Canadian Solar EP Cube 2.0 5.12kWh Battery Module

The Canadian Solar EP Cube 2.0 batteries are a modular, scalable home energy storage solution built for reliable backup power, higher solar self-consumption, and daily load shifting. Start with the EP Cube 2.0 all-in-one system and add battery modules over time as your needs grow. EP Cube battery storage scales from 5.0 kWh up to 20.0 kWh on a single base, and can be expanded further to 25.0 kWh, 30.0 kWh, 35.0 kWh, and 40.0 kWh using a double-base setup—ideal for homeowners who want longer runtime, greater outage protection, and more flexibility as energy usage increases.

EP Cube batteries are engineered for split-phase 240V and 208V residential applications and deliver strong, usable continuous power. Battery-only charging performance scales with capacity and reaches up to 6kW continuous on larger configurations. Discharge performance increases as storage grows, delivering up to 11.5kW continuous battery-only discharge at 240V (48A) or 9.9kW at 208V (48A) on larger system sizes—supporting more essential loads during outages (when properly designed and installed). Paired with solar panels like the Canadian Solar 680W bifacial panel, EP Cube supports up to 11.5kW (240V) / 9.9kW (208V) continuous discharge during full sun. Larger configurations also list 185A LRA (1s), supporting short-duration motor starting demands where applicable.
