One Step Off the Grid

Australian vanadium flow battery specialist VSUN 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 for the W.A. stand-alone power system (SPS), which would be paired with 12kW of solar and 18KVa of diesel backup.

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.

The choice of battery storage technologies in support of solar energy supply is broadening to suit a variety of emerging applications. VSUN has just made its first power play for vanadium-redox-flow batteries in the off-grid residential market.

VSUN Energy, an organisation formed with the express intent of increasing awareness of the benefits of vanadium-redox flow batteries (VRFB) has taken to selling systems using the technology; its first residential case study came about because equipping a new farmhouse with a VRFB-based standalone power system was cheaper than connecting that rural home to the grid — nevermind the savings that will ensue as the farm lives through its first quarter without receiving a power bill.

The standalone power system (SPS) tailored for this property consists of 12 kW of solar PV, a 5 kW/30 kWh VRFB with a maximum discharge of 7 kW; an Australian-made Selectronic inverter and an 18 KVa diesel redundancy back-up system. The SPS is designed to provide an uninterrupted, clean, safe source of energy, primarily generated by direct and stored solar energy.

Special Report: Australian Vanadium has hit a milestone with its wholly-owned subsidiary VSUN Energy selling the first standalone vanadium flow battery system to a residential customer.

The customer in regional Western Australia acquired the standalone power system (SPS) due to the high cost of connecting to the grid and lack of reliable power in the region.

Australian Vanadium (ASX:AVL) added that the vanadium redox flow battery (VRFB) system was selected due to its particular strengths of reliability, depth of discharge, safety and longevity.

The VRFB was provided by Singapore-based manufacturer V-Flow Tech.
