Redflow ZCell

Grid Battery Storage – Redflow ZCell

ZCell is a new type of battery with performance characteristics that make it ideally suited to store energy for your home or office. The Australian-designed ZCell is an innovative flow battery that can deliver 10 kilowatt hours (kWh) of stored energy each day, harvesting energy from your solar panels or lower-cost off-peak power, for use when you need it.

About the size of an air-conditioning unit, ZCell is designed by ASX-listed company Redflow Limited (ASX:RFX), based on its core ZBM2 battery, which is operating at sites around the world including Australia, Asia, Africa, America and Europe. 

Check out this video for an explanation on how the ZCell Flow battery works, from Redflow CEO Simon Hackett.

Redflow ZCell

The Australian-designed ZCell is an innovative flow battery that can deliver 10 kilowatt hours (kWh) of stored energy each day, harvesting energy from your solar panels or lower-cost off-peak power, for use when you need it.
ZCell is a great battery choice for either AC or DC power, on-grid or off-grid storage energy systems, or a bit of both. As ZCell is a modular system, it is straightforward to connect multiple ZCells to deliver more energy storage for larger homes or businesses.
24/7 battery management allows you to use an easy web-based browser via smartphone or PC to set up, monitor, and control your ZCell. It also reports battery status and operational information that lets your AC inverter/ charger optimise use of the energy stored in your ZCell.

High Performance: 100% depth of discharge, without battery damage
Safety: Mechanical damage does not cause explosion or fire
Warranty: Retains full storage capacity for 10 yr warranted life
Monitoring: Web-based browser via smartphone or PC
Unlimited Shelf-Life: Switch off and hibernate for extended periods


Off-Grid Energy is one of the first Authorised ZCell Installers in Australia.

A ZCell system (including compatible inverters, associated equipment, and standard installation) starts at $22,590.

The Off-Grid Energy Advantage

Installing battery storage isn’t as simple as installing plain solar. Our head technician has been designing off-grid systems since 2002, and our core team has been working with battery systems since 2006.
Quality Components
It’s unwise to make compromises when you are energy independent. There is a world of difference in the quality of system components, so we make sure we only source the very best.
Expert Design
Inferior off-grid systems provide frustratingly unreliable power and a costly short system life due to poor sizing, mismatched equipment, non-compliant design, and unsafe installation. Our expert technicians ensure these pitfalls are avoided.
Happy Customers
We have hundreds of happy battery storage customers across Australia. When you ask us for a customer reference, we can provide someone with an off-grid system just like yours.
We understand the responsibility of providing reliable power, and being available 24/7 to troubleshoot. We value honesty and integrity in our staff, and always strive to exceed expectations.
