EP Cube presented its upcoming Single-Phase 2.0 and Three-Phase Pro energy storage systems
Three-Phase Pro provides 20 kW AC output and supports the parallel connection of up to 5 units
The company also highlighted smart-appliance controls, an HMI display, and integrated EV charging
EP Cube, a residential energy storage brand under Canadian Solar, presented its Single-Phase 2.0 and Three-Phase Pro energy storage systems (ESS) at Intersolar Europe 2026. The company also announced an extension of its battery warranty in Europe from 10 to 15 years.
For residential applications, the EP Cube Single-Phase 2.0 provides 10 kW AC output and supports up to 15 kW of DC input. It incorporates four independent maximum power point trackers (MPPTs), enabling PV strings installed on roof sections with different orientations or shading conditions to be managed separately.
Alongside the storage system, EP Cube highlighted its smart-home energy management capabilities. Through Home Connect and relay-based controls, the system can manage compatible household appliances and Smart Grid Ready (SG-Ready) heat pumps. These controls allow connected loads to use surplus solar electricity or operate when electricity prices fall below a user-defined threshold. Users can monitor household electricity generation, storage, and consumption through a new human-machine interface (HMI) display, which also incorporates an AI-based assistant that provides energy management recommendations through a chat interface.
The residential portfolio also includes integrated EV chargers in 11 kW three-phase and 7.4 kW single-phase versions. Users can control the chargers based on surplus solar generation, electricity tariffs, predefined schedules, and the battery’s state of charge (SoC). In its June announcement, the company said the 11 kW and 7.4 kW versions were scheduled for launch at the end of July and in Q3 2026, respectively.
For residential and commercial & industrial (C&I) applications, the Three-Phase Pro provides 20 kW AC output. According to the company, its backup port is integrated into the inverter, eliminating the need for a separate smart gateway. Up to five units can be connected in parallel, providing a combined AC output of 100 kW, PV input of up to 120 kWp, and storage capacity of up to 200 kWh.
