB) – Australia’s largest Redflow-based energy storage system – to cut its fuel and energy costs by 80 per cent.

Working with Redflow’s WA partner, TIEC Electrical, Semini Custom Feeds expects the 600 kilowatt-hours (kWh) system to cut its costs by about $120,000 per year based on current expenditure on diesel, maintenance and mains power.

The Redflow LSB is a powerful integrated system for deploying as many as 60 Redflow zinc-bromine flow batteries in large energy storage systems, delivering as much as 600kWh of energy storage capacity and comprehensive redundancy capabilities.

Once the Redflow LSB and 400 kilowatts-peak (kWp) photovoltaic (PV) solar panel system is deployed, the family-owned business, located at Cowaramup, 260km south-east of Perth, near Margaret River, will also eliminate its need to buy electricity from the grid. The design aims to mitigate 80 per cent of the diesel and servicing costs and all costs for grid-connected services.

The Semini Custom Feeds order is the latest success for TIEC Electrical and Redflow in the WA agricultural sector. Last year, TIEC installed Redflow batteries at multiple rural sites including a WA orchard that has beaten bushfire blackouts and a rural “dream home” that has saved more than $100,000 by not connecting to the electricity grid.

South Africa’s Harvest SA magazine reports how Redflow batteries beat bushfire blackouts for WA orchard

South African agricultural sector magazine Harvest SA has just published a story about how an off-grid orchard in WA is using Redflow batteries to beat bushfire power blackouts.

After losing power as the night horizon glowed orange with bushfires last summer, WA orchardists Jeff and Kerry Murray installed Redflow batteries to take their Kalyakool property off-grid and make it energy-independent year-round.

Bosco director Philip Verheul

Video: Engineering News South Africa reports how Redflow batteries help PCB maker Bosco avoid power outages

Engineering News South Africa has published a video story about how Johannesburg-based printed circuit board (PCB) manufacturer Bosco is using a Redflow battery energy storage system with rooftop solar PV to avoid disruptions caused by power outages that are common in South Africa.

Engineering News reports that the company’s main competitive advantage over duty-free imported PCBs is its ability to serve its local clients quickly and accurately. 

Bosco director Philip Verheul said that meant Bosco must prevent disruptions to engage with its clients, provide quotes and ensure its engineering and design department continued to operate. Our 1 200 solar panels – supported by networked inverters – provide about one-quarter of our energy requirements during the day,” he said. 

“This is connected to the BMS, which automatically recharges the Redflow batteries or dispatches battery energy when needed, including in the event of a power outage.”

Redflow Chief Technology Officer (CTO) Steve Hickey

New Redflow CTO Steve Hickey outlines benefits of zinc-bromine batteries in Calibre Group video

Redflow’s new Chief Technology Officer (CTO) Steve Hickey explains the benefits of the company’s zinc-bromine flow batteries in a recent video published by Sydney-based Calibre Group.

North Sydney-based Calibre https://www.calibregroup.com/ is a trusted partner within the resources, urban development, technologies, defence, transport and infrastructure markets.

Mr Hickey, who previously worked as an engineer for Redflow from 2008 to 2013, explains that Redflow’s batteries are the smallest modular flow batteries in production in the world. “They are particularly suited to renewable integration, and that’s because it can be operated at full capacity and down again without degradation,” he said.

In the following video, Mr Hickey and Calibre’s Principal Engineer Pradeep Pejavar explain the benefits of battery storage, especially Redflow’s innovative modular zinc-bromine flow batteries.

John Lindsay

Former telco exec praises the benefits of Redflow’s BMS for telecom companies

Former senior telecommunication executive John Lindsay, who is a Redflow director, has recorded a YouTube video to highlight the benefits of the Redflow BMS (Battery Management System) for telecommunication companies.

Telcos, including Optus in Australia, Vodafone and RCG in New Zealand and Mobax in South Africa, have deployed Redflow’s zinc-bromine flow batteries to provide energy storage for mobile phone towers in their respective countries.

John Lindsay, who was previously CTO of major telecommunication companies including Internode and iiNet Limited, said he was “quite impressed” by the way Redflow’s BMS solved problems that he used to experience managing batteries for those ISPs.

“In a former life … I was responsible for batteries at remote telecommunication facilities and managing them was quite difficult,” he said. 

“Unlike traditional electrochemical batteries, the Redflow Zinc-Bromine Module, or ZBM, has an on-board manager that decides whether each ZBM can be charged, discharged, put to sleep or woken up. Each group of ZBMs can have a Battery Management System, or BMS, which coordinates the operations of the ZBMs and communicates with the battery charger and load with an interface called CANBUS.

“The Redflow BMS connects to a Redflow Cloud service which securely monitors the status of every ZBM and securely allows the on-board software, or firmware, to be updated, just like your computer gets updated, so you ZBM will probably be smarter in the future.

“As a former telco and ISP Chief Technology Officer, the Redflow BMS really excites me because the power systems used for mobile base station and wireless ISP sites are usually very simple – a battery charger – and the equipment is often connected directly to the batteries. Sometimes, the first time you find a lithium or lead-acid battery cell has failed is when the equipment at the site stops working.”

John Lindsay said the Redflow BMS provided real-time insight into the performance of Redflow batteries, managing them like a fleet to optimise the system’s energy storage capacity and efficiency. “The Redflow BMS turns a set of ZBMs into an energy storage appliance,” he said.

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.
