EP Cube Gains Traction Across Global Residential Energy Storage Markets
Eternalplanet’s flagship product, the EP Cube residential energy storage system, has continued to demonstrate strong commercial traction while expanding its global footprint.
Since entering mass production in 2022, EP Cube has been launched in more than ten countries and regions, including the United States, Japan, Italy, the United Kingdom, and Germany.
In Italy and Japan, two highly competitive residential energy storage markets, EP Cube has emerged as one of the faster-growing brands in recent years. Following its market launches in the two countries in 2023 and 2024, respectively, EP Cube reached an approximately 5% market share in each market in 2025.
New Financing to Support the Next Stage of Growth
The new funding will support Eternalplanet’s next phase of development across three key areas: next-generation product R&D, global market expansion, and supply chain optimization.
The company also plans to increase investment in its AI-powered energy management platform, overseas sales and distribution channels, and localized after-sales service teams.
“Residential solar-plus-storage markets around the world are shifting from subsidy-driven growth toward value-driven growth. Product innovation will remain at the core of our competitive strategy. We will continue to pursue full-stack in-house R&D and deepen our presence in key overseas markets, including the United States, Japan and Europe. Through strong product capabilities and localized operations, our goal is to establish EP Cube as a trusted home energy system brand recognized by customers worldwide,” said Yin Shaowen, Founder and General Manager of Eternalplanet.
“As solar and energy storage become increasingly integrated, storage is emerging as a new engine of growth. Eternalplanet is focused on global markets and high-value-added businesses. We take a long-term approach, relying on strong products to navigate industry cycles while creating and sharing long-term value with our customers, employees, suppliers and investors,” said Zhuang Yan, Chairman of Eternalplanet.
