The Australian company Redflow is accepting pre-orders for its new home energy storage system, the ZCell battery. It has a 10 kilowatt-hour usable storage capacity, can provide 3 kilowatts of continuous power, and is suitable for on-grid and off-grid use. Deliveries will begin in August 2016.
While there are many lithium-ion storage systems on the market, the Redflow ZCell stands out as the only zinc bromide flow battery. Its unique chemistry gives it several advantages over lithium-ion systems. One is it can lie dormant for long periods at any level of charge without suffering from deterioration. And another is its storage capacity will never decline over its over its entire lifespan.
