The sale was made through Redflow partner Vertiv for an energy storage solution being designed by the Auckland-based Hitech which aims to supply reliable, remote power to a number of sites in a nation in the Pacific Islands.
Redflow chief executive Simon Hackett (seen below, right with a ZCell battery), who is best known for having started the ISP Internode before selling it to iiNet, said: “This high-workload deployment in the tropics is ideal for our zinc-bromine flow batteries.
“Redflow’s ZBM2 is the world’s smallest flow battery – uniquely qualifying it to replace lead-acid batteries in remote site deployments, such as telecommunication sites.
"The ZBM2 runs natively at 48 volts DC, making it simple to install. It is also easy to deploy in scalable parallel clusters for high availability, high scale deployments at the largest sites.
“The ZBM2 excels in hot environments, such as the tropics, for applications that require high cycle depth and cycle frequency, as in the deployment Hitech is planning.
"This sort of environment and application cycle kills lead-acid batteries in fairly short order, requiring their frequent replacement, whereas our batteries thrive on heat and hard work.”
Hitech Solutions chief operations officer Derek Gaeth said: “Redflow’s zinc-bromine flow batteries were our best choice because they meet the needs of this project.
“ZBM2 batteries are well suited to managing hybrid power, have a good charge/discharge profile and have a high tolerance of temperature variance, especially heat, which is important in the tropics.”
