EP Cube Wins Prestigious Red Dot Design Award 2025

KITCHENER, ON, July 16, 2025 /PRNewswire/ -- Canadian Solar Inc. (the "Company" or "Canadian Solar") (NASDAQ: CSIQ) today announced that its residential energy storage system, EP Cube, designed by its subsidiary, Eternalplanet, has won the prestigious Red Dot Award 2025. This award recognizes EP Cube as one of the most well-designed residential energy storage products globally. Earlier this year, EP Cube also received several other international design awards, including the iF Design Award and MUSE Design Award Gold.

The Red Dot Design Award, established in 1955 in Germany, is one of the world's most prestigious design competitions, often referred to as the "Oscars of Industrial Design." In 2025, it received over 10,000 entries from more than 60 countries, with fewer than 1.5% earning the award — making it a globally recognized mark of design excellence.

EP Cube impressed the Red Dot jury with its modular design and ultra-slim profile. Key product features include the following:

• Modular stacking design: Breaks the limitations of fixed-capacity systems, allowing flexible expansion based on user needs.
• Ultra-slim profile: Minimizes installation space and time, adapting to a variety of home installation environments.
• Three-phase output capability: Offers a maximum AC output of 12 kVa and a capacity of up to 40 kWh, enabling scalable capacity options from 5 kWh to 40 kWh to support diverse household energy profiles.
• PV system compatibility: All EP Cube systems are compatible with existing and new PV systems, helping customers reduce dependence on the grid and advancing clean energy adoption.

Susanne Pflug, Chief Commercial Officer of Canadian Solar's Home Energy Storage Business Unit, said, "Winning the Red Dot award is not only an honor, but also a validation of our mission to drive the future of green energy with innovative technology. EP Cube transforms energy storage technology into a smart home partner, setting a new paradigm between technological innovation and lifestyle aesthetics."
