Australian flow battery producer Redflow has won an order to supply five of their zinc-bromine units to provide standby energy storage for remote telecoms towers in South Africa.
The sale was made through Redflow’s long-term South African partner, Specialized Solar Systems (SSS), which Redflow said it has worked with to enable its batteries to serve as standby power systems (SPS).
In SPS mode, charged Redflow batteries “are placed in a dormant state— with no self-discharge— until their energy is required, at which point the battery boots up to full operational status, the company said. “These batteries operate in a similar time frame to a standby generator, but with no internal combustion engine and therefore no on-site fuel storage.”
Redflow CEO Tim Harris (pictured) said the SPS system “will help open the door for access to other cellphone network operators in Africa and internationally”.
Harris said the “size of the contract is not financially material… but a pleasing external validation of demand for our batteries from the telecommunications market”
Earlier this year, Redflow raised funds through new investors and previously existing shareholders to scale up its manufacturing capacity in Thailand.
