Redflow Limited, a publicly-listed Australian company (ASX: RFX), produces small 10kWh zinc-bromine flow batteries that tolerate daily hard work in harsh conditions. Marketed as ZCell and ZBM2, Redflow batteries are designed for high cycle-rate, long time-base stationary energy storage applications in the residential, commercial & industrial and telecommunications sectors, and are scalable from a single battery installation through to grid-scale deployments. Redflow batteries are sold, installed and maintained by an international network of energy system integrators. Redflow’s smart, self-protecting batteries offer unique advantages including secure remote management, 100 per cent daily depth of discharge, tolerance of high ambient temperatures, a simple recycling path, no propensity for thermal runaway and sustained energy delivery throughout their operating life.


Alan Noble with his ZCellsAustralian battery company Redflow Limited (ASX:RFX) today announces that a residential energy system at an off-grid property in SA is the first completed customer deployment of its ZCell batteries.

Previously mains power was available in only one corner of the hilly 100-hectare Willunga property, owned by the family of Alan Noble, Engineering Director for Google Australia and New Zealand.

Mr Noble said extending mains power further across the hilly terrain would be substantially more expensive and less flexible than the off-grid solution with two ZCell batteries, which can store 20 kilowatt hours (kWh) of energy, powered by solar panels on the roof of a large implement shed.

The batteries, which were integrated with 24 Australian-made Tindo Solar panels and two Victron battery inverters by ZCell installer Off-Grid Energy Australia, continued working uninterrupted during the recent storm-caused power failure that blacked out the rest of South Australia.

Mr Noble said he had installed the ZCells to provide him with flexibility, safety and affordability. “We wanted the flexibility to build anywhere on the site without having overhead power lines,” he said.

Australian battery company Redflow Limited has received a major order for 48 ZCell batteries, worth about $600,000, from Melbourne-based energy system installer Standard Solar.

Standard Solar, which supports clients nationally from its head office at Seaford, Victoria, was one of the first seven ZCell installation companies announced by Redflow last week. Redflow will start delivering the first batteries for this order during the next two weeks.

Now available in Australia,ZCell is a 10 kilowatt hour (kWh) zinc-bromine flow battery that can ‘timeshift’ solar power from day to night, store off-peak power for peak demand periods and support off-grid systems. Redflow received its first shipment of batteries for ZCell in Australia this month.

Standard Solar Chief Technology Officer James Graham said his company had already sold about half the ZCells from this initial order. “We have sold ZCells to customers ranging from a government agency and an educational institution to businesses and home users,” he said.

Simon HackettAustralian battery company Redflow Limited today announces the first approved installers for its new ZCell energy storage solution, with companies providing specialist local and national coverage.

After yesterday announcing the arrival in Australia of its first shipment of batteries for ZCell-based energy storage systems, ASX-listed Redflow has revealed the initial five companies approved to offer ZCell throughout Australia. Redflow has conducted installer training sessions for a number of additional companies, with further listings to be added at as they are approved.

The first ZCell installers are Off-Grid Energy Australia (SA, VIC, ACT, NSW, TAS and southeast QLD.), Standard Solar (national), Suntrix (SA, VIC, NSW, QLD), The Solar Depot (SA, NSW) and WES Group (QLD, NT, WA).

Redflow CEO Simon Hackett said each company, which already had the in-house expertise and experience necessary to install energy storage systems, was now approved to install ZCell. “We expect to announce more installers in coming weeks,” he said.
