An EP Cube 2.0 battery and its inverter on the outside wall of a home, beside a Generac standby generator on its pad

Whole-home backup · Edmonton & Alberta

Whole-home backup: solar, a battery and a Generac generator.

Solar and an EP Cube battery take over the moment the grid fails. Add a Generac standby generator and the house keeps running for as long as the outage lasts: the generator starts itself when the battery runs low, refills it and shuts off.

In an outage

What happens when the grid goes down.

Nothing for you to do. The system works through it in this order.

A home with its lights on at night during a neighbourhood power outage, an EP Cube battery on the outside wall

The moment it fails
The battery takes over
In under 20 milliseconds, before a light can flicker. No gap, no noise.
By day
Solar refills the battery
Your panels keep charging the battery while the sun is up, even with the grid down.
If it runs low
The generator starts itself
At 10% the Generac starts on its own, refills the battery to 100% and shuts off. Ultimate only.
When power returns
Back to normal, on its own
The system reconnects to the grid and goes back to banking your solar.

What we install

Built for an Alberta winter.

Three pieces of hardware, one system. The battery and its inverter are the Elite package; the generator makes it Ultimate.

Inside a Generac Guardian standby generator: the engine, its starter battery and the controls

1 · Standby generator, Ultimate package

Generac 18 kW, on natural gas

For the outage that lasts days, not hours. When the battery runs low the generator starts itself, runs the house and recharges the battery, then shuts off. It runs on your natural gas line, so there is no fuel to haul. The battery still does the instant switch-over, so the lights stay on while the generator starts.

Warranty5 years, Generac

2 · Battery backup, optional

EP Cube 2.0, 5 to 40 kWh

Slim towers on the garage wall. By day they soak up your surplus. By night they run the house, so you buy almost nothing from the grid. When the grid fails, they take over before a light can flicker.

Warranty10 years

Output at onceUp to 11.5 kW per tower

ExpandableUp to 40 kWh

Battery spec sheet

3 · Hybrid inverter, battery packages

EP Cube hybrid inverter, 11.5 kW

When you add a battery, one hybrid inverter runs the panels and the battery together. It decides, every second, whether the roof’s power goes to the house, into the battery, or to the grid, and it is what switches the house over in an outage.

Battery, or battery and generator?

The difference is the long outage.

Both bundles handle the moment the grid fails. The generator is for the outage that lasts days, in the dark of winter.

	Elite: solar + battery	Ultimate: solar + battery + generator
When the grid fails	The battery takes over in under 20 milliseconds	The same
A long outage with little sun	Runs until the battery is empty; solar refills it by day	The generator refills the battery whenever it runs low
What powers it	Your solar, stored in the battery	Your solar first, natural gas as the reserve
Noise	Silent	Silent, except while the generator runs
Lowers your bill day to day	Yes: the battery stores your solar for the evening	Yes, the same; the generator adds backup, not savings
Warranty	Battery: 10 years	Battery: 10 years · Generac: 5 years

Fair questions

Asked straight, answered straight.

Elite is a solar system with an EP Cube battery: the house runs on its own power most of the time and keeps running when the grid stops. Ultimate adds a Generac standby generator, so it keeps running for as long as the outage lasts. Same panels, same battery, same crew.

It follows the battery. When the battery falls to 10%, the Generac starts itself, runs the house and refills the battery to 100%, then shuts off. Nobody has to go outside in the dark.

No. The battery takes over in under 20 milliseconds, before a light can flicker. A standby generator on its own takes 10 to 30 seconds to start and switch over; with the battery in front of it, you never see that gap.

Natural gas, from your home’s existing gas line, so there is no fuel to store or refill. It sits on a pad next to your gas meter. We confirm the spot at the free assessment.

For Ultimate: the Generac 18 kW standby generator, its pad, the gas and electrical connections, a cold-weather kit and the permits, on top of everything in Elite: the solar system, the EP Cube battery and its hybrid inverter. Your written design shows one price for your home.

Generac: a 5-year limited warranty. EP Cube battery: 10 years or 6,000 cycles, to at least 80% of its original capacity. Our workmanship: 10 years on Elite and Ultimate.

Yes. It is not either/or: the EP Cube 2.0 has a generator input, and we have integrated EP Cube batteries with existing standby generators. The battery handles the instant switch-over and daily backup; your generator becomes the deep reserve.

Every home needs a different size of system, so the price is per home. You get one written price for your home at the free assessment. The price we quote is the cash price; a financed price includes the lender’s finance and transaction fees, shown in the written offer.
