EP Cube 2.0 – Essential Loads – 5 kWh

The EP Cube 2.0 is a complete home energy storage system made by Canadian Solar. It stores electricity from your solar panels and keeps your home powered during outages — day or night. It combines a battery, an inverter, and a smart energy manager into one sleek system that can be installed indoors or outdoors.

Whether you already have solar panels or are starting fresh, the EP Cube 2.0 is designed to work with your home the way it is today — and grow with you over time.

Yes — that's one of its most popular features. The EP Cube 2.0 automatically switches to battery power when the grid goes down, so your lights, fridge, and other essentials keep running without any interruption.

You can set it up to back up your whole home or just the most important circuits. How long it lasts depends on how much battery you have installed and how much power your home is using — but you can always add more battery storage to extend your backup time.

The EP Cube 2.0 is a modular system, which means you can start with what fits your budget and expand later. The base system starts with 5 kWh of storage — enough to power essential appliances overnight — and you can add more battery modules as your needs or budget grow.

Starting small is a great way to reduce your upfront investment while still getting the backup protection and solar savings you want right away.

No — you can install the EP Cube 2.0 even if you don't have solar panels yet. It can charge from the grid, so you can still use it for backup power and take advantage of lower electricity rates at night.

When you're ready to add solar, the EP Cube 2.0 is fully compatible with both new solar installations and existing ones. It's a future-proof investment either way.

It depends on what you want to back up and for how long. The EP Cube 2.0 starts at 5 kWh per battery module, and a single system can hold up to 8 modules — giving you up to 40 kWh of storage. If you need even more, you can connect up to three systems together for a total of 120 kWh.

For most homes, 10–20 kWh is plenty to cover the essentials overnight. A qualified installer can help you size the system based on your specific electricity usage.

Yes, the EP Cube 2.0 uses Lithium Iron Phosphate (LiFePO₄) battery chemistry — widely considered the safest and most stable lithium battery technology available for home use. It doesn't overheat easily and has an exceptionally long lifespan compared to other battery types.

This is the same technology used in many premium home battery systems, and it's a big reason why the EP Cube 2.0 is built to last for thousands of charge cycles.

Yes. The EP Cube 2.0 connects to your home via Wi-Fi, Ethernet, or cellular (LTE/4G), and you can monitor your energy use, battery level, and solar production in real time through the EP Cube mobile app.

You can also remotely turn off non-essential appliances during an outage to make your battery last longer — right from your phone, no matter where you are.

Yes to both. The EP Cube 2.0 has dedicated connection ports for a fuel generator (up to 19.2 kW) and a Level 2 EV charger (up to 19.2 kW). This means during extended outages, a generator can recharge your battery and keep everything running indefinitely.

It's a smart, all-in-one energy hub for your home — not just a battery.

We currently offer the following EP Cube 2.0 residential solar + battery systems:

• 4.5 kW Solar + 5 kWh Battery — Essential Loads
• 9 kW Solar + 10 kWh Battery — Essential Loads Plus
• 13.5 kW Solar + 20 kWh Battery — Normal Daily Use
• 18 kW Solar + 40 kWh Battery — Large Appliance Use

System recommendations are based on typical residential electricity usage in Canada. Actual energy requirements vary depending on household size, electrical loads, and energy usage.

Yes — it's built to handle outdoor conditions. The EP Cube 2.0 has a NEMA 4X-rated enclosure, which protects it from dust and rain. That said, we recommend installing it in a sheltered spot away from direct sun and rain when possible — like a garage or utility room — to maximize its lifespan.

It can also be mounted on the wall to save floor space, or set on a base if you prefer a freestanding setup.

The EP Cube 2.0 needs to be installed by a licensed solar or electrical professional — this is required both for safety and to ensure your system qualifies for any available rebates or incentives.

The good news: installation is typically straightforward for qualified installers, and the system is designed to make their job easy. Contact us today and we'll connect you with a certified installer in your area to get a quote and get started.
