This project is the first DC-coupled solar-plus-storage hybrid project being developed in eastern Australia.
The Maryvale Solar and Energy Storage Project is expected to begin operating in Q2 2027, with an estimated annual energy production of over 520 GWh.
The project is owned by Gentari, with PCL Construction carrying out engineering, procurement and construction works.
Ingeteam's supply includes 32 Power Stations with a total of 61 central photovoltaic inverters, 488 units of 430 kW DC-DC storage converters, their hybrid power plant controllers and commissioning services for the entire system.
Ingeteam is making a significant contribution to Australia’s decarbonisation process. The company will contribute its technology to the development of the Maryvale Solar and Energy Storage Project. This is the first DC-coupled solar-plus-storage hybrid project being developed in eastern Australia.
This hybrid system will comprise 243 MWp of installed PV power co-located with a 172 MW/2.4h battery energy storage system (BESS). Combining solar power generation with energy storage means this installation will produce more than 520 GWh of clean, reliable, firm energy annually, enough to power around 82,000 Australian households and prevent the emission of nearly 412,000 tonnes of CO2.
Clean energy solutions provider Gentari, the owner of the project, has just issued ‘Notice to Proceed’, prompting PCL Construction’ Solar District (PCL Solar) to begin the Engineering, Procurement and Construction (EPC) works. This hybrid renewable energy facility, which will feature 243 MWp of photovoltaics DC-coupled with a 2.4-hour of advanced Lithium Iron Phosphate (LFP) Battery Energy Storage System (BESS) capacity, is being developed in New South Wales, Australia, and is set to come into operation in Q2 2027.
Ana Goyén, Ingeteam’s Solar PV & BESS director, said, “We are delighted to continue contributing our technology to decarbonising the energy mix of the Australian National Electricity Market”. She added that projects integrating solar and storage technology aim to balance sustainability and energy security, while offering greater potential for managing the solar resource and generating energy much more efficiently.
The photovoltaic panels will be connected to the batteries in ‘DC coupling’ mode. This means that the battery can be charged using solar power with no loss through DC to AC conversion. This allows the project to store solar energy during the day, when prices are typically lower, and discharge the batteries to utilise this electricity during evening demand peaks, when prices are usually higher. This makes the power conversion process more efficient and enabling the operating time range of the solar farm to be expanded, thus optimizing energy use by injecting the surpluses generated during the day at night.
Combining solar generation with energy storage ensures the delivery of clean electricity over a long duration, enhancing grid stability and reliability thanks to the advanced auxiliary grid services offered by PV inverters. Ingeteam’s solution combines central solar inverters with modular DC-DC storage inverters, maximising energy availability through rack-level battery management.
For this project, the company will supply 32 power stations, including a total of 61 central PV inverters and 488 units of 430 kW DC-DC storage converters. Ingeteam will also provide its hybrid plant controller, which will manage the operation of the almost 400,000 PV panels and the 122 battery containers distributed across the site in a decentralised manner. The project will have a maximum export capacity of 172 MW into Australia’s National Electricity Market, and a maximum import capacity of 91 MW.
The Maryvale Solar and Energy Storage project has won a Long-Term Energy Storage Agreement (LTESA) from AEMO Services, acting as the NSW Consumer Trustee, in their fourth tender. This achievement highlights the importance of the project in supporting Australia’s transition to a clean electricity grid.
Ingeteam has been present in Australia for 12 years, during which time it has supplied over 4 GW and over 40 projects of solar PV / BESS projects to the country.
