The EP Cube will be officially presented in Europe at the Genera exhibition in Madrid, Spain, on February 21-23, 2023. The EP Cube will allow users to increase the efficiency of their self-consumption solar PV installations by storing, managing and using the electricity generated with their own PV system. EP Cube is a flexible and smart solution that optimizes costs and reduces users' reliance on the electrical grid, at a time of elevated electricity prices.

Canadian Solar Inc. (the "Company" or "Canadian Solar") (NASDAQ: CSIQ) today announced that its majority-owned subsidiary CSI Solar Co., Ltd. ("CSI Solar") will launch the EP Cube in Europe, following the successful launch in North America in September 2022. The EP Cube is an all-in-one energy storage solution for residential applications, which will enable greater adoption and improved economics in combination with residential solar photovoltaic systems.

The EP Cube will be officially presented in Europe at the Genera exhibition in Madrid, Spain, on February 21-23, 2023.

EP Cube is a flexible and smart solution that optimizes costs and reduces users' reliance on the electrical grid, at a time of elevated electricity prices.

EP Cube is developed and produced by Eternalplanet, a consumer-oriented independent brand of energy technology under Canadian Solar's CSI Solar subsidiary.

The EP Cube integrates a hybrid inverter with stackable storage modules, while simultaneously absorbing communication cables and wires together in a stacked-up module design. It works with both new and already existing AC and DC-coupled PV systems. EP Cube is scalable and customizable from 6.6 kWh to 19.9 kWh capacities and compatible with most existing PV systems, micro-inverters, and EV chargers, making it a versatile solution. It can be installed both indoors and outdoors thanks to its IP65 rating, making the system resistant to dust and humidity.

The EP Cube is easy to transport and install - given its small size of 24.3 cm in thickness and light weight of 35 kg per battery module - which translates into shorter installation time and cost reductions for both homeowners and installers. Thanks to its aesthetically sleek design, it matches and integrates beautifully with various home styles.

With the EP Cube app users can easily manage their residential storage system and control the energy production and consumption at home in real time. The system has 3 operation modes that are designed to cover a wide range of usage scenarios: Self-consumption, time of use (TOU) and backup mode. Detailed settings under each mode can be adjusted and monitored via the mobile app.

Dr. Shawn Qu, Chairman and CEO of Canadian Solar, commented, "We are excited to expand our services and enter the home energy storage market with the launch of EP Cube. In Spain and Europe more broadly, more and more users are turning to clean solar energy as part of the energy transition, and the EP Cube is the perfect storage solution for users who want to adopt a cleaner lifestyle while reducing their energy costs and ensuring access to electricity throughout the year."

Canadian Solar will be at Genera (Spain)

Genera is one of the most important events in the renewable energy industry, taking place from 21st to 23rd February 2023 in Madrid. Further information about EP Cube will be available at Canadian Solar's booth 8A18 or by joining the presentations onsite.
