In essence, Redback’s Smart Inverter takes DC electricity generated by solar panels and changes it into 240V AC power. It can also divert excess energy to a ZCell battery for later use.
Redflow’s ZCell home battery, launched in March, is a 10 kilowatt hour (kWh) flow battery that can "timeshift" solar power from day to night, store off-peak power for peak demand periods and support off-grid systems.
Australia is transitioning to lower emission energy systems, with 20% of homes now solar equipped. Due to the popularity of home solar systems over recent years, the government plans to minimise the subsidies to solar bonus schemes, with the NSW scheme ending on 31 December. FITs will reduce by 38.8 cents per kWh to 5.2 cents per kWh, meaning home energy systems will need to be smarter and more productive to ensure peak performance – and avoid paying for grid electricity.
Redback’s solution is hosted in Microsoft’s Azure IoT Suite cloud platform, ensuring easy updates and upgrades as their technology develops. It runs on a cloud-enabled intelligent system for analytics and remote control, which monitors consumption patterns, moving the use of appliances such as pool pumps and hot water into the “solar window” so they can be optimised to maximise self-consumption of rooftop solar.
Redflow executive chairman Simon Hackett, who was closely involved with the certification process, said the Redback inverter was a smart piece of technology. “We are very pleased that two Australian leaders in the emerging energy storage sector now have their devices working together. For customers to enjoy the benefits of Redflow's innovative flow battery technology, it's really important for us to work alongside like-minded businesses such as Redback.”
Redback Technologies founder and managing director Philip Livingston said he looked forward to working with Redflow as the energy storage sector develops. “Australia is the perfect place from which to build a globally relevant energy storage sector based on local innovation, Redback Technologies is building the infrastructure for the next generation grid and partnering with Redflow provides choice to consumers and solar installers. We are going to put more money into homeowners’ pockets and create cleaner energy for our children’s future.”
