battery backup that never blinks.
St. Albert Battery Backup Installation
When the grid drops, the EP Cube takes your home in under 20 milliseconds — no flicker, no fuel, no noise. One all-in price covers the battery, engineering, the City of St. Albert permit and our in-house Red Seal Master Electrician, whether you’re on a 100A panel in Grandin or adding storage to solar in Jensen Lakes.
An installed EP Cube in St. Albert costs $19,381 (9.9 kWh) to $24,723 (19.9 kWh) all-in — battery, built-in hybrid inverter, engineering, City of St. Albert permit, and Red Seal Master Electrician install. Budget ~10 kWh/day for critical loads and you get roughly 24 to 48 hours of runtime, with the automatic switchover happening in under 20 milliseconds.
Every EP Cube size, priced for St. Albert.
Four sizes, one all-in number each: the battery, the built-in hybrid inverter, all electrical work by our Master Electrician–led crew, engineering, and the City of St. Albert permit and inspection. No line items appear later.
| EP Cube size | Installed price (all-in) | Bundled with new solar (−$1,000) | Who it suits |
|---|---|---|---|
| 9.9 kWh | $19,381 | $18,381 | The essentials covered — fridge, furnace fan, sump pump, lights |
| 13.3 kWh | $21,578 | $20,578 | The essentials with a comfortable full overnight on top |
| 16.6 kWh | $22,942 | $21,942 | Bigger houses, plus storing solar for self-consumption |
| 19.9 kWh | $24,723 | $23,723 | Top of the single-unit range — two full days of critical loads |
Installing the battery alongside a new solar system is what earns the $1,000 bundle discount — battery-only retrofits don’t qualify. Because the EP Cube is built from modular 3.3 kWh packs, any unit can grow to 19.9 kWh later; under Alberta code (CEC Rule 64-918) a St. Albert home can carry two units — roughly 39.8 kWh in practice, inside the 40 kWh dwelling cap.

How long each size runs a St. Albert home.
Continuous output is identical across all four sizes — plenty to keep the fridge, freezer, furnace fan, lights, sump pump and Wi-Fi going together. What the size buys you is hours.
| Backed-up load | Draw | 9.9 kWh | 13.3 kWh | 16.6 kWh | 19.9 kWh |
|---|---|---|---|---|---|
| Fridge + freezer | 150W | ~66 hrs | ~88 hrs | ~110 hrs | ~132 hrs |
| Furnace fan | 500W | ~20 hrs | ~26 hrs | ~33 hrs | ~40 hrs |
| LED lights (10) | 100W | ~99 hrs | ~133 hrs | ~166 hrs | ~199 hrs |
| Sump pump | 800W | ~12 hrs | ~16 hrs | ~20 hrs | ~25 hrs |
| Critical loads, ~10 kWh/day* | — | ~24 hrs | ~32 hrs | ~40 hrs | ~48 hrs |
*A typical critical-load day is about 10 kWh — fridge, freezer, furnace fan, lights, sump pump, Wi-Fi and phone charging. Real-world runtime depends on usage, and with solar attached the battery tops itself up in daylight.
St. Albert’s battery question is really a panel question.
St. Albert has already had two warnings from Alberta’s grid. The first came on January 13, 2024, when the AESO declared a grid alert and an emergency alert reached every phone in the province at 6:44 p.m.; the second, on April 5, 2024, brought genuine rotating outages that shed ~244 MW of load between 8:53 and 9:16 a.m. Day to day, FortisAlberta — St. Albert’s wires utility — averages under 1.3 hours of outage per customer per year. Our honest take for St. Albert: buy a battery for seamless resilience and for soaking up your own solar, not to shrink the bill — with no residential time-of-use rates in Alberta, there’s nothing to arbitrage.
Grandin, Mission & Lacombe Park
Many of St. Albert’s mature homes run 100A services. That doesn’t rule out a battery — it means the load calculation and panel assessment have to be done properly, which is exactly what our in-house Red Seal Master Electrician does at the free site visit before we quote.
Jensen Lakes & Erin Ridge North
The newer north-end neighbourhoods are where we most often add an EP Cube to existing solar: the built-in hybrid inverter AC- or DC-couples to virtually any array, storing daytime production for evening use and keeping the house live through any outage.
What it actually protects
Sump pumps in spring melt, the furnace fan at −30°C, the deep freeze, Wi-Fi for working from home — and it does it silently, in under 20 milliseconds, with no fuel, no exhaust and no maintenance.
Four steps. Typically 4–6 weeks.
Free assessment
Your panel gets checked and a proper load calculation gets run — critical on the 100A services common in Grandin-era homes — then we review your garage and backup priorities and hand you an exact all-in price. No obligation.
Engineering + permit
We prepare the engineering package and file the electrical permit with the City of St. Albert under our licensed electrical contractor designation.
One-day install
In one working day our in-house crew hangs the EP Cube on your garage wall — attached-garage mounting is Alberta’s standard under STANDATA Variance 21-ECV-064-900-ESS — and wires up the circuits you chose to back up.
Inspection + commissioning
Once the City of St. Albert inspector signs off, we commission the system and get the EP Cube app onto your phone. From signed agreement to commissioning typically runs 4–6 weeks.
550+ installs since 2018 · in-house master electricians · no subcontractors · BBB A+ · 5.0 ★ on Google
Every St. Albert battery permit we file carries a Master Electrician’s name — because legally, that’s what a battery install is.
Alberta law is unambiguous here: putting a battery in a home calls for an electrical permit pulled by a licensed electrical contractor — not a handyman job, and not paperwork a homeowner files themselves. Stellar’s in-house Red Seal Master Electrician is named on every permit we pull, including every City of St. Albert battery permit, and the same in-house crew does the work — we do not subcontract residential installations.
That matters most in St. Albert’s older neighbourhoods, where 100A panels demand a real CEC load calculation before anyone promises you a battery. Behind the work sits $5M in liability insurance, BBB A+ accreditation, and Canadian Solar’s 10-year / 6,000-cycle warranty on the EP Cube — NEMA 4X-rated hardware, wired to code every single time.
This is how a Stellar Upgrades battery install turns out
Red Seal electricians finish every EP Cube in-house. Clean conduit, tidy panel work, no subcontractors, no shortcuts — the same crew that would work in your St. Albert garage.
Installed by our Red Seal Master Electrician and the Stellar Upgrades team — 550+ installs completed since 2018.
