en.Wedoany.com Reported - July 12, 2026, Canadian Solar has introduced two new versions of its EP Cube series energy storage products: the Single-Phase 2.0 system and the Three-Phase Pro system. This product line is an integrated residential energy storage solution that combines a hybrid bidirectional inverter with modular lithium iron phosphate (LFP) battery technology.
Unlike common solutions on the market equipped with two maximum power point trackers (MPPTs), the Single-Phase 2.0 system integrates four independent MPPTs, delivering 10 kW AC and 15 kW DC output in a more compact form factor. This design offers greater design flexibility for complex roof configurations and enhances energy harvesting under shaded conditions.
The Three-Phase Pro system boosts AC output to 20 kW, suitable for large residential homes as well as commercial and industrial (C&I) projects. In this system, the backup port is built directly into the inverter, eliminating the need for a separate smart gateway. Up to five units can be paralleled to achieve 100 kW AC output, 120 kW PV input, and 200 kWh storage capacity, meeting scalable energy resilience needs.
The Single-Phase 2.0 system features a modular design, with each battery module having a nominal capacity of 5 kWh and weighing less than 42 kg. Up to eight battery units can be stacked on a single base, expanding capacity to a maximum of 40 kWh. For properties requiring higher capacity, installers can parallel two complete units to achieve a total storage capacity of 80 kWh. The integrated hybrid inverter includes 4 MPPTs, each allowing up to 18 A input current and 25 A short-circuit current, with a maximum input voltage of 600 V DC. The system supports a combined maximum PV input power of 15 kW. The inverter achieves a peak efficiency of 97.60% and a European efficiency of 97%. The inverter enclosure has an IP65 protection rating, while the battery modules achieve IP67 when stacked.
The Three-Phase Pro system starts with a capacity of 10 kWh using two modules and can be expanded to 40 kWh within a single stack footprint. For higher capacity needs, up to five units can be paralleled to achieve a system storage capacity of up to 200 kWh. The inverter accepts a maximum PV input power of 24 kW and is equipped with 4 MPPTs, each accommodating high-power modern PV modules with an operating current of up to 17 A and a short-circuit threshold of 24 A, operating within a wide DC voltage window of up to 1,000 V. The system provides a continuous three-phase output power of 20 kVA (400V AC) on the grid side, with a continuous current of up to 28.9 A per phase. The main inverter assembly has an IP65 protection rating, while the LFP battery stack has an IP67 rating.
For both products, Canadian Solar offers a 10-year warranty on the inverter and a 15-year or 6,000-cycle warranty on the LFP battery modules.
