New Compatibility Partner: EP Cube by Canadian Solar

EP Cube is an intelligent, flexible and reliable all-in-one home energy storage and management solution. Since its launch in 2022, EP Cube has expanded to markets across Europe, APAC and North America. Developed by Eternalplanet, an independent subsidiary of Canadian Solar Inc., EP Cube is backed by Canadian Solar's 25 years of industry track record. For homeowners across Germany, Austria and Switzerland, EP Cube combines intelligent energy management with a modular and flexible system design. With scalable battery storage, backup capabilities and a 15-year warranty, the system is designed for long-term reliability while helping households increase solar self-consumption and reduce reliance on the grid.

Compatibility with my-PV

With the new compatibility, the AC•THOR, AC•THOR 9s and AC ELWA 2 can be connected to the EP Cube. Communication takes place via Modbus TCP, and no additional metering hardware is required – keeping installation simple and cost-effective.

The EP Cube records generation, consumption and battery charging, while the my-PV device reads the available PV surplus and uses it continuously for hot water or heating instead of feeding it into the grid. Especially for homes in the DACH region, this brings electricity storage and PV-powered heating together in one smart energy ecosystem. Solar energy can be intelligently used across the home, increasing self-consumption, reducing grid consumption and supporting greater energy independence. During sunny months the primary heating system can often remain switched off. All approved system configurations, as well as the installation and configuration guide, can be found here.
