Canadian Solar EP Cube Energy Storage System - All-In-One Solar Backup Power
⚡ Before You Buy
Complete inverter + battery bundle — still requires a licensed installer, permit, and interconnection agreement. Solar panels are not included. Confirm your panel array is compatible before ordering.
The EP Cube is Canadian Solar's all-in-one solar storage system — hybrid inverter and modular battery in a single integrated unit. The modular battery design means you can start with 9.9kWh and expand to 19.9kWh by adding battery modules later, without replacing the inverter. Output is 7.6kW continuous, with the dual-inverter configuration available for 15.2kW in larger homes.
The EP Cube is designed for grid-tied homes that want backup capability without the complexity of separate inverter and battery selection. Everything is pre-engineered to work together — communication protocols, safety systems, and the monitoring app are all native. What you still need: solar panels, racking, a licensed installer, a permit, and a utility interconnection agreement.
Use our Build Your System guide to size your battery capacity, confirm your solar panel compatibility, and understand what the installer process looks like before ordering.

Do solar panels come with the EP Cube?
No — the EP Cube is an inverter + battery system only. Solar panels must be purchased separately and sized to match your inverter's PV input capacity. Use Build Your System to size your full setup.
Can I add more battery capacity later?
Yes — the EP Cube uses a modular battery design. You can start with 9.9kWh (3 modules) and expand up to 19.9kWh (6 modules) by adding battery modules later without replacing the inverter.
Can I power my home during a grid outage?
Yes, with whole-home or selected-circuit backup — the EP Cube includes automatic transfer capability. How long it lasts during an outage depends on battery capacity selected and your home's load. Size your battery to cover your critical loads.
