An ice storm caused the first blackout in our new home in rural Quebec. I was working at home as usual, with no way to email, message, or call out. As the hours stretched on, growing colder and more anxious, I finally bundled up and braved my way to the nearest house. As I approached the house, a deafening noise greeted me like a lawn motor for the Jolly Green Giant; it was a gasoline-powered generator. But fortunately, they weren’t giants, or serial killers. These lovely people let me charge my phone, join them for pizza, and stay put until the evening, when power was restored and my family returned.
We’d considered buying a generator after moving from Montreal to the country. But we were trying to live green, and we couldn’t think of a less sexy item on which to spend our hard-earned dollars. However, after that storm, we realized our very survival could depend on having backup power. So, steeling ourselves for complications, expense, and technical hell, we reworked our budget and started researching portable generators.
I hope these tips will make your process easier, faster, and less painful than mine. A really great find was this glossary of terms in the portable generator world (http://www.omafra.gov.on.ca/english/engineer/facts/00-057.htm).
Please note that this article is specific to portable generators.
Quick Navigation
What To Look For In A Generator
1. Gas, Propane, Diesel, or Solar?
Before I started researching, I wondered if there was such a thing as a solar generator. Thank goodness the power was on that night because I discovered online that yes, there was, and that there were many for sale.
But let me back up. What about gas or diesel, the most popular portable generators?
Plus:
– Size/capacity. These are big beasts, some oozing with wattage. Many can run your fridge, your computer, and your phone, perhaps even your heating and cooling systems.
Minuses:
– Storing fuel (precious garage or shed space);
– Must be run outdoors (toxic fumes);
– Spillage could cause a serious fire;
– Limited shelf life (gas is about one year);
– Fuel is non-renewable ($$$);
– In survival situations, fuel is scarce; and
– Noise: as in, louder than a high school keg party, although some manufacturers are advertising quieter motors.
And Propane?
Pluses:
– Cleaner;
– Cheaper;
– Quieter;
– No problems with spillage (propane evaporates); and
– Fuel has indefinite shelf life
Minuses:
– Poor performance in cold weather;
– Engines have more problems; and
– Nonrenewable ($).
And Solar? ![PowerUpWorld - solar generator](data:image/svg+xml;nitro-empty-id=MzYxOjg0NQ==-1;base64,PHN2ZyB2aWV3Qm94PSIwIDAgMzAwIDE2NiIgd2lkdGg9IjMwMCIgaGVpZ2h0PSIxNjYiIHhtbG5zPSJodHRwOi8vd3d3LnczLm9yZy8yMDAwL3N2ZyI+PC9zdmc+)
Pluses:
– Runs indoors safely;
– Silent as a monastery; and
– Renewable energy resource (more moola for fun).
Minuses:
– Much lower power capacity; and
– Can charge while in use but dependent on the sun, who doesn’t always cooperate.
There are also generators that combine gas and propane (known as “hybrid,” “dual system,” or “dual fuel”). These are beyond the scope of this article. Check out our top rated dual fuel generators here.
2. Expense
Portable generators run from between $400 and $4,000USD, so budget is another important consideration
With fuel-powered generators, more power means more money. Want continuous power for hours or days? You’ll pay a pretty penny for that too. You’ll also pay for a quieter motor.
Solar panels that collect up to 100 watts of electricity are costlier than those whose capacity is 50 watts. Also, light weight models with higher wattages have a higher price tag.
3. Size/Power Output
It’s about number of outlets and power output capacity. First figure out the power requirements for the appliances and electronics in your home. These are average figures for some common appliances:
- Refrigerator: 600 watts
- Sump pump: 750 to 1,500 watts
- Portable heater: 1,500 watts
- Window air conditioner: 1,000 watts
- Lights: 60 to 600 watts
- Computers: 60 to 300 watts
Most appliances have labels with their power requirements, but it’s a good idea to consult an electrician. Also consider what basic power needs you’d have in a survival situation. Not sure about you, but I don’t see myself trolling on Facebook and making a smoothie while watching floodwaters rise and trees fall outside my kitchen window.
4. Performance
How well does the generator function? Most models give you the number of hours they’ll run on a tank of fuel or at full battery capacity; note that there’s a difference between continuous rating, which is how much power your generator can supply continuously, and maximum rating, what the generator can supply for short periods of time. Definitely look at warranties as the idea is to have something that will be around for the long term. Also look at what the generator is made of. Steel is a solid choice. Many reviews look at tires on wheels since they can go flat. Starters for gas generators can also malfunction so it’s good to know a model’s history before you make your purchase.
5. Portability
Seems obvious but it’s often overlooked. At 20 pounds, pretty much anybody can lug our generator around as necessary. For camping the Yamaha EF2000iSv2 is one of the lightest and quietest portable generators, and provides between 1600 and 2000 watts of power. But at 44 pounds, the thing weighs more than a four-gallon bottle of filtered water. The DuroStar 4,400 watt weighs 138 pounds. Does that sound like portable to you?
6. Add-ons and Extras
Anyone who’s made a big purchase has gone through that massive list of features. For us technically challenged sorts, even understanding what the features are or what they do can be daunting.
Want your portable generator to run your entire home’s electricity needs? If that includes 220-volt appliances like dryers and stoves for a total wattage of 5,000 or more, you must have a transfer switch or an interlock device. This connects the generator to your circuit panel. If you lose power and want to transfer to your generator, you’ll need to flip a switch so the system knows the power source has changed. You’ll need an electrician and it ain’t cheap: according to my research, between $500-$900USD. Interlock devices run a few hundred cheaper and are easier to install. But this is absolutely necessary, since there are safety risks without it, to you, to workers making repairs, and to your appliances, including your generator.
Other features and add-ons: automatic starts, electric start for gas generators, wheels to help move the heavier beasts, fuel gauges, a gas can, fuel stabilizer, ground-fault circuit interruption, economy mode switch, low-oil shutoff, multiple outlets (if you have an electric car, make sure there’s a car charger outlet), weather-resistant storage covers, and a removable console. A gen-cord means just one cable between the generator and the house (more important for fuel-powered machines, when the generator is further away from devices).
With solar, you can purchase more panels and switch them off during a longer survival situation.
7. Safety and Local Regulations
If you’re in a crisis, the last thing you need is danger. The EPA regulates generators for emissions levels, since the fumes can be lethal. California has an even tougher law You’ll find compliance with either the EPA or CARB noted on the packaging. Purchase a California-compliant model for maximum safety, regardless of where you live.
Portable generators offer peace-of-mind, knowing that in an emergency, you have a limited power source for necessities. My advice would be to KISS (keep it simple, stupid). It’s hard to predict what will happen with climate change, but if we invest a bit of time and money, survival is a heck of a lot more likely.
