The Ultimate Checklist for Choosing a Home Backup Generator
In Canada, unpredictable weather is part of life, from blizzards in the Prairies and ice storms in Ontario to heavy winds on the East Coast. Power cuts can last a few minutes, a few hours, or in some cases several days, leaving households without heating, lighting, or even a way to charge essential devices. That’s where a home backup generator becomes more than just a convenience; it’s a safeguard for comfort and safety. With countless models and features to sift through, it can feel overwhelming to know which one suits your needs best. This checklist will help you cut through the noise by breaking down the essential considerations, from power capacity to fuel type, so you can choose a generator that fits your household and ensures you’re never left in the dark.
What Are the Types of Home Backup Generators?
Before narrowing down your options, it helps to know the main types of home backup generators available in Canada. Each comes with its own advantages and trade-offs, depending on your budget, household needs, and how you plan to use it.
Standby Generators
These are the heavy-duty, hands-off solutions for homeowners who want total peace of mind. Permanently installed outside, standby units connect directly to your electrical panel and kick in automatically within seconds of a blackout. They’re usually fuelled by natural gas or propane, making them ideal for long outages since there’s no need to worry about topping them up. While they come with a higher price tag and require professional installation, they’re the most reliable choice for whole-home coverage.
Portable Generators
Portable models are the go-to for flexibility and affordability. Running on gasoline, they provide enough power to keep essentials like fridges, lights, and sump pumps running during an outage. They do require manual start-up and regular refuelling, but their portability means they can double as a power source for camping trips or outdoor projects. Many Canadian households strike a good balance between cost and convenience.
Inverter Generators
If you want quiet operation and safe power for electronics, inverter generators are worth considering. They adjust their engine speed to meet demand, which makes them both fuel-efficient and less noisy than standard portable models. Because they produce “clean” electricity, they’re perfect for laptops, phones, and other sensitive devices. While their power capacity is generally lower than a traditional portable, their efficiency and low sound levels make them especially appealing in suburban or urban neighbourhoods.
Solar Generators
Eco-friendly and silent, solar generators are gaining traction in Canada, particularly as households look for greener backup options. These units are essentially large battery packs that can be recharged via solar panels, a wall socket, or even a car outlet. They’re best suited for short-term needs, such as charging phones, laptops, or running smaller appliances. Although they can’t yet replace the raw output of fuel powered generators, they’re a clean, emission-free option and an excellent complement for emergency preparedness.
Checklist for Choosing a Whole House Generator
Picking the right whole-house generator goes well beyond brand names; it’s about matching the machine to your household’s actual needs. Here are the key factors Canadians should weigh before investing in one.
Power Output
Measured in watts, power output is the most critical spec. To avoid overload, calculate the combined wattage of the appliances and systems you’ll want running at the same time, from fridges and furnaces to well pumps and freezers. Remember to account for starting watts (the surge appliances need to kick on) as well as running watts (what’s required to keep them going).
Battery Capacity
For solar and battery-based systems, storage is everything. Capacity, measured in watt-hours (Wh), determines how long your generator can run essential items during an outage. The higher the capacity, the more reliable your setup will be in long blackouts, particularly useful in rural areas or regions prone to extended winter storms.
Uninterruptible Power Supply (UPS)
If you rely on sensitive electronics, like a home office setup or medical equipment, a generator with UPS capability is a must. It ensures a smooth transition to backup power with no interruptions or damaging surges when the grid drops, offering reassurance that your critical devices will stay safe and online.
Multiple Charging Options
Flexibility matters during an outage. A strong system should be able to recharge from more than one source: wall outlet, vehicle, or solar panels, so you aren’t stuck if one option fails. This feature is especially handy in remote parts of Canada where utility repair can take days.
Solar Compatibility & Efficiency
If you’re leaning green, pay attention to solar input. A higher wattage input means faster charging through panels, while efficiency dictates how well the system captures and stores that energy. In sunnier provinces like Alberta or southern Ontario, this can make a big difference in performance.
Noise Levels
Traditional gas-powered generators can be loud enough to disturb the household and the neighbours. Standby models tend to be quieter than portables, while inverter generators are a more neighbour-friendly compromise. If silence is a priority, solar generators are by far the quietest option.
Battery Life & Chemistry
The chemistry of the battery determines both safety and longevity. Lithium Iron Phosphate (LiFePO4) batteries, now common in modern portable stations, last much longer and are more stable than older lithium-ion alternatives, making them a more dependable long-term investment.
Scalability
A generator should grow with your needs. Some systems allow you to connect extra batteries or modules to increase total capacity and power output. This scalability is invaluable if your household expands or if you want to upgrade your backup system gradually instead of replacing it outright.

What Can Go Wrong with a Home Power Generator?
Even the best home backup generator isn’t immune to problems, and knowing what can go wrong helps you stay prepared and avoid costly repairs.
Startup Issues
One of the most common frustrations is a generator that refuses to start. With fuel-powered units, stale fuel or a clogged filter is often to blame, while solar and battery-based systems usually fail due to a depleted battery or faulty component. Keeping fuel fresh, charging batteries regularly, and doing seasonal checks are simple ways to prevent these headaches.
Fuel Problems
Gasoline doesn’t age well. Over time, it breaks down, clogs the carburettor, and makes the generator sluggish or unreliable. In Canada, where many homeowners only pull out their generator during storms or winter outages, stale fuel is a regular issue. Using fuel stabilizers or running the unit dry before storage can save you a lot of trouble.
Overloading
Plugging in more than your generator can handle is another frequent mistake. Overloading can trip breakers, damage appliances, or even harm the generator itself. The best way to avoid this is by calculating the wattage of your essentials and making sure your generator has the headroom to handle both running and starting watts.
Mechanical Failures
Like any machine, generators have moving parts that wear out. A broken fan belt, clogged air filter, or faulty voltage regulator can leave you without power when you need it most. Sticking to a regular maintenance schedule helps prevent these failures.
Location & Installation
Improper setup can create serious risks. Gas-powered models must be run outside, never in garages or basements, to avoid carbon monoxide poisoning. Solar generators and battery-based stations, however, don’t produce emissions, making them a safe, quiet alternative for indoor use.
Safety Risks
Beyond carbon monoxide, generators pose fire hazards if hot parts come into contact with flammable materials, and they can cause electrocution if used with improper cords or without a transfer switch. Following safety guidelines is essential to keep both your home and family safe.
Lack of Maintenance
Finally, neglect is often the biggest culprit. A generator left untouched for months or years can lose efficiency or fail when you finally need it. Whether fuel-based or solar, all generators require regular upkeep to ensure they’re ready to step in during an emergency.
FAQ
How to size a backup generator for my home?
The first step in choosing the right generator is figuring out how much power you actually need. Start by listing all the essentials you want running during an outage, think refrigerator, lights, furnace, sump pump, and maybe a few electronics. Check the running wattage for each item—for instance, how much power is indicated by the toaster’s wattage—and add them together for your base load. Next, find the starting wattage (the surge needed to turn an appliance on) and add the highest one to your total. To be safe, build in an extra 20–25% buffer so your generator can handle unexpected surges or the addition of another appliance. This way, you’ll have a unit sized not just for today’s needs, but with a little flexibility for tomorrow.
