ZCell is the unique zinc-bromine flow battery designed for your home or office.

Australian-designed. Battery redefined

The Australian-designed ZCell is an energy storage system built around Redflow’s unique zinc-bromine flow battery, which redefines your understanding of how a battery works.

Use 100% daily. In a fraction of the space

ZCell is a scalable 10 kilowatt-hour (kWh) zinc-bromine flow battery that can deliver 100 per cent depth of discharge each day for its warranted 10 years. ZCell comes in an attractive, outdoor enclosure.

Use your solar. Lower your bills

A ZCell-based energy storage system cuts your power costs by letting you use your solar energy when you need it, rather than selling excess solar power to the grid cheap and buying it back high.

Energy independence. Go off grid

ZCell provides the perfect energy storage solution for remote properties. Rather than pay a high price to join the power grid, buy a robust ZCell-based energy system integrated with solar panels for a fraction of that cost. Use your own stored solar-generated energy and pay no power bills – ever!

Power on. Through blackouts

ZCell gives you energy independence and keeps your lights on during grid blackouts. A ZCell energy storage system can keep your business running when your competitors are paralysed by power cuts.

10 kWh capacity. From Day One to Year 10

ZCell delivers 10 kWh of sustained energy storage every day, fully backed by Redflow’s 10-year warranty. ZCell’s zinc-bromine flow battery means no loss of storage capacity – for a decade!

Environmentally friendly. Fully recyclable

The ZCell zinc-bromine flow battery is made from easily recycled or reused components. At its end of life, the battery’s zinc bromide electrolyte solution can be purified and used for new batteries. ZCell also helps to reduce carbon emissions. “With Redflow ZCell batteries and Tindo Solar panels, we can seriously reduce our carbon emissions,” said Craig Wilkins, CEO of Conservation SA.

Safe energy storage. For your home or office

Redflow’s zinc-bromine flow batteries are intrinsically safe devices. These temperature-tolerant zinc-bromine flow batteries contain an inherently non-flammable electrolyte solution, with a design that means there’s no chance of ‘thermal runaway’ – unlike legacy batteries. “ZCell can cope with a high heat environment, which is not true of a lot of batteries,” said Google Engineering Director ANZ Alan Noble, an early ZCell customer.

Redflow. Redefines the battery

Redflow’s ZCell zinc-bromine flow battery redefines your understanding of how a battery works. With 100 per cent depth of discharge daily, the ZCell delivers a sustained 10kWh of energy storage capacity throughout its operating life.
