Ingeteam to supply DC-coupled solar+storage project in Australia

Spanish supplier Ingeteam has been selected as the technology provider for the Maryvale Solar and Energy Storage hybrid project, now under construction in Australia. According to the company, it is the first hybrid solar and battery project with direct current (DC) coupling to be developed in the eastern part of the country.

Located in New South Wales, the Maryvale facility will combine 243 MWp of photovoltaic generation with a 172 MW / 350MWh LFP battery system. The system is expected to be operational in the second quarter of 2027.

Under the contract, Ingeteam will supply 32 power stations comprising 61 central photovoltaic inverters and 488 430 kW DC-DC storage converters. The technology package also includes Ingeteam’s hybrid plant control system, which will manage nearly 400,000 solar panels and 122 battery containers spread across the site. Commissioning services for the entire system will also be provided.

While Ingeteam no longer supplies full turnkey solutions, a change implemented in 2022, their technology is compatible with 32 battery manufacturers globally. In this case in Maryvale, the battery system will be supplied by Chinese manufacturer CATL, ESS News understands.

The company explains that one of the project’s main innovations is the use of direct current coupling between solar panels and batteries, which allows solar energy to be stored during the day without conversion losses and released during times of peak demand, especially at night. “This approach significantly improves the system’s overall efficiency and operational flexibility,” Ingeteam said in a statement.

The project is being developed by Gentari, a clean energy subsidiary of Malaysia’s Petronas, and is being delivered by PCL Construction as EPC. Maryvale was also one of the successful applicants in AEMO Services’ fourth Long Term Energy Storage Agreement (LTESA) tender, positioning it as a cornerstone in Australia’s renewable grid transition.

Ingeteam has operated in the Australian market for over 12 years and has supplied technology for more than 4 GW of solar and storage capacity.
