SYDNEY, March 26, 2026 /PRNewswire/ -- Recently, Fox ESS, a leading provider of renewable energy solutions, has claimed the top position nationally for installed energy storage capacity in February, according to SunWiz, Australia's leading solar energy consultancy.
SunWiz's February market report shows Fox ESS achieving the highest installed storage capacity in Australia, a milestone that underlines the company's rapid momentum across the residential storage market.
The ranking follows further recognition earlier in this year, when SunWiz named Fox ESS Top Growth Leader for 2025. The company also reported continued scale-up, reaching nearly 12k installations in February.
"A longstanding leader in the UK 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," Warwick Johnston, Managing Director of SunWiz, said.
Performance and efficiency underpin the growth
The success isn't from a single burst. Instead, it builds on 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% energy storage system efficiency, assessed by HTW Berlin, described 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 UK, Poland and across Europe, based on MWh shipments.
Long-term commitment in Australia
Fox ESS is pursuing a long-term strategy to support its growth in Australia, including building a 30-expert service team dedicated to help partners resolve issues promptly.
The company has also expanded its footprint, with two offices opened in succession in Melbourne and Sydney, aiming to strengthen support for distributors, retailers and installers nationwide.
"We're thrilled to achieve this tremendous milestone, and extremely grateful to the partners who've placed their trust in Fox ESS," said Brooks Richard, Managing Director of APAC & 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."

Fox ESS Claims No.1 Spot in Australia for Energy Storage Installations
TOKYO, March 26, 2026 /PRNewswire/ -- At Smart Energy Week 2026, SINEXCEL showcased its latest utility-scale energy storage solutions, featuring the 1375kW PCS and StellaON 1250K/1575K PCS. Designed to accelerate the evolution of Japan's utility-scale BESS market, these high-performance systems address the increasingly stringent requirements of grid stability and multi-market participation.
Targeting Japan's Frequency Regulation Market
With Japan targeting 40%-50% renewable energy by FY2040, the 2MW/8MWh frequency regulation sector has become a critical battleground. This market demands ultra-fast responsiveness and rigorous compliance.
The 1375kW PCS has emerged as the benchmark solution through three core advantages:
- Precision & Speed: Millisecond-level response meets primary frequency control standards.

Building on six years of local expertise, SINEXCEL has successfully delivered over 50 projects across Japan, including over 10 installations powered by our 1375kW PCS.
Flexible Scalability with MV Station Configurations
Complementing the 1375kW PCS, SINEXCEL's StellaON 1250K/1575K PCS is engineered to optimize project economics, safety compliance, and grid integration.
Supporting multiple medium-voltage station configurations, the solution allows developers to scale efficiently while reducing installation complexity and lifecycle costs:
- 20ft 2.5MW~5MW MV Station
- 40ft 5.0MW / 6.25MW MV Station
- 40ft 9.45MW/ 10MW/ 12.5MW MV Station
Strengthening Local Partnerships
During the event, SINEXCEL also formalized strategic partnerships through signing ceremonies with key Japanese stakeholders, including investor AI.net, EPC NOAH, and service provider Sagacity.
