About the Product

The Canadian Solar EP Cube Energy Storage System combines premium lithium iron phosphate battery technology with an intelligent hybrid inverter. This modular home battery system allows capacity expansion as energy needs grow. Start at 9.9 kWh per EP Cube and expand to 59.4 kWh without any heavy-duty tools.

The integrated hybrid solar inverter delivers 7.6kW AC output with four maximum power point trackers. The 10 ms switchover time keeps power flowing to sensitive electronics during grid outages, while advanced energy management enables time-of-use optimization and storm-alert backup modes. Also, the system also supports EV charging integration, allowing you to prioritize solar-generated power to charge your electric vehicle.

Built for extreme North American climates, the NEMA 4X aluminum enclosure tolerates ambient temperatures from -40°F to 122°F, suitable for garage, basement, or outdoor wall mounting. Furthermore, the Canadian Solar EP Cube Energy Storage System meets UL 1741-SB, IEEE 1547, UL 9540A, and UN 38.3 safety standards.

With 6,000 cycles at 80% depth of discharge, the EP Cube delivers over a decade of reliable grid-tie battery system performance backed by a comprehensive 10-year warranty covering batteries, inverter, and Smart Gateway. Furthermore, it qualifies for the federal solar tax credit, currently at 30%, when installed as part of a solar-plus-storage system.
