Canadian Solar EP Cube 2.0 5.12kWh Battery Module

PRE-ORDER EXPECTED late July

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 a smaller configuration and expand 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). For solar-producing conditions, 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.
