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.”

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.

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.
