Chinese manufacturers surge ahead in Australia’s battery storage market

hile Australia’s battery energy storage market was historically dominated by Western suppliers such as Tesla, Fluence, Wärtsilä, and Powin, Chinese manufacturers have recently been rapidly expanding their presence Down Under, fueled by substantial supply deals.
Following the country’s key industry event, All Energy, in late October, several leading Chinese manufacturers announced cumulative battery energy storage supply agreements totaling nearly 10 GWh.
The largest of these deals was signed by Trina Storage, which entered a memorandum of understanding (MoU) with UK-based Pacific Green Energy Group to deliver up to 5 GWh of grid-scale battery energy storage systems (BESS) between 2026 and 2028.
The collaboration builds on Trina’s existing footprint in Australia, following its partnership with Pacific Green on the Limestone Coast North Energy Park Project, which features a 250 MW / 500 MWh BESS. Announced earlier this year in South Australia, the project is pivotal for Pacific Green, with an enterprise value of $460 million.
Pacific Green currently manages a global storage pipeline of 11 GWh, including 7 GWh in Australia and 4 GWh across Europe.
In other developments, EVE Energy has entered a strategic partnership with Australian energy company EVO Power. Under the agreement, EVE will supply 2.2 GWh of its large-scale energy storage products- Mr.Big and Mr.Giant – over the next five years, supporting the large-scale deployment of front-of-meter storage solutions in Australia.
Earlier this year, EVE Energy became the first company to launch and mass-produce a storage cell with a capacity of 628 Ah, which it aptly named Mr.Big. Its Mr.Giant system – a simplified 5 MWh DC container solution integrating Mr.Big cells – was deployed in a 400 MWh independent energy storage project in September and has since been shipped to Australia and Europe.
In the release following All Energy, EVE confirmed that EVO Power’s initial order has already been delivered, laying a solid foundation for the full 2.2 GWh partnership.
The company also highlighted that the Mr.Giant system has obtained Australian/New Zealand standards certifications, including AS 3000, AS 3008, and AS 5139, ensuring full compliance with local technical and safety requirements.
To better serve the Australian market, EVE has initiated the establishment of an Australian subsidiary, which will provide end-to-end services – including sales, pre-sales support, and local after-sales partnerships. The company’s Malaysia production base is expected to be fully operational by Q1 2026, further strengthening supply capacity for the Australian market.
At All Energy 2025, Chinese inverter and energy storage specialist Sungrow signed deals with three Australian energy wholesale and distribution companies: Raystech Group, Supply Partners, and Tradezone.
Under the agreement with Raystech, Sungrow will supply 1 GWh of BESS in 2026, including 600 MWh for residential, 150 MWh for commercial and industrial (C&I), and 250 MWh for utility-scale projects, alongside an 800 MW solar inverter deal.
With Supply Partners, Sungrow renewed its strategic distribution agreement for 2026, covering 300 MW of PV inverters and 300 MWh of BESS. The details of the Tradezone deal were not disclosed, described only as a “strategic partnership to deliver trusted clean energy solutions.
Meanwhile, Fox ESS has entered into a strategic partnership with Solar Juice, one of Australia’s leading renewable energy distributors, to collaborate on 1 GWh of battery storage projects. This partnership will cover the entire Australian market, with a primary focus on regions with the fastest-growing energy storage demand, including New South Wales, Victoria, and Queensland. Depending on project developments, the collaboration may expand to South Australia, Western Australia, and Tasmania, the companies said in a press release.
Central to this partnership are residential energy storage systems, involving the sale, promotion, installation, and technical support of Fox ESS’s KH, H3 Smart, and H3 PRO series inverters, along with EQ, CQ, and AIO series high-voltage batteries. Both companies will also explore opportunities in commercial energy storage solutions, electric vehicle (EV) charging, and smart energy management systems, including virtual power plant (VPP) integrations.
These deals, however, represent only the tip of the iceberg of Chinese energy storage companies’ dynamic expansion in Australia. According to statistics from the CESA Energy Storage Application Branch Industry Database, from January to October 2025, Chinese companies secured nearly 50 GWh of energy storage orders in the country.
