Types of Home Backup Generators
Home backup generators come in several forms, each designed to meet different power requirements. Exploring their features and capabilities will help you determine whether the best portable generator for home backup power or a larger standby system is the right choice for your home.
Standby Generators
Standby generators, also known as whole-home generators, are permanently installed and automatically restore power during an outage. Running on natural gas or propane, they can power most or all of your home, including heating, cooling, and major appliances. With outputs typically ranging from 5,000 to 20,000 watts, they offer the highest capacity and convenience. However, they are the most expensive option and require professional installation, permits, and adequate outdoor space.
Portable Generators
Portable generators are an affordable backup power option that requires no permanent installation. Typically fuelled by gasoline, propane, or both, they provide 3,000 to 8,500 watts, enough to run essential appliances during short-term outages. Many models include wheels for easy transport, making them suitable for home, work, or camping. For safety, always operate a portable generator outdoors, at least 6 metres (20 feet) from your home, to prevent carbon monoxide exposure.
Portable Inverter Generators
Portable inverter generators provide clean, stable power, making them ideal for sensitive electronics such as laptops, smartphones, and medical devices. They are quieter and more fuel-efficient than conventional portable generators because they adjust engine speed to match demand. Most models produce 900 to 7,600 watts, enough to power essential appliances during an outage. Although they cost more, they offer quieter operation and improved fuel economy.
Portable Power Stations (Solar and Battery Backup)
Portable power stations store electricity in rechargeable batteries and typically provide 1,800 to 6,000 watts of power for essential devices and appliances. They can be recharged from a wall outlet or compatible solar panels, making them a clean, fuel-free backup option. Because they produce no emissions or carbon monoxide, they are safe for indoor use. While quieter than generators, they offer shorter runtimes and require periodic recharging.
Fuel Type Comparison for Canadian Winters
The type of generator is only part of the decision. Choosing the right fuel is equally important, especially for reliable performance during Canada's cold winters and extended power outages.
Gasoline
Gasoline generators are affordable and widely available, making them a popular choice for backup power. However, gasoline degrades over time, requires careful storage, and may be harder to find during major outages. They also produce more noise and emissions than other fuel types, making regular maintenance and proper fuel management especially important during Canadian winters.
Propane (LPG)
Propane (LPG) is a clean-burning fuel with a long shelf life, making it well suited for backup power during Canadian winters. Unlike gasoline, it does not degrade during storage, making it ideal for occasional use. Although slightly less fuel-efficient, propane produces fewer emissions and offers reliable performance when stored in dedicated tanks.
Natural Gas
Natural gas is a clean-burning, efficient fuel that provides a continuous supply without requiring on-site fuel storage, making it ideal for extended outages. However, generators depend on the local gas supply, which may be interrupted during emergencies. They also require regular maintenance to ensure safe, reliable operation.
Solar Power
Solar-powered backup systems generate electricity from sunlight and work best when paired with a home battery system for energy storage. They produce no emissions and reduce fuel costs, making them an environmentally friendly option. However, their performance depends on sunlight, so they may provide less power during Canada's short winter days or prolonged storms.
How Do You Calculate What Size Generator You Need?
Generator size directly affects how many appliances you can run during a power outage. Calculating your home backup power needs helps you choose a generator with the right capacity.
Step-by-Step Wattage Calculation
Before choosing a generator, it’s important to accurately estimate your home’s power needs so you can avoid overloads and ensure reliable performance during outages in Canadian conditions.
-
List essential appliances you want to run during a power outage, such as your refrigerator, furnace, lights, and sump pump.
-
Find each appliance's running and starting wattage, as motors may require 2–3 times more power to start.
-
Add the running watts, then include the highest starting wattage to estimate your peak power requirement.
-
Add a 10–20% safety buffer to avoid overloading the generator and allow for future power needs.

FAQs
Are inverter generators better for home backup?
Yes, inverter generators are often a better choice for home backup if you need to power essential appliances and sensitive electronics. They produce clean, stable electricity, run more quietly, and use fuel more efficiently than conventional portable generators. However, they typically cost more and provide lower power output, making them best suited for partial home backup rather than powering an entire house during extended outages.
Can I run my house on a 6000 watt generator?
Yes, a 6,000-watt generator can power many essential household appliances during a power outage, including a refrigerator, freezer, lights, television, microwave, and sump pump. Depending on your home's electrical load, it may also support a small HVAC system. However, it usually cannot run every appliance simultaneously, so you'll need to prioritise essential circuits to avoid overloading the generator.
How much is a generator for a 2000 sq ft house installed?
For a 2,000 sq. ft. home in Canada, installing a backup generator typically costs $5,000 to $12,000, including the generator, labour, permits, and electrical work. The right size depends on your power needs, but most homes require a 7–22 kW system. If you only want to run essential appliances, a smaller generator may be sufficient, while whole-home backup generally requires a larger unit.
