Standby Generators for Sale

Standby generators for sale in Alberta, for when the lights go out.

A backup set you own, waiting behind the building until the utility fails. Natural gas, propane and diesel units are listed below with their full specs, and each is priced in writing from Red Deer.

More than the generator

A standby system is four purchases.

Buyers often price the set and stop there. Backup power only works when all four pieces are in place, and three of them come from someone other than the generator seller.

01

The generator

The set on this page. It sits idle almost all the time, so what matters is that it starts every time and can take the load it is meant to carry.

02

The automatic transfer switch

Senses the outage, starts the set and moves the load across. It is sized to the building's service and bought through your electrician or their supplier. We rent switches but don't list them for sale.

03

The fuel supply

A gas line and meter large enough for the engine at full output, or a diesel or propane tank big enough for the longest outage you plan for.

04

The installation

A pad or room, the wiring, the gas connection and the permits. That is licensed work: an electrician for the switch and cable, a gas fitter if the set burns the building's gas.

How the switch hands the load over, and how standby ratings differ from prime, are covered on emergency standby generator rentals.

Choosing by fuel

What each fuel asks of the owner.

A rented set comes and goes with its fuel handled. An owned one keeps its fuel on the property for years, and that shapes the choice as much as the engine does.

Natural gas

Nothing to store or rotate, and the set runs as long as the line delivers. The question to settle is whether the gas service will hold up in the event you are buying for, and whether the meter can supply the engine at full load.

Propane

Keeps in the tank for years without going off, which suits a set that may sit unused for a long time. Runtime is set by the tank, and a large propane tank has its own siting rules.

Diesel

Independent of any utility, with the fuel right there in the base tank. Stored diesel ages, collects water and can gel in cold weather, so an owner needs a plan to test, treat or turn it over.

For sale now

Sets that can stand by, smallest first.

Every generator currently listed for sale, grouped by fuel and read from the inventory when the page loads, so a sold unit drops off. Compare each card's voltage with the rating on your building's main service.

A set that spent its life on standby can have very few hours on it, which is worth knowing when you look at used generators for sale. For a business buying a set for any duty, see commercial generators for sale.

After it is installed

A standby set is only as good as its last test.

It may go months without a real outage, which is exactly why problems hide. Prove the whole system on the day it goes in, with the switch transferring and the set carrying a real load for long enough to settle. A rented load bank does this where the building can't supply the load.

After that, regular exercise runs and planned service catch the usual culprits: a tired battery, a block heater that has quit, stale fuel. Our technicians work on other makes as well as our own.

Budget not there yet?

Put it in on rent, buy it later.

These units are offered rent to own, so the building is covered now and the rent paid counts toward the purchase if you keep the set.

Standby buyers ask

Before you buy backup power.

Do you sell the automatic transfer switch as well?

No. Transfer switches are in our rental fleet, not for sale. A permanent switch is matched to the building's main service and usually bought by the electrician who installs it. If the generator arrives before the switch, a rented switch can bridge the gap.

How big a standby generator does my building need?

First decide what it has to carry: all of the building, or only the loads that cannot stop, such as freezers, servers, pumps, heat and exit lighting. List those with their running amps or kW and note the largest motor. The amperage calculator turns amps into kW, and we will check the list against the sets on this page.

Is a natural gas standby generator dependable enough?

Gas reaches the building through a separate system from the electricity, so an electrical outage on its own doesn't stop it, and a gas set never runs out of stored fuel. Where the outage you are guarding against could also cut the gas, or the meter is too small for the engine, diesel or propane is the safer choice. Several listed sets, the NPI-250 and NPI-350 among them, are dual-fuel and run on natural gas or propane.

How often should a standby generator run when there is no outage?

On a regular schedule, under load, so that faults show up on a test day rather than during an outage. The manufacturer's schedule is the starting point, and a code-required emergency system has its own testing rules under CSA C282. Planned service and load bank testing are both on our generator service page.

Will it start on a cold Alberta morning?

A standby set outdoors in winter depends on a working block heater, a charged battery and fuel that hasn't gelled. Check the listing for what the unit already has, and ask if it doesn't say, so you know what still needs adding before winter.

What does a standby generator cost once it is installed?

The set is only part of it. Add the transfer switch, the electrical and gas work, a pad or enclosure, permits and the first fuel fill. We price the generator itself in writing; your electrician quotes the rest, and comparing both before you commit gives the real number.

Whether a purchased set can serve as a building's code-required emergency power is for its engineer and the local authority to decide, under CSA C282.

Find the set behind your building.

Tell us the service voltage, which loads must stay on, what fuel the site has and where the set will sit. We will match a listed unit and put a price on it, or say so if none of them suits.
