The customer selected the vanadium redox flow battery (VRFB), after reviewing a variety of different energy storage technologies and due to its strengths of reliability, depth of discharge, safety and longevity.
This customer requires the SPS due to the high cost of connecting to the grid and lack of reliable power in the region.
Robust piece of equipment
VSUN Energy’s director Vincent Algar said: “The requirements of an SPS suit the strengths of the VRFB perfectly.
“It is a robust piece of equipment that can be cycled repeatedly without degradation in performance.
“Its high-temperature tolerance makes it ideal for the Australian environment and being non-flammable means that there’s no risk of it causing a bushfire.
“We look forward to seeing the growth of sales of VRFBs in Australia, as new customers begin to understand the unique benefits they provide.
The battery will be provided by V-Flow Tech Pte Ltd, a VRFB manufacturer based in Singapore.
Algar said: “We are pleased to be kicking off our relationship with V-Flow with this new sale and assisting the growth of the VRFB market in the Australian and the South East Asian regions.
“The current residential battery market in Australia is focused on the deployment of short-life, short-duration technologies such as lead-acid and lithium-ion battery systems.”
Range of solutions
Algar said VSUN Energy had the capability to deploy a range of VRFB system sizes. “Smaller, more modular VRFBs are also now readily available for grid connection.
“These systems provide alternatives to new battery customers that are safer, have longer asset lives and are more environmentally friendly overall.”
The SPS will consist of a 5kW/30kWh VRFB with a maximum discharge of 7kW.
This system uses an Australian made grid-connection approved inverter from manufacturer Selectronic and will be paired with 12kW of solar PV.
An 18KVa diesel redundancy backup system completes the system.
Standalone power system design
The SPS is designed to provide the microgrid with an uninterrupted, clean and safe source of energy primarily supplied by direct and stored solar energy.
It will initially provide microgrid power supply in a single-phase design, with options for expansion to allow for increased renewable use and eventual re-design for 3 phase power supply.
VSUN Energy now offers V-Flow’s VRFBs from 5kW/30kWh in size for sale to customers in off-grid settings.
The V-Flow product can also be deployed immediately to customers within the residential and small commercial sectors.
