VSUN Energy cracks home battery market with off-grid vanadium flow system

Vanadium flow battery specialist VSUN Energy Pty Ltd, a subsidiary of Australian Vanadium Limited, Perth, Australia, (ASX: AVL), has marked its first ever off-grid, residential sale in Australia, providing the energy storage component for a stand-alone power system for a home in regional Western Australia.

VSUN Energy, which is an offshoot of ASX listed resources outfit Australian Vanadium, said it had supplied a battery from Singapore-based manufacturer V-Flow Tech (VFT) for the W.A. stand-alone power system (SPS), which would be paired with 12kW of solar and 18KVa of diesel backup. VFT is a spin-off of the CleanTech Lab of Nanyang Technological University (NTU), Singapore, and benefits from unique IP arising from many years of intensive research at NTU.

The V-Flow vanadium redox flow battery system provided comprises a 5kW/30kWh VRFB with a maximum discharge of 7kW, which VSUN says the customer chose for its “particular strengths” of reliability, depth of discharge, safety and longevity.

MoU signals strong growth opportunities for the Australian VRFB market

Australian Vanadium has signed a non-binding memorandum of understanding (MoU) with V-Flow Tech (VFT). The MoU includes potential formal agreements in relation to sales, service and maintenance of V-Flow’s VRFBs in Australia, vanadium pentoxide off take arrangements, vanadium electrolyte manufacture and supply in Australia.

The MoU is for a term of two years with an option to renew for a further 12 months.

V-Flow’s small VRFB is now available via Australian Vanadium’s 100% owned subsidiary VSUN Energy to small commercial and residential market sectors in Australia.

Dr Avishek Kumar, CEO of V-Flow said: “Australia has great potential for small to mid-size batteries for household and remote microgrid application.”

V-Flow’s technology can operate between -10°C to +55°C without active cooling. The batteries have a lifespan of 25 years, with a stable performance guarantee.
