Canadian Solar EP Cube Energy Storage System - All-In-One Solar Backup Power (SC)

Canadian Solar EP Cube — Scalable Home Battery & Hybrid Inverter (9.9 ‑ 59.4 kWh)

Unlock true energy independence with the EP Cube, Canadian Solar’s all‑in‑one, lithium‑iron‑phosphate (LiFePO₄) storage system that’s engineered for DIY simplicity, whole‑home backup, and effortless expansion. Whether you’re adding battery storage to an existing array or starting a brand‑new solar project, EP Cube delivers best‑in‑class safety, flexibility, and performance.

Why EP Cube Stands Out

• Modular & Stackable — Start at 9.9 kWh per Cube and expand to 59.4 kWh by stacking additional battery modules or Cubes as your needs grow. No forklift required; each 70 lb (32 kg) module locks in place tool‑free.

• Hybrid Inverter Built‑In — 7.6 kW (1 inverter), 15.2 kW (2), or 22.8 kW (3) split‑phase output plus dual MPPTs accept DC and AC PV input, so the system works for both new and retrofit installations.

• Ultra‑Safe LiFePO₄ Chemistry — Passed unit‑level UL 9540A thermal‑runaway testing and meets UL 1741‑SB, IEEE 1547, and UN 38.3 requirements for worry‑free operation. Integrated AFCI & rapid shutdown keep installers and firefighters safe.

• Whisper‑Quiet & Weather‑Ready — < 50 dB at 1 m and a NEMA 4X aluminum enclosure rated for ‑40 °F to 122 °F, perfect for garages, basements, or outdoor walls.

• Smart Energy Management — Time‑of‑use load shifting, storm‑alert backup mode, and full‑function EP Cube app with Wi‑Fi/LTE connectivity let you monitor and update firmware OTA from anywhere.

• EV & Generator‑Ready — Power two 50 A Level‑2 EV chargers simultaneously or auto‑start a standby generator for extended outages. 

• Industry‑Leading Warranty — 10 years / 6,000 cycles to 80 % capacity on inverter, batteries, and Smart Gateway—all backed by Canadian Solar’s global service network.

CT-Kit for System and Energy Monitoring

* Split‑phase 120/240 V; 10 ms switchover keeps lights & servers online.
** System weight scales with module count.

Perfect Fit for These Use‑Cases

1. DIY Home Backup – Replace noisy generators with silent, automatic backup that powers essentials or your whole house.

2. Time‑of‑Use Savings – Charge off‑peak, discharge during peak to slash utility bills.

3. EV Fast‑Charging – Pair with solar to deliver 100 % renewable miles.

4. Small‑Business Resilience – Keep critical loads—POS, refrigeration, servers—running through grid failures.

Fast ROI, Federal Tax Credit, & Local Incentives

EP Cube qualifies for the 30 % Federal Residential Clean Energy Credit (IRC §25D) when installed with new or existing PV. Many states and utilities offer additional rebates—or SMART, SGIP, and Demand Response payments—that can cut net cost by 40‑70 %.
