Battery Backup for
Sherwood Park homes.
Sherwood Park Battery Backup Installation
The EP Cube takes over your home in under 20 milliseconds when the grid drops — silently, automatically, with no fuel. Installed by our in-house Red Seal Master Electrician, with the Strathcona County permit and inspection included. Sized for the Park's bigger two-storey homes and nearby acreages.
What battery backup costs in Sherwood Park.
An installed EP Cube battery backup in Sherwood Park costs $19,381 (9.9 kWh) to $24,723 (19.9 kWh) all-in — battery, hybrid inverter, Master Electrician install, engineering, and the Strathcona County permit and inspection. Plan on roughly 10 kWh per day of critical loads and you get 24 to 48 hours of runtime, with automatic switchover in under 20 milliseconds.
Every EP Cube size, priced all-in for Sherwood Park.
Same fixed pricing in the Park as everywhere we install. Every price below includes the EP Cube battery, its built-in hybrid inverter, installation by our Master Electrician–led crew, engineering, and the Strathcona County electrical permit and inspection. No trip charge, no hidden line items.
| EP Cube 1.0 size | Typical fit in Sherwood Park | Runtime @ ~10 kWh/day critical loads | Installed price (all-in) |
|---|---|---|---|
| 9.9 kWh | Essentials: fridge, freezer, furnace fan, lights, Wi-Fi | ~24 hours | $19,381 |
| 13.3 kWh | Essentials plus sump pump and extra margin | ~32 hours | $21,578 |
| 16.6 kWh | Larger two-storey homes in Emerald Hills, Summerwood | ~40 hours | $22,942 |
| 19.9 kWh | Whole-home priority loads, acreages, solar pairing | ~48 hours | $24,723 |
Take $1,000 off any size when the battery is bundled with a new solar install (the bundle discount does not apply to battery-only retrofits). Because every EP Cube is built from 3.3 kWh modules, the unit you buy today can grow later — right up to 19.9 kWh. Ask about the new EP Cube 2.0 (5–40 kWh modular), quoted on consultation pricing. Alberta has zero battery rebates in 2026, and anyone claiming otherwise is guessing. See the full pricing breakdown →

How long each size carries a Park home.
Continuous output is identical across all four sizes at 7.6 kW — plenty to keep the fridge, freezer, furnace fan, lights, sump pump and Wi-Fi going at once. What capacity changes is how long they keep going.
| What you're powering | Draw | 9.9 kWh | 13.3 kWh | 16.6 kWh | 19.9 kWh |
|---|---|---|---|---|---|
| Fridge + freezer only | 150W | ~66 hrs | ~88 hrs | ~110 hrs | ~132 hrs |
| Furnace fan | 500W | ~20 hrs | ~26 hrs | ~33 hrs | ~40 hrs |
| Critical loads bundle* | ~10 kWh/day | ~24 hrs | ~32 hrs | ~40 hrs | ~48 hrs |
*The critical-loads bundle assumes a fridge, freezer, furnace fan, lights, sump pump, Wi-Fi and phone charging all drawing at once. Actual runtime varies with usage. Add rooftop solar and the battery refills every day — effectively stretching outage coverage indefinitely.
Why Sherwood Park homes are adding battery backup.
Alberta's grid has already rehearsed the argument. The evening of January 13, 2024 brought an AESO grid alert, and at 6:44 p.m. a province-wide emergency alert reached every phone in the Park asking Albertans to cut usage immediately. April 5, 2024 went a step further: real rotating outages, roughly 244 MW of firm load shed between 8:53 and 9:16 a.m. Day to day, FortisAlberta customers — that's the Park's wires utility — average under 1.3 hours of outage a year. Short and rare, but always unannounced.
Bigger homes, bigger reserve
Strathcona County homes run larger than the Alberta average — two-storey layouts in Emerald Hills, Summerwood and Lakeland Ridge, plus nearby acreages with wells and shops. Higher daily loads push most Park installs toward the 16.6 and 19.9 kWh sizes, and CEC Rule 64-918 allows up to two units (~39.8 kWh) per dwelling.
Strathcona County permit
Battery permits in Sherwood Park go through Strathcona County, not the City of Edmonton. Our in-house Red Seal Master Electrician pulls the permit and the County inspection is coordinated for you — both included in the installed price.
Honest Alberta math
With no residential time-of-use rates in Alberta, a Sherwood Park battery buys you resilience plus solar self-consumption — not rate arbitrage. A battery on its own doesn't lower an Alberta power bill, and we won't pretend it does. What it does is keep the furnace fan, sump pump and fridge running when the grid can't.
“Our solar was installed four years ago by a different company. When we asked them about adding battery backup, they said they couldn’t figure out the integration. Stellar got it done. The EP Cube ties into our existing solar and our Generac standby, and the system manages itself — solar by day, battery at night, generator as final backup. We don’t worry about outages anymore.”
Every project handled in-house by our Red Seal Master Electrician and the Stellar Upgrades crew — 550+ installs since 2018.
Four steps. Typically 4–6 weeks.
Free assessment
Your panel and garage wall get a proper look, we map out the circuits you want backed up, size the right EP Cube for your loads, and put your exact all-in price in writing. No obligation.
Engineering & permit
Our team prepares the drawings and our in-house Red Seal Master Electrician pulls the Strathcona County electrical permit — the Park's actual permit authority, not the City of Edmonton.
One-day install
Mounting, wiring, the panel tie-in and switchover configuration all happen in a single on-site day — and battery-only work needs no FortisAlberta meter swap.
Inspection & commissioning
County inspection, commissioning, and EP Cube app setup on your phone. From signed agreement to commissioned battery, plan on 4–6 weeks in total.
Every permit carries a Red Seal Master Electrician's name.
Because a home battery ties into your main panel and reconfigures how your home takes power, the law requires its electrical permit to be pulled by a licensed electrical contractor. Stellar's in-house Red Seal Master Electrician is named on every permit we pull, in Strathcona County and everywhere else we work. Nothing is subcontracted — the same crew that quotes your battery is the one that installs it. Batteries are wall-mounted in the attached garage in most Park homes — the standard location under Alberta STANDATA Variance 21-ECV-064-900-ESS, with capacity capped at 20 kWh per unit and 40 kWh per dwelling by CEC Rule 64-918.
In-house, on payroll
Our Master Electrician of record supervises every certified electrician on the job. No subcontractors on any residential install, ever.
$5M insured · BBB A+
We carry $5M in general liability coverage, BBB A+ accreditation and current WCB clearance, and have operated since 2018 with the same Master Electrician on every permit.
Code-first installs
Mounted in the attached garage under Alberta STANDATA Variance 21-ECV-064-900-ESS, sized to CEC Rule 64-918, built with NEMA 4X-rated hardware, and covered by Canadian Solar's 10-year / 6,000-cycle warranty.
