• Max. 1C charge/discharge rate, suitable for VPP multi-scenario applications to maximize user benefits.
• AI-powered dynamic trading mode, 6CT/3CT meter with self-adaptive phase sequence, VPP integration, 5s power scheduling, and one-click APP upgrade.
• Up to 89.6% round-trip efficiency, maximizing revenue and shortening payback period.
• Ultra-High Energy Density: The highest energy density for residential energy storage systems worldwide. Stackable installation in only 3 minutes, significantly lowering labor costs.

Notably, this innovative product received the Top Innovation Award 2026 from EUPD, further cementing the company’s excellence in energy storage technology.

Expanding Horizons in Benelux

The Dutch solar energy market is undergoing a significant transformation. Over the past decade, the Netherlands has installed millions of photovoltaic (PV) systems, and battery storage is emerging as a key trend in response to the planned phaseout of the 'salderingsregeling,' or net metering scheme, set for implementation in 2027. This shift reflects a growing emphasis on energy independence and grid flexibility, with battery systems playing a pivotal role in enhancing the self-consumption of generated solar energy.

In Australia, a market characterized by a similar solar landscape, Fox ESS has rapidly ascended to become the leading residential storage brand, achieving nearly 10,000 installations monthly and peaking at almost 500 MWh in a single month. In 2025, the S&P Global Energy Residential Storage Index recognized Fox ESS as the market share leader in Europe and the UK, for the first half of the year. 

Beyond its sales, Fox ESS is committed to ongoing support, with a dedicated service team of over a hundred experts stationed across Australia, Germany, and the UK. Now, the company is poised to replicate this successful model, offering both product and service excellence to the Netherlands.

"Our product achieves an average installation of 20,000 units per month across the UK, Germany, and Australia, with an exceptionally low failure rate.

Rigorously tested in diverse environments and backed by our commitment to customer support, we are confident in our ability to ensure customer

satisfaction in the Benelux region,"  Lyren Liu, CCO of Fox ESS.
