ADELAIDE entrepreneur Simon Hackett-backed Australian sharemarket-listed company Redflow has launched its new residential energy battery system, ZCell.

Described as a “breakthrough” system that includes a battery made from easily recyclable or reusable components, ZCell can store 10 kilowatt hours (kWh) of energy.

This will allow for use of stored solar power at night, or for peak demand periods and support off-grid systems.

“ZCell breaks many of the rules that apply to legacy batteries, making it ideal for the home market,” said Mr Hackett, Redflow’s chairman and 10 per cent shareholder.

“ZCell lets you discharge 100 per cent of its total stored energy every day, whereas other battery types can require a significant amount of their underlying storage capacity to be locked out to prevent battery damage and to extend battery life.

“ZCell is a unique flow battery that loves to be fully charged and discharged daily.”

The core of ZCell is a Redflow ZBM2 flow battery. The battery is warranted to deliver 10 kWh of stored energy each day for as long as 10 years and is primarily made of plastic, aluminium and steel, elements that are easily recycled, while its fluid electrolyte can be reused or repurposed.

The fully installed cost of just the 10 kWh ZCell-based energy storage system will start from $17,500 – $19,500 including GST. Solar panels, inverters, if needed, will be additional costs. As a comparison, one installer in Australia is offering a 4kW solar system with the 7kWh Tesla Powerwall

integrated using a Fronius hybrid inverter for around $13,990 (GST inclusive and fully installed), with added meter costs. The installed cost using a 5kW solar system is $14,990.

A Redflow spokesperson said the ZCell battery was more efficient and the overall cost would depend on customers and their requirements. Final system cost will be set by the system installer. Redflow expects

Australian residential installations to start mid year with a $1000 introductory rebate offer for eligible Redflow shareholders.

Redflow Limited is an energy storage specialist that has developed the world’s smallest flow batteries, produced in North America by Flex, one of the world’s largest manufacturing companies.
