Recently, global renewable energy solutions provider FOX ESS claimed the top position nationally for installed energy storage capacity in February 2026, according to Australian solar energy consultancy SunWiz.

SunWiz’s February market report shows Fox ESS achieved the highest installed storage capacity in Australia. This milestone underlines the company’s rapid momentum across the residential storage market.

This ranking follows SunWiz’s recognition of the company earlier in the year, naming Fox ESS Top Growth Leader for 2025. The company also reported continued scale-up, reaching nearly 12,000 installations in February.

“A longstanding leader in the United Kingdom and German markets, Fox ESS has rapidly established itself as a leading force in Australia’s energy storage sector. Their competitively-priced solution and international leadership are clearly resonating with both installers and consumers, and the February results reflect their strong and growing position in the Australian market,” said Warwick Johnston, Managing Director at SunWiz.

Performance and efficiency underpin the growth

The success of FOX ESS is not limited to a single burst, it has been built from Fox ESS’s ongoing commitment to delivering high-performance products and technology worldwide. Earlier this month, Fox ESS reported achieving a new benchmark of 97 per cent energy storage system efficiency, after an assessment by HTW Berlin that described the company as one of the world’s most rigorous testing organisations.

Fox ESS has also previously ranked among the top brands in multiple markets, according to EUPD Research. Meanwhile, the latest S&P Global Energy Residential Energy Storage Index shows the company is ranked No. 1 for market share in the United Kingdom, Poland and across Europe, based on megawatt-hour shipments.

Long-term commitment in Australia

Fox ESS is pursuing a long-term strategy to support its growth in Australia, including building an expert service team made up of 30 people dedicated to helping partners resolve issues promptly.

The company has also expanded its footprint, with two offices opened in Melbourne and Sydney, with the aim to strengthen support for distributors, retailers and installers nationwide.

“We’re thrilled to achieve this tremendous milestone, and are extremely grateful to the partners who have placed their trust in Fox ESS,” said Brooks Richard, Managing Director of APAC and the Middle East at Fox ESS.

“As the market accelerates, we’re doubling down on advanced products and tailored local services to help build a more resilient energy landscape for Australian households.”
