TECHNOLOGY — HOME ENERGY STORAGE
Storage That Grows With You
EP Cube is a modular home battery system from the Canadian Solar family, built in 5 kWh increments so your system can begin exactly where your needs are today and expand as your home, your vehicles and your ambitions grow.
Few homes need the same storage on day one that they will need in ten years. EP Cube is engineered for that reality.
Each 5 kWh lithium iron phosphate battery module stacks onto a common base beneath a hybrid inverter, so a system can begin at 5 kWh and grow to 40 kWh in a single stack, or to 120 kWh with three systems working in parallel.
We size your first stage around how you live today and engineer the electrical infrastructure for where you are going, so adding capacity later is a simple addition rather than a redesign.

What This Buys You
Engineered for life in Ontario
Ready before the storm
EP Cube watches the forecast. When severe weather is on its way, it charges itself to full in advance, and if the grid goes down, your home transfers to stored power automatically.
Power for the loads that matter
With 11.5 kW of continuous output and the surge capacity to start motors, a properly designed EP Cube system can carry well pumps, heat pumps, air conditioning, and EV charging, not just the lights.
Generator-ready
For rural properties with a standby generator, EP Cube takes charge of it intelligently, charging from the generator efficiently and sparing you hours of idling and the drone of a generator running through the night.
Intelligence
A system that thinks ahead
Rate-aware savings
EP Cube stores your surplus solar for the evening, and can top up from the grid overnight under Ontario’s time-of-use and Ultra-Low Overnight rate plans, then draw on stored energy when prices peak.
Automatic load control
Set rules once and let the system manage itself: pause high-demand appliances when stored energy runs low, and run discretionary loads when the battery is full.
Works with what you have
AC coupling adds storage to an existing solar array and third-party inverters, while DC coupling connects new panels directly to the EP Cube for maximum efficiency.

Canadian roots
EP Cube comes from the Canadian Solar family. Canadian Solar was founded in Guelph in 2001, the same city Bluewater calls home, and has grown into one of the world’s largest solar manufacturers.
Safety by design
A NEMA 4X enclosure, LFP chemistry and testing to the UL 9540A thermal runaway standard, in a system that mounts on the floor or the wall.
Monitoring in your hand
The EP Cube app shows production, storage and consumption in real time, and puts every setting, schedule, and automation at your fingertips, wherever you are.
