Redflow executive chairman Simon Hackett owns three Tesla cars but when it comes to home batteries he believes he can beat the Californian car maker and its followers.
His company's ZCell home battery using zinc-bromide "flow" technology performed better than the lithium-ion systems dominating the market, he said.
"This is one that's going to work for you in the house – the harder you work ours the happier it is," he said. "Everyone else is just taking the same sort of lithium batteries and repackaging them."
Flow technology involves storing electricity in liquid electrolytes, rather than in electrodes, as lithium-ion does. Two separate tanks of liquid are pumped past a membrane held between two electrodes, producing an electric current.
Mr Hackett said that unlike lithium-ion batteries, the ZCell flow battery lets users discharge 100 per cent of its stored energy every day and is designed to be fully charged and discharged daily, with minimal degrading. A home with a solar panel system that added a 10-kilowatt-hour ZCell system could cut its power bill by 95 per cent, he said.
