Clean energy partnership to increase flow battery options

Sustainable energy storage company Redflow has announced that its batteries now successfully integrate with the Sunsynk range of hybrid inverters.

This means Australian and global integrators can offer the Sunsynk hybrid inverter to customers using Redflow’s zinc-bromine flow batteries in their energy storage solution.

The Sunsynk inverter’s capabilities include the ability to connect solar and batteries to a single- or three-phase grid-connected inverter, continue charging batteries from solar PV during a grid outage and control a backup generator if required as a small microgrid.

As a fully compliant CEC-listed, grid-connected inverter, the Sunsynk hybrid inverter provides a different option for customers using Redflow’s zinc-bromine flow batteries.

“Our aim is to give customers a choice when they are designing their energy storage solution,” said Redflow CEO and Managing Director Tim Harris. “We understand that requirements vary, and our aim is to offer a range of inverter options to ensure all their needs are met.

“The Sunsynk hybrid inverter is one such option. This inverter simplifies the way customers connect to the grid and seamlessly integrates batteries and solar, which will be particularly beneficial for off-grid (with some small additional requirements), commercial and industrial customers,” Harris said.

Sunsynk CEO Keith Gough said, “We are pleased to be working with Redflow, who is at the forefront of flow battery technology. Redflow’s successful integration testing of the Sunsynk hybrid inverter with their zinc-bromine flow batteries provides integrators and customers confidence in their choice.”

The integration testing was completed at Redflow’s Integration and Testing facility in South Australia by Redflow Battery Management System Architect Simon Hackett.

The Sunsynk 8, 10 and 12 kW three-phase hybrid inverters are fully AS4777.2:2020 certified and CEC approved for the Australian market and can integrate with solar PV arrays, 48 VDC battery storage, and grid and generator connections (including wind turbines) in a single outdoor-capable, wall-mounted solution. Up to 10 Sunsynk hybrid inverters can be connected in parallel to increase customer capacity.

Sunsynk will also be introducing larger 25, 30, 45 and 50 kW three-phase hybrid inverters into the Australian market for larger sites. When available, Redflow will undertake additional integration testing with Sunsynk to ensure compatibility with the new larger inverters.

Sunsynk inverters are currently sold in the UK, Europe, South Africa (and into Africa), Hong Kong and China and are already established in Australia.
