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.

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.
